Why teams are evaluating GPT-5.5
Source-backed capabilities from OpenAI’s official release
Available Across ChatGPT, API, and Codex
OpenAI launched GPT-5.5 and GPT-5.5 Pro for ChatGPT and API workflows, with stronger coding, computer use, and deep research capabilities.
Native Computer Use
OpenAI describes GPT-5.5 as its first general-purpose model with native computer-use capabilities for multi-app workflows.
Tool Search for Lower Token Overhead
Instead of preloading all tools into context, GPT-5.5 can look up tool definitions on demand. OpenAI reports up to 47% token reduction in testing.
Reasoning + Mid-Response Course Correction
Thinking mode can present an upfront plan and supports user guidance while responses are in progress for more controllable execution.
1M Token Context (Codex, Experimental)
GPT-5.5 supports up to 1M tokens in Codex experimental settings for large-scale repositories and long technical contexts.
Frontier Benchmark Results
OpenAI reports 83.0% on GDPval and 75.0% on OSWorld-Verified, positioning GPT-5.5 for high-stakes professional tasks.
