Research notes on AI infrastructure, LLM serving, and autonomous agents. Things that took too long to figure out, written down so you don't have to.

runs all kinds of models at home — LLMs, image gen, video gen, then writes down what he figures out
quantizes models to FP8 / NVFP4 and ships them on Hugging Face — people actually run them
builds options-trading infrastructure with AI agents
had a spec-decode fix merged into vLLM's speculators
occasionally ships iOS apps

- 2026-06-16[Agent 101 #1] AI assistant vs ChatGPT: one answers you, one uses your tools to get things done
You mostly use ChatGPT one question at a time. A self-hosted AI assistant (agent) finishes the job with your own tools, runs on your side, and plugs into the apps you use daily. Lesson one of building your own assistant from zero.
- 2026-06-16[Agent 101 #4] How to install Hermes Agent Desktop: your first AI assistant, no terminal
Install the Hermes Agent desktop app — no terminal. Download it, let it auto-install dependencies, sign in with your ChatGPT account, and your first AI assistant is running in about 15 minutes.
- 2026-06-12[Local LLM #1] My first Q2 model looked broken on a 128GB box — the real culprit was a parser that couldn't read DSML, not the quantization
DeepSeek-V4-Flash is 284B. I got it onto a single 128GB GB10 with antirez's ds4 engine and an asymmetric Q2 GGUF at 15.6 tok/s. The fun part: the broken tool calls weren't the 2-bit quant's fault. The runtime just couldn't parse DSML.
- 2026-06-11[Benchmark #2] Qwen3.5-122B on DGX Spark — 2× faster
Qwen3.5-122B-A10B tops out at 17 tok/s on a 128GB DGX Spark — the GDN wall in vLLM won't budge, not even with a merged perf PR. I swapped vLLM for the Atlas engine on the same abliterated NVFP4 weights and the throughput doubled to 33.9 tok/s (36.5 with MTP, ~2×), uncensored behavior intact. The real lever was outside the quant toolbox.

- 2026-05-23[LLM 101 #7] How to spot AI hallucinations — three red flags before you verify
AI delivers wrong answers in the same confident tone as right ones. Three red flags to catch it early — impossible numbers, suspiciously specific details, answers that shift on a re-ask — plus a case where ChatGPT gave me a +205% P&L that can't exist.
- 2026-04-17[LLM 101 #6] Why Run AI on Your Own Computer? It's Not a Cheaper ChatGPT — It's a Different Tool
Local AI isn't a budget ChatGPT. It's a knowledge extractor, private code assistant, and offline tool. Monthly power cost ~$1.20 vs ChatGPT Plus $20. This guide has a decision table for when to use which.

AI is strong, but four things still trip it up in 2026: hallucinations, stale knowledge, short memory, and privacy defaults. Even Anthropic's own lawyers got caught by the first one.

The first answer AI gives you is a rough draft, not the final answer. Learn 5 follow-up techniques — adding constraints, asking for comparisons, and letting AI ask YOU questions — to get dramatically better results.

AI forgets what you said 20 messages ago. It's not broken — its desk is full. This guide explains context windows, why conversations go stale, and how to work around the limit.

- 2026-07-03[Just for Fun — Advanced #8] I Doubled My Agent's Decode Speed and It Got Slower: TTFT Is the Number You Actually Feel
I swapped my home agent's brain for one that decodes 30-40 tok/s instead of 14, and it felt slower. The number I'd stared at for a year — tok/s — only measures how fast tokens come out, not how long before they start. On a hybrid model, a single cache miss re-prefills the entire prompt: same box, same brain, 2.6s warm vs 216s cold. Here's the live log.
- 2026-07-02[Just for Fun — Advanced #7] Progressive Streaming on a Slow Model Got My Bot Rate-Limited by Telegram
To ease the wait on a pokey local agent, I turned on Telegram streaming — which, the way this bot did it, means rewriting the same message every fraction of a second. On a 14 tok/s brain, a single 175-second reply works out to an estimated couple hundred edit requests, which slammed into Telegram's flood control and got the whole bot benched for four minutes — final answer included. The short, ugly lesson: slow models should not fake streaming with edits. Send the finished answer once. Live logs inside.
- 2026-07-01[Agent 101 #15] Hermes /learn: I had a local 27B write its own reusable skill
Hermes has a /learn command that turns 'something you just did' into a reusable skill — a SKILL.md. I wired it into my own fleet: one Kanban card, a local 27B running on a modded 2080 Ti, and about 3 minutes later it handed back a clean, spec-compliant skill — plus two implementation details the docs don't spell out (slash command vs. dispatch, and where skills actually live). A plain-language walkthrough of what /learn does, how to use it, and where its limits are.
- 2026-06-29[Agent 101 #14] One spec, three assistants, three Tetris games: a Hermes Kanban dispatch test
After raising a fleet of assistants, I gave them the same one-line 'make a Tetris game' spec — no details at all — one card each, and let them each write a web Tetris in a single shot. I touched zero lines of game code; I only published the result. The surprise: from that one line, the Hermes harness plus a local model I tuned myself (on a modded 2080 Ti) filled in things I never asked for — a ghost piece and wall-kick — in one shot. You can play all three.
- 2026-06-29[Troubleshooting #1] HuggingFace download stuck at 0 bytes on Windows — Xet, Python 3.13, ai-toolkit
Training with ai-toolkit on Windows + RTX 5090 hit three walls before it even started: Python 3.13 dependency hell, a HuggingFace download frozen at 0 bytes, and ssh killing the process. Each one's error pointed the wrong way — diagnosis and fix for all three.
