Pricing.
Two ways to pay, one for each way of using Kael: by usage through the API, or by subscription through the app.
Pay For What You Use.
Pricing is usage-based, per million tokens, and each model has its own price. Kael Beta costs the same at Low, High and Max. Kael Pro Beta, the most thorough model, costs more per token at both of its levels. You are billed once, for your input and the final answer, nothing else.
| Model | Thinking levels | Input | Cached input | Output |
|---|---|---|---|---|
| Kael Betakael-beta | low (default), high, max | $3.00 | $0.60 | $10.00 |
| Kael Pro Betakael-pro-beta | z-low (default), z-high | $8.00 | $1.60 | $25.00 |
Prices are per 1M tokens. Cached input is billed at $0.60 on Kael Beta and $1.60 on Kael Pro Beta, which is 80% below the input price, and only for the part of a request that actually hits the cache. Every level of a model costs the same per token; a higher level thinks for longer, so a request takes more time and can use more tokens. You are billed once, for your input and the final answer, nothing else. See the console for the exact numbers.
One Subscription.
Harness, the coding agent, and Chat, the conversation, are covered by a single subscription. Exact pricing lives on the app.
