GPT-6.2 'Astra': From Rumors to API Codename Clues

Multiple leakers spotted a疑似 GPT-6.2, codenamed 'Astra', in OpenAI's Codex usage data in early November. Days later, rc-ada model codenames briefly appeared in the API, adding evidence to the quiet rollout rumors.

Episode 1 · GPT-6.2 Astra surfaces in Codex usage data, OpenAI apparently gray-testing next flagship (2026-11-01, 17 posts)

Starting Nov 1, multiple bloggers nearly simultaneously reported that OpenAI is about to release GPT-6.2, internally codenamed "Astra." Independent sources observed the model identifier in Codex usage panels, API responses, and the CLI, with some accounts seeing nearly 20% of requests routed to the new model and one account as high as 98.5%. The converging evidence strongly suggests pre-release gray/shadow testing, but OpenAI has made no official confirmation and the release timing remains rumor.

Confirmed

  • Multiple independent sources spotted a "gpt-6.2-astra" entry in Codex API usage breakdowns: the model selector UI still shows GPT-6 Astra, but some accounts' usage breakdowns list gpt-6.2-astra separately (m2, m8, m11, m16).机器之心 noted identical screenshots across many accounts, suggesting broad gray-testing rather than a display glitch, though the official model catalog does not yet list it (m16).
  • User idg23's data: gpt-6.2-astra accounted for 18.3% of usage over a week, versus 79.3% for gpt-6-astra (m12); 新智元 reported developers' packet captures showing the new model absorbing 19.8% of real traffic in billing (m15); 量子位 reported some users (mostly $500 Pro plans) seeing it in their model lists, with 20% of requests routed to 6.2, and some users 100% (m17).
  • A Reddit-shared screenshot shows X user Sad AlbertX's usage history with gpt-6.2-astra at 98.5%, claiming use since Nov 1 (m9).
  • kimmonismus and markk both posted API response JSON screenshots with model field "gpt-6.2-astra" (m1, m3).
  • A Reddit user found the Codex CLI accepts codex --model gpt-6.2-astra; requests error out but the name is accepted, suggesting backend readiness (m11); however blogger Angaisb tested it and found it not usable (m7).
  • idg23 also found an unpublished entry in the Japan-region usage panel: a model named gpt-6-astra took 97.6% of usage over 7 days (gpt-6.1-sol 1.1%, gpt-5.6-terra 1%, etc.) before being rolled back, further evidence of shadow testing (m14).
  • 新智元 reported the Codex underlying model was quietly switched to gpt-6.2-astra, with background on the originally planned October 6.1 release (m15); 量子位 documented the buzz around unreleased models from both OpenAI and Anthropic surfacing (m17).

Unconfirmed

  • Screenshot authenticity is unverified by OpenAI; similar Reddit leaks are also unconfirmed rumors (m8, m9, m10).
  • imjustnewatai also claimed GPT-6.2 Astra launches next week, but the poster admits prior trolling, so credibility is doubtful (m6).
  • markk claimed GPT-6.2 could be announced as early as Monday, possibly as the finale of OpenAI's "28 Days of Improvements"—speculation (m3); koltregaskes also judged a next-week release likely (m13); 机器之心 mentioned the "skipping 6.1 or direct release" theory (m16).
  • haider1 offered two guesses on "Astra 6.2": a larger, stronger model possibly the shelved "Bel," or a regular iteration of the astra/sol/terra series (m4). He also argued the dense 28-day run of Codex upgrades (larger context windows, stronger subagents, more generous usage) may be part of a launch strategy targeting Anthropic's 5.5 lineup (m5)—blogger opinion.
  • kimmonismus suggested the new model may be a flagship response to competitor Fable 5.5—blogger opinion (m1).

Why it matters

  • Real model identifiers in usage panels, CLI acceptance of the model name, and the rolled-back 97.6% gpt-6-astra entry mutually corroborate that the product is in pre-release testing rather than mere rumor—the strongest evidence in this cluster.
  • If GPT-6.2 is real, it will reshape OpenAI's flagship lineup and competitor timing; 新智元 juxtaposed its leak with Claude Mythos 5.5's same-weekend leak, arguing the next flagship race has started early (m15), warranting close watch on official follow-ups.

Episode 2 · OpenAI API briefly lists rc-ada model IDs, fueling GPT-6.2 Astra rumors (2026-11-04, 7 posts)

On November 4, multiple users and third-party model trackers discovered two previously unannounced model identifiers in the OpenAI API—rc-ada-or-vm and rc-ada-sh-vm. The identifiers were reportedly added and quickly removed, sparking speculation that OpenAI is about to release new models.

Confirmed

  • Model trackers (the Models Tracker bot and the "New OpenAI Models" panel from third-party account zAI) captured the two new identifiers under OpenAI's name, with screenshots from multiple sources corroborating each other.
  • As of publication, OpenAI has not issued any statement about the two identifiers.

Unconfirmed

  • The purpose, capabilities, and positioning of the two models are unknown; some believe the naming pattern suggests internal testing or the precursor to a new model family.
  • Leaks claiming "gpt-6.2 astra loading" and "GPT-6.2 Astra is coming" predict an official debut within the week, with some users guessing a launch as soon as tonight—but none of this is officially confirmed.

Why it's relevant

  • The "rc-" prefix typically stands for release candidate; if that reading holds, the new model has entered its final pre-release stage—a strong launch signal.
  • Such API identifier leaks often precede OpenAI product launches and can serve as clues for tracking its model roadmap, but should be treated as rumors until officially confirmed.
