    Not all parameters are used by all loaders. See [this page](https://github.com/oobabooga/text-generation-webui/blob/main/docs/Generation-parameters.md) for details.

    For a technical description of the parameters, the [transformers documentation](https://huggingface.co/docs/transformers/main_classes/text_generation#transformers.GenerationConfig) is a good reference.

    The best presets, according to the [Preset Arena](https://github.com/oobabooga/oobabooga.github.io/blob/main/arena/results.md) experiment, are:

    * Instruction following:
        1) Divine Intellect
        2) Big O
        3) simple-1
        4) Space Alien
        5) StarChat
        6) Titanic
        7) tfs-with-top-a
        8) Asterism

        2) Yara
        3) Shortwave

    ### 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.
