Coral offers three model tiers that control which AI model powers your assistant. You can switch tiers at any time from the Settings page.

​
Model tiers

TierDefault ModelAlternativeBest for
LightGemini 3 Flash—Fast, cost-effective tasks
StandardClaude Sonnet 4.6—Balanced everyday use
ProClaude Opus 4.6Gemini 3.1 ProComplex reasoning, advanced tasks
The Standard tier is selected by default when you set up your assistant.
Use the Light tier for simple tasks to conserve credits. Switch to Pro when you need the most capable reasoning for complex analysis, coding, or multi-step workflows.

​
Changing your model

  1. Go to the Settings page.
  2. Find the Model section.
  3. Select a tier (Light, Standard, or Pro).
  4. If the tier has multiple models (Standard and Pro do), choose your preferred model.
  5. Click Apply.
The change takes effect immediately — no restart required.

How tiers affect credits

Each AI model request costs credits based on the model and token count:
  • Light tier models use the fewest credits per request.
  • Standard tier models use a moderate amount.
  • Pro tier models use the most credits per request.
Your credit usage is tracked on the Settings page under Usage & Billing. Individual message costs are also shown inline in the chat. See Billing & Credits for plan details and pricing.
If you configured your own API keys during onboarding (BYOK), model requests are billed directly by your AI provider — Coral credits are not consumed unless you have Coral fallback enabled.
