Choosing AI Models

Choosing the right model has a direct impact on how smart, autonomous, and reliable your AI assistant feels.

In general: smarter models produce better planning, better decisions, and better tool use.

Quick recommendation​

If you want the best balance for most users:

  • Start with Grok (recommended default)
  • Use Op.46 or Sonnet 4.6 when you want maximum autonomy and intelligence

Why model choice matters​

The model controls how well your agent can:

  • Understand complex tasks
  • Plan multi-step actions
  • Recover from mistakes
  • Use tools and integrations effectively
  • Keep context over longer workflows

If you pick a weaker model, your assistant may feel less capable and require more manual guidance.

Model comparison (practical)​

Benefits

  • Strong quality for day-to-day agent tasks
  • Good speed/cost profile
  • Great default choice for most users

Tradeoffs

  • For the most demanding reasoning tasks, you may still prefer a top-tier max-intelligence model

Op.46​

Benefits

  • Excellent reasoning and planning depth
  • Strong autonomy for complex workflows
  • Very capable for high-stakes agent decisions

Tradeoffs

  • Usually higher cost than lighter options
  • Can be slower on some workloads

Sonnet 4.6​

Benefits

  • Very strong intelligence and instruction following
  • Great for advanced agent workflows
  • Strong balance of reliability and capability

Tradeoffs

  • Typically costs more than budget-tier models

Common questions​

Which model should I choose first?​

Use Grok first. It is the recommended starting point for most Sulla setups.

What if I want the smartest possible agent behavior?​

Use Op.46 or Sonnet 4.6. These are currently top choices when you want maximum autonomy and intelligence.

Does a smarter model really make a difference?​

Yes. Smarter models make the assistant feel more capable because they reason better, plan better, and execute complex tasks with less hand-holding.

Should I use a local model instead?​

Only if you are an advanced user with a high-end machine. Most users will get better quality and easier setup using remote models.

  1. Start with Grok as your default model.
  2. Test your core workflows.
  3. If you need more intelligence/autonomy, move to Op.46 or Sonnet 4.6.
  4. Keep one model as your stable default and only switch when there is a clear quality gain.
