A Temperature (Language Model) Parameter is a large language model writing parameter that can be used to configure text generation systems that support natural language generation.
- AKA: Sampling Temperature, Temperature Scaling Parameter.
- Context:
- It can adjust the probability distribution of next-token predictions, influencing the balance between deterministic and diverse outputs.
- It can control the model's creativity and variability by modulating the likelihood of selecting less probable tokens.
- It can impact the coherence and novelty of generated text, with lower temperatures favoring predictability and higher temperatures encouraging exploration.
- It can be set within a range (e.g., 0.0 to 2.0) to tailor the model's responses to specific applications, such as factual accuracy or creative writing.
- It can influence the trade-off between repetition and originality in the model's output.
- It can be combined with other parameters like Top-k Sampling or Top-p Sampling to fine-tune text generation strategies.
- It can range from being a fixed value to being dynamically adjusted based on the context or desired outcome.

- Example(s):
- Setting the temperature to 0.2 in an LLM to generate precise and consistent answers for technical documentation.
- Adjusting the temperature to 1.0 to balance coherence and creativity in storytelling applications.
- Increasing the temperature to 1.5 to encourage novel and diverse responses in brainstorming sessions.
- ...
- Counter-Example(s):
- Using a fixed, default temperature without considering the specific requirements of the task, leading to suboptimal outputs.
- Neglecting to adjust the temperature parameter when switching between tasks that require different levels of creativity or precision.
- Assuming that a higher temperature always results in better quality text generation, without evaluating the coherence of the output.
- Tone Setting Parameter, which can set formality to "strict" for formal documents.
- Length Control Parameter, which restricts the number of words to be generated.
- Citation Style Parameter, which sets the citation type.
