What this workflow does
This AI workflow has 31 nodes and runs when a chat message arrives. Along the way it connects Google Gemini Chat Model and Redis. It also calls generativelanguage.googleapis.com over HTTP.
How it runs
Trigger: When a chat message arrives.
- Configs (Edit Fields (Set)): sets 4 fields: number_of_initial_queries, max_research_loops, current_date…
- generate_query (Basic LLM Chain): sends a prompt to an LLM, with model: Google Gemini Chat Model; output parser: Structured Output Parser
- set search_query (Edit Fields (Set)): sets or maps fields
- Split Out: splits a list into separate items
- search_query (Edit Fields (Set)): sets or maps fields
- number_of_ran_queries (Redis): incr
- attach index as id (Code): runs custom JavaScript code
- GeminiSearch (HTTP Request): calls generativelanguage.googleapis.com (POST)
- web_search (Code): runs custom JavaScript code
- merge web_search_result (Aggregate): combines items into one
…plus 17 more steps. See the full node list below.
Services it uses
HTTP calls to: generativelanguage.googleapis.com
