Hosting Llama 3 Billion parameters or similar other multimodal and used the exposed API's initially for development purposes, what would be the monthly cost.
Questions
- What is the expected scale of API usage (requests per month)?
- What are the primary use cases for the Llama 3B model?
- Are there specific latency or performance requirements?
- What is the target region for hosting the model?
- What type of data will the model interact with (text, images, etc.)?
- Is fine-tuning required, or will pre-trained weights suffice?
- Do you need multi-modal support from day one, or will it scale later?
- Do you need private hosting, or is a managed cloud solution acceptable? If yes any specific cloud requirement?
- What level of uptime and SLA is expected?
- Will the model be available 24x7 or we have to shutdown resources at night?

- Azure is the cheapest option overall.
- GCP offers slightly lower GPU pricing than AWS but higher idle instance costs.
- AWS is the most expensive primarily due to GPU and bandwidth pricing.
