## Decision facts: DeepSeek-V3

- **Adopt for:** DeepSeek-V3 is a Python-based AI development tool, with documentation focused solely on licensing terms for both its codebase and models. It's unclear from the available information what specific features or capabilities

## Choose when

### Choose DeepSeek-V3 if…

- DeepSeek-V3 is primarily Python; SPTAG is C++.
- Tags unique to DeepSeek-V3: commercial use, mit license, python.
- - When you need an AI model that allows for commercial usage as DeepSeek-V3 explicitly supports this based on licensing provided.

### Choose SPTAG if…

- SPTAG is primarily C++; DeepSeek-V3 is Python.
- Tags unique to SPTAG: approximate-nearest-neighbor-search, c++, distributed serving, fresh-update.
- Also covers Vector Databases.

## When NOT to use DeepSeek-V3

- - If detailed documentation and clear feature descriptions are crucial as the repository lacks descriptive content.
- - When you require open-source model details or functionalities other than those related solely to licensing terms.

## 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.
