#What are the parameters?

Temperature:
This parameter controls how random or creative the AI's responses are. Lower values (like 0.1) make the AI more focused and deterministic, while higher values (like 1.0) make it more random and creative. Imagine it like the AI's "willingness to take risks" when generating text.
Repetition Penalty:
This is a measure used to avoid the AI repeating the same words or phrases. A higher repetition penalty means the AI will try harder to avoid saying the same thing over and over. It helps make the responses more varied and interesting.
Frequency Penalty:
This parameter reduces the likelihood of the AI using the same word multiple times within a short span. It's like gently nudging the AI to use a wider vocabulary, making the text more diverse and less repetitive.
TopP (Nucleus Sampling):
TopP controls the randomness of the AI's response by limiting the pool of words it considers. Instead of picking from the entire vocabulary, it only considers the top words that add up to a probability of P. For example, if TopP is 0.9, the AI only looks at the top 90% of probable words, ignoring the less likely ones. This helps balance between making sensible and creative choices.
TopK:
This parameter limits the AI to consider only the top K most likely words for each step of text generation. If TopK is 50, the AI will only choose from the 50 most probable next words. It ensures that the AI picks from a high-probability set, balancing creativity and coherence.
Min Length:
This sets the minimum length of the generated text. It ensures that the AI's response isn't too short and provides enough information or context in its replies. For instance, if Min Length is 50, the AI will generate at least 50 tokens (words or pieces of words).
Max New Tokens:
This is the maximum number of tokens the AI is allowed to generate in one go. It prevents the AI from creating overly long responses. If Max New Tokens is 100, the AI will stop generating after 100 tokens, ensuring concise outputs.
Context Size:
Context size refers to the maximum amount of previous text the AI can consider when generating new text. Think of it as the AI's memory span. If the context size is 2048 tokens, the AI can look back at up to 2048 tokens of text to understand the context and generate a relevant response.
In summary:
- Temperature: Creativity level.
- Repetition Penalty: Avoids repetition.
- Frequency Penalty: Encourages varied vocabulary.
- TopP: Limits to top probable words.
- TopK: Limits to a set number of top words.
- Min Length: Ensures minimum text length.
- Max New Tokens: Limits maximum text length.
- Context Size: Memory span for previous text.
