Legal Discovery Document Analysis

Legal firms managing massive litigation discovery datasets.

The business problem

Manual review of multi-million token document sets leads to missed evidence and prohibitive labor costs.

How this topic solves it

Utilizing Qwen3-235B-A22B-Instruct-2507 with its 1M token context window and Dual Chunk Attention to ingest entire case files for automated retrieval and summarization.

  1. Configure the model environment with the 1M token config_1m.json file.
  2. Deploy the model using vLLM with VLLM_ATTENTION_BACKEND=DUAL_CHUNK_FLASH_ATTN to handle long-context memory requirements.
  3. Integrate the Qwen-Agent framework to define custom retrieval tools for specific legal document types.
  4. Execute batch processing of discovery documents using chunked prefill to maintain system stability.
Legal Discovery Pipeline · Process flow

The flow of documents from storage through the long-context model to the legal analyst.

Implementation example

This code demonstrates initializing the Qwen-Agent to utilize the model's tool-calling capabilities for processing large document sets.

python · Illustrative code; not executed or production-validated.

from qwen_agent.agents import Assistant
# Define LLM with custom endpoint
llm_cfg = {'model': 'Qwen3-235B-A22B-Instruct-2507', 'model_server': 'http://localhost:8000/v1'}
# Define tools for document retrieval
tools = ['code_interpreter']
bot = Assistant(llm=llm_cfg, function_list=tools)
# Run analysis on long-context input
messages = [{'role': 'user', 'content': 'Analyze these 500k tokens of discovery...'}]
for responses in bot.run(messages=messages): pass

Expected business outcome

Legal teams achieve rapid identification of relevant case facts across vast document archives without manual triage.

Limitations and checks

The 1M token context requires approximately 1000 GB of GPU memory; check for OOM errors by monitoring KV cache utilization or reducing max_num_batched_tokens.
