AI21’s Jamba Reasoning 3B Redefines What “Small” Means in LLMs — 250K Context on a Laptop
The latest addition to the small model wave for enterprises comes from AI21 Labs, which is betting that bringing models to devices will free up traffic in data centers.
AI21’s Jamba Reasoning 3B, a “tiny” open-source model that can run extended reasoning, code generation and respond based on ground truth. Jamba Reasoning 3B handles more than 250,000 tokens and can run inference on edge devices.
The company said Jamba Reasoning 3B works on devices such as laptops and mobile phones.
Ori Goshen, co-CEO of AI21, told VentureBeat that the company sees more enterprise use cases for small models, mainly because moving most inference to devices frees up data centers.
