GPT-5.4
GPT-5.4 is OpenAI's most capable model to date. It outperforms all other models on our internal benchmarks. For cost-sensitive workflows where raw intelligence matters less, GPT-5.3 Codex remains a strong option at a lower price point.
Strengths
- GPT-5.4 is the leading model on our internal evals.
- Confident and decisive. It works through messy, ambiguous problems without second-guessing and stays proactive about next steps.
- Strong at parallelizing work and maintaining momentum across long workflows.
Limitations
- Higher per-token cost than Codex 5.3. If cost per unit of work matters more than peak intelligence, Codex 5.3 may still be the better fit.
- Output can read as more sprawling depending on taste. It favors thoroughness over brevity.
- New model; early feedback and taste tests are still developing.
Tools
GPT-5.4 has access to all agent tools when used with Cursor including:
Find files by name, read directory structures, and grep for patterns.
Generate search queries and fetch results from the web.
Read file contents, including images for vision-capable models.
Suggest edits and apply them automatically.
Execute terminal commands and monitor output.
Control a browser to take screenshots, test applications, and verify visual changes. See the Browser documentation.
Generate images from text descriptions or reference images.
Ask clarifying questions while continuing to work in the background.
Retrieve rules based on type and description.

Pricing
Cursor plans include two usage pools. GPT-5.4 draws from the third-party Other Models pool, which charges at the rates below. Individual plans include at least $20 of third-party Other Models usage each month (more on higher tiers). All prices are per million tokens.

A Fast mode variant (gpt-5.4-fast) is available for priority processing. It runs 15% faster at 2x the standard price. When input exceeds 272k tokens (long context), input pricing doubles and output pricing is 1.5x the standard rate.
