alt Hacker News> Opus 4.5 really is at a new tier however. It just...works.
Literally tried it yesterday. I didn't see a single difference with whatever model Claude Code was using two months ago. Same crippled context window. Same "I'll read 10 irrelevant lines from a file", same random changes etc.

200k+ tokens is a pretty big context window if you are feeding it the right context. Editors like Cursor are really good at indexing and curating context for you; perhaps it'd be worth trying something that does that better than Claude CLI does?
That's because Opus has been out for almost 5 months now lol. Its the same model, so I think people have been vibe coding with a heavy dose of wine this holiday and are now convinced its the future.
I'm not familiar with any form of intelligence that does not suffer from a bloated context. If you want to try and improve your workflow, a good place to start is using sub-agents so individual task implementations do not fill up your top level agents context. I used to regularly have to compact and clear, but since using sub-agents for most direct tasks, I hardly do anymore.
I use Sonnet and Opus all the time and the differences are almost negligible
The context window isn't "crippled".
Create a markdown document of your task (or use CLAUDE.md), put it in "plan mode" which allows Claude to use tool calls to ask questions before it generates the plan.
When it finishes one part of the plan, have it create a another markdown document - "progress.md" or whatever with the whole plan and what is completed at that point.
Type /clear (no more context window), tell Claude to read the two documents.
Repeat until even a massive project is complete - with those 2 markdown documents and no context window issues.
