See the comparison table for live GitHub stats and shared categories. ### When should I choose gateway over openlm? Choose gateway over openlm when gateway is primarily TypeScript; openlm is Python; Tags unique to gateway: ai-agents, anthropic, language-model, prompt-engineering; Also covers Developer Tools; When you require access to more than 200 different LLMs through a unified interface, ensuring seamless integration and management in your development projects. ### When should I choose openlm over gateway? Choose openlm over gateway when openlm is primarily Python; gateway is TypeScript; Requirements: Installation is as simple as using pip to install the openlm package.; Tags unique to openlm: cohere, huggingface; Use when you want to seamlessly integrate different LLM frameworks, like Hugging Face or Cohere, under a uniform interface similar to OpenAI’s. ### When should I avoid gateway? When your project only involves a few specific LLMs that don't require a comprehensive, unified SDK; in this case using direct SDKs from those LLM providers could simplify your setup. If you are working primarily in languages other than TypeScript and need an SDK that supports those environments natively for better performance or community support. ### When should I avoid openlm? Avoid when you require maximum performance optimization specific to one LLM framework, as using an intermediary library like OpenLM might introduce additional overhead. Not suitable if you are strictly working with models that do not have Python support or don't fit within the frameworks supported by OpenLM. ### Is gateway or openlm more popular on GitHub? gateway has more GitHub stars (605 vs 368). Stars measure visibility, not whether either tool fits your constraints. ### Are gateway and openlm open source?
