Granite 4.1 LLMs: How They’re Built

An in-depth technical walkthrough of data engineering, pre-training, supervised fine-tuning, and reinforcement learning behind the Granite 4.1 LLMs. Authors: Granite Team, IBM TL;DR — Granite 4.1 is a family of dense, decoder‑only LLMs (3B, 8B, and 30B) trained on ~15T tokens using a multi‑stage pre‑training pipeline, including long‑context extension of up to 512K tokens. The models are further refined with supervised fine‑tuning on ~4.1M high‑quality curated samples and reinforcement learning via on‑policy GRPO with DAPO loss (Yu et al., 2025). […]

AI evals are becoming the new compute bottleneck

Summary. AI evaluation has crossed a cost threshold that changes who can do it. The Holistic Agent Leaderboard (HAL) recently spent about $40,000 to run 21,730 agent rollouts across 9 models and 9 benchmarks. A single GAIA run on a frontier model can cost $2,829 before caching. Exgentic‘s $22,000 sweep across agent configurations found a 33× cost spread on identical tasks, isolating scaffold choice as a first-order cost driver, and UK-AISI recently scaled agentic steps into the millions to study […]
