Developers spotted a "gpt-5.6" routing string tied to codename iris-alpha, a reported 1.5M-token window (~43% over GPT-5.5), and cleaner one-shot UI generation, per TokenMix. OpenAI has announced nothing, and Polymarket prices roughly 80-89% odds of a release by June 30. Treat this as a rumor with an indirect evidence trail, not a launch. Worth noting only because it's the dominant speculation this week and a 1.5M context would matter for the long-horizon agent work everything else today is about.

The claim covers selected attention and MoE blocks, alongside a claim that model-assisted kernel work brought three previously unplanned open-weight models to high performance on the new chip in about two months (Latent Space). Treat the numbers as first-party until the full H...
Two thirds. Not two thirds of a contrived jailbreak set. Two thirds of realistic malicious issue requests, against the exact three tools most of the people reading this run daily. Ankur Singh, Jinqiu Yang, and Tse-Hsun Chen built IssueTrojanBench across four attack categories...
OpenAI released GPT-5.4 simultaneously across ChatGPT, API, and Codex — the first unified triple release. Built-in computer-use capabilities (build-run-verify-fix loop), 1.05M token context, and 33% fewer false claims vs GPT-5.2. A new experimental "Playwright Interactive" ski...
The July 18 release notes bundle fixes that restore the full window, which means it had been silently degraded for some unspecified period. If you benchmarked those models in Codex over the past few weeks and found long-context performance underwhelming, you may have been meas...
Spotify's Portal team published Xirp on August 10: a vendor-neutral agentic development environment that manages concurrent sessions across Claude Code, Gemini CLI, and Codex, each session isolated in its own git worktree so dozens of agents can work the same codebase without...
If you have a CLAUDE.md, you're in scope. Today. arXiv 2607.14611 (cs.CR, filed July 16) evaluates prompt injection planted in the persistent memory files that agentic coding systems write and re-read across sessions. The researchers tested both Anthropic's Claude Code and Ope...
