We are giving all Codex users a usage reset on the house. Should be showing in your accounts in the next few hours.
We have applied some mitigations, but our investigation hasn't shown users being impacted at large. We are continuing to monitor the situation.
Since June 12, we’ve been working closely with the US government to restore access to Claude Mythos 5 and Fable 5. Today, the government notified us that Mythos 5, our strongest cybersecurity model, can be redeployed to a set of US organizations that operate and defend critical infrastructure.
We’re restoring access for these organizations quickly, and we’re continuing to work with the government to expand access to Mythos 5 and make Fable 5 available for general use again.
We have a new version of GPT-5.5 Instant for you, and it's much more fun to talk to.
Our most-used model is now better at understanding the intent behind a question and adapting its response accordingly.
It also handles complex constraints more reliably and makes shopping and local recommendations more useful and cohesive.
Rolling out today to paid users, tomorrow to free users.

We heard you wanted to use Codex rate limit resets on your own time.
Starting today, we’re rolling out the ability to save rate limit resets to use later.
We’re starting Go, Plus, Pro, and Business users with one free reset:
Gemma 4 now runs 2x faster with MTP GGUFs! Run locally on just 6GB RAM. ⚡️
MTP enables Google Gemma 4 run ~1.4–2.2× faster with no accuracy loss.
Gemma 4 12B MTP can run at 162 t/s vs. 52 t/s without MTP. 31B reaches 101 t/s.

Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.
Its capabilities exceed those of any model we’ve ever made generally available.

We’re introducing a new GitHub Certified: Agentic AI Developer (GH-600).
As AI agents become part of modern development workflows, this role-based certification focuses on how developers and teams operate, supervise, and integrate agents across the SDLC.
If you’re already working with tools like GitHub Copilot or exploring agent-driven workflows, we’d love your input.
