V4.1-Flash now supports web search, deep-thinking search, file parsing, URL reading and safety checks across the Messages, Responses and Chat Completions APIs. Public-facing apps must turn on safety checks. OCR, ASR and TTS are also available as standalone APIs, and tool use is billed on top of regular token charges.
