Choose SPTAG if…
- SPTAG is primarily C++; Agent-Reach is Python.
- Tags unique to SPTAG: approximate-nearest-neighbor-search, c++, distributed serving, fresh-update.
- Also covers Inference & Serving, Vector Databases.
When NOT to use SPTAG
- Developer Tools: A gateway is overkill when you're pinned to a single provider and model.
- Inference & Serving: Self-hosting rarely beats a hosted API on cost until you have steady, high-volume traffic.
- Vector Databases: Don't reach for a dedicated vector DB under ~100k vectors; pgvector on your existing Postgres is simpler to operate.
Choose Agent-Reach if…
- Agent-Reach is primarily Python; SPTAG is C++.
- Tags unique to Agent-Reach: agent-infrastructure, ai-agent, ai-search, automation.
- Also covers AI Agents, LLM Frameworks.
When NOT to use Agent-Reach
- 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.
- LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves.
