GPT-5.4 Nano
GPT-5.4 Nano is the smallest and fastest model in the GPT-5.4 family. At $0.20 per million input tokens, it's built for high-volume workloads where speed and cost matter more than peak reasoning. Reach for it when you need quick classification, extraction, ranking, or lightweight coding support.
Strengths
- Fastest model in the GPT-5.4 lineup. Ideal for latency-sensitive tasks and tight agentic loops.
- $0.20/1M input tokens. One of the cheapest options available. Strong for high-volume pipelines and subagent work.
- Good at structured tasks. Classification, extraction, ranking, and simple code edits land reliably.
- Supports tool use. Can drive agent workflows, though best paired with a larger planning model for complex multi-step work.
Limitations
- Not designed for deep reasoning or large-scale code generation. Stick with GPT-5.4 Mini or GPT-5.4 for harder problems.
- Trades capability for speed. Expect lower quality on open-ended or ambiguous tasks.
Tools
GPT-5.4 Nano 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.
