Optillm
OptiLLM is an AI reasoning and optimization framework that functions as an API proxy to enhance the response quality of large language models. It intercepts requests to apply inference-time reasoning logic and output refinement before returning results to the client.
The project distinguishes itself through a combination of inference-time search trees for logical verification and an anonymization pipeline that removes personally identifiable information from prompts. It further extends model capabilities by orchestrating external tools, including real-time code execution and autonomous web research.
The system provides broader infrastructure for model management, including load balancing across multiple providers and the ability to serve local models and adapters. It also handles structured output enforcement through schema constraints and manages extended conversation histories via a virtual context memory layer.
The proxy layer is designed to be compatible with standard API endpoints, allowing it to be integrated without changing existing client code.
