|

|
||||
### Temperature
|
||||
Primary factor to control randomness of outputs. 0 = deterministic (only the most likely token is used). Higher value = more randomness.
|
||||
### top_p
|
||||
If not set to 1, select tokens with probabilities adding up to less than this number. Higher value = higher range of possible random results.
|
||||
### top_k
|
||||
Similar to top_p, but select instead only the top_k most likely tokens. Higher value = higher range of possible random results.
|
||||
### typical_p
|
||||
If not set to 1, select only tokens that are at least this much more likely to appear than random tokens, given the prior text.
|
||||
### epsilon_cutoff
|
||||
In units of 1e-4; a reasonable value is 3. This sets a probability floor below which tokens are excluded from being sampled. Should be used with top_p, top_k, and eta_cutoff set to 0.
|
||||
### eta_cutoff
|
||||
In units of 1e-4; a reasonable value is 3. Should be used with top_p, top_k, and epsilon_cutoff set to 0.
|
||||
### repetition_penalty
|
||||
Exponential penalty factor for repeating prior tokens. 1 means no penalty, higher value = less repetition, lower value = more repetition.
|
||||
### repetition_penalty_range
|
||||
The number of most recent tokens to consider for repetition penalty. 0 makes all tokens be used.
|
||||
### encoder_repetition_penalty
|
||||
Also known as the "Hallucinations filter". Used to penalize tokens that are *not* in the prior text. Higher value = more likely to stay in context, lower value = more likely to diverge.
|
||||
### no_repeat_ngram_size
|
||||
If not set to 0, specifies the length of token sets that are completely blocked from repeating at all. Higher values = blocks larger phrases, lower values = blocks words or letters from repeating. Only 0 or high values are a good idea in most cases.
|
||||
### min_length
|
||||
Minimum generation length in tokens.
|
||||
### penalty_alpha
|
||||
Contrastive Search is enabled by setting this to greater than zero and unchecking "do_sample". It should be used with a low value of top_k, for instance, top_k = 4.
