AI21 introduced Jamba 3B that outperformed Qwen 3 4B and IBM Granite 4 Micro in reasoning quality.

🟢 What's the secret in architecture?
- a combination of Transformer attention and Mamba state-space layers.
- The Mamba part efficiently processes long sequences without heavy attention caches,
- while the Transformer layers maintain the ability for complex reasoning.

As a result, the model uses less memory, delivers high speed, and runs smoothly even on laptops, GPUs, and mobile devices.


🟠 Features?
- Context: up to 256K tokens.
- Speed: about 40 tokens/sec even on long contexts, while other models slow down sharply.

Higher efficiency compared to AI21 - 2–5× performance improvement over competitors thanks to a smaller KV cache, hybrid architecture.

On "intelligence versus speed" graph, Jamba 3B surpasses Gemma 3 4B, Llama 3.2 3B, and Granite 4.0 Micro.


Truly superior intelligence and faster generation on Hugging face
