NoteThe source confirms title (Claude 2), developer (Anthropic), releaseDate (Jul 11, 2023), and contextWindow (100,000 tokens). However, the source does NOT provide the specific inputPrice (8) or outputPrice (24) values—it only states the API is offered 'for the same price as Claude 1.3' without disclosing those prices. The safetyLevel field (ASL-2) is not mentioned in the source; the source only describes safety improvements qualitatively (2x better at harmless responses, red-teaming efforts). These pricing and safety-level claims are unverifiable from this source.
