# AI Models

> Choose the right model for your strategy and budget

Every agent decision is powered by an AI language model. You can switch models at any time from Modify Agent — the change takes effect on the next run.

All models run privately through [Venice AI](https://venice.ai). Your prompts, strategies, and trade data are never used to train any model.

## Choosing a Model

**Start with Claude Opus 4.8** — the recommended default, with an excellent balance of nuanced reasoning and cost. Reach for **Fable 5** when a strategy is unusually demanding and you want the most capable model available; drop to **Sonnet 4.6** when you want speed and efficiency.

**Step up to a flagship (Opus 4.8 / Fable 5) if:**

* Your strategy requires nuanced judgment across many signals simultaneously
* You run at lower frequency (4h+) and credit cost per run matters less
* Your backtests show the strategy benefits from deeper reasoning

**Step down to Grok Fast or DeepSeek Flash if:**

* You run at high frequency (15 min or 30 min) and want to preserve credits
* Your strategy is mostly rule-based with clear numeric thresholds
* You're in testing mode and don't need top-tier performance yet

## Chat Models

The model powering your **agent chat** is independent of your trading model. You can switch it per-session from the model picker in the chat header.

| Model         | Credits per Message | Best For                               |
| ------------- | ------------------- | -------------------------------------- |
| Grok Fast     | 15 cr               | Quick lookups, simple questions        |
| Grok 4.3      | 30 cr               | Strategy analysis, deeper questions    |
| Grok 4.5      | 70 cr               | Latest Grok — deeper strategy analysis |
| Claude Sonnet | 45 cr               | Nuanced strategy review                |
| Claude Opus   | 120 cr              | Deep portfolio analysis, major reviews |

Your chat model selection is saved and remembered across sessions.

<Tip>
  Use a cheaper chat model for quick questions ("what positions are you holding?") and switch to Sonnet or Opus when you want a serious strategy review.
