> Model T to 2026 Camry was an amazing shift without really changing the combustion engine.

A lot of times the big jumps in internal combustion engine development have been down to materials science or manufacturing capability improvement.

The underlying thermodynamics and theoretical limits have not changed, but the individual parts and what we make it out of have steadily improved over time.

The other factor to this is the need for emissions reduction strategies as a overriding design factor.

The analogue to these two in LLMs are:

1. The harnesses and agentic systems-focused training has gotten better over time so performance has increased without a step change in the foundation models.

2. The requirements for guardrails and anti-prompt injection and other concepts to make LLMs palatable for use by consumers and businesses.
