What is Trinity Mini?

Trinity Mini is Arcee AI's open-weight mixture-of-experts language model. It has 26 billion total parameters, with about 3 billion activated per token.

What those sizes mean

The active count describes a part of the token-level computation. The total count still matters when storing and loading the weights. Do not budget hardware as though this were a dense three-billion-parameter checkpoint. Measure memory use with your chosen precision, context length and batch size.

Runtime and interface

The published configuration allows 131,072 context positions. The model card documents several serving options, including vLLM and a hosted route. Tool calling and reasoning output need the appropriate parser in the selected runtime. A model loading successfully is only the first compatibility check.

Evaluate completed tasks

Test code against executable checks and tool calls against a strict schema. Count incorrect arguments, unsupported assumptions and repair attempts. For retrieval or document work, include questions whose answers are absent from the input; a useful model should not fill every gap with an invention.

The checkpoint uses the OpenMDW-1.1 license. Review that license for your deployment rather than assuming every open-weight model has identical terms. Browse Arcee AI models, or use the comparison tool to inspect another candidate.

Compare the model on the work you need to complete.

Tasks and inputs

Trinity Mini 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. 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 OpenMDW-1.1. Check runtime support and size the complete model and working context for your expected concurrency.

Frequently asked questions

Check the publisher documentation, exact model or checkpoint ID, runtime compatibility and current access terms. Test representative inputs and record failures, latency and total cost before changing a production route.

These records share a directory category. Check the source card, output type and deployment requirements before treating a model as a replacement.
