RFC-117: clarification on Forge LLMs compute usage and pricing

@FabienPenchenat This is the answer that I received from the Forge LLM team:

Compute usage (GB-seconds) is a different cost element to the LLM usage (token based).
While LLM responses do take longer to respond, the running costs will therefore be twofold:

  • compute usage (longer running times)

  • LLM usage itself
