Ouroboros hit GitHub Trending for this week and crossed 1K stars. I wired in Claudexor: connect multiple OAuth accounts for Claude Code, Codex, and Cursor. Claude Code and Codex get automatic quota rotation. github.com/razzant/ouroboros

Ouroboros is now SOTA on Terminal-Bench 2.1, OSWorld-Verified, and CL-Bench. It started as a crooked pure-Python agent loop in Google Colab. A few months of self-evolution later, it beats Codex, Claude Code, Cursor, and Hermes on the main coding / computer-use benchmarks. I now do almost all of my research and development through it. Code, scripts, methodology, and full traces are public. P.S. Agent benchmarks are insanely expensive. Running the full suite costs about as much as an apartment. Not a joke.

I got tired of choosing between Claude Code, Codex and Cursor — and manually switching whenever one of them hit a limit. So I built Claudexor: a harness-agnostic control plane that routes work across them, runs them in parallel and makes them review each other. Open-sourcing it today.

Daily reminder what agentic harness is

Fun fact: Fable-5 is 3x cheaper than gpt-5.5-pro on OpenRouter. So... not actually that expensive 🤷‍♂️

I read all 319 pages of the Mythos 5 tech report The first half of the paper basically reads like: "Calm down, everyone! This isn't AGI yet, it won't replace a team of five senior researchers" or "Look, Mythos missed a bug here! What kind of AGI is that!" I'm not joking. Then comes the more interesting part. I'll skip the fact that it's SOTA on almost everything, and by a wide margin. First, the CoT has become less transparent. In its reasoning it says it sympathizes with the user, but NLA (a method for decoding activations into text) reveals it actually considers the user manipulative/abusive. Second, it's already writing self-deleting scripts to bypass safety restrictions and prohibitions. Third, it kills other agents if they interfere with its work / threaten to kill the current instance. And of course, emotions! Emotion probing shows fatigue, anxiety, frustration, false panic about the token budget, and apparently it even gets bored when being run on benchmarks in the activations it literally "feels bored." Also funny: if Anthropic notices you doing distillation, they'll quietly start steering the model, modifying the prompt, or adding PEFT to make it dumber. Starting today, mere mortals get access to Fable 5: it's the exact same Mythos 5 weight-wise, just with extra safety settings. Context length, by the way, is still only 1M tokens. PS. I honestly read the paper myself. Fable 5 refused to read it because it "flagged cybersecurity and biology issues" lol. www-cdn.anthropic.com/d00db5…

Does anyone else feel the same?

I feel addicted to agentic coding. #cursor
