How to Reduce AI Token Costs by 90% in Production

Learn how smart context management can reduce your AI development costs by 90% without sacrificing code quality or accuracy.

AI-powered development platforms face a critical challenge: token costs can spiral out of control. Loading entire codebases into context for every request is expensive and inefficient. Here's how we solved it.

The Token Cost Problem

Traditional AI coding assistants load 50+ files (25K tokens) per request. At scale, this becomes unsustainable. A single complex deployment can consume your entire monthly token budget.

Smart Context Management

Instead of loading everything, use heuristic filtering to load only relevant files. Our approach: exact filename matching (100 points), directory matching (50 points), entry points (30 points), and cross-file dependencies.

Session Memory

Remember files the agent recently worked with. This creates continuity across conversation turns without re-loading context. Uses DynamoDB with 30-minute TTL for automatic decay.

Results

90% token reduction (25K → 2.5K tokens per request). 5 files loaded instead of 50. ~80% accuracy maintained. Predictable costs at scale.
