Training a model is not only expensive, but also technically challenging on a pure engineering level. Cluster management, storage, backups, access, fault recovery, and so forth. While crowdfunding training of a LLM is a nice idea, personally I would not invest in something this "uncooked". Why do you believe you are able to properly manage $5M+ and the infrastructure necessary? I've met several people that believe if you just get the funding the rest is super easy, and it's slightly infuriating.

Apart from that, I agree with the other comments that the website looks unprofessional and llama is a bad name to use for this.

If I would want to give this a shot, I would first get engineers committed with a plan to start as soon as there's funding, set up a non-profit to handle the operation, and make sure that potential investors get the impression I knew what I was doing by providing a full plan and timeline, including addressing the legal challenges (among those, make it clear that the resulting model will be commercially usable and not sued to death. Are you planning on guaranteeing indemnification or do you want to release the model as-is? Etc)
