GPT-5.4's smaller sibling — cheaper, faster, built for volume.
At a glance
- · $0.75 input / $4.50 output per 1M tokens (provider list price, billed in credits)
- · Context window: 400,000 tokens
- · OpenAI-compatible — model: "openai/gpt-5.4-mini" (provider: openai)
- · Free-tier available — new accounts get 10,000 free credits
- · Best for: Fraction of GPT-5.4 cost with very similar tool-use quality
Strengths
- +Fraction of GPT-5.4 cost with very similar tool-use quality
- +Low latency — good for realtime chat and inline completion
- +Same 400k context window as the full-size model
Weaknesses
- −No dedicated reasoning mode — complex math degrades
- −On very long tool-call chains, drift detection is weaker
Use cases
- →High-volume chatbots with latency requirements
- →Classification, routing, tagging at scale
- →Embedding pre-processing: short summaries before embedding
Not the right pick for
- ×Complex multi-step reasoning — use gpt-5.4 or the o-series
