How I Consumed 20 Billion Tokens in 2025: A Retrospective

15 min read

TL;DR(Too Long; Didn't Read)

AI is not just autocomplete; it is a reasoning engine. Consuming 20B tokens taught me that "prompt engineering" is actually systems design. Key takeaways: Context is king, agents need boundaries, and the human role has shifted from writer to editor-in-chief. This workflow enables 10x velocity.

In 2025, I didn't just write code. I orchestrated it. By the end of the year, my personal telemetry showed a staggering number: 20 Billion Tokens consumed across GPT-4, Claude 3.5 Sonnet, and local models.

The Shift: From Writer to Editor

The traditional view of a "Senior Engineer" is someone who writes clean, efficient code by hand.That definition is dead.

When you have immediate access toAI - Native Architecture, your role shifts.You are no longer the bricklayer; you are the architect and the foreman.I found that I spent 80 % of my time reviewing and designing , and only 20 % actually typing syntax.

The "Context Window" is Your New RAM

The biggest bottleneck in 2025 wasn't model intelligence; it was context. Managing what the AI "knows" about your project is the new skill ceiling.

Key Learnings: 1. Cursor Rules: `.cursorrules` files are not optional. They are your new documentation. 2. Vector Embeddings: Creating a RAG pipeline for your own codebase is essential for anything over 10k lines of code.

Velocity impacts Quality (Positively)

Counter-intuitively, moving faster increased quality. Why? Because the cost of writing tests dropped to near zero.

With AI-powered tools, I could generate comprehensive integration test suites for every feature flag. This creates a safety net that allows for aggressive refactoring—a core tenet of our Zero Debt philosophy.

The 100x Architect

The industry talks about the "10x Developer". I believe the "100x Architect" is the reality of 2026. A single architect, armed with the right agents, can output the work of a 10-person dev team.

This isn't theory. At Slickrock, we run lean by design. If you want to see this velocity applied to your project, check out our Technical Blueprints.
