GPT-5.6 Terra has a 10-point advantage, which typically translates to noticeably better performance on complex reasoning, code generation, and multi-step tasks.
Choose GPT-5.4 Nano (batch) when you need:
- High-volume production workloads where API costs must be minimized
- Step-by-step reasoning and chain-of-thought problem solving
Choose GPT-5.6 Terra when you need:
- Processing long documents or large codebases (1050K token context)
- Step-by-step reasoning and chain-of-thought problem solving
GPT-5.4 Nano (batch) offers 92% better value per quality point. At 1M tokens/day, you'd spend $10.88/month with GPT-5.4 Nano (batch) vs $131.25/month with GPT-5.6 Terra - a $120.38 monthly difference.
Both models have comparable response speeds. For most applications, the latency difference is negligible.
When latency matters most: Interactive chatbots, IDE code completion, real-time translation, and user-facing applications where response time directly impacts experience. For batch processing, background summarization, or offline analysis, latency is less critical.
Code generation & review
Based on overall model capabilities and architecture for coding tasks like generating functions, debugging, and refactoring
Customer support chatbot
Suitable for user-facing chat with competitive response times. GPT-5.4 Nano (batch) also offers lower per-token costs for high-volume support
Long document analysis
