## Choose when

### Choose Agent-Reach if…

- License: Agent-Reach is MIT, SPIN is Apache-2.0.
- Tags unique to Agent-Reach: agent-infrastructure, ai-search, bilibili, claude-code.
- Also covers LLM Frameworks, AI Agents.

### Choose SPIN if…

- License: SPIN is Apache-2.0, Agent-Reach is MIT.
- Tags unique to SPIN: deep-learning, fine-tuning, python, large-language-models.
- Leaner open-issue backlog (24).

## 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.

## When NOT to use SPIN

- Last GitHub push was 795 days ago (dormant maintenance, May 8, 2024). Validate activity before betting a new project on SPIN.
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
