Overview
GPT-5.4 nano is OpenAI's cheapest and smallest current model, built for high-volume, simple, latency-sensitive tasks. It is ideal as a router target for classification, extraction, and lightweight generation where cost dominates. It is not meant for complex reasoning or agentic coding.
Strengths
- Cheapest model in the lineup ($0.20/$1.25)
- Very fast, low-latency output
- 400K-token context despite tiny size
- Multimodal text, image, and PDF input
- Aggressive cache discount for repeated prompts
Trade-offs
- Limited reasoning and coding depth
- Not for complex or agentic tasks
- Weaker instruction adherence on hard prompts
Fit
Best for
- High-volume classification and extraction
- Routing and intent detection
- Cheap autocomplete and suggestions
- Bulk tagging and moderation
- Latency-critical lightweight calls
Not ideal for
- Complex reasoning or coding
- Agentic work
- High-quality long-form writing
