Natural Language Filtering for Traces

You can now construct filters for traces and observations using natural language. Instead of manually building complex filters, simply describe what you’re looking for in plain English and Langfuse will automatically construct the appropriate filters. You can then refine the generated filters manually if needed.

Examples

• “Find all default level traces with latency greater than 2 seconds”
• “Show me traces with errors from production”
• “Filter for traces with over 9000 tokens”

How to Enable
