What's New in Mellea 0.4.0 + Granite Libraries Release

The release of Mellea 0.4.0 and the new Granite Libraries makes it easier to build structured, verifiable, and safety-aware AI workflows on IBM's Granite models. The open-source Mellea library replaces unpredictable prompting with maintainable AI programs, and this latest version introduces an "instruct-validate-repair" pattern and observability hooks. Instead of relying on a single large model, Granite Libraries are collections of specialized, fine-tuned adapters that excel at specific tasks like query rewriting or hallucination detection. This initial release includes three distinct libraries targeting core validation loops, various retrieval-augmented generation (RAG) tasks, and crucial safety and factuality checks.
