> OpenAI released GPT-5.4 on March 5 with native computer use, tool search and up to 1M context. It reported 75.0% on OSWorld-Verified against a 72.4% human baseline; these are vendor research results, not a general productivity guarantee.

**Correction / update, October 14, 2026:** Removed unverified historical Arena scores and later mini/nano launch context. The computer-use result is OpenAI’s OSWorld-Verified evaluation.

OpenAI positioned GPT-5.4 around agentic computer use, configurable reasoning effort, tool search and long context. Its release evaluations do not establish a historical Arena preference ranking.

**OpenAI** unveiled **GPT-5.4** (March 5) with Pro as its most capable model family for agent-style professional work: native computer-use APIs; configurable **reasoning effort**; context up to **1M** tokens; coding/reasoning gains; **Tool Search** for dynamic tool calling; ChatGPT + API + Codex. Company materials: ~**75%** on **OSWorld** (slightly above human baseline **72.4%**); strong SWE-bench-class coding. Resource shift toward developer and agent tools.

## Claims vs checks

Launch features are **OpenAI primary**. OSWorld/SWE figures are **vendor** (effort settings matter).

## Limits

- Computer-use success rates transfer unevenly outside eval harnesses.
- 1M context availability/pricing varies by SKU.
- Codex 1M-context support was experimental at launch.
