Our verdict

Mixedbread suits developers who want a focused set of embedding and retrieval models rather than a broad catalogue of chat models. Input fees of $0.30 to $0.50 sit well above Salad, so try the $5 one-time credits first and watch what a real pipeline costs before you commit.

Who it suits

  • Teams shipping retrieval pipelines that need embeddings and reranking rather than a chat model.
  • Buyers who want a small vendor surface to review, backed by SOC 2 Type 2, ISO 27001 and GDPR.
  • Developers prototyping a search feature with $5 one-time credits in hand.

Who should look elsewhere

  • Price-first shoppers should look at Salad, where input fees start at $0.06.
  • Teams wanting general purpose models belong with Azure AI Foundry, whose catalogue runs to gpt 6 astra, gpt 6 luna and gpt 6 sol.
  • If you want many model families behind one key, Supascale AI lists DeepSeek V4 Pro, GPT 5.6 Sol and GPT 5.6 Terra.

Frequently asked questions

What does Mixedbread charge to get started?+

Input fees of $0.30 to $0.50 and output fees of $0.72 to $1.20 cover the models in the catalogue. New accounts can pick up $5 one-time credits to run a first prototype before committing a pipeline to this vendor.

Is there a free tier or trial credit?+

Yes, there is $5 one-time credits available to try the API at the start. Once that credit is spent, usage is billed at the normal rates, so treat it as a trial rather than a permanent free tier.

Which models can I call through the API?+

The catalogue covers Toast 1, mxbai rerank listwise and Wholembed V3. That is a narrow line-up aimed at search and retrieval work, not a general chat library, so check your use case fits before you build against it.

How large a context window do the models support?+

The largest context window is 131,000, which handles long documents but looks modest next to the 1,000,000 typical of the wider field. If you routinely pass very long transcripts, check the model you plan to use.

What security certifications does Mixedbread hold?+

The published certifications cover SOC 2 Type 2, ISO 27001 and GDPR. That set is what an enterprise security review usually asks for first, so it shortens the vendor questionnaire for teams buying API access for internal data.

How do I get support if something breaks?+

Support runs on email, help centre and community. That is a documentation and community path rather than a live desk, so keep your own runbooks and expect to work through the help centre when an incident lands.

Who is behind Mixedbread and where is it based?+

The provider is mixedbread ai inc., based in the United States. Working with a named US entity matters if you need a signed agreement, invoicing in dollars, or a data processing arrangement for an enterprise rollout.

How do its prices compare with other LLM API providers?+

Salad lists input fees of $0.06, well under the $0.30 to $0.50 here. Azure AI Foundry and Supascale AI compete on catalogue breadth rather than entry price, so Mixedbread fits only if the focused line-up is what you need.
