Model slots

Magnitude uses seven model slots — one for each agent role:
  • Lead — the lead agent you interact with directly. Use your strongest model here.
  • Explorer — codebase investigation. Fast and capable.
  • Planner — converts findings into implementation plans. Fast and capable.
  • Builder — performs code changes. Fast and capable.
  • Reviewer — validates quality and completion. Fast and capable.
  • Debugger — diagnoses failures. Fast and capable.
  • Browser — visual browser tasks. Must be a visually grounded model. To see the full list of supported browser agent models, click here.
Configure each slot independently via /settings. The setup wizard sets sensible defaults based on your provider: a strong model for the lead, a fast capable model for workers (explorer, planner, builder, reviewer, debugger), and a visually capable model for the browser agent.

Switching models

Use /settings to connect providers and change models. You can also use /provider or /model directly.

Visually grounded models

Most modern frontier models support visual grounding, so there are plenty of options to choose from. Below is the full list of models compatible with the browser agent, organized by provider.
