Deep dive

The capability footprint differs most on vision: Gemini 3.1 Flash-Lite, multimodal input: Gemini 3.1 Flash-Lite, function calling: Gemini 3.1 Flash-Lite, tool use: Gemini 3.1 Flash-Lite, structured outputs: Gemini 3.1 Flash-Lite, and code execution: Gemini 3.1 Flash-Lite. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.

For cost, DeepSeek Coder V2 lists $0.14/1M input and $0.28/1M output tokens on the cheapest tracked provider, while Gemini 3.1 Flash-Lite lists $0.25/1M input and $1.50/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts DeepSeek Coder V2 lower by about $0.44 per million blended tokens. Availability is 2 providers versus 3, so concentration risk also matters.

Choose DeepSeek Coder V2 when coding workflow support and lower input-token cost are central to the workload. Choose Gemini 3.1 Flash-Lite when coding workflow support, larger context windows, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.

FAQ

Which has a larger context window, DeepSeek Coder V2 or Gemini 3.1 Flash-Lite?

Gemini 3.1 Flash-Lite supports 1.05m tokens, while DeepSeek Coder V2 supports 128k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.

Which is cheaper, DeepSeek Coder V2 or Gemini 3.1 Flash-Lite?

DeepSeek Coder V2 is cheaper on tracked token pricing. DeepSeek Coder V2 costs $0.14/1M input and $0.28/1M output tokens. Gemini 3.1 Flash-Lite costs $0.25/1M input and $1.50/1M output tokens. Provider discounts or batch pricing can still change the final bill.

Is DeepSeek Coder V2 or Gemini 3.1 Flash-Lite open source?
