TLM Playground

What is TLM Playground?
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.
Plumb

What is Plumb?
Plumb lets AI consultants build, deploy, and sell agentic workflows from a visual node editor without writing code. Each flow gets its own front end, runs on demand or on autopilot, and accepts text, audio, images, and video inputs. Access runs through a private beta request at signup.useplumb.com.
Where generic workflow tools stop at internal tasks, Plumb targets people who sell AI work. You can publish flows, push updates without cloning copies, set paywalls with one-time fees, subscriptions, or per-run charges, and share promo pages. That consultant-first monetization layer is the main split from broad no-code automation suites.
Freelance AI consultants, agency teams, and in-house champions who prototype multimodal model pipelines fit here best. Flows branch on conditions and route outputs to email, SMS, or Slack.
