How billing works

Cogito charges per input token and per output token, with separate rates for each. Output is generally 1.5–3× more expensive per token than input — output tokens are generated sequentially on GPU/Trainium and consume more compute. For each request you’re billed: 
cost = (input_tokens × input_rate) + (output_tokens × output_rate)
Both rates are listed per model on the model catalog.

​
Context cache discount

When you re-send the same prefix tokens (a long system prompt, a reference document, a multi-turn conversation), Cogito automatically caches them and bills cached input tokens at 50% of the standard input rate. No code change required. You can verify the discount applied: every response includes usage.cached_input_tokens alongside prompt_tokens and completion_tokens.

​
Fine-tuned variants

Your fine-tunes price the same per-token rate as the base model. We don’t charge a premium for serving them.

​
Hard spend caps

Set a maximum monthly spend in Dashboard → Billing. Once you hit it, requests return: 
{
  "error": {
    "type": "insufficient_quota",
    "code": "spend_cap_reached",
    "message": "Monthly spend cap reached. Raise the cap or top up to continue.",
    "request_id": "req_..."
  }
}
This protects you from runaway loops and DDoS-by-bug. We never silently bypass your cap.

​
Free credits

New accounts start with $5 in free credits. No card required to spend them. Card is required only when you top up beyond the free tier.
