Pricing

LLM Engine is an open-source project and free self-hosting will always be an option.

A hosted option for LLM Engine is being offered initially as a free preview via Scale Spellbook.

Self-Hosted Models

We are committed to supporting the open-source community. Self-hosting LLM Engine will remain free and open-source.

We would love contributions from the community make this even more amazing!

Hosted Models

Once the limited preview period has ended, billing for hosted models will be managed through the Scale Spellbook product.

Scale Spellbook leverages usage-based spending, billed to a credit card. Details on usage-based pricing will be shared with everyone before completing the limited preview.
