Claude Opus 4.5 - https://www.anthropic.com/claude/opus - Hybrid reasoning model that pushes the frontier for coding and AI agents, featuring a 200K context window

• And by “normal”, I mean that it is not the normal AI agent experience that I have had thus far. So far, AI Agents seem to be pretty good at writing spaghetti code and after 9 rounds of copy / paste errors into the terminal and “fix it” have probably destroyed my codebase to the extent that I’ll be throwing this whole chat session out and there goes 30 minutes I’m never getting back.
• Opus 4.5 feels to me like the model that we were promised - or rather the promise of AI for coding actually delivered.
