Claude Opus 4.8: 1M context, adaptive thinking, mid-conversation system messages | Claude Master

Описание: Get Claude Master — founding price $47 (limited spots): https://claudemaster.net/founding?utm...

Claude Opus 4.8 launches as Anthropic's most capable generally available model, adding a 1M token context window by default, adaptive thinking to reduce wasted reasoning tokens, and mid-conversation system messages that preserve prompt cache hits when instructions change mid-session.

What's new in this update:
• What changed:*
• *1M token context window* by default, with 128k max output tokens
• *Adaptive thinking* — reasoning fires only when needed, reducing wasted tokens vs. Opus 4.7 at the same effort level
• *Mid-conversation system messages* — update instructions mid-session without busting your prompt cache (no beta header required)
• *Refusal categories in `stop_details`* — your app now knows why Claude declined, so you can route accordingly
