large semantic models limit

Hi powerbiexpert22 

Generally the Tenant / BI Administrator of your organization will be able to tell you which department is using Power BI Premium Capacity. 

As per the below link, the max memory gb mentions the allowed memory limit as per F-SKU in Fabric. 

If you do not have MS Fabric yet, then for large semantic models beyond 1 GB, need to have P1 capacity/F64 which allows max 25 gb memory. 

Without premium capacity, the shared capacity can be used which allows model size only up to 1 gb.

Hope I have answered your question.

Thanks,
