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.
