Prices are USD per million tokens at standard rates, excluding batch and caching discounts. Bold indicates the better figure where one is objectively better. Values we could not confirm from the provider are shown as “Not verified” rather than estimated.
Pricing tiers: Gemini 3.1 Pro: Base tier is $2/$12 per million tokens; prompts above 200K tokens are priced at $4/$18. Prefer the Preview API id `gemini-3.1-pro-preview` (not a GA alias).
Gemini 3.1 Pro
Google's Pro tier in limited preview since 2026-02-19, with a 1.05M-token context window and multimodal input.
Best for
- Very long documents
- Multimodal input
- Google Workspace integration
Watch out
Scored 12% on DeepSWE, far below every other model here including budget tiers — weak on agentic coding specifically. Pricing also steps up to $4/$18 above 200K tokens. Wire calls to `gemini-3.1-pro-preview`.
Qwen3.8-Max
Alibaba's hosted Max-class API — 2.4T MoE with a 1M context window (max input 991,808), vision, and managed tools. Distinct from the Hugging Face Qwen3.8-2.4T-A95B checkpoint.
Best for
- Agentic coding
- Multimodal knowledge work
- Long-context delivery
Watch out
This row is the hosted Qwen3.8-Max API, not the downloadable checkpoint. The open-weight Qwen3.8-2.4T-A95B card is catalogued separately and does not include the API's vision, non-thinking, or built-in tool extras.

DeepSWE “Best” picks the highest published reasoning effort per model (not the highest pass rate). Small gaps may not be statistically meaningful — confirm on deepswe.datacurve.ai.
Common questions
Gemini 3.1 Pro vs Qwen3.8-Max
Answered from the verified figures on this page rather than general guidance.
Is Gemini 3.1 Pro or Qwen3.8-Max cheaper for input?
Both cost $2 per million input tokens at standard rates, so input price is not a deciding factor between them.
Is Gemini 3.1 Pro or Qwen3.8-Max cheaper for output?
Qwen3.8-Max is cheaper at $6 per million output tokens, against $12 for Gemini 3.1 Pro — roughly 2.0× the price. Output tokens usually dominate a real bill, so weigh the output rate more heavily than the input rate. These are base rates; Gemini 3.1 Pro has tiered pricing: Base tier is $2/$12 per million tokens; prompts above 200K tokens are priced at $4/$18. Prefer the Preview API id `gemini-3.1-pro-preview` (not a GA alias).
Which has the larger context window, Gemini 3.1 Pro or Qwen3.8-Max?
Gemini 3.1 Pro accepts 1.05M tokens against 1M for Qwen3.8-Max. This only matters if you routinely send very long documents or large codebases.
Should I use Gemini 3.1 Pro or Qwen3.8-Max?
Both sit in the frontier tier, so the choice usually comes down to price and context rather than capability. Gemini 3.1 Pro suits very long documents; Qwen3.8-Max suits agentic coding.

Choosing between them
Tier and workload decide this more reliably than a leaderboard position does.
If both sit in the same tier, the decision usually comes down to context window and output price rather than headline capability — output tokens dominate real bills.
If one is a step up within the same provider, the useful question is whether your hardest task actually fails on the cheaper tier. Most production volume — classification, extraction, summarization — does not.
