OpenAI's next "GPT-OSS" release date

Prediction market on manifold. This market refers to OpenAI's next open-weight model release, regardless of what it is ultimately named. Minor naming changes from the working name 'GPT-OSS' will count. The model must be accessible without individual vetting or invitation — free or paid, via API or product. Open, non-selective waitlists count. Closed betas, invite-only access, researcher programs, A/B tests, and anonymous benchmark appearances do not. Country-level bans do not prevent resolution.
