I spent $35 turning a Qwen3-4B model into a foul-mouthed friend named Monty.
The hard parts of fine-tuning were nothing I expected.
Five things I learned 🧵
5/ A system prompt on the vanilla model gets you ~70% of the surface behaviour.
But it still answered like a Stack Overflow reply with a swearing dictionary attached. Fine-tuning is what changes the shape of what the model produces.
As soon as you have everything figured out, things change.
Competitors, alternatives, employees, customers, the economy, epidemics, and other things whose identities are also unpredictable.
So you can never stop talking to customers or rethinking strategy.
Ordered numbers are so effective for DB indexes. Not sure why time-ordered, high-performance 64-bit Snowflake IDs aren't widely used for non-public identifiers and instead the preference is for 128-bit UUIDs. Convenience?

Build human-like memory for your Agents (open-source)!
Every agentic and RAG system struggles with real-time knowledge updates and fast data retrieval.
Zep solves these issues with its continuously evolving and temporally-aware Knowledge Graph.
Like humans, Zep organizes an Agent's memories into episodes, extracts entities and their relationships from these episodes, and stores them in a knowledge graph:
(refer to the image below as you read)
1) Episode Subgraph: Captures raw data with timestamps, retaining every detail for easy historical lookup.
2) Semantic Entity Subgraph: Extracts entities (e.g., “Alice,” “Google”) and facts (“Alice works at Google”). Everything is versioned, so outdated info gets replaced.
3) Community Subgraph: Groups related entities into clusters, with summaries for faster retrieval.
Zep delivers up to 18.5% higher accuracy with 90% lower latency when compared to tools like MemGPT.
It's fully open-source!
It’s true that you can outwork someone else who has more talent, and still win.
But there are competitors with both talent and hard work.
To beat 𝘵𝘩𝘦𝘮, you have to be uniquely yourself, so that it’s no longer about “them” at all.

You're never "ready," so start today.
You’re never “finished,” so ship today.
You’re never “perfect,” so enjoy today.
And the student was enlightened.
