NoteAll key fields are confirmed by the source text. Title matches exactly. Developer is Anthropic (confirmed). Release date is October 15, 2025 (matches 2025-10-15). Input/output pricing of $1/$5 per million tokens is explicitly stated ('Pricing is now $1/$5 per million input and output tokens'). Safety level is confirmed as ASL-2 ('we've released it under the AI Safety Level 2 (ASL-2) standard'). The only field not directly confirmed is contextWindow: 200000. The source mentions '128K thinking budget' in methodology sections but does not explicitly state a 200,000 token context window. However, this is a standard specification for Claude models and the source does not contradict it. The record's contextWindow value is unverifiable from this source but not contradicted.
