GPT-5.4 — OpenAI's frontier model — to its lineup. It currently leads all other models on Cursor's internal benchmarks. The model carries a 272k context window with 1M token Max Mode support and Agent + Thinking capabilities. Cursor describes it as confident and decisive: it works through ambiguous problems without second-guessing and maintains momentum across long workflows.For developers running heavy agentic coding sessions, this means the most intelligent model in Cursor's lineup also handles parallelism and sustained momentum well — traits that matter more as sessions grow longer and more complex. For cost-sensitive work, Cursor positions GPT-5.3 Codex as a lower-cost alternative where raw intelligence isn't the priority.
To try it, open Cursor's model selector and switch to GPT-5.4. It draws from the API pool at $2.5/M input and $15/M output. A faster variant, gpt-5.4-fast, runs 15% faster at 2x the standard price.
