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

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.
