IBM Granite 4.2 supports text tasks, structured output, and tool use in compatible applications.
Where it works well
- An IBM text model for summarizing, extraction, and structured tasks.
- Local inference after downloading a supported model and runtime.
- Works with text prompts and supplied context.
Common use cases
- Explain a small piece of code.
- Summarize supplied notes.
- Draft a change for review.
Know its limits
- These Granite variants are text-only.
- Tool use and file access require a configured application.
- The download size is not total running memory; longer context and other apps need additional headroom.
Run it on your computer
Start with a compressed download and a short conversation. Our estimate is about 8 GB of total RAM or Mac unified memory, with room for the operating system. The listed 2.2 GB download is the model file, not its full running memory use.
Check the model’s supported runtime and hardware before loading it. System RAM on a PC and unified memory on a Mac are different from dedicated NVIDIA VRAM. A memory match doesn’t guarantee compatibility or speed. Choose a smaller model if responses are too slow.
Use a desktop app that supports the listed model format, such as LM Studio or Ollama. Download the exact local variant, load it in Chat, and start with one small task. Model downloads need internet; local chat can work offline once the model is downloaded.
