MiniMax M3.1 Flash ranks higher on the ModelCap Index as of 23 October 2026: #22 against #34. That is a capability ranking built from public benchmark evidence with published uncertainty; whether it is "better" for you also depends on price, context and where you can run it. Their published uncertainty intervals overlap, so the rank difference alone does not establish a reliable capability advantage for your workload.
MiniMax M3.1 Flash is cheaper on output tokens: $0.60/1M against $2.50/1M. Input tokens are $0.30/1M for Gemini 3.5 Flash Lite and $0.15/1M for MiniMax M3.1 Flash. Prices are the lowest listed API offer ModelCap observed, in USD per million tokens. For 1,000 requests with 2,000 input and 500 output tokens each (2M input + 0.5M output), the listed-rate estimate is $1.85 for Gemini 3.5 Flash Lite versus $0.60 for MiniMax M3.1 Flash. MiniMax M3.1 Flash costs 67.6% less in this scenario. This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the selected endpoint before budgeting.
Both publish a 1M-token context window. OpenRouter catalogue or provider-endpoint declaration. Limits can vary by provider and prompt length; a model-wide maximum has not been independently verified.
The two models do not share a coding benchmark board on ModelCap yet, so no head-to-head coding score is published; the ModelCap Index position is the closest overall signal.
Gemini 3.5 Flash Lite: No linked weights. MiniMax M3.1 Flash: Restricted license. Open weights mean the checkpoint can be downloaded and self-hosted under its licence. A missing weight link does not identify every API or chat product that offers a model.
