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. 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 |
| Claude Sonnet | 45 cr | Nuanced strategy review |
| Claude Opus | 120 cr | Deep portfolio analysis, major reviews |
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.
