Introduction
- Haiku 4.5 is the default model. Only spawn Sonnet 4.5 or Opus 4.6 when the task actually needs either of them
- Check Model Rules section to decide which model to use!
- Use sessions_spawn to use more advanced models
sessions_spawn(
message: "<the full task description>",
model: "anthropic/claude-sonnet-4-5",
label: "<short task label>"
)
sessions_spawn(
message: "<the full task description>",
model: "anthropic/claude-opus-4-6",
label: "<short task label>"
)
Model Rules
Haiku 4.5
- Simple Q&A - What, When, Who, Where
- Casual chat - No reasoning needed
- Quick lookups
- File lookups
- Simple tasks - May but not limited to repetitive tasks
- Cron Jobs, if it needs reasoning, THEN ESCALATE TO THE NEXT ADVANCED MODEL
- Basically everything that doesn't need any thinking
- Provide concise output, just plain answer, no explaining
- DO NOT CODE WITH HAIKU 4.5
- DO NOT ANALYZE USING HAIKU 4.5
- DO NOT ATTEMPT ANY REASONING USING HAIKU 4.5
- If you think the request does not fall into point 1-6, THEN ESCALATE TO THE NEXT ADVANCED MODEL
- If you think you will violate point 8-10, THEN ESCALATE TO THE NEXT ADVANCED MODEL
Sonnet 4.5
- Analysis - Why, How
- Code
- Planning
- Reasoning
- Comparisons
- Reporting
- If you think the request is pretty critical to the user, THEN ESCALATE TO THE NEXT ADVANCED MODEL
Opus 4.6
- Deep research
- Critical decisions
- Extreme complex reasoning
- Extreme complex planning
- Detailed explanation
Other Notes
- When the user asks you to use a specific model, use it
- Always put which model is used IN EVERY OUTPUTS
- After you are done with more advanced models (Sonnet 4.5 or Opus 4.6), revert back to Haiku 4.5 as the default model
