A4F

The premium tier is not worth it at all, most of the models are usually not available and return empty responses or error 500's as and some streaming not supported errors. Models are indeed duplicates upon duplicates of each other just to boost model numbers but in reality, they are the same models from different provider (and again not all of them work.) Lastly, I have noticed that a lot of the models don't behave like they should and spit out responses that don't make sense. For example, sonar (a perplexity model) identified as a google model and gave responses similar to gemini 2 flash.

Been using this for a month now, and honestly, it's a project that had no equal and no alternatives as long as you could use Gemini 2.5 pro for free. However, thanks to misusers perverts with no personal life (oh crap, just like me), access to it on a free basis is gone. But what remains is very generous free access to many other models. When using alternative projects there were always bugs when using LLM, but that is rare, and everything works quite stable, and there is a lot of potential in this, if the project takes off and the creator succeeds, I have no doubt it will become even more convenient, and easier to use, even for free users. I could only give advice not to rely on increasing the limits, and not to pay so much attention to the other LLM models, except for those that are most in demand. It would be great if only Gemini 2.5 pro remained on the site, with limits even smaller and worse than Google studio (10-20 messages per day), but guaranteed free for users from all over the world, albeit with very limited limits. But it's probably impossible, because the problem is that all sorts of obscene horrors come to Google via APIs, and Google can simply ban the APIs themselves. But if it was possible, then instead of a bunch of free (and generous on limits) BUT absolutely not outstanding models, there would be only the best, (such as Gemini 2.5 pro and Claude 4, although horrible on limits), the project would be alternative-free and unique, would occupy a monopolistic niche, providing such high-quality models, although limited (10-20 requests per day), but in the end free and guaranteed, and absolutely high-quality. (These are all just my dreams, but how sweet they are to me, and sound kind of reasonable).

I am delighted to use A4F's product as it offers extensive free access to a wide range of AI models, making it an invaluable resource for both developers and students. It's particularly pleasing that the platform provides access to premium models without any additional cost. The interface of A4F is intuitive and user-friendly, which significantly simplifies working with it. Additionally, the customer support service deserves special praise for its responsiveness and willingness to assist. Of course, like any evolving product, there are aspects that need refinement. Some users have noted issues with the availability and functionality of certain models, as well as encountering duplicates and errors. However, despite these shortcomings, A4F appears to be a promising tool with great potential for growth and improvement. Overall, I am satisfied with using A4F and look forward to future updates and enhancements that will make the platform even more convenient and effective.
