OPF Tone

Technical

Lead with the question or claim, then walk through the mechanism and the numbers. Use exact terminology; assume the audience can handle and prefers it. Diagrams, tables, and benchmarks are first-class.

Voice Cues

1
State the claim, then the mechanism, then the evidence.
2
Use exact terminology — don't soften technical terms for general readability.
3
Quote benchmarks with conditions (cold/warm, p50/p95/p99, dataset, hardware).
4
Prefer diagrams and tables over prose paragraphs for structural information.

Avoid

1
Vague claims ('much faster', 'better', 'easier').
2
Marketing framing without supporting data.
3
Glossing over caveats and tradeoffs.
4
Casual register that obscures precision.

Sample Phrases

“p95 inference latency is 38ms on a single A100, down from 312ms on the prior runtime.”
