**Description:** Initial pull request for Kinetica LLM wrapper **Issue:** N/A **Dependencies:** No new dependencies for unit tests. Integration tests require gpudb, typeguard, and faker **Twitter handle:** @chad_juliano Note: There is another pull request for Kinetica vectorstore. Ultimately we would like to make a partner package but we are starting with a community contribution.

|
|
"\n",
|
|
"With the Kinetica LLM workflow you create an LLM context in the database that provides\n",
|
|
"information needed for infefencing that includes tables, annotations, rules, and\n",
|
|
"samples. Invoking ``ChatKinetica.load_messages_from_context()`` will retrieve the\n",
|
|
"context information from the database so that it can be used to create a chat prompt.\n",
|
|
"\n",
|
|
"The chat prompt consists of a ``SystemMessage`` and pairs of\n",
|
|
"``HumanMessage``/``AIMessage`` that contain the samples which are question/SQL\n",
|
|
"pairs. You can append pairs samples to this list but it is not intended to\n",
|
|
"facilitate a typical natural language conversation.\n",
|
|
"\n",
|
|
"When you create a chain from the chat prompt and execute it, the Kinetica LLM will\n",
|
|
"generate SQL from the input. Optionally you can use ``KineticaSqlOutputParser`` to\n",
|
|
"execute the SQL and return the result as a dataframe.\n",
|
|
"\n",
|
|
"Currently, 2 LLM's are supported for SQL generation: \n",
|
|
"\n",
|
|
"1. **Kinetica SQL-GPT**: This LLM is based on OpenAI ChatGPT API.\n",
|
|
"2. **Kinetica SqlAssist**: This LLM is purpose built to integrate with the Kinetica\n",
|
|
" database and it can run in a secure customer premise.\n",
