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

I saw support was added to Bedrock and then the commit was reverted, then a fix was made that excluded Bedrock. Is there a blocker to support 4.5 in Bedrock?

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.
