Tasks and inputs
Toast 1 is listed for Text generation. It accepts text and produces text. Use the publisher’s input format and preprocessing for your chosen deployment.
Toast 1 is Mixedbread’s text model for knowledge questions, multi-step retrieval and evidence synthesis with function calling.
Recorded modality support shows what this model can accept and produce. An undocumented modality is shown as unknown rather than assumed to be unsupported.

Toast 1 is a specialized Mixedbread model for knowledge-intensive questions and multi-step retrieval. It can work with a backend exposed through function calling. The value of that interface depends on which sources the tools retrieve and how well the final answer uses their evidence; the model cannot repair an incomplete or stale collection on its own.
The publisher lists a 131K-token context window and a 4K-token maximum output. Input messages, tool definitions, tool results and generated output all consume that context. Keep retrieved chunks focused and retain source identifiers, especially when several search rounds return overlapping material.
Toast 1 is available through Responses and Chat Completions interfaces. Mixedbread’s hosted tools can run the search loop over its Stores. A custom tool backend offers a different operational boundary, so select the interface that matches how your data is stored and how you audit retrieval.
Use questions that require one source, several sources and a justified refusal when the answer is absent. Check whether citations support the specific claim next to them. Measure retrieval misses separately from synthesis errors so that a model comparison does not hide a search-index problem.
Evaluate the total cost of tool calls and model output, plus the time to a supported answer. The absence of a token price on this profile means a sourced rate has not been recorded here. Consult the current pricing and tool documentation before budgeting a hosted search workflow.
Compare the model on the work you need to complete.

Documented limits: 131K context and 4K maximum output. Measure a completed task using the prompts, documents and tools your application will use. Include reasoning and retries in the result.
Use the model identifier and account requirements for the selected API route. Confirm its request limits and output format with one complete task before connecting a larger workflow.
These records share a directory category. Check the source card, output type and deployment requirements before treating a model as a replacement.
