Tool Usage & Credits
How Skill tools consume your monthly credit allowance
How Skills Are Metered
Every Skill — speech-to-text, text-to-speech, image understanding, and image generation — draws down the same monthly credit allowance as chat completions. There are no separate per-Skill quotas: a Skill call consumes credits from your plan's allowance just like any other request.
For how the credit allowance, rollover, and pay-as-you-go overage work, see Credits & Usage.
Available Skills
| Skill | Tool |
|---|---|
| Speech-to-Text (ASR) | audio.transcribe |
| Text-to-Speech (TTS) | audio.synthesize |
| Image Understanding | image.describe, image.ocr |
| Image Generation | image.generate |
| Video Generation | coming soon |
Video Generation is coming soon — it will meter against the same credit allowance when it ships.
All Skills are available on every plan tier — nothing is locked behind a paywall. Higher tiers simply grant a larger monthly credit allowance.
Monitoring Skill Usage
View your Skill usage in the dashboard under Plan → Skills, and your overall credit balance under Plan → Usage. When your effective allowance (monthly quota
- rollover) and prepaid balance are exhausted, further calls — Skill or chat —
return
429until the allowance resets. See Credits & Usage.
Skills vs. Rate Limits
Credit consumption is separate from request rate limits:
- Rate limits cap requests within a 4-hour burst window.
- Credits govern your total monthly volume, weighted by per-model cost.
Both apply independently to Skill calls and chat completions alike.
