## The takeaways#
- 01 The model is the trained engine behind an AI capability.- 02 Training adjusts a model's internal parameters so it can recognise and generate patterns.- 03 Model capability and product capability are related but not identical.- 04 Evaluate a model using representative work, not a single impressive demo.- Reader I used the same prompt in two tools. Why was one answer much better? Robot They may use different AI models, each trained and designed with different strengths. Takeaway: The model is the trained engine behind an AI capability.- Reader What is inside a model? Robot It contains many learned parameters that shape how input becomes a predicted output. Takeaway: Training adjusts a model's internal parameters so it can recognise and generate patterns.- Reader So the model controls everything the app can do? Robot No. The product can add tools, context, permissions, and guardrails around the model. Takeaway: Model capability and product capability are related but not identical.
- Reader I will test models on my real tasks instead of choosing only by popularity. Robot Exactly. The best model is the one that meets your actual requirements. Takeaway: Evaluate a model using representative work, not a single impressive demo.
