I love this. I started putting together the notes for what became The Craft of Post-Training about a year ago. I didn't remotely foresee how post-training will capture the cultural zeitgeist (@nostarch did, though!). And now we have Hot Post-Training Autumn. We're so back.
Introducing River Recipes: our open-source initiative for turning promising research into vetted, reproducible training recipes. Our first recipe tackles text-to-SQL, where our trained open models beat GPT-6 Astra Pro and Claude Opus 5.5 on Arcwise-Plat for less than 1% of the cost. Read the full breakdown and explore the recipe ↓ river.ai/achieving-frontier-…
