Introducing the Sigma5C Model Observatory

A public home for dated AI-system observations, model records and the methods used in the lab.

Sigma5C observes and measures how AI systems behave under defined conditions over time.

We provide research, data, and custom observations to understand and apply AI.

The public Model Observatory brings together dated observation pages, model records and company and project pages. Readers can follow the links between an observation, its model family, the provider or project, and related work.

Under the Hood describes the model routes, agent harnesses, vocabulary and methods recorded in the lab. Sigma5C is working towards a human-guided autonomous AI research lab and data company: people set direction, review records and approve consequential changes while agents assist with research and data creation.

This release is a static public research site. The planned API beta is a separate release. New observations are added after their public facts have been checked against their source records.

Our recurring notes will include Model Monday, Wrapper Wednesday, Throwback Thursday and Feature Friday. The company blog is the canonical archive; LinkedIn posts link back to the corresponding article.

AI-generated & AI-scored. Every observation on this site is produced and judged by AI, and AI makes mistakes. Treat each result as a recorded observation under a declared protocol, as of its date. Method and marker legend
