GPT-5.4 lands for pro workflows

OpenAI says GPT-5.4 is its most capable frontier model for complex professional work, blending stronger reasoning, coding, and agentic workflows in one release. The API docs list a 1.05M-token context window, 128K max output, and premium $2.50/$15 per 1M input/output pricing.

// ANALYSIS

GPT-5.4 looks less like a mass-market refresh and more like OpenAI's premium serious-work tier for teams willing to pay for bigger context, deeper tool use, and stronger coding performance.

–Vals' March 5 benchmark listings already show GPT-5.4 on top in IOI, ProofBench, and Vibe Code Bench v1.1, which reinforces OpenAI's professional-work positioning
–The 1.05M-token window targets large repos, long briefs, and multi-step agent runs where context fragmentation becomes a real productivity tax
–OpenAI exposes the full tool stack here — web search, MCP, code interpreter, hosted shell, apply patch, and computer use — signaling that agent workflows are a first-class use case
–Pricing is the catch: at $15 per 1M output tokens, GPT-5.4 looks built for high-value coding and research tasks, not cheap bulk generation
