Sep 1, 2025Month: 2025-09 — OpenDCAI/DataFlow: Chemistry pipelines: structured JSON output and API serving reliability improvements. Implemented structured JSON output by introducing a response_format argument to the LLM serving layer; enhanced error handling for JSON parsing of generated outputs. Also removed unused parameters (response_format and temperature) from LLM serving classes to simplify API calls, fix potential errors, and improve reliability. These changes were implemented across two commits: 8b55755892d6a3342b3c347fb27cace7dc17445a and 7dbe5d47e123a5546ce4bcbd4fc5ce0d02d1d70c. These changes improve downstream integration, reliability, and overall API stability.
