What is DeepSeek-V3?

What DeepSeek-V3 is for

Open DeepSeek MoE chat model for coding, math, and general reasoning. The registry places it in the deepseek family with a release date of 2024-12-26. This profile describes its documented interface and how to evaluate it for the intended task.

Inputs and request limits

The recorded inputs are text, with text output. The registry lists a 131,072-token context window and up to 8,192 output tokens. It also declares function calling. These are specifications, not a measured quality or speed ranking. A host can impose its own request limits and support a different subset of features.

Deployment and cost

The registry marks DeepSeek-V3 as an open-weight model. Check the linked checkpoint’s licence and runtime requirements before downloading or deploying it. Open weights describe availability, while licence terms determine permitted use. Local inference still requires hardware; a hosted route can charge separately.

No independently checked token rate is added from a hosting alias. Use the route’s current price and billing unit when comparing cost, including output, reasoning, cache behavior and retries where applicable.

What to test

Start with representative prompts and an agreed acceptance rubric. Include missing information, contradictory evidence and outputs that must follow a schema. Compare accepted results, complete request cost and response time under the same deployment conditions.

Evidence and related models

A supporting source document was retrieved for this entry. Specifications above remain attributed to the models.dev record unless the publisher supplies a more specific limit. SyncDev has not independently benchmarked DeepSeek-V3.

Tasks and inputs

DeepSeek-V3 is listed for Text generation. It accepts text and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.

Capacity and cost

Documented limits: 131.07K context and 8.19K maximum output. Measure a completed task using the prompts, documents and tools your application will use. Include reasoning and retries in the result.

Choosing a deployment

The weights are downloadable under DeepSeek Model License. Check runtime support and size the complete model and working context for your expected concurrency.
