Introducing Toast 1, our first specialised search agent.

Toast 1 sets a new Pareto frontier for agentic search models.

Frontier search quality, across all domains, 12x faster, at 1/10th of the price.

New: Connect Mixedbread to your OpenTelemetry provider

Teams build agents that grep, search, use Toast 1 for deep search with Mixedbread. Their actions should be transparent and observable.

Now you can export every agent action to your OpenTelemetry provider (Langfuse, Braintrust, etc.):

→ trace every search and tool call
→ debug retrieval and agent behavior
→ measure latency and identify bottlenecks
