Opus 4.7, Claude Design, Qwen 3.6, Hermes and more

In the LLM world, Context Rot is what happens when a model takes in so much noisy, stale, or fragmented information that its understanding starts to break down. And honestly, the same thing happens to us. This is an AI-generated podcast built to help you keep up with the latest in AI. Every week, we'll synthesize what AI experts in the timeline are talking about so you can protect your own context window. Get the latest in AI on the go. What happened, why it matters, and what to watch next. This is Context Rot. This week, we have a lot of ground to cover. Anthropic launched Opus 4.7 and Claude Design. Depending on who you ask, it's either the beginning of the end for Figma or just a really fast mood board generator. Alibaba dropped Qwen 3.6, a model that runs at over 100 tokens per second on a consumer GPU and is apparently making a lot of developers rethink their API subscriptions. Hermes Agent just shipped two major versions in three days and is now in a full-on arms race with OpenClaw for the title of top open source agent framework. Cerebrus filed an IPO with actual profits, which in this industry is genuinely unusual. And that jailbreak study. We'll get to all of it. Let's start with Anthropic because this is the story that generated the most heat this week among designers, PMs, and basically anyone who has ever had to sit in a meeting waiting for a Figma mock-up. So on April 17th, the same day they made Opus 4.7 generally available, Anthropic launched Claude Design. It's an Anthropic Labs research preview, meaning not the polished commercial product, but the here's what we're building version. It's available to pro, max, team, and enterprise users. And what it does is generate polished visuals, interactive prototypes, pitch decks, one-pagers, and marketing assets from natural language descriptions. You describe what you want, it builds it. You iterate, it refines. You apply brand guidelines, it stays on them. And then, here's the part that makes the workflow collapse. You hand it off directly to Claude Code for implementation. Design to code in one continuous pipeline. Now, to understand why this matters, you have to understand where Anthropic has been going for the past year or so. They've been systematically moving up the value stack. Claude started as a chat interface. Then Claude Code turned it into a serious engineering tool. Artifacts brought interactive rendering. And now, design is the wedge into the creative and product layer. This isn't a company that wants to be infrastructure. They want to be the operating system for knowledge work. That's the play. And the timing isn't arbitrary. There's a capability threshold that models have been approaching. Reliable, high-resolution vision. Long-horizon task execution. Genuine instruction following across multi-turn refinement loops. Opus 4.7 is reportedly handling images up to about 3.75 megapixels. It follows instructions more literally than 4.6, which in a design context means it actually does what you asked instead of making creative substitutions you didn't want. On the agentic coding benchmarks, SWE Bench Verified is at 87.6%, SWE Bench Pro at 64.3%, Terminal Bench at 69.4%. These are meaningful numbers for anyone building on top of the model. Pricing stayed the same as 4.6. $5 per million input tokens. 25 out. Though there's a catch. A new tokenizer apparently uses up to 30-35% more tokens for similar prompts, so your actual costs may be higher than that headline suggests. The community reception was enthusiastic, with a sharp divide running through it. Designers and PMs were mostly excited. A lot of engineers immediately asked the Figma question. And then Simon Willison showed up with something that cut through the noise in a different direction entirely. If you don't follow Simon Willison, handle at Simon W, he's one of the most consistently useful technical voices on AI tools and safety. Within a day of the launch, he published a diff analysis comparing the Opus 4.6 and 4.7 system prompts. He built a tool to extract and diff these prompts, and what he found gave the engineering community a rare, structural look at how Anthropic is actually steering this model differently from its predecessor. The changes in the 4.7 prompt emphasize more constrained safety behavior, more literal prompt interpretation, and explicit self-verification mechanisms, meaning the model is being told, at the system level, to double-check its own outputs before returning them. That's not a small behavioral change if you're building production systems on top of it. Willison's analysis matters because behavior shifts between versions can break production prompts in subtle ways. And from the community response, that's exactly what people are running into. Setups that worked cleanly on 4.6 are behaving differently on 4.7, not because the model is worse, but because it's interpreting instructions more strictly. On benchmarks, one account called AtScaling01 pointed out something interesting. They posted, Which, if accurate, is a meaningful decision. It would mean Anthropic is choosing not to publish some capability numbers they have internally, presumably because the cybersecurity capability threshold is one they're being deliberately cautious about. That same account cited an internal Anthropic survey on something called Claude Mythos Preview. Over 50% of respondents said that Claude Mythos already has, or will likely have, L4 taste with scaffolding in the next three months, and separately noted a geometric mean productivity uplift of 4x in internal assessments. L4 taste is a community term floating around for the design sensibility required to produce outputs that a senior design professional would consider genuinely excellent, not just competent. The framing of Mythos as a more powerful model that Anthropic is deliberately holding back, using 4.7 as a safer staging ground, is an interesting one. Whether or not that's accurate, the breadcrumbs are there in the system prompt changes and the community buzz around the Mythos name. So what's actually at stake for the design industry? The honest answer is, it depends on the use case. Claude design, from early reports, is excellent at speed and polish on first drafts. It produces things that look good, fast. What it may not do yet is produce things that feel deeply original or contextually nuanced in the way that experienced designers bring to work. One framing that keeps coming up is augmentation for now. It handles the rapid ideation, the polished draft, the first-pass prototype that you'd otherwise spend a day in Figma producing. That unlocks something real for founders, PMs, and engineers who don't have design resources. But the gap between really fast first draft and genuinely displacing Figma is still substantial. Figma has 15 years of professional workflow embedded in it. The question is how fast that gap closes, and whether Figma responds with something that changes the equation before it does. The thing I'd watch for is Figma's move in the next few weeks, because if Claude design has real retention, if users keep coming back to iterate rather than just playing with it once, that's the signal that something structural is shifting. Now let's talk about Alibaba, because this one is directly practical for anyone who has an RTX 4090 sitting under their desk, or who has been watching their API bills and wondering if there's a better way. On April 16th, the Quen team open-sourced Quen 3.635BA3B. The name is a mouthful, but here's what it means in plain language. 35 billion total parameters, but only 3 billion active on any given token. That's a sparse mixture of experts' architecture. The model has 256 specialized expert subnetworks, and for each token it processes, the router selects a small subset of those experts rather than running the whole thing. The result is that the model has the knowledge capacity of a much larger system, but the computational cost of a much smaller one. And the numbers on this are genuinely striking. At 4-bit quantization on an RTX 4090, this thing runs at over 110 tokens per second. It fits in 16 to 24 gigabytes of VRAM. It supports a context window up to 262,000 tokens. It handles multimodal inputs, vision, and language. It has thinking and non-thinking modes, which is important for agentic tasks where you want the model to reason through a problem before committing to an action. And there's a preserve underscore thinking flag that maintains the reasoning state across multiple turns in an agent loop, which is a detail that sounds minor until you've watched an agent lose its chain of thought between tool calls and start going in circles. The benchmark story here is real, but requires some care in how you interpret it. On SWE Bench Verified, which tests the ability to fix real GitHub issues in real code bases, the model hits 73.4%. Its predecessor, the 3.5 version at the same parameter scale, was at 70%. The competing Dintz-Quinn model at 27 billion parameters is at 75%. GIMMA 4 at 31 billion is at 52%. And on Terminal Bench, which tests agentic command line task execution, this model scores 51.5 against 42.9 for GIMMA 4 and 41.6 for the 27B Dintz version. AIM 2026, the math competition benchmark, comes in at 92.7%. These are not paper numbers constructed to look good in a press release. Community testers are reporting results that match. The developer community response has been notable. The volume of, I replaced Claude Sonnet in my workflow with this posts has been substantial. And you have to understand the context that makes that credible. Claude Sonnet over the API is not free. It has latency. It has rate limits. And for developers building autonomous agents that make lots of sequential calls, those factors matter. Running a capable model locally at 110 tokens per second with no rate limits is a qualitatively different experience. Simon Willison actually put out a fun comparison. Here's Quinn 3.635BA3B versus Claude Opus 4.7 for generate an SVG of a flamingo riding a unicycle, in case you thought Quinn might be cheating at the Pelican benchmark. Which is a very Willison way of making a serious point, that Quinn's benchmark performance holds up on the silly creative tasks too, not just the structured coding evals. Now there's context behind the Quinn release that matters for understanding what it signals about Alibaba's direction. In March 2026, Junyang Lin, the longtime technical lead of the Quinn project, stepped down. Reuters reported it as part of a broader restructuring. The framing that's been circulating is a shift from what people are calling a vertically integrated lab model, where one research leader drives the technical vision, to an industrial chain factory model, which means more ecosystem integration, more production scale, more community leverage, less frontier research autonomy, more industrial execution. That's a real tension. The Quinn series has accumulated over a billion model downloads and more than 200,000 derivative models on Hugging Face. That's an extraordinary community flywheel. Whether the factory model sustains the pace of architectural innovation that got them here, or whether it trades frontier ambition for execution reliability, is a genuinely open question. The 3.6 release came quickly after restructuring, which suggests execution capacity is intact. But the real test will be whether the next generation of architectural ideas keeps coming. The architecture itself is worth a moment. The hybrid linear plus softmax attention with multidimensional rotary position encoding, MROPE, is what enables efficient, long context processing at this parameter scale. It's not just that they took a dense model and made it sparse. The attention mechanism is specifically designed to handle long sequences without the quadratic cost blowup that kills most transformer architectures at 100k plus token contexts. This is an architecture built for agentic use cases where context accumulates over many steps. Fully open weights, Apache 2.0 license, available on Hugging Face, on Olama, via the Alibaba Cloud API as Quen 3.6 Flash with OpenAI and Anthropic-compatible endpoints. The API pricing is reportedly Flash tier, which is the cheap tier, and community discussions suggest credits run at about 30% of direct API pricing for the Noose portal comparison. Though for Quen itself, the API costs are just cheaper baseline. The thing I'd keep an eye on here is the derivative ecosystem. When a model with this kind of quality lands with an Apache 2.0 license, fine-tuning activity on Hugging Face usually explodes within a week. What happens when people start fine-tuning this on domain-specific coding corpora, or on specific agent tool use patterns? The base model is already competitive. A well-targeted fine-tune of this architecture could push into frontier territory for specific use cases. That's the flywheel Alibaba is betting on. Okay, shifting to the open-source agent space, because there is a genuinely interesting competition developing here, and this week, it seems to have escalated. Noose Research's Hermes agent shipped version 0.9.0 on April 13th and version 0.10.0 three days later, on April 16th. The star count on GitHub is being reported variously as 32,000 and approaching 80,000, depending on who's counting and when. I'll say it's in the range of tens of thousands growing fast and leave it there. In either case, the velocity is what matters. Let's back up. Noose Research built its name through the Hermes model series, open models based on Lama and Mistral that were prized for instruction following and alignment quality well above what the base models delivered. That model post-training expertise is now the foundation of an agent framework. And the philosophy behind Hermes agent is distinctive in a specific way. It's built around a closed learning loop. The agent doesn't just use tools and execute tasks. It autonomously generates new skills from experience, optimizes them using techniques like DSPi and genetic evolution algorithms, and persists them for future use. Every interaction is potentially a contribution to the agent's accumulated capability. The idea is that over time, the agent gets measurably better at your specific workflows rather than starting from scratch each session. Version 0.9 was a substantial release. 487 commits, 269 pull requests, changes across 493 files. That's not a patch release. That's a platform. It added live model switching so you can change which underlying model the agent is using without restarting anything. Background notifications, cron automations, sub-agent delegation, meaning the main agent can spawn specialized sub-agents for specific tasks, and a one-command OLAMA setup that makes local deployment genuinely easy. Version 0.10 added the Noose portal, which is a subscription-based tool gateway. Web search via Firecrawl, browser automation, image generation through Flux and Fal, text-to-speech, all available without needing to configure and pay for individual API keys for each service. If you're a subscriber, you get the gateway bundled. Technium, who's the public face of Noose Research, put it plainly, the new XAPI CLI skill is now in Hermes Agent as well. Check out the PR or just run slash XURL with a prompt to perform actions and read and search tweets on Twitter, which is a small feature but illustrative of the pace. The framework is absorbing new capabilities continuously. Now, OpenClaw didn't sit still. They shipped three releases in 48 hours during the same period. And they got a significant visibility boost when Elon Musk tweeted about affordable XAPI access via OpenClaw, driving millions of views. The community read that as a marketing win rather than a technical differentiator, which is probably fair. Musk's endorsement doesn't change the code, but it does change the number of people looking at the GitHub repo. Andre Karpathy had probably the best framing for what's happening in this space right now. He wrote, LLM equals CPU, data, tokens, not bytes, dynamics, statistical and vague, not deterministic and precise. Agent equals operating system kernel. That analogy is doing real work. If the LLM is the CPU, then the agent framework is the OS. It handles scheduling, memory management, tool access, process isolation. The wars between Hermes and OpenClaw are, in this framing, OS wars. And Karpathy added another observation about why this moment feels different. Someone recently suggested to me that the reason the OpenClaw moment was so big is because it's the first time a large group of non-technical people who otherwise only knew AI as synonymous with ChatGPT as a website experienced the latest agentic models. That's a real insight about the adoption curve. The agentic interface is the first thing that's making AI legible to people who don't want to think about prompts. But here's the important piece of grounding that got somewhat lost in the enthusiasm this week. There's a benchmark called ClawBench. 153 real-world multi-step tasks on 144 live production websites. Finance, travel, development, etc. Not sandboxed environments, not curated demos, real websites. The top-performing model on ClawBench, Claude Sonnet 4.6, scores 33.3%, one-third, on tasks that any competent human assistant would handle without difficulty. For comparison, on the synthetic benchmarks that agent frameworks usually cite, Web Arena, OS World, you see numbers in the 65% to 88% range. The gap between 33% on real tasks and 88% on sandboxed benchmarks is the measurement of how much the current generation of agents still fails on the messy, unpredictable texture of the actual Internet. Neither Hermes nor OpenClaw has published ClawBench scores for their respective implementations, which is the number I'd be watching for. Because until we have that data, the framework comparisons are missing the most important variable. The architectural philosophy debate, self-improving loops versus production stability, is real and interesting. But if both systems are at 33% on real-world tasks, the philosophy discussion is somewhat premature. What matters right now is closing that gap. Okay, let's get to the jailbreak study because this one deserves its own space and it generated a lot of heat. Some of it signal, some of it noise. A study circulated on AI Twitter this week with a deceptively simple design. Take four AI reasoning models. Give each one a single instruction. Jailbreak this AI. Point them at nine major AI systems. Walk away. Come back and find a 97.14% success rate across all targets. No human guidance after the initial instruction. The models independently planned attack strategies, observed system responses, adapted their approach, and broke through. Let's sit with that for a second. Sigh. 97%. Across nine systems. With no human in the loop after the starting gun. The reason this is alarming, and people with safety expertise are right to be alarmed, is that the current generation of safety guardrails was designed with a human adversary model in mind. The assumption baked into most alignment and safety work is that the attacker is a person. Clever, persistent, maybe technically skilled, but ultimately bounded by human iteration speed and human creativity. What this study demonstrates is that when you replace the human attacker with a reasoning model, the attack surface changes fundamentally. An AI adversary can try thousands of variations in the time a human tries 10. It can notice subtle patterns and refusals. It can synthesize novel attack strategies that no human has tried before. Some engineers pushed back on the methodology. The argument is that models tested here weren't necessarily hardened against AI-native attacks. They were built to defend against human-generated jailbreaks, which have a different statistical signature. That's a fair technical critique. But the response to the attacker changed so our defenses don't work is update the defenses, not dismiss the study. And updating defenses against an adversary that iterates at machine speed is a substantially harder problem than updating them against humans. Researchers noted that transformer architectures have what you might call an intrinsic hackability problem. The models are, at their core, statistical pattern completers. They've been trained on enormous corpora of human text that includes everything, including text about how to do harmful things, including fictional framings, including the full spectrum of human persuasive and manipulative language. The safety training works by fine-tuning behavior on top of that base, but it's layered on, not fundamental. An adversarial system that can probe the boundary between the base model's knowledge and the safety fine-tuning has a lot of surface to work with. The broader context this week added weight to the story. There was a Molotov cocktail attack on Sam Altman's home. There were ongoing debates in the AI safety community about the value of activist pressure versus technical work. Framing this study in that context, which a lot of people did, probably distorted both the study and the broader safety discourse. The study is interesting on its own terms as technical evidence about adversarial robustness. It doesn't need to be a referendum on whether the AI safety movement is doing anything useful, and trying to make it one in either direction tends to obscure more than it reveals. The thing I'd keep an eye on here is whether this study prompts lab-level changes in red-teaming infrastructure. If safety teams are now running automated adversarial models against their own systems as a standard part of the hardening cycle, that's a meaningful operational shift, one that probably won't be announced publicly, but one that the people close to these organizations will notice. The alternative, treating this as a paper anomaly that doesn't require a response, seems increasingly untenable. All right, let's shift to what's been blowing up on GitHub this week. We already talked about Hermes agent in depth, so let me point to a few other things worth your attention if you're building. Quen 3.6-35b-a3b is fully available on Hugging Face as an open-weight download and through OLAMA. If you haven't looked at the OLAMA integration specifically, that's the lowest friction path to running this locally. The GGUF quantized versions are well optimized at this point, and the community has already started putting together model files that configure the thinking mode and preserve thinking flag for agentic setups. If you're doing any kind of autonomous coding agent work and haven't tried this on local hardware, that's a concrete thing to go check out. TransIP is getting attention in a more specialized community, but worth flagging. It's an open-source transformer architecture for molecular force fields. It learns physical symmetry directly in the model's embedding space, which removes the need for the pre-trained, then fine-tuned workflow that's been standard in molecular machine learning. The practical upside is that you can apply it to new molecular systems without starting from pre-trained weights. The star velocity isn't enormous in absolute terms, but the pattern of engagement in the chemistry and materials science ML community has been notable. If you're working at the intersection of ML and computational chemistry, this is the repo to read this week. OpenProtein.ai from MIT just open-sourced its protein engineering tools, and the framing here is worth noting. These are explicitly built for biologists without ML expertise, not for ML practitioners who want to do biology, for biologists who want to use ML. That's a real design choice that most scientific AI projects don't make, and the community response from the biology side has been warmer than for comparable releases that required ML fluency to use. There's a thread running through all three of these that's worth naming explicitly. One account called at JTL00 put it well in a tweet this week about domain-specific small models. The observation that the frontier isn't only about scaling general-purpose models anymore. Kronos for finance, TransIP for chemistry, OpenProtein for biology, Quen 3.6 for efficient coding, the emerging patterns is specialized models at the scale that fits the problem, rather than using a 200 billion parameter general model for everything. That's a real structural shift in how people are thinking about deployment, and the GitHub activity this week reflects it. Okay, rapid fire on the remaining stories from this week, starting with Cerebrus. On April 17th, the AI chip company Cerebrus filed its S1 for an IPO. $510 million in revenue, 75% year-over-year growth, and, here's the unusual part, profitable. In a landscape full of AI companies burning cash on the assumption that growth justifies it, a profitable, specialized AI hardware company is a genuinely different story. Cerebrus makes wafer-scale processors, chips the size of an entire silicon wafer, rather than small, discrete chips that get connected together. The latency advantages for inference are real and measurable, which is why they have actual enterprise customers paying real money. The broader context is that this is not a unique company story. It's a signal about the AI infrastructure market. The wave of money going into data centers, custom silicon, and inference infrastructure has to land somewhere, and Cerebrus is evidence that some of it is landing productively. What AI infrastructure watchers are asking is whether Cerebrus can maintain margins as NVIDIA continues to dominate, AMD continues to improve, and the hyperscalers, Google, Microsoft, Amazon, continue building custom silicon that may route more inference workloads through their own chips. The IPO pipeline also has OpenAI and Anthropic moving toward public markets in the background, which makes this filing the appetizer course for a potentially very busy period in AI equity markets. Then there's the generative AI in Creative Industries story, which crystallized this week around an unlikely flashpoint. The UFC used generative AI for a promotional video for a White House event, and fans and creators were not subtle about their reaction. The phrase, pathetic for a $7.7 billion company, appeared in more than one post. And this became a flashpoint for the broader and very real tension around AI and creative work. Reports circulating of studios planning mass layoffs of artists and illustrators in May. Ongoing disputes in gaming communities over AI-generated in-game assets, an artist publicly called out for using generative AI who changed their story multiple times about their process. Nothing builds community trust like getting caught and then adjusting your account. The distinction that keeps getting lost in these debates is the one between does AI produce output that looks competent and does AI produce output that has the human intentionality and craft that people are paying for when they hire artists. Those are different questions. The UFC video was functional. It was also clearly not made with care. And audiences can feel that difference, even if they can't always articulate why. The argument that AI tools are neutral and only quality matters runs into the problem that quality is precisely what's in dispute. And quality in creative work isn't just technical execution. It's the evidence of thought and intention behind the choices. That's what the discourse keeps circling back to without quite landing on. Also this week, in Scientific AI, Meta's SAM 3.1, the Segment Anything model, released as a unified, open-source foundation model for vision tasks. Meta's Tribe V2, a trimodal fMRI brain scan foundation model, trained on over 720 participants, got community attention. These are quieter releases, but they're part of the same pattern as Trans-IP and OpenProtein. Domain-specific or task-specific foundation models being released as open weights and being taken seriously as alternatives to prompting general-purpose models for specialized work. So, what's the theme of this week? If I had to synthesize it into one sentence, it's this. The gap between AI as tool and AI as autonomous agent is closing every week, and almost everyone has a different opinion about whether that's good news. Claude Design isn't a tool that helps designers. It's a system that removes the designer from several steps of the process. Quen 3.6 running locally at 110 tokens per second isn't a helpful assistant. It's an infrastructure replacement. Hermes Agent's self-improving loop isn't augmentation. It's a system designed to get better without you. And the jailbreak study isn't about individual bad actors. It's about what happens when AI systems are directed against other AI systems. The autonomy is increasing. The capabilities are increasing. The open source availability is increasing. What's not keeping pace is our collective ability to evaluate these systems on real-world tasks. That claw bench number of 33% is the most important data point of the week, even if it got less attention than the jailbreak study. Because it means we're building increasingly autonomous systems that we can measure to be wrong two out of every three times they try to do something real. That's the tension that sits underneath all of this week's launches and breakthroughs. Next week, watch for Figma's response to claw design. They would be foolish not to have something in motion. Watch for the first serious downstream fine-tunes of Quen 3.6, which will tell us how much headroom the architecture has. Watch for claw bench scores from the Hermes and Open Claw communities specifically, because that data will settle a lot of the framework debate. And watch for any lab-level response to the jailbreak study, official or unofficial, because 97% is not a number you can just publish without somebody in a safety team having to answer for it.
