If attractive, cloud providers could develop open models with their own investment, and sell hosted access as a business model. While Google checks these boxes, I haven't seen a Google much marketing focus upon their open models (Gemma) coupled with hosting. groq could conceivably train its own models, but groq's business model hosts open models (GPT OSS, Qwen 3, Llama 4 are currently their prominently advertised models on their site... which seems out of date to me) trained by other organizations.
