Code Intelligence Token Reduction Benchmark

Benchmark Date: December 22, 2025 Version: Agentic QE Fleet v2.6.0

Overview

The Code Intelligence System provides semantic code understanding that dramatically reduces token consumption when QE agents analyze codebases. Instead of loading entire files, agents receive only the most relevant code chunks based on semantic similarity.

Benchmark Methodology

Test Query: "How does the authentication flow work?"

Baseline Approach (without Code Intelligence):

• Load all potentially relevant files (6 files)
• Include complete file contents in context
• Agent must scan through irrelevant code

Code Intelligence Approach:

• Semantic search finds most relevant code chunks
• Knowledge graph provides relationship context
• Only 2 highly-relevant chunks included

Results

Token Consumption Comparison

Metric	Baseline	Code Intelligence	Improvement
Input Tokens	1,671	336	-79.9%
Output Tokens	472	472	-
Total Tokens	2,143	808	-62.3%
Context Files	6	2	-4 files
Context Lines	270	55	-215 lines
Relevance Score	35%	92%	+57%

Key Findings

• 79.9% reduction in input tokens per query
• 62.3% reduction in total token consumption
• 2.6x improvement in context relevance (92% vs 35%)
• Faster agent response due to focused context

Cost Impact

Based on Claude API pricing ($0.003/1K input tokens, $0.015/1K output tokens):

Usage Level	Baseline Cost	With Code Intelligence	Monthly Savings
10 queries/day	$1.95/mo	$0.39/mo	$1.56
100 queries/day	$19.47/mo	$3.87/mo	$15.60
1,000 queries/day	$194.70/mo	$38.70/mo	$156.00

How It Works

1. Semantic Indexing

Source Code → Tree-sitter Parser → AST Chunks → Ollama Embeddings → Vector DB

2. Query Processing

User Query → Embedding → Hybrid Search (Vector + BM25) → Top-K Chunks

3. Context Enrichment

Relevant Chunks → Knowledge Graph → Related Symbols → Focused Context

Getting Started

Prerequisites

# Start Ollama with embedding model
ollama pull nomic-embed-text
ollama serve

# Start RuVector (PostgreSQL with pgvector)
docker-compose up -d ruvector

Enable Code Intelligence

# During init
aqe init  # Select "Enable Code Intelligence"

# Or enable later
aqe code-intel enable
aqe code-intel index src/

Query Your Codebase

aqe code-intel search "authentication flow"
aqe code-intel graph --symbol AuthService

Conclusion

The Code Intelligence System delivers significant value:

• 80% token reduction = Lower API costs
• 92% context relevance = More accurate agent responses
• Semantic understanding = Agents find what matters
• Knowledge graph = Relationship-aware context

For teams running 100+ queries/day, this translates to $15-150/month in savings while improving response quality.
