TLM Playground vs Ava

TLM Playground is Cleanlab's documentation hub for the Trustworthy Language Model (TLM), a model generation API that scores how reliable any LLM response is in real time. Each answer gets a trustworthiness score between 0 and 1, flagging hallucinations and reasoning errors before they reach users. Install the Python client with pip install cleanlab-tlm, set a CLEANLAB_TLM_API_KEY, and call TLM.prompt() to generate scored responses or get_trustworthiness_score() to audit outputs from your existing stack.

Most hallucination detectors focus on faithfulness to retrieved context. Metrics like RAGAS check whether an answer matches source documents but miss factual errors when the context is thin or confusing. TLM uses model uncertainty estimation rather than LLM-as-judge prompting, and Cleanlab publishes benchmarks showing 3x greater precision than RAGAS in RAG workflows. It needs no labeled training data on your domain, which sidesteps the drift problem that breaks custom evaluators.

ML and AI engineers building RAG pipelines, chatbots, and agent systems use TLM to gate low-confidence outputs, route them to humans, or swap in fallback answers. The API covers structured outputs, tool calls, classification labels, and multi-turn conversations, not just plain text completions.

Ava turns spoken conversations into live captions on your phone, computer, or browser. Deaf and hard-of-hearing users get real-time text for video calls, lectures, doctor visits, and in-person chats. The service mixes automatic speech recognition with optional human Scribes when a meeting needs ADA-grade accuracy.

Most caption apps stop at whatever accuracy the speech model gives you. Ava lets you stay on free or low-cost AI captions for everyday use, then add a professional Scribe for 99% accuracy when the stakes are higher. Ava Connect drops captions into Zoom, Google Meet, or Teams without rebuilding your meeting workflow around a single platform.

Students, employers, clinics, and event hosts use Ava to caption classes, standups, telehealth sessions, and venue talks. Individual plans start free with 40-minute sessions; organizations can add custom dictionaries, SSO, and scheduled Scribe time.
