# Procedural prompting degrades performance on frontier models

## Claim

Providing step-by-step procedural instructions (the 'how') to highly capable models like [[concept-claude-mythos|Claude Mythos]] *constrains* their performance. Their superior reasoning can find more efficient solutions when not forced down a human-prescribed path.

## Confidence

**Speaker confidence: high.** External validation: **partial** — the underlying [[concept-bitter-lesson-llms|Bitter Lesson]] principle (Sutton 2009) is well-grounded; specific application to GB300-class models is not yet testable since no such model is publicly released.

## How to test it

Run identical tasks through a frontier model (e.g., Claude 3.5 Sonnet, o1-preview, GPT-4o) using:
1. A highly detailed procedural prompt
2. A purely [[concept-outcome-driven-prompting|outcome-driven prompt]]

Measure:
- Task quality (rubric-based eval)
- Latency
- Token consumption
- Solution diversity

## Existing evidence

Mixed across current frontiers:
- **Procedural helps novices**, especially on multi-step planning (Chain-of-Thought, Wei 2022).
- **Procedural constrains experts** — Anthropic's own guides note over-specification can suppress better solutions.
- **Tree-of-Thoughts** shows structured scaffolding still wins on hard planning, suggesting the curve plateaus rather than reverses.

## Implication

If supported empirically on GB300-class models, this claim is the foundation for [[action-delete-procedural-prompts]] and the [[framework-mythos-readiness|Mythos Readiness Transformation]]. See [[contrarian-complex-prompting-antipattern]] for the speaker's strongest framing.
