Briefings

A SWE and hobbyist researcher argues that frontier LLMs have not significantly improved 'raw intelligence' despite overall performance gains. Key findings include: production harnesses rarely improved results when switching to newer models due to context engineering and tool limitations; software engineering improvements are more dependent on senior engineer review than model capability; local models show strong performance without proportional parameter advantages. The author attributes recent progress to cumulative improvements and better tooling rather than exponential jumps in reasoning ability.

Key points

• Production harnesses rarely improved results when switching to newer frontier models because context engineering and inadequate tools were the primary failure points.
• Software engineering improvements are more dependent on senior engineer review and correction than on the inherent capability of the frontier model itself.

Context

The researcher works as a SWE and hobbyist, integrating AI into products by building custom harnesses for context retrieval, prompts, and tools. Their analysis compares these practical constraints against theoretical 'raw intelligence' improvements, suggesting the latter may not be the primary driver of recent AI progress.

Limitations

Evidence is limited to personal observations from a single user perspective; specific numbers or dates are not provided. The author explicitly states that their observations do not prove intelligence needs few parameters or that progress has stalled, leaving the validity of these claims uncertain.
