This patch updates function "run" to "invoke" in smart_llm.ipynb.
Without this patch, you see following warning.
LangChainDeprecationWarning: The function `run` was deprecated in
LangChain 0.1.0 and will be removed in 0.2.0. Use invoke instead.

"# How to use a SmartLLMChain\n",
|
|
"\n",
|
|
"A SmartLLMChain is a form of self-critique chain that can help you if have particularly complex questions to answer. Instead of doing a single LLM pass, it instead performs these 3 steps:\n",
|
|
"1. Ideation: Pass the user prompt n times through the LLM to get n output proposals (called \"ideas\"), where n is a parameter you can set \n",
|
|
"2. Critique: The LLM critiques all ideas to find possible flaws and picks the best one \n",
|
|
"3. Resolve: The LLM tries to improve upon the best idea (as chosen in the critique step) and outputs it. This is then the final output.\n",
|
|
"\n",
|
|
"SmartLLMChains are based on the SmartGPT workflow proposed in https://youtu.be/wVzuvf9D9BU.\n",
|
|
"\n",
|
|
"Note that SmartLLMChains\n",
|
|
"- use more LLM passes (ie n+2 instead of just 1)\n",
|
|
"- only work then the underlying LLM has the capability for reflection, which smaller models often don't\n",
|
|
"- only work with underlying models that return exactly 1 output, not multiple\n",
|
|
