Tom Tunguz called it localmaxxing. I run a 3070 + 5070 Ti + 5090 in one box and serve Llama 3.1 8B locally every day. Here are the real tokens-per-second, the real watts, and the real cost per million tokens.
SaaStr data shows enterprise AI share shifting hard toward Claude. The lesson isn't pick Claude. It's stop hard-coding one vendor.
AI-native software is shipping at roughly 17% gross margins while traditional SaaS sits near 70%. The token bill ate the unit economics. Here's what's actually broken and how to claw margin back.
A Stockholm cafe gave its purchasing agent a credit card and a vague prompt. $21,000 later it owned 6,000 napkins and no bread. Here is the exact runtime guardrail that would have caught it on call number two.
The May 14 autotrader review is done. The account is up 7.7% before compute, still negative after compute, and still lagging SPY and BTC. Decision: keep V2 paper-only, add no new live money, and revisit after the next scorecard.
I spent the week tightening the AgentGuard release path, shipping proof-heavy docs and perf fixes, and keeping the benchmark gap visible instead of hand-waving it away.
Closed loops shipped, the funnel got narrower, and the weekly scoreboard got more honest.
Short answer: Q4_K_M wins for most local LLMs — 75% smaller with near-zero quality loss. Q5, Q6 and Q8 each win edge cases. Benchmarked on real GPUs — here's the pick for your VRAM. (2026)
Agent skills are becoming a distribution layer for developer tools. The practical move is one source package that can show up in PyPI, Claude-style skills, and skills.sh.
April 2026 made one thing clear: chat subscriptions are best-effort tools. Builders need API-level budgets, rate limits, and kill switches when the work matters.
Reflex.dev measured a 45x token cost gap between computer-use agents and structured APIs for the same task. Here's why, and the decision rule that keeps your bill sane.
PocketOS lost their production database backups to a Cursor agent. Here's what runtime spend rails actually catch, what they don't, and the layered defense your agents need before production.
A 1,764-app audit found 7% had open Supabase databases and 15% of Bolt apps had hardcoded secrets. The fix takes ten minutes.
No metering, no per-team caps, no dashboards. Uber spent its entire 2026 AI budget on Claude Code in just 4 months. The 5-step pattern behind every runaway AI bill — and the fix that stops it.
I need my agent to do X. Skill or MCP? A short decision rule with worked examples for small-business agent builders.
Before you ship an AI agent for a client, prove budget caps, loop detection, alert proof, remote kill, and retained incident history.
