How do their numbers compare with Anthropic and OpenAI?

Extrapolating a bit, Moonshot AI provides Kimi K3 at $15 / $3 / $0.3 per million output/input/cached tokens. A 30% reduction would put K3.1 at roughly $12 / $2.4 / $0.24.

For comparison:

    Sol 6.1:    $10 / $2  / $0.10
    Opus 5.5:   $20 / $4  / $0.20
    Astra 6:    $50 / $10 / $1
    Fable 5.1:  $50 / $10 / $0.25

So Kimi K3.1 Pro would be generally competitive with the latest Sol and Opus models on API pricing. And that's before factoring in third-party providers, some of which serve Kimi K3 for significantly less than Moonshot. For example, inference.net offers K3 for $10.80 / $0.239 / $0.21.

(One caveat: A Claude or GPT subscription still gives you way more value compared to API pricing.)

Exciting times in any case! We really need more direct competition to OpenAI and Anthropic.

Edit: As another comment pointed out, official pricing is now available and it's about 2/3 the price of Kimi K3: https://platform.kimi.ai/docs/pricing/chat#model-pricing

It's too bad Kimi K3.1 Pro cached input is twice the price of Sol 6.1 at 20 cents.

Opus 5.5 is about the same price as Kimi K3.1 Pro Highspeed.

OpenAI allows you to use serviceTier=flex, dropping their price by 50%.

And not to mention the gargantuan amount of tokens you get with the US labs' subscription plans. I still cannot see a reason to use this as an end consumer.
