Model Comparison
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
- 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
