Multi-Model Orchestration for Complex Edits
Splits complex code edits across specialized models: a retrieval model gathers context, a large model writes the changes, and smaller models apply them

} Use when
- Multi-file code edits need broad context plus precise changes
- One model is too costly or too weak for all sub-tasks
- Phases can pass distilled results instead of full history
Avoid when
- Simple edits that one model handles well
- Team cannot afford to debug a multi-stage pipeline
Problem
A single large language model, even if powerful, may not be optimally suited for all sub-tasks involved in a complex operation like multi-file code editing. Tasks such as understanding broad context, generating precise code, and applying edits might benefit from specialized model capabilities.
Solution
Employ a pipeline or orchestration of multiple AI models, each specialized for different parts of a complex task. Different models excel at different cognitive tasks—specialization beats generalization. For code editing, this could involve:
- A retrieval model to gather relevant context from the codebase.
- A large, intelligent generation model (e.g., Claude 3.5 Sonnet) to understand the user's intent and generate the primary code modifications based on the retrieved context.
- Potentially other custom or smaller models to assist in applying these generated edits accurately across multiple files or performing fine-grained adjustments.
Pass only distilled conclusions between models, not full conversation histories. This reduces token costs and maintains clean phase boundaries. This approach leverages the strengths of different models in a coordinated fashion to achieve a more robust and effective outcome for complex operations than a single model might achieve alone.
Example
How to use it
- Use this when tasks need explicit control flow between planning, execution, and fallback.
- Start with one high-volume workflow before applying it across all agent lanes.
- Define ownership for each phase so failures can be routed and recovered quickly.
- Pass only distilled conclusions between model phases, not full conversation histories.
Trade-offs
- Pros: Improves coordination across multi-step workflows, reduces hidden control flow, and enables cost optimization through right-sized model selection.
- Cons: Adds orchestration complexity and more states to debug.
