"Register an Ollama backend for gptel with NAME.
Keyword arguments:
CURL-ARGS (optional) is a list of additional Curl arguments.
HOST is where Ollama runs (with port), defaults to localhost:11434
MODELS is a list of available model names, as symbols.
Additionally, you can specify supported LLM capabilities like
vision or tool-use by appending a plist to the model with more
information, in the form
(model-name . plist)
Currently recognized plist keys are :description, :capabilities
and :mime-types. An example of a model specification including
both kinds of specs:
:models
\\='(mistral:latest ;Simple specs
openhermes:latest
(llava:13b ;Full spec
:description
\"Llava 1.6: Large Lanuage and Vision Assistant\"
:capabilities (media)
:mime-types (\"image/jpeg\" \"image/png\")))
STREAM is a boolean to toggle streaming responses, defaults to
false.
PROTOCOL (optional) specifies the protocol, http by default.
ENDPOINT (optional) is the API endpoint for completions, defaults to
\"/api/generate\".
HEADER (optional) is for additional headers to send with each
request. It should be an alist or a function that retuns an
alist, like:
((\"Content-Type\" . \"application/json\"))
KEY (optional) is a variable whose value is the API key, or
function that returns the key. This is typically not required
for local models like Ollama.
REQUEST-PARAMS (optional) is a plist of additional HTTP request
parameters (as plist keys) and values supported by the API. Use
these to set parameters that gptel does not provide user options
for.
Example:
-------
(gptel-make-ollama
\"Ollama\"
:host \"localhost:11434\"
:models \\='(mistral:latest)
:stream t)"
(declare (indent 1))
(let ((backend (gptel--make-ollama
