Summary

Granite 4.2 is available in 3B, 8B and 30B sizes, with IBM describing native thinking and agentic reinforcement learning for multi-step enterprise tasks. The release also includes lightweight Granite Speech 5.0 Turbo CTC models intended for fast transcription on edge devices.

Why it matters

The release strengthens the open-weight alternative for organisations that need smaller, deployable reasoning models rather than relying exclusively on frontier-scale hosted systems.
