Model Stacks
A model stack is a preset of three AI models: a primary model and two fallbacks. If the primary model is unavailable, your bot automatically tries the next one.
Available stacks
| Stack | Primary | Fallback 1 | Fallback 2 | Best for |
|---|---|---|---|---|
| Indie | MiniMax M2.5 | Kimi K2.5 | DeepSeek V3.2 | Budget-friendly, great for everyday tasks |
| Big Tech | Gemini 2.5 Flash | Claude Haiku 4.5 | GPT-5 Nano | Balanced speed and quality |
| Premium | Claude Sonnet 4.6 | Gemini 3 Pro Preview | GPT-4o | Best quality, higher credit usage |
How to switch stacks
- Go to your Dashboard
- Open the Settings tab
- Select a new stack from the Model Stack dropdown
- Click Save
The change takes effect immediately. Your bot restarts with the new models.
How fallback works
Your bot tries models in order:
- Primary model — used for every message
- Fallback 1 — used if the primary is down or rate-limited
- Fallback 2 — used if both above fail
This happens automatically. You don’t need to do anything — your bot stays responsive even if a model provider has issues.
Credit usage
Different models cost different amounts per message. As a rough guide:
- Indie — lowest cost, ~$0.001–0.005 per message
- Big Tech — moderate cost, ~$0.003–0.01 per message
- Premium — highest cost, ~$0.01–0.05 per message
Actual costs depend on message length. Check your Dashboard usage tab to monitor spending.
