Verdict
When to choose each
Gemini 3.1 Pro Preview
Where it leads
- Accepts audio input
Best for
- Multimodal reasoning and agentic coding evaluations

- Longer responses, up to 1,000,000 vs 65,536 output tokens
- A cached-input rate, $0.10 per 1M tokens
Best for
- Long-horizon coding and knowledge work once it reaches general API access
Watch out for
- The $2 input and $10 output rates are introductory and end on November 30, 2026; from December 1 Google charges $4 and $20 per 1M tokens
- Not on the Gemini API free tier, and explicit context caching is not supported; implicit caching takes 95% off repeated input
- Answers longer than 64K tokens need background execution, and Google advises client timeouts of at least 15 minutes for hard prompts
