> OpenAI GPT-5.4 Pro (March 5): high-end of the 5.4 family for complex multi-step reasoning, coding, long-context tool chains — ChatGPT Pro/Enterprise and API `gpt-5.4-pro`. Quality-over-speed/cost SKU on the same agentic/computer-use base as standard 5.4; Thinking on Plus/Team/Pro, Pro model gated higher.

Tiering is the business model. GPT-5.4 Pro’s proprietary frame: **same agentic substrate as 5.4, sold as the quality-max SKU** for users who will pay latency and dollars for hard multi-step professional work.

**OpenAI** introduced **GPT-5.4 Pro** alongside the GPT-5.4 family (March 5): stronger results on complex coding, research, and decision-making; better very-long-context and intricate tool-use chains; configurable for quality over speed/cost. Available to **Pro and Enterprise** ChatGPT plans and via API as **`gpt-5.4-pro`**. Rollout: GPT-5.4 Thinking to Plus/Team/Pro; Pro model limited to higher plans; both live in API. Builds on agentic and computer-use foundations of base GPT-5.4; family also emphasizes efficiency improvements alongside capability jumps.

## Claims vs checks

SKU availability and positioning are **OpenAI primary**. “Top performance” deltas vs standard 5.4 are vendor-framed — use the main 5.4 article for OSWorld/Arena numbers; Pro-specific independent Elo splits were not separately frozen here. Early developer/enterprise feedback is anecdotal.

## Limits

- Pro gating means most Free/Go users never see this SKU.
- Quality-max still fails on some tool chains; auditability remains on the user.
- Pricing/rate limits change; check live API docs.
