Overview
OpenPipe is a post-training platform for LLM agents that uses supervised fine-tuning and reinforcement learning to train smaller models on a customer's own tasks and metrics. Training is built on its open-source agent reinforcement trainer (ART), with GRPO feedback loops that keep models learning from production data. The stack can be deployed on-prem or in a customer's VPC.

Strengths and trade-offs
Strengths
- Open-source ART framework underpins the RL training
- Runs on-prem or in your VPC; data and weights stay in-network
- SOC 2 Type II, HIPAA and GDPR support, RBAC and audit logs
- GRPO feedback loops retrain models on fresh production data
Trade-offs
- No published prices; a demo and an enterprise agreement are required
- Sold as a paired engagement with OpenPipe's RL experts, not self-serve
- OpenPipe is joining CoreWeave, so ownership and roadmap may change
- Cost and accuracy claims come from OpenPipe's own case study
