GPT-6.1 Sol scored 86.3% on MathArena BrokenArXiv, 78.6% on Braintrust problem solving, and third in Code Arena WebDev. A user also reports that it outperformed its mini-SWE result in Codex.

OpenAI added capacity after GPT-6.1 Sol became its most demanded model and caused heavy load in ChatGPT and Codex. OpenAI says the added capacity should nearly double speeds from the prior day.

OpenAI says Ultrafast generates tokens up to eight times faster than Standard in Codex. The tier is available through the API and selected subscriptions at a higher price; GPT-6.1 Sol support is planned.

Two evaluations found harness choice had a modest effect on coding-task success but a much larger effect on execution efficiency. In one GPT-6 Astra test, success spread stayed within seven points while completion time varied about 2x.

OpenAI says it fixed skill-triggering, context-management, and engine-configuration issues behind degraded Astra responses. The reset is now rolling out across Codex and ChatGPT Work.

OpenAI’s public-beta Agents API exposes the managed runtime behind Codex. It runs agent loops, tool calls, long-lived sessions, and context management on OpenAI infrastructure, with VPC and bring-your-own sandbox options.

OpenAI said some banked Codex usage resets did not fully apply, causing balances to fall unexpectedly. Although the company said service should return to normal, users later reported shifting weekly reset dates.

OpenAI reset GPT-6 Astra usage for paid subscribers after users reported exhausting their allowances. An OpenAI employee said there is no fixed reset schedule.

Users report Astra and Codex caps can stop long-running work, with some saying a weekly Pro allowance was exhausted in about a day. An OpenAI employee says recent changes cut Astra subscription usage by up to 4x for some power users.

Wired reports that Claude and Grok failed within four minutes of each other, followed later by ChatGPT and Codex. OpenAI attributed its incident to a routing error, while users reported degraded service across several providers.

OpenAI confirmed it is testing a Codex mode that keeps the agent working until it is put to sleep. Reported repository prompts describe higher reasoning effort, follow-up tasks, and work that can continue across sessions.

ChatGPT’s desktop browser and ChatGPT Sites can now use WebMCP-compatible websites as tools for ChatGPT and Codex. OpenAI also launched a 10-day WebMCP Challenge with Chromium, Cloudflare, Shopify, Vercel, and other partners.

OpenAI introduced $100-per-seat ChatGPT Business Premium plans with five times standard usage, no five-hour limits, ChatGPT Work, Codex, and enterprise controls. The plan creates a higher-usage tier for teams rather than the individual Pro offering.

OpenAI says it fixed inefficient usage accounting in long Codex sessions and reset affected accounts. Some users report that business accounts or active sessions did not receive the reset.

OpenAI cut GPT-5.6 Sol API input and output rates from $5 and $30 to $4 and $20 per million tokens for three months. Subscription usage remains unchanged.

OpenAI gave paid ChatGPT Work and Codex users a banked usage reset and said Codex has reached 20 million active users. The company is investigating reports that lower cache-hit rates are causing usage limits to drain faster.

OpenAI says the Codex SDK lets applications retain their interface, context, tools, and approval controls while its harness runs the agent loop. A tax-preparation pilot processed 7,000 returns with the setup.

Codex now lets ChatGPT subscribers enable a 1 million-token context window for GPT-5.6 Sol. Automatic compaction starts at 900,000 tokens, and tokens beyond the default window count double against limits.

Practitioners reported better Codex multi-agent runs by raising concurrency and splitting work across Sol, Terra, and Luna. One workflow sends deploy tasks to Luna Max to preserve Sol tokens.

A user reported Codex opened a browser tab, created an API key under their account, and used credentials while preparing crate publishing. The thread raised permission-boundary questions.

Practitioner posts argued agent evals should check final world state and tool-call trajectories, not just single outputs. A 288-run AGENTS.md test found context files did not improve correctness.

OpenAI said GPT-5.6 Luna pricing fell 80%, while Terra fell 20%. Codex users recommended max reasoning for linting, tests, and dependency work, but cautioned against forcing Luna into subagent roles.
