Comparison
ai-gateway vs llm.ts
Verdict
Pick ai-gateway if ai-gateway from Ferro Labs supports over 30 LLMs with integrated caching, guardrails, A/B testing, and cost controls, making it ideal for managing multiple language models in a production environment; pick llm.ts if llm.ts is a TypeScript library for interacting with various Large Language Models via a unified API interface.

Choose ai-gateway if…
- ai-gateway is primarily Go; llm.ts is TypeScript.
- License: ai-gateway is Apache-2.0, llm.ts is MIT.
- Tags unique to ai-gateway: ai-gateway, litellm, llm-cost, llm-proxy.
- Also covers Inference & Serving.
- When you need to integrate more than 30 different LLM services including OpenAI and Anthropic
When NOT to use ai-gateway
- If your project only involves one or two LLMs which does not necessitate the gateway's broad compatibility features
- For small-scale projects that do not require comprehensive cost analysis tools
- When custom integration for specific guardrails is required, as ai-gateway offers generalized settings
Choose llm.ts if…
- llm.ts is primarily TypeScript; ai-gateway is Go.
- License: llm.ts is MIT, ai-gateway is Apache-2.0.
- Supports multiple providers including OpenAI, Cohere, and HuggingFace. Can be extended by opening a PR.
- Tags unique to llm.ts: ai, cohere, huggingface, llm.
- Also covers LLM Frameworks.
- You need to interact with multiple LLM providers like OpenAI, Cohere, and HuggingFace through a single API.
When NOT to use llm.ts
- If you require functionalities that are specific to one provider that are not yet unified or supported within the llm.ts framework.
- For projects that aim to minimize dependencies, though llm.ts itself claims zero dependencies, its reliance on external LLM providers could indirectly introduce complexities.
