June 2, 2025Claude sonnet 3.5 pricing model
Here were my Anthropic costs over the month of June. There's a tiny bit of Sonnet-3.0 and Opus costs in there, but mostly Sonnet-3.5: https://imgur.com/ocyPpmC I'm a fairly fast reader and typist. I do only RP, although my AI responses are closer to 130-150 token replies. I use 15,000 ctx limit. When I use AI, it's up to 2 hours at most, but varies. I typically do chat with full context, but that's another thing that'll throw off your pricing is if you're chatting with a fresh chat it'll barely cost you anything because there's barely any input ingestion for Anthropic to read in. Also, output tokens barely will cost you anything. It's the input you need to worry about, but only at/near 15,000 ctx is when it gets a bit costly, so I choose not to go over 15,000 ctx.

r/Anthropic on Reddit: Claude-3 Pricing - Holy smokes!
March 5, 2024 -
I was about to dust off some code to re-evaluate claude-3 (claude-2 didn't do a good job for our needs) and then saw the pricing - Opus is $75/1m, Sonnet is $15/1m, and Haiku is $1.25/1m tokens for output!
Having said that, I'm mildly curious what $75/1m tokens gets me in terms of quality :)

I can say that I just used Opus to produce an outline of a chapter of a textbook. This is probably by top 2 interest in AI as a student, and Opus has produced what literally everything else has failed: a truly comprehensive outline. Even if it's missing stuff, it's not enough for me to care about.

September 29, 2025 - The pricing is the same as the previous Sonnet: $3/million input tokens and $15/million output tokens. This remains significantly cheaper than Claude Opus—$15/$75—but still quite a bit more than GPT-5 and GPT-5-Codex, both at $1.25/$10.
