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 — 770K+ downloads so far
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.
- 2026-04-16[Ask AI Right #7] What AI Does Poorly — Four Landmines to Know Before Using ChatGPT or Claude in 2026
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.
- 2026-04-14[Ask AI Right #6] The Art of Follow-Up Questions — What to Do When the First Answer Is Too Shallow
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.
- 2026-04-14[LLM 101 #5] Context Window — How Much Can AI Read at Once?
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.

- 2026-11-04[DGX Spark #51] DGX Spark and GX10 prices in Taiwan: up 80% in a year, flat since August
GB10 prices in Taiwan, Nov 2025 to Nov 2026: ASUS GX10, MSI EdgeXpert and DGX Spark up 47-80%. Cheapest ways to buy, the 64GB model, RTX Spark vs GB10.
- 2026-11-04[AI Workflow #29] Teaching a Chinese TTS Taiwan Mandarin: a 3-to-80-Entry Lexicon Plus g2pW Auto-Tagging
VoxCPM2 read Taiwan Mandarin with mainland readings. A shared lexicon (3 to 80 entries), g2pW auto-tags and a few text rules fixed it before the TTS.
- 2026-11-04[Benchmark #28] Idol Image-to-3D on a Modded RTX 2080 Ti: Fix the cuDNN Crash, 84.8 s → 72.7 s
Idol turns one image into a 3D Gaussian splat. On a modded 2080 Ti 22GB the default run crashes; a one-line patch fixes it: 84.8 s → 72.7 s per image.
