This node establishes a connection with an OpenAI LLM.
After successfully authenticating using the OpenAI Authenticator node , you can select an LLM from a predefined list or explore advanced options to get a list of all models available for your API key (including fine-tunes).
Note that only models compatible with OpenAI's Completions API will work with this node (unfortunately this information is not available programmatically). Find documentation about all models at OpenAI .
If you are looking for gpt-3.5-turbo or gpt-4, check out the OpenAI Chat Model Connector node.
Note : If you use the Credentials Configuration node and do not select the "Save password in configuration (weakly encrypted)" option for passing the API key, the Credentials Configuration node will need to be reconfigured upon reopening the workflow, as the credentials flow variable was not saved and will therefore not be available to downstream nodes.
