When was DeepSeek-V3 released, and is it still maintained?

DeepSeek-V3 was released on 2024-12-26. Its catalog status is stable. Check the model page for deprecation notices before you build a long-lived integration on it.

How should you set the output budget for DeepSeek-V3?

Set max_tokens on DeepSeek-V3 to the longest response your task actually needs, not the 8,192-token ceiling. Keeping the cap tight reduces worst-case spend and shortens tail latency. Raise it only for tasks that demonstrably need longer output.

What is the max output length for DeepSeek-V3?

DeepSeek-V3 returns up to 8,192 output tokens per request, within a 128,000-token context window. Cap the response with the max_tokens parameter so a single call cannot run past your budget.

What should you evaluate before moving production traffic to DeepSeek-V3?

Before switching production traffic to DeepSeek-V3, run a pilot on a representative slice of your traffic and check output quality, latency at peak concurrency, and cost per request. Verify the error and retry behaviour, and confirm the request limits you depend on match your plan.

Can you call DeepSeek-V3 with the OpenAI SDK you already use?

Yes. DeepSeek-V3 is reachable through an OpenAI-compatible endpoint, so an existing OpenAI SDK client works after pointing the base URL at MixRoute and setting the model parameter to deepseek-v3 . Keep your current request and response handling.

Model detail

DeepSeek-V3

Provided by DeepSeek

Delisted Pay-as-you-go

DeepSeek-V3 is the latest model from the DeepSeek team, building upon the instruction following and coding abilities of the previous versions. Pre-trained on nearly 15 trillion tokens, the reported evaluations reveal that the model outperforms other open-source models and rivals leading closed-source models.

DeepSeek-V3 is the latest model from the DeepSeek team, building upon the instruction following and coding abilities of the previous versions.

What should you check before using it?

128,000 context, 8,192 output tokens

DeepSeek model that supports tool calling and structured output. Knowledge cutoff: 2024-12. Released 2024-12-26.

Why use it through MixRoute?

Swap the base URL, keep the DeepSeek-V3 client

MixRoute serves DeepSeek-V3 on the OpenAI-compatible endpoint /v1/chat/completions; point your existing client at https://api.mixroute.ai/v1 with the model ID deepseek-v3 and re-run your integration tests.

Capabilities & compatibility

Unconfirmed capabilities stay "Unknown," no guesses

Tool calling

DeepSeek-V3 supports function and tool calls.

EX Send a tools definition; the response returns tool_calls to execute and feed results back.

Structured output

DeepSeek-V3 can produce JSON-formatted output on demand.

EX response_format: { type: "json_schema" } forces valid JSON output.

Streaming

DeepSeek-V3 supports streamed responses.

EX stream: true streams tokens incrementally, so chat UIs render as they arrive.

Prompt caching

DeepSeek-V3 supports prompt caching under supported routing conditions.

EX Keep the system prompt and tool definitions at the start of the request; repeated prefixes are automatically billed at the cache-read rate.

OpenAI SDK

Call DeepSeek-V3 through MixRoute's OpenAI-compatible endpoint.

EX Change base_url to https://api.mixroute.ai/v1; everything else follows the OpenAI style.

FAQ

The current model record does not publish a numeric rate limit for DeepSeek-V3. Confirm the quota for your plan in the console, then run a short load test at your expected concurrency to establish the effective ceiling before production.
