# Supported AI Models & Pricing

> Every AI model available in Runable with provider, context window, and credit cost by tier.

Runable gives you access to models from Anthropic, Google, OpenAI, and xAI. Which models you see depends on whether you are in Agent Mode or Chat Mode.

## Agent Mode tiers

In Agent Mode, you select a tier. The agent uses the corresponding model.

| Tier                                        | Best for                                              | Credit cost |

| <Badge size="sm">Lite</Badge>               | Fast tasks, simple edits, quick answers               | Lowest      |

All models support file input, reasoning, tool use, and vision.

## How credits work with models

Every AI operation costs credits. The cost depends on the model used and the amount of input and output processed. Higher-capability models cost more credits per message.

<Tip>
  For most tasks, <Badge color="blue" size="sm">Pro</Badge> is the best balance of quality and cost. Use <Badge color="purple" size="sm">Max</Badge> for complex reasoning or when Pro produces unsatisfactory results. Use <Badge size="sm">Lite</Badge> for quick edits and simple questions.
</Tip>

<Note>
  Model availability may change as new models are released and older ones are retired. The models listed here reflect what is currently available.
