Does a long system prompt cost money on every request?

Yes. Each request sends its system prompt as input, so its tokens are billed every time. Keep system prompts focused, and move rarely-needed detail into the conversation only when it's relevant.

Good to know#

• Flash $1.60/$3.40, Max $1.80/$3.80, Heavy $2.00/$4.40 per 1M tokens in/out.
• The usage in each Model API response is what's billed.
