This paper shows that you can predict actual purchase intent (90% accuracy) by asking an LLM to impersonate a customer with a demographic profile, giving it a product & having it give its impressions, which another AI rates. No fine-tuning or training & beats classic ML methods.

Build Autograd Engine, Mini-GPT, and LoRA Fine-tuning From Scratch
By
–
– build an autograd engine from scratch
– write a mini-GPT from scratch
– implement LoRA and fine-tune a model on real data
– hate CUDA at least once
– cry
– keep going the roadmap – 5 phases
– if you already know something? skip
– if you're lost? rewatch
– if you’re stuck? use -

DeepThink IMO Gold Model Achieves State-of-the-Art FrontierMath Results
By
–
Very cool to see this new state-of-the-art result on FrontierMath achieved by the #DeepThink IMO Gold model that we built 3 months (a long time) ago 🙂 The fact that is evaluated externally using a publicly available API is a strong testament that what we built generalizes beyond

Multiple RL Trajectories Improve Agent Strategy Diversity
By
–
We have always been using 1 RL trajectory for training. Why not use more? In this research: Polychromic Objectives for RL, they train their model on sets of trajectories and reward both success & diversity, so the agent keeps MULTIPLE strategies alive all at once.

interesting, if it is a DLM why does it seem to decode sequentially?
