AI21 Labs API
Jamba and task-specific NLP models via API
What is AI21 Labs API?
AI21 Labs provides access to language models through an API, with Jamba as their primary offering alongside specialised NLP models for specific tasks. The service lets developers integrate these models into applications, websites, and workflows without building models from scratch. AI21 Labs targets software teams, product managers, and researchers who need reliable language processing capabilities but want to avoid the infrastructure costs of self-hosting. The freemium pricing model means you can test the models at no cost before committing to paid usage.
