Customer Reviews
Pretty smooth experience
I needed to get some GPT-4o access for a small side project, and a friend suggested OpenRouter. It was pretty easy to get signed up and generate an API key. I liked that they had a chat interface to test stuff out right there. The documentation was decent enough to get me going without much fuss. Everything just kinda worked, which is always nice when you're dealing with new tech. No drama, no weird billing surprises. I'd use it again if I need more models.
Consistently reliable API access
This wasn't my first time using OpenRouter; I've been a user for a few months now, mainly for Claude 3.5 Sonnet and Llama 3 API access. My experience this time was just as good as previous orders. The multi-model routing always works seamlessly, and I haven't had any downtime issues. It's really convenient to have all these models under one API key. The shared credits system is also a plus for managing multiple projects. It's why I keep coming back – the consistency and reliability are key for my development work.
Good value for trying models
I was looking for the most cost-effective way to test out some different AI models like Claude 3.5 Sonnet and Llama 3. OpenRouter's unified API really offered good value. I also appreciated that they gave some free credits as a new user, which helped me get started without much initial investment. It felt like a smart way to explore options without committing to multiple services. The token calculation was clear, so I always knew what I was spending. Definitely worth it for the price.
Easy API, worked well
I used OpenRouter for a quick API integration. Accessing the models was simple. It delivered as expected. Good experience.
Good service, minor UI nitpick
I used OpenRouter to access GPT-4o for a project last week. The unified API worked well, and it was straightforward to integrate everything. Pricing seemed fair, definitely competitive with using multiple services directly. The token usage analytics were helpful for keeping an eye on my spend, which I appreciated. My only small complaint is the dashboard could be a bit cleaner, sometimes finding specific settings took an extra click or two. But overall, a solid experience for developers looking for aggregated LLM access. Will likely use again.

Share tips, ask questions & help fellow shoppers save more
How do you guys add funds to OpenRouter? Can I just use a regular credit card or do they only take like crypto or something fancy?
Anyone know if they have any student discounts or like, free credits for new users? just getting started with some AI stuff.
Is OpenRouter good for image generation models? Or is it mostly just for text LLMs? Looking to build an app that needs both.
hey, trying to figure out if openrouter is really cheaper than just using OpenAI directly? like, for gpt-4o, is there a big difference?
