- The homepage lists four Anthropic models, with observation dates beginning September 26, 2026, and marks one observation stream as ended.
Field notes
The site says its observation began on 2026-09-26 and explicitly limits coverage to APIs, not product layers such as coding assistants. Its symptom index maps failures—such as new code fences, preambles, refusals, or longer outputs—to the relevant recorded behavior. The listed data is licensed CC BY 4.0; the site also says it retains access logs, including IP addresses, privately for 90 days before deletion.
