Brain & Models
The Brain tab controls which AI model powers your agent's intelligence. Different models have different strengths.
Supported providers
| Provider | Models | Strengths |
|---|---|---|
| OpenAI | GPT-4o, GPT-4o-mini, GPT-4-turbo, GPT-3.5-turbo | Best all-around, strong tool use, fast |
| Anthropic | Claude 3.5 Sonnet, Claude 3 Haiku, Claude 3 Opus | Long context, nuanced reasoning, safe |
| Google Gemini | Gemini Pro, Gemini Flash | Multi-modal (images + text), fast |
| Mistral | Mistral Large, Mistral Small | Cost-effective, fast, good for simple tasks |
| TinyGPT | Default model | Built-in; no API key needed, works out of the box |
Configuration
| Setting | Description | Range |
|---|---|---|
| Provider | Which AI company's model to use | Select from dropdown |
| Model | Specific model version | Depends on provider |
| Temperature | Controls randomness/creativity | 0.0 (deterministic) to 1.0 (creative) |
| Max tokens | Maximum response length | Depends on model (typically 1K-128K) |
| API key | Your API key for the provider | Bring your own or use saved keys |
Azure OpenAI support
For enterprise users with Azure-hosted OpenAI:
| Setting | Description |
|---|---|
| Azure endpoint | Your Azure OpenAI endpoint URL |

Choosing the right model
| Use case | Recommended model | Why |
|---|---|---|
| General support bot | GPT-4o-mini or TinyGPT | Fast, cost-effective, handles most queries |
| Complex reasoning | GPT-4o or Claude 3.5 Sonnet | Better at multi-step thinking |
| Long document Q&A | Claude 3.5 Sonnet | 200K token context window |
| Budget-conscious | Mistral Small or GPT-3.5-turbo | Cheapest per-token cost |
| Image understanding | Gemini Pro | Native multi-modal support |
| No API key setup | TinyGPT | Works immediately, no configuration |
Temperature guide
| Temperature | Behavior | Use when |
|---|---|---|
| 0.0 | Always picks the most likely response | Factual Q&A, classification, data extraction |
| 0.3 | Mostly consistent with slight variation | Customer support, documentation help |
| 0.7 | Balanced creativity and consistency | General conversation (default) |
| 1.0 | Maximum creativity and randomness | Creative writing, brainstorming |
Tip
Start with TinyGPT to test your agent quickly without API key setup. Once you're happy with the agent's behavior, switch to a provider-specific model for better quality or lower cost.
Warning
TinyGPT runs on your TinyCommand credits. Other providers use your own API key, so model usage is billed by that provider at its own prices. Check both your credit usage and your provider's billing regularly.
Note
API keys are stored securely and never exposed in the agent's public-facing chat. You can also save keys at the workspace level to reuse across multiple agents.
