Model aliases

LLM supports model aliases, which allow you to refer to a model by a short name instead of its full ID.

Listing aliases

To list current aliases, run this:

llm aliases

Example output:

3.5              : gpt-3.5-turbo
chatgpt          : gpt-3.5-turbo
chatgpt-16k      : gpt-3.5-turbo-16k
3.5-16k          : gpt-3.5-turbo-16k
4                : gpt-4
gpt4             : gpt-4
4-32k            : gpt-4-32k
gpt-4-turbo      : gpt-4-turbo-preview
4-turbo          : gpt-4-turbo-preview
4t               : gpt-4-turbo-preview
3.5-instruct     : gpt-3.5-turbo-instruct
chatgpt-instruct : gpt-3.5-turbo-instruct
ada              : ada-002 (embedding)

Add --json to get that list back as JSON:

llm aliases list --json

Example output:

{
    "3.5": "gpt-3.5-turbo",
    "chatgpt": "gpt-3.5-turbo",
    "chatgpt-16k": "gpt-3.5-turbo-16k",
    "3.5-16k": "gpt-3.5-turbo-16k",
    "4": "gpt-4",
    "gpt4": "gpt-4",
    "4-32k": "gpt-4-32k",
    "ada": "ada-002"
}

Adding a new alias

The llm aliases set <alias> <model-id> command can be used to add a new alias:

llm aliases set turbo gpt-3.5-turbo-16k

Now you can run the gpt-3.5-turbo-16k model using the turbo alias like this:

llm -m turbo 'An epic Greek-style saga about a cheesecake that builds a SQL database from scratch'

Aliases can be set for both regular models and embedding models using the same command. To set an alias of oai for the OpenAI ada-002 embedding model use this:

llm aliases set oai ada-002

Now you can embed a string using that model like so:

llm embed -c 'hello world' -m oai

Output:

[-0.014945968054234982, 0.0014304015785455704, ...]

Removing an alias

The llm aliases remove <alias> command will remove the specified alias:

llm aliases remove turbo

Viewing the aliases file

Aliases are stored in an aliases.json file in the LLM configuration directory.

To see the path to that file, run this:

llm aliases path

To view the content of that file, run this:

cat "$(llm aliases path)"
