Token Gremlin Claims OpenAI Is Quietly Testing GPT 6.2 Astra, With the Model Name Showing Up in Codex Usage Data
OpenAI is quietly A/B testing a new variant called GPT-6.2 Astra, and it's already showing up in Codex usage analytics. The model picker still says GPT-6 Astra, but the usage breakdown for some accounts now lists gpt-6.2-astra separately. Multiple users are seeing the exact same thing, so this isn't a glitch. It's a gray rollout, and a new Astra is coming soon.
Context
An unannounced upgrade to OpenAI's Astra model would change what Codex users get without notice, but the claim rests on user screenshots and OpenAI has not confirmed it.
Token Gremlin is an X account that tracks AI model usage and pricing. GPT 6 Astra is the OpenAI model currently offered in Codex, OpenAI's coding agent. The claim of a GPT 6.2 Astra test is unverified and OpenAI has not announced the model. Chubby (@kimmonismus) amplified the report and later wrote that GPT 6.2 is very close.
Deep dive
Token Gremlin, an X account that follows AI model usage, claimed on Nov 1 that OpenAI is quietly A/B testing a new model variant called GPT 6.2 Astra. This is unverified. OpenAI has not announced a GPT 6.2 model or commented on the post.
According to the post, the Codex model picker still shows GPT 6 Astra, but the usage breakdown for some accounts lists GPT 6.2 Astra as a separate entry. Token Gremlin says multiple users are seeing the same thing and calls it a gray rollout, meaning a gradual test with a share of users. The attached chart shows one account's usage split as 80 percent GPT 6 Astra, 19.8 percent GPT 6.2 Astra and under 0.1 percent GPT 6 Luna. The post does not say whose account the chart comes from.
Chubby (@kimmonismus) quoted the report and later posted "Confirmed. GPT-6.2 very close," without naming a source. That post drew close to 80,000 views. Later in the day Chubby said he was seeing more posts from users who report GPT 6.2 Astra already rolled out in the Codex command line tool, and said he expects a release on Monday or Tuesday. Those are also his own expectations, not OpenAI statements.
The report came on the same day as an unverified leak about Anthropic's Claude Mythos 5.5, adding to talk that both labs are preparing new frontier models.
What to expect next
Watch for an OpenAI announcement or release notes for Codex naming GPT 6.2 Astra, and for more users reporting the model in their usage data or in the Codex command line tool. If it ships, the open questions are what changes against GPT 6 Astra, whether it reaches ChatGPT as well as Codex, and how it compares with Anthropic's next model. Chubby's expected Monday or Tuesday release is his prediction only.
