GPT-6-Astra appears staged on OpenAI API as 404-vs-400 quirk reveals unreleased model slugs
Angaisb_ · x · 2026-09-03
- The OpenAI Responses API returns 404 Not Found for "gpt-6-astra", while garbage/non-existent slugs return 400s — the same 404 is returned for "5.6 Cyber", a slug known to exist.
- A similar quirk in the Bedrock API surfaced Fable 5.1 a day before its launch, suggesting this pattern indicates a staged model.
- The poster speculates GPT-6-Astra may be the official name, possibly contradicting The Information's report that it wouldn't be called GPT-6.
- Unverified leak — not confirmed by OpenAI.
