Granite 4.0 H 1B
Analysis Summary
Granite 4.0 H 1B is IBM's one-billion-parameter hybrid model released in October 2025. The record includes measurements for reasoning, mathematics, coding, instruction following, long-context handling, terminal use, and tool-oriented behavior. Performance is limited across these areas, although its instruction-following result is somewhat stronger than its general reasoning and coding results. Pricing and deployment characteristics are not provided.
It could handle narrowly defined extraction or classification tasks when outputs are checked by rules. It is not suitable for autonomous agents, client-facing copy, complex SEO work, code generation, or analysis of large documents. The compact size may appeal to constrained deployments, but the available data does not establish throughput or cost benefits. Use it only after task-specific validation, and prefer a stronger small model for any workflow where errors create client or operational risk.
