Reef

Reef: Open-source infrastructure that connects agent inference, feedback, model training, and versioned deployment.

Reef is open-source continual learning infrastructure built for self-improving agents. It serves as inference-native infrastructure that allows agents to learn from live traffic and continually update their weights and configuration. Users can start a local stack, send a provider-native request, and grade the receipt that Reef returns. The platform supports open-source development under the Apache-2.0 license. It helps developers build agents that adapt through feedback and training loops.
