Pricing
SPLAI is a pay-per-use service. You only pay for what you use.
What are tokens?
AI models process text by breaking it into small units called "tokens." Pricing is based on the number of tokens used.
You (= Input)
Tell me next week's weather forecast for Tokyo. I want to know if I need an umbrella.
↑ This message ≈ 25 tokens
AI (= Output)
Here's next week's Tokyo weather forecast. Monday: Sunny 28°C Tuesday: Cloudy 26°C Wednesday: Rain 23°C ← Bring an umbrella ...
↑ This response ≈ 100 tokens
Input
The content of the messages you send to the AI.
Output
The content of the responses generated by the AI.
Tokens are not the same as characters. In Japanese, one character can be 1–3 tokens. In English, one word ≈ 1 token.
Example: "Hello" → ~1 token, "こんにちは" → ~3 tokens
※ Token counts vary by model. The above are approximate estimates.
Image Generation Pricing
Image generation pricing is based on both the processing used before generation and the final generated image.
Processing-based
Longer instructions, reference image analysis, and prompt refinement can increase the text-processing portion of the cost.
Per generated image
Each completed generated image also adds the model's per-image output charge.
Failed generations
Failed image generations are not billed as successful usage. We only bill completed generations that persist a result message.
