Worked on stabilizing the LLM integration for the neo4j-labs/llm-graph-builder repository by addressing a critical environment configuration issue. Focused on restoring reliable access to the Llama-4-Maverick model, the work involved correcting the API endpoint and API key, which eliminated integration errors and improved the consistency of model calls. Utilized skills in AI model management, API integration, and environment configuration, with changes tracked through environment variable updates. This fix enhanced the reliability of downstream graph-building workflows and reduced production risk by ensuring that deployment environments maintained consistent and validated access to LLM capabilities across different stages of the pipeline.
