Tested Claude 4.5 Sonnet against cheaper alternatives on code modifications - data from Cline

Isn't this metric literally just how often it gives back a correctly formatted diff to be applied to the file? The code could be completely incorrect as long as the diff is able to be applied. As far as access model quality this is one of the least important metrics IMO. Especially when it is the difference of a couple percent. I am much more concerned about if the code in the diff is correct than if it is able to generate a correctly formatted diff. More on reddit.com

Anthropic launches Claude Sonnet 4.5, its best AI model for coding | TechCrunch

r/singularity on Reddit: GPT-4.5 is actually 2X-20X CHEAPER than Sonnet-3.7-thinking in many use cases.

February 28, 2025 -

It’s actually 2X-20X cheaper than Claude-3.7 when you measure on a full per message basis for many use-cases. The token cost only tells a small part of the story here, but in reality it’s the full interaction cost that matters.

A typical final message length is about 300 tokens, but Claudes reasoning can be upto 64K tokens, and you have to pay for all of that… Using 64K tokens of reasoning along with a final message of 300 tokens would result in a claude api cost of about 90 cents for that single message.

Meanwhile, GPT-4.5 only costs 4 cents for that same 300 token length message… That’s literally 20X cheaper cost per message than Claude in this scenario.

But ofcourse you’re not always maxing out claudes reasoning limit, but even if you only use 10% of Claude-3.7s reasoning limit, you will still end up with a cost of still about 10 cents per message, and that’s still more than 2X what GPT-4.5 would cost.

This is not some fringe scenario I’m talking about here either, 10% reasoning usage is not at all abnormal, but lets say even if Claude-3.5-sonnet only used 5% of it’s reasoning capacity, that still would only bring it to equal cost of GPT-4.5 and not cheaper.

if your prompt is tiny, the first message, and the answer is tiny... ok it's cheap. But usually the context is way more than 300 tokens

many use cases 64k tokens of reasoning 300 tokens of output I… don’t think this is as usual a case as you seem to believe. Nor do I believe their performance would be comparable. Also, you can precisely adjust how many thinking tokens Claude is allowed to use and Claude 3.7 non thinking might still compete or outcompete 4.5 in many use cases. This is cope.

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.

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

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.

Claude Haiku 4.5 Deep Dive: Cost, Capabilities, and the Multi-Agent Opportunity | Caylent

October 15, 2025 - Now, with the release of Haiku 4.5 in mid-October, we're seeing performance that’s close to Sonnet 4.5 (roughly on par with its predecessor Sonnet 4) at about a third of the price. We're seeing Anthropic's frontier capabilities diffuse down the model tier faster than any previous generation. This creates interesting opportunities for agent orchestration and scaled deployments. In this article, we're going to dive into the capabilities of Claude Haiku 4.5 and where we expect it will fit within the model ecosystem.
