Capability profile
cost efficiency weak
Operator guidance
Backfilled 2026-07-11 alongside the GPT-5.6 launch entries; no independent routing signal beyond price is available yet. Treat as OpenAI's premium ceiling tier until a dedicated model card is found.
Use cases
- OpenAI's highest-priced tier — positioning beyond price is not independently confirmed (see limitations)
Limitations
- This model does not appear on OpenAI's models documentation page (developers.openai.com/api/docs/models) as of 2026-07-11 — only the pricing page lists it. Knowledge cutoff, supported tools, and every capability dimension besides cost-efficiency are omitted rather than guessed or carried over from gpt-5.5's own doc, since no primary source confirms they're shared. context_window is the one exception -- confirmed 2026-07-12 via the pricing page's raw embedded JSON payload, which labels the row "gpt-5.5-pro (<272K context length)".
- Capability ratings are qualitative, not a single cited benchmark run
