GPT-5.5 · Model overview
A compact view of reviewed task guides, public evaluations, and evidence boundaries. Client access still depends on your current account.
Model access and permissions must be checked in the current Tabbit account.
Extract structured data, build a visual prototype, or start a coding task.
OpenAI's GPT-5.5 guidance puts the goal, success criteria, allowed side effects, evidence rules, and delivery fields first, then asks the agent to verify the result with targeted checks.
This official configuration guide focuses on Responses API reasoning levels and multi-turn state transfer, with response items preserved across tool calls.
The official model page lists GPT-5.5 snapshots, reasoning parameters, and the Responses API tool surface for an integration baseline.
Public results use different versions, tiers, and harnesses; unknown values stay unknown.
OpenAI's release page attributes GPT-5.5 results in tool-heavy coding, browsing, and cross-software agents to specific harnesses; the tables cannot be reproduced without the snapshot and tools.
Vellum aggregates public GPT-5.5, Claude, and Gemini scores and shows substantial task-to-task variation; it is a cross-source digest, not a controlled rerun.
