Search and embeddings platform for building AI retrieval and agentic search

www.mixedbread.com ↗

Mixedbread ships weekly around Stores and Toast 1, turning retrieval into a full agent backend.

◆Current state
Mixedbread's changelog has gone from sparse to near-weekly. The product now centers on Stores, its search layer, and Toast 1, a deep-search model with MCP tools, hosted search tools and context management. Recent releases add speaker labels for audio and video, download links in search results, monthly budgets, store copies, and a Zero Data Retention attestation for bring-your-own-bucket customers.
◆Where it's heading
The arc has moved from embedding models and open-source libraries to a hosted retrieval platform with an agent on top. Autumn's releases split into two groups: file-type coverage that widens what Stores can ingest, and operational controls such as budgets, key scoping and attestations that production and procurement teams ask for.
◆Prediction
Expect more ingestion formats and enterprise controls on the same cadence, since both have been shipping almost every release cycle. Toast 1's tool surface is likely to keep following the OpenAI API shapes it already matches.

    Speaker Labels in Audio and Video

    Audio and video transcripts now label speakers, and each chunk carries them as filterable metadata, with m4a, aac and webm added. It widens what a Store can answer about, on the same day as other file-type additions.

    Spending Limits Are Now Monthly Budgets

    Spending limits become monthly budgets for usage beyond included credits, with a choice to pause API requests or keep serving. It gives teams an explicit decision about what happens at the cap, which matters once search sits in production.

    Download Links in Search Results

    Search results now include a file_url that downloads the source file for one hour, removing a second API call. It is a small change that shortens the path from a retrieved chunk to the original document.

    Try Toast 1 in the Agent Playground

    The agent playground lets users try Toast 1 deep search over Stores, the web, MCP servers and custom tools, and then see the code. It turns Toast 1's run of API features into something a developer can test without building first.

    Zero Data Retention Attestation for BYOB

    Bring-your-own-bucket customers can download a Zero Data Retention attestation to hand to security, legal or procurement. It is paperwork, but it is what regulated buyers ask for.

    Copy Store for Testing and Branching

    Copy Store duplicates a Store in one call without reprocessing, for snapshots or test environments. It treats a search index more like a branchable resource, a pattern that continues with Store tags.
