Cleanlab TLM
Free trialAPI that scores how trustworthy each LLM response is in real time
What is Cleanlab TLM?
Cleanlab's Trustworthy Language Model attaches a trust score to answers from any LLM so you can spot likely hallucinations before they reach users. It is aimed at developers running RAG systems, chatbots, agents and data extraction in production.
You can send TLM the prompt and an existing response from your own model, or a human-written one, and get back a trustworthiness score. It can also stand in for your LLM and return improved answers together with their scores, built on top of the frontier models you already use.
The documentation covers OpenAI-compatible Chat Completions and Responses APIs, structured outputs, tool calls, LangChain and LangGraph agents, and classification tasks. Latency and cost can be tuned per use case, and private deployment is offered for enterprises.
