IBM's open-weight Granite 4 models deliver enterprise-grade reasoning with a 128K context and permissive Apache 2.0 licensing.
Granite 4 is IBM's fourth-generation open language model family, tuned for instruction following, RAG, and agentic workflows. The series ships in dense and mixture-of-experts variants, all under Apache 2.0, which makes it a favorite for regulated industries that need auditability and self-hosting.
Who it's for: Enterprises, government teams, and developers who need a fully auditable, self-hostable LLM with strong reasoning and long-context support.
Process entire codebases or long legal documents in a single pass without chunking artifacts.
No usage restrictions or field-of-use limitations — deploy commercially with full indemnification from IBM.
Optimized weights run on vLLM for production or Ollama for local prototyping with minimal config.
Built-in alignment and content-filtering hooks reduce the amount of custom safety middleware you need.
Granite 4 is the pragmatic choice when compliance, auditability, and self-hosting matter more than chasing leaderboard scores.
