# The Five Levels of AI Coding Autonomy

The five levels of AI coding autonomy is [Dan Shapiro](../entities/people/dan-shapiro.md)'s framework for grading how much control you have handed to a coding agent: "five levels from spicy autocomplete to the dark factory. And it's really important for you to understand the level that you're currently at and what you should be shooting for" [0:00:18]. The scale is borrowed wholesale from driving - "this entire article uses the analogy of driving a vehicle because there's a company in 2013 that created the five levels of driving automation" [0:01:05] - which is what makes it useful: the question is never how smart the model is, it is who is in the driver's seat.

The rungs:

- **Level 0, spicy autocomplete.** A smarter Stack Overflow. You write every line.
- **Level 1, coding intern.** Cruise control for boilerplate, repo setup, unit tests, simple refactors.
- **Level 2, junior developer.** Pair programming with something you trust situationally, never fully. Most people are here.
- **Level 3, the developer.** You delegate *all* coding, sandwiched between planning and validation you personally take part in.
- **Level 4, engineering team.** You hand off whole epics, PRDs, or specs and validate at the end through pull requests.
- **Level 5, the [dark factory](./dark-factory.md).** Spec in, shipped production code out, nobody in the driver's seat.

Cole's thesis is that the top of the ladder is not the goal. Level three is the sweet spot of reliability and autonomy - he has not written a line of code himself in over a year while staying in the loop for plan and validate, exactly the shape of [The PIV Loop](./the-piv-loop.md). Reliability tanks at four and five until you have a battle-tested workflow, so the advice is to reach level three and *stay there a while*, evolving the system, before climbing further. Each level up is not a better model, it is a bigger unit of delegation, and every unit of delegation has to be backed by [validation](./validation.md) you actually trust.

That reframes the ladder as a maturity model for your system rather than a ranking of tools. Climbing means investing in [the AI layer](./the-ai-layer.md) (rules, subagents, skills on top of an [AI coding harness](./ai-coding-harness.md)) and practicing [system evolution](./system-evolution.md) after every mistake, so the level you can hold is set by the reliability you have engineered, not by ambition.

## Builds on

- [The Evolution of AI Coding](./the-evolution-of-ai-coding.md) - the arc from autocomplete to autonomous agents this scale grades.

## Contrasts with

- [Vibe Coding](./vibe-coding.md) - autonomy without the planning and validation sandwich, which is not a level, it is a skipped step.

## Related

- [Dark Factory](./dark-factory.md) - level five, the frontier Cole runs as an experiment rather than a recommendation.
- [The PIV Loop](./the-piv-loop.md) and [Validation](./validation.md) - what makes level three trustworthy.
- [Human in the Loop](./human-in-the-loop.md) - the variable the whole scale actually measures.
- [The AI Layer](./the-ai-layer.md), [AI Coding Harness](./ai-coding-harness.md), [System Evolution](./system-evolution.md) - what you build to earn a higher level.
- [Spec-Driven Development](./spec-driven-development.md) - the spec is the unit of delegation at levels four and five.
- [The Evolving Role of the Software Engineer](./evolving-role-of-the-engineer.md) - what your job becomes as the level rises.
- [Long-Running Agents](./long-running-agents.md), [Parallel Agentic Coding](./parallel-agentic-coding.md) - the execution shapes of level four.
- [Agentic Coding](./agentic-coding.md) - the practice being graded.
- [Permission Management](./permission-management.md) - Allowlisting the specific safe commands an agent may run unattended, and using an isolated firewalled container when you do skip permissions entirely.
- [Puppeteer](../entities/tools/puppeteer.md) - Browser-automation MCP server that lets a coding agent load pages, click, and screenshot to visually validate that a feature actually works before marking it passed.
- [Tabnine](../entities/tools/tabnine.md) - An AI code-completion assistant that fills in large blocks of code, inferring things like a full database schema from just the name you type.
