10 guides rebuilt, 1500+ words each

September 28, 2026 · ~4 min read

Hey, here’s VelsTech Weekly #6 – the rebuild issue.

I spent the week hardening the 10 guides that matter most – every one now 1500+ words with lab-tested numbers from my RX 6800M, failure modes I actually hit, visible FAQs, and linked sources. No new topics, just the core funnel made trustworthy: start here → VRAM → GPU → cost.

🚀 The funnel, rebuilt

1. Start: run your first model in 5 minutes
Ollama setup plus the verify-install checks (disk, GPU visibility, port-11434 fix), what good speeds look like, and a privacy checklist with offline test.
Getting started →

2. VRAM: the 30-second math + KV tables to 262K
Worked 14B example, context-length KV table (dense + 35B MoE), MoE exception, and an OOM troubleshooting checklist.
VRAM guide →

3. GPU: lab-tested picks with failure notes
Qwen 27B 18–22 tok/s partial-offload data, 35B MoE at 262K, used-3090 thermal/BIOS checks, and PSU rules that prevent token garbage.
GPU guide →

4. Cost: break-even + Opus 5.5 placement
Payback windows (Sonnet <1 mo, DeepSeek ~6 mo), India slab notes, hidden costs (retries, review time), and when cloud still wins.
Cost comparison →
