OpenPipe

OpenPipe is a post-training platform that enables teams to fine-tune and deploy large language models using supervised fine-tuning (SFT) and reinforcement learning (RL). It pairs RL experts with customers to identify high-impact use cases and delivers side-by-side evaluations that compare RL-trained agents against standard implementations on quality, compliance, and cost metrics. The platform includes the open-source agent reinforcement trainer (ART) framework. Key features include continuous RL optimization via GRPO-powered feedback loops, on-premises and VPC deployment, regulatory compliance (SOC 2 Type II, HIPAA, GDPR), role-based access controls, immutable audit logs, dedicated support with SLAs, predictable enterprise pricing (up to 8× lower inference cost than GPT-4-class APIs), and a unified observability hub with live dashboards and guardrails. OpenPipe is trusted by companies like Wispr, Y Combinator, Zapier, and Method.
