Scores 90/100 (rank #16), placing it in the top 95% of all 290 models tracked.
With only a 0-point gap, these models are in the same performance tier. The practical difference in output quality is minimal - your choice should depend on pricing, latency requirements, and specific feature needs.
Choose GPT-5.2 Chat when you need:
- High-volume production workloads where API costs must be minimized
Choose GPT-5.2 Pro when you need:
- Processing long documents or large codebases (400K token context)
- Step-by-step reasoning and chain-of-thought problem solving
GPT-5.2 Chat offers 92% better value per quality point. At 1M tokens/day, you'd spend $236.25/month with GPT-5.2 Chat vs $2835.00/month with GPT-5.2 Pro - a $2598.75 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-5.2 Chat also offers lower per-token costs for high-volume support
Long document analysis
Larger context window (400K tokens) can process longer documents, contracts, and research papers in a single pass
Batch data extraction
