OpenAI increased GPT-6.1 Sol’s default context window in Codex and ChatGPT Work from 272K to 500K tokens. Users can configure up to 1 million tokens, reducing compaction during long coding and professional-work sessions.
Users reportedly saw Claude Opus 5.5 route to a stronger, unreleased checkpoint during demanding coding, 3D, and system-building tasks. The demonstrations suggest backend testing or canary routing, but Anthropic has not confirmed the behavior.
StepFun’s Step 5 Preview is now available inside Tencent’s WorkBuddy, with exclusive free access from October 12 through October 25. The 600B-total, 27B-active sparse MoE model supports a 1M-token context window and text-plus-vision input, with open weights promised for October 15.
