  title: EvolutionaryScale Forge ESM Cambrian Embeddings API
  description: Hosted inference API for the ESM Cambrian (ESM C) protein representation learning family. ESM C is a drop-in replacement for ESM2 with comparable or better accuracy at substantially reduced memory footprint. Provides encode and logits operations for sequence embedding workflows. Available in 300M, 600M, and 6B parameter checkpoints.
