STACKED FROM ONE: MULTI-SCALE SELF-INJECTION FOR CONTEXT WINDOW EXTENSION
This paper introduces SHAREDLLM, a novel framework designed to address the critical bottleneck of limited context windows in Large Language Models (LLMs). By employing a multi-grained context compression and query-aware information acquisition via a self-injection mechanism and a specialized tree-based data structure, SHAREDLLM effectively extends LLM context capabilities to over 128K tokens from an 8K token training base, demonstrating superior performance and significant efficiency gains.
Executive Impact
SHAREDLLM represents a significant leap in LLM capabilities, directly addressing scalability and efficiency for enterprise applications that demand extensive contextual understanding.
Key Challenges Addressed
Limited Context Windows: Existing LLMs struggle with inputs exceeding their typically small context limits, leading to performance degradation and hallucination.
Prohibitive Training Costs: Extending context windows through continual pre-training is computationally expensive and data-intensive.
Efficiency Bottlenecks: Quadratic complexity of standard self-attention (O(T²)) leads to high memory consumption and slow inference for long sequences.
Proposed Solution: SHAREDLLM
SHAREDLLM introduces a novel hierarchical architecture with two stacked short-context LLMs: a lower model (compressor) and an upper model (decoder). The lower model compresses long inputs into compact, multi-grained representations, which are then passed to the upper model for context-aware processing. This self-injection mechanism, derived from the same underlying LLM layers, uses a specialized tree-based data structure (context tree) for efficient encoding and query-aware retrieval of contextual information, transferring data exclusively at the lowest layers to maximize efficiency.
Core Innovations
Multi-Scale Self-Injection: A hierarchical architecture where lower model compresses and upper model decodes, with shared KV states and minimal tunable parameters.
Query-Dependent Context Tree: A dynamic, tree-like structure for coarse-to-fine representation and efficient retrieval of task-relevant information from long unstructured contexts.
Exceptional Extrapolation: Achieves robust performance on inputs exceeding 128K tokens, despite training on only 8K token sequences.
Significant Efficiency Gains: Substantially reduces memory footprint and yields notable inference speedups (2x over streaming, 3x over encoder-decoder architectures).
Business Implications
Enterprises can leverage SHAREDLLM for advanced applications requiring deep understanding of large documents, such as legal contract analysis, extensive literature review, long-form customer service interactions, and complex codebases. The model's efficiency reduces operational costs, while its extended context window unlocks new possibilities for automated intelligence, improving decision-making and enhancing productivity across various domains.

| Feature/Metric | SHAREDLLM Advantage | Traditional LLMs/Baselines |
|---|---|---|
| Context Window | 128K+ tokens (from 8K training) | Limited (e.g., 8K, often OOM at 128K) |
| Efficiency | 2-3x faster inference, substantially reduced memory | Quadratic complexity (O(L^2)), high memory, slower |
| Architecture | Hierarchical, multi-grained, self-injection, tree-based retrieval | Monolithic, dense attention, often requires full pre-training |
| Training Cost | Minimal fine-tuning from off-the-shelf LLMs | Prohibitive data acquisition & computational costs for long context |
| Generalization | Strong extrapolation without performance degradation | Performance degradation, hallucination beyond trained context |
Enterprise-Grade Document Analysis
Imagine an enterprise needing to process vast archives of legal documents, research papers, or customer interactions for compliance, market intelligence, or customer service. Traditional LLMs struggle with the sheer volume of text, leading to costly repeated calls, out-of-memory errors, and limited insights. SHAREDLLM's ability to handle 128K+ tokens with 2-3x faster inference and reduced memory makes it ideal. It can efficiently digest entire legal contracts or years of customer feedback, extracting fine-grained details when needed, while maintaining a broad overview for summarization. This allows for unprecedented scale in automated document processing, accelerating decision-making and significantly reducing operational overhead.
