OpenPipe

Turn expensive, general-purpose LLM prompts into cheap, high-performance fine-tuned models.

OpenPipe is the developer platform and SDK for production-ready AI, abstracting the complexity of large language model fine-tuning. The platform captures existing prompt-completion pairs from your current provider (e.g., OpenAI) and uses that production data to train a new, specialized model. This process delivers immediate, measurable results: users routinely see up to 8x lower inference cost than GPT-4-class APIs and often achieve higher accuracy on specific tasks like data extraction or classification. OpenPipe supports a range of base models (Llama, Mistral, Qwen) and includes advanced tools like the Agent Reinforcement Trainer (ART) for continuous, data-driven optimization of AI agents.
