Launch HN: Talc AI (YC S23) – Test Sets for AI

Jan 18, 2024 - news.ycombinator.com
Max and Matt from Talc AI introduce their automated QA system for applications built on top of an LLM. They aim to tackle the issue of testing LLM applications and RAG systems, which is often done manually and can slow down development. Their solution involves benchmarking the general capabilities of language models and generating domain-specific test cases. They use a method called "named entity recognition" to extract facts from a chosen topic and then use an LLM to form a question and answer based on this fact.

Their testing and grading process is fast, driven by a combination of LLMs and traditional algorithms. Talc AI's business model is straightforward, charging for each test created and each example graded against the test. The team is eager to receive feedback from the HN community.

Key takeaways:

  • Max and Matt from Talc AI offer automated QA for applications built on top of an LLM, aiming to solve the issue of manual testing that slows down development and often leads to unexpected behavior.
  • They use ideas from academia to benchmark the general capabilities of language models, generating domain specific test cases that run against actual prompts and code.
  • Their testing and grading process is fast, driven by a mixture of LLMs and traditional algorithms, and can turn around in minutes.
  • Their business model charges for each test created and for each example graded against the test.
