GPT-5.4 vs o1
Pricing, benchmarks, and use case comparison
Quick take
- •GPT-5.4 is meaningfully stronger at cost efficiency (72 vs 35 on our capability index).
- •GPT-5.4 is 83% cheaper on input tokens, which compounds fast on high-volume or agentic workloads.
- •o1 has a 200,000 tokens (100,000 max output) context window vs 1,050,000 tokens (128,000 max output) - better for whole-repo or long-document work.

Which should you choose?
Choose GPT-5.4 if...
- →Large-context tasks where GPT-5.5-level frontier reasoning is not required
- →Cost-conscious production workloads that still need strong capability
- →Migrating from GPT-5.4-based systems where behavior is already tuned
Choose o1 if...
- →Hard, multi-step math, science, and logic problems that reward deliberate reasoning
- →Competitive programming and algorithmic problem solving
- →Existing o1-based pipelines already validated for reasoning tasks
