We’ve all had that moment where we watch a tutorial, nod along, but then realize we can’t actually do it ourselves because watching is just passive. At AIPrep, we are fixing this "watch and forget" cycle by building a foundational Generative Explanatory Model (GEM). GEM doesn't just give you a video or a wall of text; it builds an interactive lesson that asks you questions, catches your mistakes in real time, and adapts to your pace. We have just finished preparing our specialized datasets for this interactive logic, and you can already check them out on our profile to see how we are structuring this step-by-step reasoning. Training for the foundational model starts very soon, so stay in touch because something revolutionary is coming to the world of AI education. You can see our progress at aiprep.in.
Muon has gone from an experiment to a mainstream optimizer, but does it hold up for fine‑tuning? We ran head‑to‑head tests on Qwen3‑4B (10k+ high‑quality instruction rows) to find out.
Short story: Pure Muon converged fastest at the start, but its gradient‑norm spikes made training unstable. MuonClip (Kimi K2’s clipping) stabilizes long pretraining runs, yet in our small‑scale fine‑tune it underperformed, lower token accuracy and slower convergence. The winner was the hybrid: Muon for 2D layers + AdamW for 1D layers. It delivered the best balance of stability and final performance and even beat vanilla AdamW.
Takeaway: for small-scale fine-tuning, hybrid = practical and reliable.
Next Step: scale to larger models/datasets to see if Muon’s spikes become catastrophic or if clipping wins out.
