Watch out
Thinking is enabled by default; enable_thinking=False disables it, and low_effort=True shortens enabled thinking. These are checkpoint template controls, not a low/medium/high API menu. Previous reasoning is stripped by default. IBM recommends temperature=1.0/top_p=0.95; example max_new_tokens values are not hard output caps. Check runtime memory requirements for this checkpoint size. Scores from other Granite sizes and publisher estimates do not transfer.

What is IBM Granite 4.2 30B's context window?
IBM Granite 4.2 30B accepts about 131K 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 30B best for?
IBM Granite 4.2 30B is a balanced tier from IBM. It suits self-hosted enterprise text, coding and tool use, multilingual workloads. Thinking is enabled by default; enable_thinking=False disables it, and low_effort=True shortens enabled thinking. These are checkpoint template controls, not a low/medium/high API menu. Previous reasoning is stripped by default. IBM recommends temperature=1.0/top_p=0.95; example max_new_tokens values are not hard output caps. Check runtime memory requirements for this checkpoint size. Scores from other Granite sizes and publisher estimates do not transfer.
Can I self-host IBM Granite 4.2 30B?
IBM Granite 4.2 30B 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.
