AI21 Labs

AI21 Labs builds the Jamba model family, a hybrid SSM/transformer architecture offering large context windows at lower inference cost than dense transformers.

LiteLLM prefix: ai21/
Status: Stub — routes through OpenAI-compatible client
Docs: https://docs.ai21.com/reference/jamba-15-api-ref

Variable	Required	Description
`AI21_API_KEY`	Yes	API key from studio.ai21.com

Quick Start

Single-Backend (env vars)

BACKEND=ai21 AI21_API_KEY=your-key cargo run -p anyllm_proxy
# Docker:
docker run -e BACKEND=ai21 -e AI21_API_KEY=your-key -e PROXY_OPEN_RELAY=true -p 3000:3000 followthewhit3rabbit/anyllm-proxy

LiteLLM YAML Config

model_list:
  - model_name: jamba-1.5-large
    litellm_params:

`jamba-1.5-mini`	256k	Faster, lower cost

Notes

AI21 exposes an OpenAI-compatible endpoint at https://api.ai21.com/studio/v1. The native AI21 API format is not implemented; this provider uses the OpenAI-compatible path only. Jamba's SSM/transformer hybrid architecture handles long-context prompts more efficiently than standard attention-only models. Tool use is not supported via the OpenAI-compatible endpoint.
