LiveBench quality versus score-adjusted output costEach dot is a reviewed major-model configuration and is colored by developer. Higher means a better LiveBench overall score. Farther left means lower estimated output cost after adjusting by the score. A dotted line connects the non-dominated frontier observations. When models are selected, their sourced families remain prominent, unrelated observations retain their developer colors at lower opacity, and an orange ring identifies each selected model.$0.0050$0.010$0.020$0.050$0.100$0.200$0.5006873788287Grok Build 0.1GLM 5.3 FlashGPT-5.6 Luna (max)DeepSeek V4 Flash Vision ExpGPT-5.6 Sol (max)Score-adjusted output cost per LiveBench case (log) →LiveBench overall →
The dotted frontier connects measured, non-dominated major-model observations. With a selection, sourced families stay prominent, unrelated observations retain their developer colors at lower opacity, and orange rings mark the selected model or models. Family lines connect models only when their sourced family and generation match. Cost is estimated from published output tokens and the lowest current USD output rate; it excludes input, caching, batch discounts, and provider-specific benchmark execution details.

This current-market view appears only when both compared models are reviewed current models with publisher-reported LiveBench token accounting and current sourced USD output rates.

Neither model has a larger sourced context window in this comparison. DeepSeek V4 Flash is 1,049K and Gemini 3.1 Pro is 1,049K.

Which performs better in benchmarks, DeepSeek V4 Flash or Gemini 3.1 Pro?+

Gemini 3.1 Pro leads the current overall benchmark count. The result uses 2 protocol-matched benchmarks from 2 publishers; it is not a universal quality score.

Can DeepSeek V4 Flash or Gemini 3.1 Pro be self-hosted?+

DeepSeek V4 Flash is the only model in this pair currently marked as self-hostable. DeepSeek V4 Flash is open weight; Gemini 3.1 Pro is not marked open weight.

Can DeepSeek V4 Flash and Gemini 3.1 Pro understand images?+

DeepSeek V4 Flash is not documented with image input; Gemini 3.1 Pro is documented with image input. This reflects supported input modalities, not vision quality.

Which can generate longer answers, DeepSeek V4 Flash or Gemini 3.1 Pro?+

Neither has a larger sourced maximum output. DeepSeek V4 Flash is — and Gemini 3.1 Pro is 66K.

Do DeepSeek V4 Flash and Gemini 3.1 Pro support reasoning and tool use?+

DeepSeek V4 Flash: reasoning. Gemini 3.1 Pro: reasoning, tool calling, and image input. Feature support does not establish relative quality.

Which is available from more inference providers, DeepSeek V4 Flash or Gemini 3.1 Pro?+

DeepSeek V4 Flash has 5 sourced provider routes; Gemini 3.1 Pro has 2, so DeepSeek V4 Flash has broader tracked availability.

Which offers better value, DeepSeek V4 Flash or Gemini 3.1 Pro?+

There is no universal value winner. Compare the input and output prices above with the matched benchmark result for your workload: cheaper tokens can be offset by different quality, token usage, latency, or provider availability.
