Best for

✓ Best for

TypeScript teams building server-rendered apps who need to integrate multiple LLM services.
Projects requiring a flexible and compatible way to call various hosted inference APIs.
Developers looking for an easy-to-integrate library that supports different LLM providers.

✓ Best for

Teams needing to deploy LLMs locally with minimal resources
Projects focused on edge computing where low latency is critical
Developers working in environments without reliable internet access

Not ideal for

✕ Not for

Teams needing real-time streaming capabilities (OpenLM is designed for batch processing).
Projects with strict budget constraints as it requires hosting and managing the underlying LLM services.

✕ Not for

Applications requiring real-time streaming capabilities
Scenarios where cloud-based services offer better performance or scalability
