Open-source AI makes transparency the default, so no single monolith can dictate access, research, or innovation.
Say no to the black box. That’s how everyone wins.

We’re rolling out changes to make Fable 5’s safeguards for frontier LLM development visible.
Starting this week, flagged requests will visibly fall back to Opus 4.8—the same as our safeguards for cyber and bio. You will see this every time it happens. On the API, any flagged requests will return a reason for their refusal (coming to server-side fallback in the next few days).
We wanted to deploy Fable 5 to our users quickly and safely. Visible safeguards can be probed, so they have to be robust, which takes time to get right. Invisible safeguards can be targeted more narrowly, allowing us to ship quickly with very few false positives. We went with invisible safeguards for this reason—and that was the wrong tradeoff. You should have visibility into the safeguards we have in place, and why. We’re sorry for not getting the balance right.
Making the safeguards visible makes them easier to work around, so keeping them robust to jailbreaks will unfortunately mean more false positives while we improve the classifiers. We're also tuning our bio and cyber classifiers to trigger less often on harmless requests. We know this is frustrating and we’ll do our best to keep this period as short as possible.
If you think a request has been mistakenly flagged: run /feedback in Claude Code, click thumbs-down on the fallback in Claude.ai or Cowork, or file the safeguard appeal form for API requests. Your reports help us tune these classifiers and we appreciate your feedback.

Harbor integration is live with EvoSkill v.1.2.0
Harbor is a framework for evaluating AI agents against containerized benchmark tasks. It gives EvoSkill access to evolve agents against a registry of 190 datasets — including benchmarks like SWE-bench Verified, Terminal-Bench 2.0, and Aider Polyglot.
Here’s what it means for automated agent evolution ↓

skillmaxxing era unlocked.
we built EvoSkill v1 — open-source toolkit that lets AI agents evolve their own skills from failure traces
just give it a benchmark scoring function and let it cook. voilà .

Introducing EvoSkill V1, an open-source toolkit that takes a benchmark and a coding agent, and evolves it into a state-of-the-art specialist in minutes.
Here’s all you need to start evolving, starting with your Claude Code ↓

Introducing EvoSkill V1: an open-source toolkit that evolves any coding agent into a state-of-the-art specialist in minutes.
V1 acts as autoresearch for AI agent skills. Just plug in a benchmark, a ground-truth table (or an LLM judge rubric), and a coding agent, and it evolves the agent against that benchmark.
This is the first production drop from Sentient Labs' AI evolution research, where we're exploring how to make AI self-improve across prompts, skills, memory, and the agent harness itself.

Great first night with Cohort 0 over trivia, with questionable rules, and zero mercy.

We are excited to welcome Arena’s Cohort 0.
We’ll be joined by top-tier builders, researchers, and operators from across the ecosystem who will first face Challenge 0: Grounded Reasoning over Large Corpora.
Our objective is to document Cohort 0 findings and open-source them.
We’re aligned with efforts like GEPA’s Labs and Karpathy's autoresearch that proved that open-sourced research compounds faster, and we are happy to provide the platform to forward open-source AI research and developments.
Looking forward to what Cohort 0 can come up with!
