OpenRouter
OpenRouter gives you one simple API to access more than 200 different AI models from many providers. It includes several completely free models such as DeepSeek, Llama, and Moonshot, along with paid options for heavier use. This makes it very convenient because you do not need separate accounts for each model. Developers use it to test different AI models, build chatbots, generate content, or power smart features in their applications. The free models come with reasonable rate limits that are sufficient for learning, personal projects, and light usage. OpenRouter is especially helpful when you want to experiment with various AI capabilities without managing multiple services.
