How much do DeepSeek V4.1 Flash or Mistral Medium 3.5 cost per month?

For an example workload of 20 million input tokens and 5 million output tokens per month: DeepSeek V4.1 Flash: $7.00. Mistral Medium 3.5: $68. 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 V4.1 Flash or Mistral Medium 3.5?

DeepSeek V4.1 Flash: 1M tokens of context; maximum output 944K tokens. Mistral Medium 3.5: 262K tokens of context; maximum output 210K 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 V4.1 Flash or Mistral Medium 3.5?

DeepSeek V4.1 Flash: Artificial Analysis SciCode 51.9%. Mistral Medium 3.5: Artificial Analysis SciCode 40.2%. 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 V4.1 Flash or Mistral Medium 3.5?

DeepSeek V4.1 Flash: Artificial Analysis output speed 213 tokens/s; time to first token 1.05 seconds. Mistral Medium 3.5: Artificial Analysis output speed 166 tokens/s; time to first token 2.21 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 V4.1 Flash or Mistral Medium 3.5 support images, audio or video?

DeepSeek V4.1 Flash: listed input formats: text, image; output formats: text. Mistral Medium 3.5: listed input formats: text, image, file; 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 V4.1 Flash or Mistral Medium 3.5 support tool calling and structured outputs?

DeepSeek V4.1 Flash: listed features: Function calling, Structured outputs, JSON mode, Reasoning, Log probabilities, Deterministic seed, Prompt caching. Mistral Medium 3.5: listed features: Function calling, Structured outputs, JSON mode, Reasoning, Deterministic seed. 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 V4.1 Flash or Mistral Medium 3.5?

DeepSeek V4.1 Flash: cached input price $0.02 per million tokens. Mistral Medium 3.5: cached input price not listed. 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 V4.1 Flash or Mistral Medium 3.5 available through an API?

DeepSeek V4.1 Flash: catalog status active; API identifier deepseek-v4.1-flash; listed API hosts not listed. Mistral Medium 3.5: catalog status active; API identifier mistral-medium-3-5; listed API hosts not listed. 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.
