Source evidence
1 src · 1 checkpartial85%Haiku 4.5 · 4/30/2026
NoteThe source confirms title (Claude Opus 4.5), developer (Anthropic), releaseDate (Nov 24, 2025), inputPrice ($5 per million tokens), outputPrice ($25 per million tokens), and contextWindow (200,000 tokens). However, the record claims 'safetyLevel: ASL-3', which is NOT mentioned anywhere in the source text. The source extensively discusses safety improvements and alignment but never uses the designation 'ASL-3' or any comparable safety level classification. The source states Opus 4.5 is 'the most robustly aligned model we have released to date' but does not assign it a formal safety level code. This is a partial confirmation because most fields are verified but one critical field (safetyLevel) is unverifiable from the source.
