alt Hacker NewsWhat's super interesting is that Opus is cheaper all-in than Sonnet for many usage patterns.
Here are some early rough numbers from our own internal usage on the Amp team (avg cost $ per thread):
- Sonnet 4.5: $1.83
- Opus 4.5: $1.30 (earlier checkpoint last week was $1.55)
- Gemini 3 Pro: $1.21
Cost per token is not the right way to look at this. A bit more intelligence means mistakes (and wasted tokens) avoided.

what is the typical usage pattern that would result in these cost figures?

Totally agree with this. I have seen many cases where a dumber model gets trapped in a local minima and burns a ton of tokens to escape from it (sometimes unsuccessfully). In a toy example (30 minute agentic coding session - create a markdown -> html compiler using a subset of commonmark test suite to hill climb on), dumber models would cost $18 (at retail token prices) to complete the task. Smarter models would see the trap and take only $3 to complete the task. YMMV.
Much better to look at cost per task - and good to see some benchmarks reporting this now.
