Scales efficient language processing with open-source accessibility.
OpenPipe
Platform for enterprises and developers to fine-tune, host, and train production-grade LLMs and multi-turn agents with OpenAI-compatible APIs.

About OpenPipe
OpenPipe is a Web and API platform designed for enterprises and developers who need to fine-tune large language models and train production-grade AI agents. The platform reduces prompt costs and latency by providing a unified SDK for model integration, production prompt logging, and request capture. It supports fine-tuning workflows with pruning rules to convert expensive prompt pipelines into smaller, more efficient models. OpenPipe offers model hosting with OpenAI API-compatible request formats, along with caching and evaluation tools to compare model performance and speed. The Agent Reinforcement Trainer (ART), an open-source reinforcement learning framework, enables multi-turn agent training using Group Relative Preference Optimization (GRPO) for realistic conversational rollouts. The platform emphasizes an end-to-end workflow from production logging to fine-tuning, evaluation, and deployment, supporting real-world agent workflows with reported cost and latency reductions and improved task success rates.
