OpenPipe

OpenPipe built developer-focused tools for fine-tuning large language models to specific applications. Its platform captured prompts and completions from a customer's existing codebase and used them as training data to create smaller, specialized models that could replace general-purpose LLMs with lower cost, latency, and improved accuracy. OpenPipe also developed open-source tooling for training AI agents; its platform has since migrated to Weights & Biases and CoreWeave.
