I’m building a project that needs AI generation for video, images, and 3D models, plus a way to combine clips, voice, music, and subtitles into a final MP4. I’m looking for APIs with a usable free tier.

Which services have you used in practice, and what were the catches (credit limits, watermarks, rate limits)? Is it better to use one platform for everything or chain separate APIs? Any open-source models worth self-hosting as a fallback?

I wanted to learn a high level language with a l C-like syntax, syntax with very little verbosity (but still C-like), with support for creating cross-platform graphical interface programs, and something that really doesn't require a lot of memory and low level knowledge.

I don't like C. it requires a lot of low-level knowledge. But I wanted a very similar syntax, but with more features and a language that is very popular so I have more opportunities.

i am thinking in golang, its a good choice for me and fits in my requirements?
