## Choose when

### Choose surogate if…

- surogate is primarily C++; Agent-Reach is Python.
- License: surogate is Apache-2.0, Agent-Reach is MIT.
- Tags unique to surogate: llms, llama, deep-learning, fine-tuning.
- Also covers Model Training.

### Choose Agent-Reach if…

- Agent-Reach is primarily Python; surogate is C++.
- License: Agent-Reach is MIT, surogate is Apache-2.0.
- Tags unique to Agent-Reach: agent-infrastructure, ai-search, bilibili, claude-code.
- Also covers AI Agents, Developer Tools.

## When NOT to use surogate

- Model Training: Try prompting and RAG first; fine-tuning is the answer to style/format, not missing knowledge.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.

## When NOT to use Agent-Reach

- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
- AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
