But if you compare to Anthropic's models? The cost difference is huge. Anthropic is clearly concerned that people are realizing they are expensive, since the Opus 5 blog post dedicated a lot of time to talking about how cheap the model was compared to the competition... but this doesn't hold water when I haven't seen any independent benchmarks claiming Opus 5 is cheaper than GPT-5.6-Sol, even if it is supposedly closer.

GPT-5.6-Sol is pretty competitively priced, but not all American frontier models are, and even 10% to 30% is still significant for any commodity that's as fungible as frontier models often are.

> as you say that could go down to 20-30% cheaper

I never said anything about 20% to 30%. We don't know how much it actually costs to host this model yet, and that will determine the final price. It could be just a little less, or it could be a lot less.

> once you account for quantisation

There will be no need to account for quantization. Kimi models have been 4-bit only since at least K2.5. They don't release or serve models in higher precision than that. This isn't one of those situations where LLM inference providers are debating between serving 16-bit, 8-bit, or 4-bit, and I have never seen a publicly hosted, paid model that was hosted in less than 4-bit, even if hobbyists will use sub-4-bit quantizations sometimes locally.
