Summary

The "Tokenminning" pattern offers a systematic approach to minimize token usage in AI agents, directly countering "Tokenmaxxing" practices that inflate costs, latency, and degrade output quality due to "context rot." Naïve token usage, exemplified by daily agent consumption of over 1.2 million tokens, can lead to significant expenses, with some engineers reporting over \$10,000 per week. This article details two key strategies for token efficiency. First, prompt routing involves an LLM Gateway that preprocesses, evaluates, and routes requests based on intent and complexity to the most cost-effective model, such as Qwen 3.5 9B for simple tasks or o3-pro for complex code generation. This method alone reduced AI usage costs by over 60%. Second, lossy context compaction summarizes long-running agent conversation history using a lower-order model when approaching a predefined token threshold, like 32,000 tokens, to preserve critical information while discarding redundancy.

Key takeaway

For MLOps Engineers managing escalating LLM API costs and performance for AI agents, you should prioritize implementing tokenminning strategies. Deploy an LLM Gateway to intelligently route prompts to the most cost-effective model based on task intent and complexity, potentially reducing your usage costs by over 60%. Additionally, integrate lossy context compaction into long-running agents to summarize conversation history at predefined thresholds, ensuring critical information is retained while minimizing token bloat and "context rot."

Key insights

Tokenminning systematically minimizes AI token use to reduce costs, latency, and improve output quality.

Principles

• Excessive tokens often degrade LLM performance and increase costs.
• Context quality, not volume, drives effective AI use.
• Match model capability to prompt complexity for efficiency.

Method

Deploy an LLM Gateway to intercept prompts, classify intent and complexity, then route to the most suitable, cost-effective LLM via predefined rules.

In practice

• Develop a prompt classifier using a DeBERTa backbone for routing.
• Implement lossy context compaction for long-running agents at thresholds.
• Prioritize premium models for code generation to reduce errors.
