I only swapped the base URL and the key in my existing project. The OpenAI SDK worked as-is, nothing else to change.
The monthly quota is more than enough for my side projects. Not having to enter a card made it easy to just try it.
I signed up with email first and burned through 100K fast. Linking GitHub bumped it to 1M. Wish I'd noticed that sooner.
I pointed Claude Code at it and use it for personal projects in the evenings. Setup was literally two lines from the docs.
Streaming responses come through cleanly and I haven't had drops. Got my chatbot demo running in one evening.
Request history is a lifesaver. When a prompt goes sideways I can see exactly what I sent.
Some models slow down a bit at peak hours, but for a free service that's fair. The status page is transparent too.
We give our interns their own keys with limits. Seeing who used how much in the dashboard is reassuring.
No more separate accounts just to test one prompt across models. One key, change the model name, done.
Error messages actually make sense. When I hit a rate limit it tells me how long to wait.
Used it for my graduation project. My professor was surprised when I said the live demo cost me nothing.
Docs are short and clear, and the examples work copy-paste. More Python samples would be nice though.
Added it as a custom model in Cursor and use it all day while coding. Haven't run into quota issues so far.
Signed up with Google and sent my first request within two minutes. Didn't even have to wait for a verification email.
We use it for client prototypes. We can validate an idea before anyone has to pay for tokens.
Built a small internal text-to-SQL tool. The team uses it daily and setup took about half an hour.
Support for the Anthropic-style /v1/messages endpoint was a nice surprise. Moved my old scripts over unchanged.
We run LLM-based evals in our test environment. Everything gets tried here before we touch a paid provider.
Session list and security settings are well thought out. I signed out an old device with one click.
Added chat to my Discord bot. Friends on the server keep asking which model I'm running.
We prototyped the assistant in our mobile app here and kept costs at zero until user testing.
The model list gets updated often. New releases usually show up here within a few days.
Clean interface, I find things right away. The usage chart makes it easy to see what's left for the month.
Opened a couple of support tickets and got same-day replies. Didn't expect that from a free service.
At a hackathon everyone just made their own account instead of sharing one key. It ran without issues for the full 48 hours.
