Anthropic and OpenAI may be testing Fable 5.5 and GPT-6.2 Astra
Leaked data suggests Anthropic and OpenAI are preparing their next-generation models simultaneously. A catalog entry for "Fable 5.5" appeared on Anthropic's platform on October 13, 2026, but was removed by the following day. Separately, usage logs for OpenAI's Codex product showed a reference to "2-astra" on November 1, 2026, which aligns with the naming convention of its current flagship, GPT-6…
Key points
- Anthropic's Fable 5.5 catalog entry appeared on October 13, 2026, and was removed the next day.
- OpenAI's Codex logs showed a "2-astra" reference on November 1, 2026, hinting at GPT-6.2 Astra.
- Anthropic reported Q3 2026 revenue of $17.0 billion and $96 billion in cash in its S-1 filing.
The timing of these potential leaks coincides with significant corporate milestones. Anthropic is currently in an IPO process, with its roadshow set to begin no earlier than November 10, 2026. The company recently amended its S-1 filing for a Nasdaq listing, reporting third-quarter revenue of $17.0 billion and holding $96 billion in cash. Analysts suggest Anthropic may be delaying a public announcement to avoid the appearance of marketing to investors during its listing process.
OpenAI released GPT-6 Astra on September 3, 2026, priced at $10 per million input tokens and $50 per million output tokens. Any future release of GPT-6.2 Astra will be judged against this pricing benchmark. Until independent testers can access the rumored models, their capabilities remain unverified, leaving the industry to speculate based on deleted listings and internal log strings.
