Common questions
IBM Granite 4.2
Answered from the verified figures on this page rather than general guidance.
What is IBM Granite 4.2's context window?
IBM Granite 4.2 accepts about 128K tokens of context. That only matters if you routinely send very long documents, large codebases, or multi-turn histories that approach that limit.
What is IBM Granite 4.2 best for?
IBM Granite 4.2 is a balanced tier from IBM. It suits enterprise/edge, regulated industries, on-device. Smallest sizes are not frontier; pick the 7B for general work.
Can I self-host IBM Granite 4.2?
IBM Granite 4.2 publishes open weights, but self-hosting depends on the licence, hardware footprint, quantisation quality, and serving stack. A hosted API is often cheaper until you have measured throughput and concurrency on your own hardware.
