String

detail_level

Summary detail level: Low (very concise), Medium (balanced), High (comprehensive).

Default Medium

Include TOC

Boolean

include_toc

Whether to include a table of contents with page references.

Default true

Strategy

String

strategy

Summarization strategy: • Refine — sequential, best coherence, no parallelism • MapReduce — parallel chunking, fast, may lose cross-chunk context • Hierarchical — structure-aware tree, best for headed documents • Hybrid — MapReduce speed + Refine coherence polish • SlidingWindow — fixed memory buffer, best for very long documents

Default Refine

RefineMapReduceHierarchicalHybridSlidingWindow

Densification

String

densification

Post-processing to increase information density: • None — use the strategy output as-is • ChainOfDensity — iteratively compress to optimal density

Default None

NoneChainOfDensity

Max Context Tokens

Integer

max_context_tokens

Maximum characters per summarization chunk (adjust based on model context window).

Default 8000

Chunk Overlap %

Integer

chunk_overlap

Overlap between adjacent chunks as percentage (0-50). Prevents information loss at boundaries (default: 10).

Default 10

Track Entities

Boolean

track_entities

Extract and track named entities across chunks to prevent information loss.

Default false

Parallel Requests

Integer

parallel_requests

Number of chunks to process in parallel for MapReduce/Hybrid strategies. 0 = unlimited (default: 4).

Default 4

Density Steps

Integer

density_steps

Number of Chain of Density refinement steps when densification is enabled (1-5, default: 3).

Default 3
