Models on Brainbase

Kafka is model-agnostic: it runs any platform-billed model and is built to hand work across teams of agents — mix models per agent within one deployment.

About

Kafka is Brainbase's own agent runtime — the harness that powers Kafka agents on the platform, designed from the ground up for multi-agent orchestration, versioning, and evals.

It runs any platform model and integrates natively with the rest of Brainbase: shared tools and memory, agent hand-offs, and production observability.
