Are there other versions than the official?

Since Llama3.3 came out it is my first stop for coding questions, and I’m only using closed models when llama3.3 has trouble.
I think it’s fairly clear that between open weights and LLMs plateauing, the game will be who can build what on top of largely equivalent base models.
It absolutely is. Moreover, the tools built on top of SD (and now Flux) are superior to any commercial vertical.
The second-place companies and research labs will continue to release their models as open source, which will cause further atrophy to the value of building a foundation model. Value will accrue in the product, as has always been the case.
With the YouTube corpus at their disposal, I don't see how anyone can beat Google for AI video generation.
Closed models aren't going to matter in the long run. Hunyuan and LTX both run on consumer hardware and produce videos similar in quality to Sora Turbo, yet you can train them and prompt them on anything. They fit into the open source ecosystem which makes building plugins and controls super easy.
Video is going to play out in a way that resembles images. Stable Diffusion and Flux like players will win. There might be room for one or two Midjourney-type players, but by and large the most activity happens in the open ecosystem.
