LESSON 2/8 — Tiered model routing beats one-model-for-everything
Anthropic just shipped Fable 5.
The reflex: route everything through it.
Don't.
A better model raises the ceiling on your reasoning step. It does nothing for extraction and cleanup — except cost more.
Swap it in where judgement lives. Leave the cheap model on the grunt work.
New models test whether you own your stack, or it owns you.
Lesson 1/8: If you can't swap your AI provider in an afternoon, you don't own your AI stack.
The day a client asks "can you guarantee our data never leaves our infrastructure?" — provider lock-in turns a config change into a months-long rewrite.
Build the seam early:
• LLMProvider interface
• VectorStore interface
Sovereignty starts here.
I build AI systems that run in production — not slides about AI.
Starting a series: 8 engineering lessons from shipping real LLM systems. Patterns, tradeoffs, the stuff that breaks at 2am.
Written for builders and for anyone deciding how their org should adopt AI.
First one drops shortly.
Why did I build a tracker for the BRVM?
Because tracking the West African stock market in 2026 is still way too hard.
- No public API
- Data scattered across multiple sources
- No modern, free tool for investors
So I decided to fix it myself:
- Real-time dashboard built with modern framework
- Sector-by-sector analysis
- AI-powered market insights with daily alerts
- Portfolio import & tracking
- Doli AI chatbot — ask anything about the BRVM
- 100% free
The result -> https://t.co/Pjk0qXHg93
