kobold

global kobold: KoboldLib

Methods:

Fields:

kobold.decode()

function KoboldLib.decode(tok: integer|table<integer, integer>) -> string

Callable from: anywhere

Decodes the given token or list of tokens using the current tokenizer. If kobold.backend is 'readonly' or 'api', the tokenizer used is the GPT-2 tokenizer, otherwise the model’s tokenizer is used. This function is the inverse of kobold.encode().

print(kobold.decode({15496, 2159}))  -- 'Hello World'

Parameters:

Returns:

kobold.encode()

function KoboldLib.encode(str: string) -> table<integer, integer>

Callable from: anywhere

Encodes the given string using the current tokenizer into an array of tokens. If kobold.backend is 'readonly' or 'api', the tokenizer used is the GPT-2 tokenizer, otherwise the model’s tokenizer is used. This function is the inverse of kobold.decode().

local tokens = kobold.encode("Hello World")
print(#tokens)  -- 2
print(tokens[1])  -- 15496
print(tokens[2])  -- 2159

Parameters:

Returns:

kobold.get_config_file()

function KoboldLib.get_config_file(clear?: boolean) -> file*

Callable from: anywhere

Returns a file handle representing your script’s configuration file, which is usually the file in the userscripts folder with the same filename as your script but with “.conf” appended at the end. This function throws an error on failure.

If the configuration file does not exist when this function is called, the configuration file will first be created as a new empty file.

If KoboldAI does not possess an open file handle to the configuration file, this function opens the file in w+b mode if the clear parameter is a truthy value, otherwise the file is opened in r+b mode. These are mostly the same – the file is opened in binary read-write mode and then seeked to the start of the file – except the former mode deletes the contents of the file prior to opening it and the latter mode does not.

If KoboldAI does possess an open file handle to the configuration file, that open file handle is returned without seeking or deleting the contents of the file. You can check if KoboldAI possesses an open file handle to the configuration file by using kobold.is_config_file_open.

local example_config = "return 'Hello World'"
local cfg
do
    -- If config file is empty, write example config
    local f <close> = kobold.get_config_file()
    f:seek("set")
    if f:read(1) == nil then f:write(example_config) end
    f:seek("set")

    -- Read config
    local err
    cfg, err = load(f:read("a"))
    if err ~= nil then error(err) end
    cfg = cfg()
end

Parameters:

Returns:

kobold.halt_generation()

function KoboldLib.halt_generation() -> nil

Callable from: anywhere

If called from an input modifier, prevents the user’s input from being sent to the model and skips directly to the output modifier.

If called from a generation modifier, stops generation after the current token is generated and then skips to the output modifier. In other words, if, when you call this function, kobold.generated has n columns, it will have exactly n+1 columns when the output modifier is called.

If called from an output modifier, has no effect.

kobold.restart_generation()

function KoboldLib.restart_generation(sequence?: integer) -> nil

Callable from: output modifier

After the current output is sent to the GUI, starts another generation using the empty string as the submission.

Whatever ends up being the output selected by the user or by the sequence parameter will be saved in kobold.feedback when the new generation begins.

Parameters:

kobold.authorsnote

field KoboldLib.authorsnote: string

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

The author’s note as set from the “Memory” button in the GUI.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

kobold.authorsnotetemplate

field KoboldLib.authorsnotetemplate: string

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

The author’s note template as set from the “Memory” button in the GUI.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

kobold.custmodpth

field KoboldLib.custmodpth: string

Readable from: anywhere
Writable from: nowhere

Path to a directory that the user chose either via the file dialog that appears when KoboldAI asks you to choose the path to your custom model or via the --path command-line flag.

If the user loaded a built-in model from the menu, this is instead the model ID of the model on Hugging Face’s model hub, such as “KoboldAI/GPT-Neo-2.7B-Picard” or “hakurei/lit-6B”.

kobold.feedback

field KoboldLib.feedback: string?

Readable from: anywhere
Writable from: nowhere

If this is a repeat generation caused by kobold.restart_generation(), this will be a string containing the previous output. If not, this will be nil.

kobold.generated

field KoboldLib.generated: table<integer, table<integer, integer>>?

Readable from: generation modifier and output modifier, but only if kobold.modelbackend is not 'api' or 'readonly'
Writable from: generation modifier

Two-dimensional array of tokens generated thus far. Each row represents one sequence, each column one token.

kobold.generated_cols

field KoboldLib.generated_cols: integer

Readable from: anywhere
Writable from: nowhere

Number of columns in kobold.generated. In other words, the number of tokens generated thus far, which is equal to the number of times that the generation modifier has been called, not including the current time if this is being read from a generation modifier.

If kobold.modelbackend is 'api' or 'readonly', this returns 0 instead.

kobold.generated_rows

field KoboldLib.generated_rows: integer

Readable from: anywhere
Writable from: nowhere

Number of rows in kobold.generated, equal to kobold.settings.numseqs.

kobold.is_config_file_open

field KoboldLib.is_config_file_open: boolean

Readable from: anywhere
Writable from: nowhere

Whether or not KoboldAI possesses an open file handle to your script’s configuration file. See kobold.get_config_file() for more details.

kobold.logits

field KoboldLib.logits: table<integer, table<integer, number>>?

Readable from: generation modifier, but only if kobold.modelbackend is not 'api' or 'readonly'
Writable from: generation modifier

Two-dimensional array of logits prior to being filtered by top-p sampling, etc. Each row represents one sequence, each column one of the tokens in the model’s vocabulary. The ith column represents the logit score of token i-1, so if you want to access the logit score of token 18435 (" Hello" with a leading space), you need to access column 18436. You may alter this two-dimensional array to encourage or deter certain tokens from appearing in the output in a stochastic manner.

Don’t modify this table unnecessarily unless you know what you are doing! The bias example scripts show how to use this feature properly.

kobold.logits_cols

field KoboldLib.logits_cols: integer

Readable from: anywhere
Writable from: nowhere

Number of columns in kobold.logits, equal to the vocabulary size of the current model. Most models based on GPT-2 (e.g. GPT-Neo and GPT-J) have a vocabulary size of 50257. GPT-J models in particular have a vocabulary size of 50400 instead, although GPT-J models aren’t trained to use the rightmost 143 tokens of the logits array.

If kobold.modelbackend is 'api' or 'readonly', this returns 0 instead.

kobold.logits_rows

field KoboldLib.logits_rows: integer

Readable from: anywhere
Writable from: nowhere

Number of rows in kobold.generated, equal to kobold.settings.numseqs. a local KoboldAI install.

kobold.memory

field KoboldLib.memory: string

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

The memory as set from the “Memory” button in the GUI.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

kobold.modelbackend

field KoboldLib.modelbackend: string

Readable from: anywhere
Writable from: nowhere

One of the following values:

kobold.modeltype

field KoboldLib.modeltype: string

Readable from: anywhere
Writable from: nowhere

One of the following values:

kobold.num_outputs

field KoboldLib.num_outputs: integer

Readable from: anywhere
Writable from: nowhere

Number of rows in kobold.outputs. This is equal to kobold.settings.numseqs unless you’re using a non-Colab third-party API such as OpenAI or InferKit, in which case this is 1. If you decide to write to kobold.settings.numseqs from an output modifier, this value remains unchanged.

kobold.outputs

field KoboldLib.outputs: table<integer, string>

Readable from: output modifier
Writable from: output modifier

Model output before applying output formatting. One row per “Gens Per Action”, unless you’re using OpenAI or InferKit, in which case this always has exactly one row.

kobold.settings

field KoboldLib.settings: KoboldSettings

Readable from: anywhere
Writable from: anywhere (does not affect other scripts when written to since each script has its own copy of this object)

Contains most of the settings. They have the same names as in gensettings.py, so the top-p value is kobold.settings.settopp.

All the settings can be read from anywhere and written from anywhere, except kobold.settings.numseqs which can only be written to from an input modifier or output modifier.

Modifying certain fields from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess. Currently, only the following fields and their aliases cause this to occur:

kobold.story

Readable from: anywhere
Writable from: nowhere

field KoboldLib.story: KoboldStory

Contains the chunks of the current story. Don’t use pairs or ipairs to iterate over the story chunks, use kobold.story:forward_iter() or kobold.story:reverse_iter(), which guarantee amortized worst-case iteration time complexity linear to the number of chunks in the story regardless of what the highest chunk number is.

You can index this object to get a story chunk (as a KoboldStoryChunk object) by its number, which is an integer. The prompt chunk, if it exists, is guaranteed to be chunk 0. Aside from that, the chunk numbers are not guaranteed to be contiguous or ordered in any way.

local prompt_chunk = kobold.story[0]  -- KoboldStoryChunk object referring to the prompt chunk

Methods:

kobold.story:forward_iter()

Callable from: anywhere

function KoboldStory:forward_iter() -> fun(): KoboldStoryChunk, table, nil

Returns a stateful iterator that efficiently iterates through story chunks from top to bottom.

for chunk in kobold.story:forward_iter() do
    print(chunk.num, chunk.content)
end

kobold.story:reverse_iter()

Callable from: anywhere

function KoboldStory:reverse_iter() -> fun(): KoboldStoryChunk, table, nil

Returns a stateful iterator that efficiently iterates through story chunks from bottom to top.

for chunk in kobold.story:reverse_iter() do
    print(chunk.num, chunk.content)
end

KoboldStoryChunk

Represents a story chunk.

Fields:

KoboldStoryChunk.content

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

field KoboldStoryChunk.content: string

The text inside of the story chunk.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

KoboldStoryChunk.num

Readable from: anywhere
Writable from: nowhere

field KoboldStoryChunk.num: integer

The number of the story chunk. Chunk 0 is guaranteed to be the prompt chunk if it exists; no guarantees can be made about the numbers of other chunks.

kobold.submission

Readable from: anywhere
Writable from: input modifier

field kobold.submission: string

The user-submitted text after being formatted by input formatting. If this is a repeated generation incurred by kobold.restart_generation(), then this is the empty string.

kobold.worldinfo

field KoboldLib.worldinfo: KoboldWorldInfo

Represents the world info entries.

Indexing this object at index i returns the ith world info entry from the top in amortized constant worst-case time as a KoboldWorldInfoEntry. This includes world info entries that are inside folders.

local entry = kobold.worldinfo[5]  -- Retrieves fifth entry from top as a KoboldWorldInfoEntry

You can use ipairs or a numeric loop to iterate from top to bottom:

for index, entry in ipairs(kobold.worldinfo):
    print(index, entry.content)
end

for index = 1, #kobold.worldinfo do:
    print(index, kobold.worldinfo[index].content)
end

Methods:

Fields:

kobold.worldinfo:compute_context()

function KoboldWorldInfo:compute_context(submission: string, entries?: KoboldWorldInfoEntry|table<any, KoboldWorldInfoEntry>, kwargs?: table<string, any>) -> string

Computes the context that would be sent to the generator with the user’s current settings if submission were the user’s input after being formatted by input formatting. The context would include memory at the top, followed by active world info entries, followed by some story chunks with the author’s note somewhere, followed by submission.

Parameters

Returns

string: Computed context.

kobold.worldinfo:finduid()

Callable from: anywhere

function KoboldWorldInfo:finduid(u: integer) -> KoboldWorldInfoEntry?

Returns the world info entry with the given UID in amortized constant worst-case time, or nil if not found.

This always returns true.

kobold.worldinfo.folders

Readable from: anywhere
Writable from: nowhere

field KoboldWorldInfo.folders: KoboldWorldInfoFolderSelector

Can be indexed in amortized constant worst-case time and iterated over and has a finduid method just like kobold.worldinfo, but gets folders (as KoboldWorldInfoFolder objects) instead.

local folder = kobold.worldinfo.folders[5]  -- Retrieves fifth folder from top as a KoboldWorldInfoFolder

for index, folder in ipairs(kobold.worldinfo.folders):
    print(index, folder.name)
end

for index = 1, #kobold.worldinfo.folders do:
    print(index, kobold.worldinfo.folders[index].name)
end

Fields:

KoboldWorldInfoEntry:compute_context()

Callable from: anywhere

function KoboldWorldInfoEntry:compute_context(submission: string, kwargs?: table<string, any>) -> string

The same as calling kobold.worldinfo:compute_context() with this world info entry as the argument.

Parameters

Returns

string: Computed context.

KoboldWorldInfoEntry:is_valid()

Callable from: anywhere

function KoboldWorldInfoEntry:is_valid() -> boolean

Writable from: anywhere

field KoboldWorldInfoEntry.comment: string

The world info entry’s comment that appears in its topmost text box.

KoboldWorldInfoEntry.constant

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

field KoboldWorldInfoEntry.constant: boolean

Whether or not this world info entry is constant. Constant world info entries are always included in the context regardless of whether or not its keys match the story chunks in the context.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

KoboldWorldInfoEntry.content

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

field KoboldWorldInfoEntry.content: string

The text in the “What To Remember” text box that gets included in the context when the world info entry is active.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

KoboldWorldInfoEntry.folder

Readable from: anywhere
Writable from: nowhere

field KoboldWorldInfoEntryfolder: integer?

UID of the folder the world info entry is in, or nil if it’s outside of a folder.

KoboldWorldInfoEntry.key

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

field KoboldWorldInfoEntry.key: string

For non-selective world info entries, this is the world info entry’s comma-separated list of keys. For selective world info entries, this is the comma-separated list of primary keys.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

KoboldWorldInfoEntry.keysecondary

Readable from: anywhere
Writable from: anywhere (triggers regeneration when written to from generation modifier)

field KoboldWorldInfoEntry.keysecondary: string

For non-selective world info entries, the value of this field is undefined and writing to it has no effect. For selective world info entries, this is the comma-separated list of secondary keys.

Modifying this field from inside of a generation modifier triggers a regeneration, which means that the context is recomputed after modification and generation begins again with the new context and previously generated tokens. This incurs a small performance penalty and should not be performed in excess.

KoboldWorldInfoEntry.num

Readable from: anywhere
Writable from: nowhere

field KoboldWorldInfoEntry.num: integer

This is 0 if the entry is the first one from the top, 1 if second from the top, and so on.

KoboldWorldInfoEntry.selective
