MirrorCode benchmarks Claude Opus 4.6 on a 16,000-line software reimplementation
Epoch AI and METR introduced MirrorCode, a long-horizon benchmark where models reimplement software from execution-only access; Opus 4.6 completed a 16,000-line bioinformatics toolkit. The authors say oracle tests and memorization risks still limit how directly the result maps to everyday software work.


Claude Code launches /ultraplan preview with web planning and cloud execution
Anthropic launched /ultraplan, moving Claude Code planning into a web review flow with cloud execution or terminal handoff. Claude Code 2.1.101 also adds OS certificate-store trust by default, a command-injection fix, and new prompt rules for browser validation and prompt caching.

GLM-5.1 ranks #3 on Code Arena
Arena ranked GLM-5.1 third on Code Arena and first among open models, putting it on par with Claude Sonnet 4.6 and within about 20 points of the overall lead. The update gives the open model a new frontier coding benchmark after its initial release and hosting wave.

OpenAI rotates macOS app certificates after Axios signing workflow risk
OpenAI said a compromised third-party developer tool affected its macOS app-signing workflow and is rotating certificates for ChatGPT Desktop, the Codex app, Codex CLI, and Atlas. The company said it found no evidence of user-data access or software tampering, and older macOS app versions will stop working after the update window.
