o3 is a research model
Sonnet 4 is an agentic model
Gemini 2.5 pro is a coding model
Gemini 2.0 flash lite is a RAG model
o4- mini is a task planning model
Deepseek r1 is a thinker model
GPT-4o is a chat model

These are all the AI models you need to care about.

Rest is fluff.

Reverse Engineering

If you’re starting with GIS software and coding, this is a faster way to learn.

You jump straight into real-world projects, break them apart, experiment with changes, and learn by doing.

Here's how;

Geospatial skills are in demand.

But standing out takes more than just knowing the basics.

- Many can map; few can innovate.
- Many use tools; few master them.
- Many automate; few build scalable solutions.

What's the difference between good and irreplaceable?

Let me break it down
