Azure OpenAI pricing for GPT-6.1 Sol is $2 per million input tokens and $10 per million output tokens on a Global deployment: exactly what OpenAI charges for the same model. Pin the deployment to a Data Zone and the rate goes up. Microsoft’s price list adds 10% for a US Data Zone and 20% for…

Cerebras charges $0.35 and $0.75 for the same model and advertises about 3,000 tokens per second. Ordinary GPU hosts sell it for as little as…

Kimi K3 pricing on Moonshot’s own API is $3 per million input tokens and $15 per million output tokens. That is the list price, not what you have to pay.

So on 12 October we embedded our entire site,…
