How much do DeepSeek V3 or Gemini 2.5 Flash cost per month?

For an example workload of 20 million input tokens and 5 million output tokens per month: DeepSeek V3: $10. Gemini 2.5 Flash: $19. These are token-only estimates using the displayed rates, without caching discounts, additional tool charges or taxes. Actual bills depend on usage and endpoint pricing.

Which has a larger context window: DeepSeek V3 or Gemini 2.5 Flash?

DeepSeek V3: 164K tokens of context; maximum output 16K tokens. Gemini 2.5 Flash: 1M tokens of context; maximum output 66K tokens. Context capacity and maximum output are separate limits. A larger context window allows more material in a request but does not guarantee more accurate answers.

Which is better for coding: DeepSeek V3 or Gemini 2.5 Flash?

DeepSeek V3: Artificial Analysis SciCode 35.8%. Gemini 2.5 Flash: Artificial Analysis SciCode not listed. Compare coding results within the same evaluation, then test representative tasks from your own codebase. A missing score is not a zero, and a single benchmark does not establish the best model for every programming task.

How do Arena Elo, DesignArena, Intelligence Index and MMLU-Pro differ?

These evaluations measure different tasks and use different scales. Arena Elo and DesignArena ratings must remain separate, as must Artificial Analysis Intelligence Index and MMLU-Pro. Compare models within the same evaluation rather than combining scores. Missing results are marked Not listed, not treated as measured zeroes.

Which responds faster: DeepSeek V3 or Gemini 2.5 Flash?

DeepSeek V3: Artificial Analysis output speed not listed; time to first token not listed. Gemini 2.5 Flash: Artificial Analysis output speed 190 tokens/s; time to first token 0.46 seconds. Output speed measures generation throughput, while time to first token measures the initial wait. Real-world latency also depends on the API provider, request size and load; missing measurements cannot establish a speed winner.

Do DeepSeek V3 or Gemini 2.5 Flash support images, audio or video?

DeepSeek V3: listed input formats: text; output formats: text. Gemini 2.5 Flash: listed input formats: file, image, text, audio, video; output formats: text. Input and output support are different capabilities: accepting an image does not mean a model generates images. Confirm formats and file limits for the endpoint you plan to use.

Do DeepSeek V3 or Gemini 2.5 Flash support tool calling and structured outputs?

DeepSeek V3: listed features: Function calling, Structured outputs, JSON mode, Deterministic seed. Gemini 2.5 Flash: listed features: Function calling, Structured outputs, JSON mode, Reasoning, Deterministic seed, Prompt caching. Only recorded capabilities are shown; an unlisted feature is not proof that it is unsupported. Availability can vary by API provider, so confirm tool calling and JSON schema support for your chosen endpoint.

Can prompt caching reduce the cost of DeepSeek V3 or Gemini 2.5 Flash?

DeepSeek V3: cached input price not listed. Gemini 2.5 Flash: cached input price $0.03 per million tokens. Caching may reduce charges for eligible repeated input when supported by the endpoint. A listed cached rate does not guarantee every request qualifies; cache duration, minimum token counts and any write charges depend on the provider.

Are DeepSeek V3 or Gemini 2.5 Flash available through an API?

DeepSeek V3: catalog status active; API identifier deepseek-v3; listed API hosts StreamLake, DeepInfra. Gemini 2.5 Flash: catalog status active; API identifier gemini-2.5-flash; listed API hosts Google, Google, Google, Google AI Studio, Google AI Studio, Google, Google AI Studio. Catalog status is not a live availability check. Before integrating, verify the provider's documentation, endpoint access, rate limits, regional availability and data-handling terms.
