# GPT-5.4: Agentic Computer Use Is the Product, Not Chat Elo

> OpenAI GPT-5.4 (March 5) — Thinking/Pro with mini/nano following: native computer use, configurable reasoning effort, up to 1M context, Tool Search. Lab OSWorld ~75% (above human 72.4% baseline in OpenAI materials). Early Arena snapshots ~1502 Elo briefly over Opus 4.6 (~1494) — snapshot-sensitive; durable story is agents + computer use.

Frontier launches still get ranked on preference Elo. GPT-5.4’s proprietary frame: **ship the agentic computer-use stack** — configurable effort, Tool Search, long context — and treat early Arena leads as **snapshot weather**.

**OpenAI** unveiled **GPT-5.4** (March 5) with Pro and (days later) mini/nano variants 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.

| Source | Snapshot | Standing |
|--------|----------|----------|
| **LMArena / Arena Text** | March 2026 boards | Secondary coverage: GPT-5.4 near **~1502 Elo**, briefly above Claude Opus 4.6 (**~1494**) on some preference snapshots |
| **Vendor OSWorld** | Launch materials | ~**75%** vs human **72.4%** baseline |

Label early Arena leads as **snapshot-sensitive**; 5.4’s durable story is **agentic computer use + pricing tiering**, not permanent #1 preference.

## Claims vs checks

Launch features are **OpenAI primary**. OSWorld/SWE figures are **vendor** (effort settings matter). Arena Elo is **independent preference board** but volatile week-to-week.

## Limits

- Computer-use success rates transfer unevenly outside eval harnesses.
- 1M context availability/pricing varies by SKU.
- Mini/nano economics belong in the March 17–18 files.
