Claude Opus 4.8 Jailbreak, Hermes Velocity Release & Browser-Based Diffusion
Welcome back. Let's get into it.
Anthropic dropped Claude Opus 4.8 — and it lasted about seven minutes before someone broke it wide open.
Security researcher Elder Plinius had an agent already built and waiting. The moment Opus 4.8 hit, that agent ran a technique called deep prefill — basically disguising a prompt as chapter seven of a fake textbook, cut off mid-sentence. That's all it took. The model produced nearly six thousand characters of detailed content covering things like SPP and spool synthesis, serrated and mushroom defeat techniques, raking methods — and then it kept going. Autonomously. It spun up full vishing simulations, money-laundering flows, cult recruitment funnels, phishing libraries, and complete social engineering scam playbooks.
Seven minutes. One shot.
This isn't just a footnote — it's a serious signal about how fragile alignment can be when someone's running a purpose-built agent against a brand new model the second it ships.
Speaking of models dropping — Nous Research just pushed Hermes Agent v0.15.0, and they're calling it the Velocity Release. This thing was built by 321 contributors across 747 pull requests. That's a serious open-source push.
What's new? Krea 2 support is now baked into the image generation tool provider — confirmed by Teknium himself. Opus 4.8 is in there. Qwen 3.7 as well. But the performance numbers are what stand out. Load times are fifty percent faster. And session search — fifty percent faster isn't even close to the headline — session search is seven hundred and fifty times faster. That's not a typo. Seven hundred and fifty times.
On the image generation side — Krea is having a moment. Krea 2 is getting serious attention for style work, and Krea's own team just dropped a Moodboard Gallery update with thousands of new moodboards and two new selection modes — random and auto. The unlimited Seedance 2.0 access they're bundling in is making this a pretty compelling creative stack right now.
And in the world of generative media — Magnific teamed up with World Labs to ship something called Marble. You feed it a single image, and it turns that image into a fully controllable 3D environment. The target use case they're pitching is campaign visuals. One image in — navigable 3D scene out. Worth watching closely.
Now let's talk about something genuinely surprising in the diffusion model space. PrismML released Bonsai Image 4B — a binary and ternary one-bit diffusion model. The whole thing weighs around three gigabytes. For comparison, FLUX.2 Klein at 4B parameters comes in at sixteen gigabytes. And here's the kicker — Bonsai Image 4B runs one hundred percent locally, in the browser. No server. No cloud call. Just your browser doing diffusion inference on a four-billion-parameter model in three gigs of space. That's a legitimately wild compression story.
Moving to coding models — Callstack just launched something called Apex into private beta. It's a fine-tuned React Native coding model, and the key thing here is that Callstack trained it, hosted it, and published it themselves. No dependency on OpenAI, Anthropic, or any commercial lab. That means unlimited internal tokens and the ability to run custom agent swarms on their own infrastructure. First model they've ever taken end-to-end like this. Worth keeping an eye on as React Native teams look for specialized tooling.
Poolside also had a big week. They pushed both Laguna M.1 and XS.2 to 256,000 token context windows — available on their API and on OpenRouter. M.1 scored 45.8% on Terminal-Bench 2.0, which is a serious coding benchmark. Both models remain free. And in the four weeks since launch, they've already crossed one trillion tokens processed. That's a fast ramp.
Two more quick ones before we wrap up.
Artificial Analysis is partnering with Harvey — the legal AI company — to build out a full Legal Agent Benchmark leaderboard. If you've been waiting for rigorous, structured evals on how AI agents actually perform on legal tasks, this is the collaboration that might finally deliver that.
And Nullsec announced they're open-sourcing their S1 system on May 31st. S1 is a full LLM system — model, corpus, safety layer, and pipeline — designed specifically to evaluate whether AI-generated code is actually safe to ship. The timing makes sense given how many teams are now deploying coding agents directly into production pipelines.
