Granite 3.1 8B Instruct

Granite-3.1-8B-Instruct is an 8 billion parameter instruction-tuned model from IBM's Granite team, released in December 2024. It is fine-tuned from Granite-3.1-8B-Base on permissively licensed instruction data plus synthetic long-context datasets, with supervised fine-tuning, RL alignment, and model merging in a structured chat format.

The model supports a 131K token context window and 12 languages, targeting business use cases like summarization, RAG, code tasks, and function calling. It is released under Apache 2.0 and runs locally via Ollama, vLLM, and Transformers.
