Temperature
A setting in AI tools that controls how predictable or creative the output is. Lower temperature (0.0-0.3) produces more consistent, focused output, better for clinical documentation. Higher temperature (0.7-1.0) produces more varied, creative output, potentially useful for brainstorming therapy materials, but riskier for accuracy.
A parameter in language model inference that scales the probability distribution over the vocabulary before sampling. Temperature = 0 selects the highest-probability token (greedy decoding); higher values flatten the distribution, increasing randomness and diversity in output.
Why SLPs Need to Know This
If you’re using a tool like ChatGPT, Claude, or Gemini, temperature may be adjustable in settings. Choosing the wrong temperature for your task can mean the difference between a reliable clinical document and a creative but unreliable one.
Practical Guide for SLPs
| Temperature | Best For | Avoid For |
|---|---|---|
| Low (0.0–0.3) | Progress notes, eval reports, goal writing, compliance documentation | Brainstorming, generating novel therapy ideas |
| Medium (0.4–0.6) | Parent communication, education handouts, therapy activity descriptions | Legal documents, standardized report sections |
| High (0.7–1.0) | Brainstorming therapy activities, generating story starters, creative materials | Any clinical documentation, anything going into a record |
The Clinical Analogy
Think of temperature like the difference between a structured assessment and a dynamic assessment. Low temperature is the standardized test: predictable, reliable, narrow. High temperature is the dynamic assessment: flexible, exploratory, but harder to replicate. You wouldn’t use a dynamic assessment format for an eligibility report, and you shouldn’t use high temperature for clinical documentation.
