Every fine-tune of my Minecraft NPC is served in NVFP4, because the box is limited by memory bandwidth, not compute. How the pipeline from fine-tune to served checkpoint works, and Clef as the first build I published.
Read moreClaude Code left out almost everything an IDE builds for a human, and that is why it works. What software looks like when the customer is an agent and the human is only watching.
Read moreA transformer paper, a Minecraft NPC that forgets where it put the crafting table, and what happened when I borrowed the paper's shape one level up.
Read moreRequirements gathering was insurance against expensive rework. Rework is cheap now, so I stopped buying it and let the requirements arrive as the decisions get smaller.
Read moreHow two steps back and a new base model actually made progress.
Read moreSpatial perception for language models is an open problem. My answer for Emil is a 48×35 text matrix, ray-marched from the world every turn — with a live view of the real thing.
Read moreSwapping the base model under my Minecraft NPC: three configuration mistakes worth 2.5x, a container that crash-looped 23 GiB nine times, and a context-window constant denominated in a unit that changes size when the model does.
Read moreThree checkpoints died because the chat template emptied every think block. The fourth, built to fix exactly that, learned to write 'Next: mine_block.' instead of thinking. The fifth was the fourth again.
Read moreWhy 'context doesn't fit' has to be recoverable state, and the six-stage ladder in my agent runtime that guarantees it.
Read moreFive papers, one design, one honest A/B: what speculative tool execution buys a 30B model on desk-sized hardware — and what it doesn't. Yet.
Read moreDebugging a fine-tuned agent with an agent in the loop: a wrong hypothesis, a fake 100%, and a train/serve mismatch found in the timestamps.
Read moreNo scripted policies, no behavior trees. A 30B model, a Rust body, a memory, and a data flywheel on one desk-sized machine.
