IBM also published FP8, FP4, and GGUF variants for local and server deployment.
Why it matters: The release makes a full agent-training recipe and usable small-to-mid-sized checkpoints inspectable together. Teams can test whether agentic post-training, context controls, and quantization improve their own workflows without depending on a closed model…
