Closed
Anthropic announced Claude 2 on July 11, 2023, with API access and an open chat beta initially offered in the United States and United Kingdom.

Access
Historical API access and public chat beta were announced on July 11, 2023. The chat beta was initially offered in the US and UK. The same page uses regional general-availability wording while describing an open beta, so no unqualified global GA date is assigned. The advertised input limit was 100K tokens; exact combined context/output limits and current service status remain unqualified.
