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

Capabilities

Ten axes, normalized 0–100 and scored the same way across the whole catalog — so a 78 here means what a 78 means anywhere else on the bench.
