Analysis Summary

Granite 4.0 H 1B is IBM's 1B hybrid Granite model, released October 2025. With an intelligence index of 2.7 and MMLU-Pro of 27.7%, it sits just above the 350M variant but remains in the very low capability tier. LiveCodeBench at 11.5% and agentic index at 19.6 show modest improvements, and LCR at 0.06 is negligible. IFBench at 0.26 is limited for instruction-following tasks.

For businesses, this model is appropriate only for edge or embedded deployments where model size is the primary constraint. It is not suitable for production reasoning, coding, or content workflows. The hybrid architecture may offer efficiency advantages in specific inference environments.

Teams with strict on-device constraints may find it marginally more capable than the 350M variant, but for any meaningful business application, a model with a substantially higher intelligence index is required.
