IBM Granite is a family of open-source foundation models developed by IBM, optimized for business applications with a focus on efficiency, transparency, and trust. Released under the permissive Apache 2.0 license, Granite models range from small, edge-deployable variants to larger ones for complex tasks, available via watsonx.ai and Hugging Face.
What Is IBM Granite?
IBM Granite comprises decoder-only large language models (LLMs) trained on curated, license-permissible data for language, code, time series, and multimodal tasks. Key emphases include enterprise readiness: lower costs through efficient designs, built-in safety guardrails, and full customizability.
For beginners, Granite models power tools like chat assistants or code generators—download a small variant (e.g., 1B parameters) and run locally for quick tasks.
Intermediate users fine-tune on domain data via InstructLab for specialized applications.
Advanced deployments leverage hybrid MoE architectures for high throughput in agentic workflows or RAG systems. Granite integrates with watsonx for governed scaling, supporting on-prem, cloud, or hybrid setups.
Evolution of IBM Granite
Granite debuted in 2023 with 13B models for language/code.
Major releases:
- Granite Code (2024): Open-sourced for coding intelligence.
- Granite 3.0 (late 2024): Enhanced reasoning, multilingual support.
- Granite 4.0 (2025): Hybrid Mamba/Transformer for efficiency, Nano variants for edge.
