Granite 4.0 Tiny Preview: IBM’s Lightweight Multilingual Expert Model Redefines Long-Context AI Processing

What Is It?

Granite 4.0 Tiny Preview is IBM’s latest 7-billion parameter MoE model, optimized and instruction-tuned based on Granite 4.0 Tiny Base. It focuses on improving instruction-following capabilities and is well-suited for handling extended inputs and complex prompts.

The model is released under the open-source Apache 2.0 license, reflecting IBM’s commitment to creating commercially viable multilingual AI foundations.

Key Features

• Multilingual Support: Covers 12 languages, including English, German, French, Chinese, Japanese, Spanish, Arabic, Korean, and more.

• Advanced Instruction Following: Delivers precise responses to user commands across dialogue, Q&A, summarization, and information extraction tasks.

• Long-Context Handling: Supports input lengths up to 8192 tokens, ideal for documents, meeting transcripts, and extended interactions.

• Multi-task Capabilities: Excels at code generation, classification, function calls, retrieval-augmented generation (RAG), and beyond.

• Lightweight Deployment: Optimized for efficiency, making it suitable for edge computing and resource-constrained environments.

Technical Overview

The model leverages a Mixture-of-Experts (MoE) architecture, where only a subset of expert subnetworks is activated per token. This allows for greater parameter scalability with lower computational cost and improved generalization.

Granite 4.0 Tiny Preview is trained on a diverse set of instruction datasets, combining open-source and IBM-generated synthetic data. It uses both supervised fine-tuning and reinforcement learning techniques to align model behavior with human-like instruction-following.
