Verdict

OpenRouter has become an essential tool for the AI development community. The ability to access hundreds of models through a single API is incredibly valuable, especially for developers who want flexibility and don't want to manage multiple provider accounts. The pricing is competitive, and the credit system is convenient. While it adds a middleman layer, the convenience factor far outweighs the minor additional cost for most use cases. Highly recommended for anyone working with multiple AI models.
