Create environments llm analytics summarization

Generate an AI-powered summary of an LLM trace or event.

This endpoint analyzes the provided trace/event, generates a line-numbered text representation, and uses an LLM to create a concise summary with line references.

Summary Format:

  • 5-10 bullet points covering main flow and key decisions
  • "Interesting Notes" section for failures, successes, or unusual patterns
  • Line references in [L45] or [L45-52] format pointing to relevant sections

Feature Flag:

  • Requires llm-analytics-summarization feature flag enabled at team level

Use Cases:

  • Quick understanding of complex traces
  • Identifying key events and patterns
  • Debugging with AI-assisted analysis
  • Documentation and reporting

The response includes the summary text and optional metadata.

Create environments llm analytics text repr

Generate a human-readable text representation of an LLM trace event.

This endpoint converts LLM analytics events ($ai_generation, $ai_span, $ai_embedding, or $ai_trace) into formatted text representations suitable for display, logging, or analysis.

Supported Event Types:

  • $ai_generation: Individual LLM API calls with input/output messages
  • $ai_span: Logical spans with state transitions
  • $ai_embedding: Embedding generation events (text input → vector)
  • $ai_trace: Full traces with hierarchical structure

Options:

  • max_length: Maximum character count (default: 4000000)
  • truncated: Enable middle-content truncation within events (default: true)
  • truncate_buffer: Characters at start/end when truncating (default: 1000)
  • include_markers: Use interactive markers vs plain text indicators (default: true)
    • Frontend: set true for <<<TRUNCATED|base64|...>>> markers
    • Backend/LLM: set false for ... (X chars truncated) ... text
  • collapsed: Show summary vs full trace tree (default: false)
  • include_hierarchy: Include tree structure for traces (default: true)
  • max_depth: Maximum depth for hierarchical rendering (default: unlimited)
  • tools_collapse_threshold: Number of tools before auto-collapsing list (default: 5)
    • Tool lists >5 items show <<<TOOLS_EXPANDABLE|...>>> marker for frontend
    • Or [+] AVAILABLE TOOLS: N for backend when include_markers: false
  • include_line_numbers: Prefix each line with line number like L001:, L010: (default: false)

Use Cases:

  • Frontend display: truncated: true, include_markers: true, include_line_numbers: true
  • Backend LLM context (summary): truncated: true, include_markers: false, collapsed: true
  • Backend LLM context (full): truncated: false

The response includes the formatted text and metadata about the rendering.
