Scores 42/100 (rank #230), placing it in the top 21% of all 290 models tracked.
Scores 40/100 (rank #232), placing it in the top 20% of all 290 models tracked.
With only a 2-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-4.1 Nano when you need:
- High-volume production workloads where API costs must be minimized
Choose GPT-6 Astra when you need:
- Step-by-step reasoning and chain-of-thought problem solving
GPT-4.1 Nano offers 99% better value per quality point. At 1M tokens/day, you'd spend $7.50/month with GPT-4.1 Nano vs $900.00/month with GPT-6 Astra - a $892.50 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-4.1 Nano also offers lower per-token costs for high-volume support
Long document analysis
