difference?
It would look like pre-paid vs extended usage quotas. I hope for you all I'm wrong and It's just an error. More on reddit.com

July 19, 2025Is switching from Claude Code to GitHub Copilot (Sonnet 4.5) worth it?
I got to use both concurrently in my companies poc trials. Copilot mid summer was hot garbage with an 8k context window. It’s gotten a lot better context window for sonnet 4.5 is up to 120k tokens and they have made a lot of good improvements. I think it depends on your chats, vibe coding style and repo size. If you are routinely hitting 200k before summarizing and going with one long chat they extra for Claude might be worth for you. However value for dollar is better in copilot because you don’t pay for tokens you pay for enter presses. I think for most people copilot is a good substitute however if you are price insensitive. I still think Claude code is best in class. More on reddit.com

r/CLine on Reddit: Claude Sonnet 4.5 is now available in Cline
September 29, 2025 -
Hey everyone! Claude Sonnet 4.5 just went live in Cline.
Same pricing as Sonnet 4 ($3/$15), 200k or 1M context window, but the behavior is noticeably different. The model is way more terse -- it skips the narration and just executes. Where Sonnet 4 would explain every step, 4.5 chains operations together and only speaks up when it needs clarification.
The big improvement is how it handles long tasks. It naturally maintains state files (progress.txt, implementation notes, test manifests) and picks up exactly where it left off across sessions.
This pairs well with Cline's Auto Compact and Focus Chain features. When context gets compressed, the model's state files provide additional continuity.
Model string: claude-sonnet-4-5-20250929

Curious what the community thinks of the latest iteration of Claude Sonnet!

Very good post. I clearly noticed how it wastes less tokens. Same token price, less cost overall. Very good model. Hope they don't degrade it and rug pull.
