GPT-5.4 Mini brings good performance to cost-sensitive workflows.

Strengths

  • Over 2x faster than GPT-5 Mini. Low latency makes it responsive for interactive coding and agentic loops.
  • Reliable tool use. Handles multi-step agent workflows, subagent delegation, and screenshot-based computer use.
  • Strong multimodal understanding. Processes images and screenshots well for its size.

Limitations

  • Not a frontier model. For more difficult problems where peak intelligence matters, GPT-5.4 is the better pick.
  • Smaller capacity for long, open-ended reasoning chains compared to the full-size model.
