More Details Connect to Claude

Connect your Braintrust AI observation platform to any agent and maintain intense logic evaluation capabilities directly over conversation.

What you can do

  • Project Analytics — Retrieve logic banks and branch isolated AI test sets
  • Experiments — Create real trace regression tests appending unique LLM scoring iterations
  • Datasets — Query accurate Ground Truth sets and insert new prompt templates mapping your system accuracy
  • Prompt Versioning — Grab perfectly frozen semantic prompts without editing core code boundaries

How it works

  1. Add this server to your AI cluster
  2. Bind your personal Braintrust API ID variables
  3. Leverage complex model tuning pipelines querying native AI logic regressions on chat

Automate LLM regression analyses effortlessly. Rather than scrolling tables, your bot handles strict semantic checking via Braintrust infrastructure logic directly.

Who is this for?

  • AI Developers — push Ground Truth evaluation text datasets on the fly testing prompt differences
  • Machine Learning Engineers — track specific variable distributions checking accurate regressions remotely
  • Product Teams — observe exact string prompts dynamically pushing features validating response styles
  • Data Scientists — construct massive matrices and evaluate test runs without pulling script queries

See how to talk to your AI agent using Braintrust.

List all active test datasets configured under Braintrust.

I've fetched your Ground Truth repositories. There's 1 dataset active under ID 4a83b9c named 'Support-Responses-Testing'. Should I list the rows nested there?

Look up prompt template using specific ID XYZ.

Prompt XYZ returns successfully. It tracks specific {{user}} tags targeting strict instructions enforcing a professional tone. The JSON mapping version is 1.0.4. Do you need further metadata?

Analyze recent experiments across multiple models testing behavior.

Extracted the historical trace boundaries. Experiment run ID V3 generated a 94% alignment score compared to the previously logged V2 base structure matrix mapping differences on false positives.

Yes. Utilizing the `insert_dataset_row` method, you can effortlessly inject exact JSON tracking payload mapping strings directly inside the text corpus evaluating the final results.
