How this model is billed. ai21.com/pricing lists 'Jamba Large' at $2 / 1M input tokens and $8 / 1M output tokens (pay-as-you-go on the AI21 Platform). AI21's own docs (docs.ai21.com/docs/jamba-foundation-models) confirm the alias 'jamba-large' currently points to 'jamba-large-1.7-2025-07', so 1.7 is the version those prices apply to; 398B params / 94B active, 256K max tokens. The pricing page shows only the family name 'Jamba Large', not a per-version price. Cloud-hosted usage (Bedrock, SageMaker, Azure) is priced by the cloud provider, not by AI21.
