What is MiniCPM5-2B?

What MiniCPM5-2B is for

Dense 2B-class open-source model for on-device and resource-constrained use, with native long-context support, tool calling, and agentic tasks. The registry places it in the OpenBMB catalog with a release date of 2026-09-06. 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 131,072 output tokens. It also declares reasoning and 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 MiniCPM5-2B 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

Use tasks with checkable intermediate steps and a clear final answer. Keep reasoning settings and tool access consistent across candidates. Count the tokens and retries needed for an accepted result; a context limit or reasoning flag does not predict task accuracy.

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 MiniCPM5-2B.

Tasks and inputs

MiniCPM5-2B 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 131.07K 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 apache-2.0. Check runtime support and size the complete model and working context for your expected concurrency.
