Before It Codes: Catching Qwen3.5-4B Planning With J-Lens
I used Anthropic's new Jacobian lens to test whether Qwen3.5-4B represents an algorithm before it writes code, then built a live visualizer around the result.

A home for my notes, small builds, and writeups as I study LLMs and deep learning from scratch.
Hybrid Token-Efficient Routing Agent
How I built TOKENMAN for AMD Developer Hackathon ACT II: a deterministic, local-model, and Fireworks routing agent that climbed from 6,101 counted tokens to zero.

[ICML ’26 Effort] Efficient Qwen: Making Qwen3.5-4B Faster on a Single A10G
My ICML 2026 AdaptFM effort to optimize Qwen3.5-4B for low-latency inference on a single NVIDIA A10G through 100+ runtime, compiler, and quantization experiments.

Looking Inside Qwen3-4B With Sparse Autoencoders
I trained a sparse autoencoder on Qwen3-4B-Base, labeled its learned features, and tested one by steering the model toward cooking instructions.

Pre-Training My First Base Language Model From Scratch
Took a model from random initialization through 2B tokens of FineWeb-Edu on a single H100 and watched it learn next-token prediction from nothing.

Parameter Golf: My OpenAI Model Craft Experiment
I didn't come close to the Parameter Golf leaderboard, but I still had a lot of fun running scattered H100 experiments on Modal, hunting tiny BPB improvements while watching ideas collapse against artifact size limits, and figuring out the hard way why squeezing a capable model into 16 MB is trickier than it sounds.

My First Successful RL Training Run With OpenEnv And Wordle
A full fine-tune of Qwen3-1.7B on Wordle using OpenEnv, with a reward curve that actually went up and shaped rewards that taught real gameplay behavior.

My Second RL Experiment On Prime Intellect Lab
My second RL experiment while studying GRPO: moving to Prime Intellect Lab, testing smaller and larger setups, and finally getting a reward curve that went up.

First RL Experimental Project: RLVR Using GRPO With TRL On Modal
My first ever RL experiment: RLVR on GSM8K using Hugging Face TRL, Qwen2.5 1.5B Instruct, and an NVIDIA H100 on Modal, with notes on where the reward function broke and what I want to fix in v2.

Teaching a 3B Base Model to Emit Reasoning Traces
A first small-scale AI research experiment: cold-start SFT on Nanbeige4-3B-Base using 2,160 distilled reasoning triplets, trained with LoRA on an H100, with notes on what worked and what I want to try next.
