I spent $5,000 on API tokens — here's what I built with AI

$5,000 in AI Credits: A System Inventory In one month, spending roughly $5,000 on AI subscriptions and APIs (Claude Pro + Claude API + OpenAI API + Copilot Pro+ + Codex + Paseo + miscellaneous), I built out 18 major systems independently, with a total codebase of roughly 50,000+ lines of code (excluding auto-generated AI scripts). For comparison: the same functionality, developed from scratch by 2 full-stack engineers, would conservatively take 6-12 months and cost at least ¥300,000-600,000. ...

OpenClaw + GitHub Copilot + Claude Opus 4.6 parameter tuning log

Running OpenClaw with default config will hit two problems after a while: quota burns too fast and long sessions crash from timeouts. This post logs 8 parameters I actually tuned, and the reasoning behind each. Architecture First Here’s my setup: GitHub Copilot Pro+: $19/month, 1500 premium requests/month quota Claude Opus 4.6: accessed via Copilot’s model routing, model ID github-copilot/claude-opus-4.6 OpenClaw: handles Telegram interactions, Skill calls, scheduled tasks Quota math: each AI assistant reply = 1 premium request (including replies after tool calls). 1500 sounds like plenty, but without optimization it dries up fast. ...
