GitHub explains new AI vocabulary for developers.
Terms include loops, squads, harnesses, and hill climbing.
These concepts aim to structure AI workflows and improve agent performance.
What happened
GitHub's podcast episode and a guide explain new AI-related terms in software development, including loop engineering, Ralph loops, squads, fleets, harnesses, hill climbing, and model openness levels.
Why it matters
These terms describe emerging patterns for using AI agents, such as repeatable workflows (loops) and multi-agent collaboration (squads/fleets), which can make development more efficient—though some, like Ralph loops, may be expensive due to high token and compute use.
What to watch
The article notes that some terms will stick, others will fade, and better language may emerge as the industry matures.

The surge of AI tools has introduced many new terms into software development, creating confusion for developers. GitHub's guide seeks to clarify these concepts, distinguishing between genuinely useful patterns and mere re-branding of existing ideas. For instance, forward deployed engineer is described as an existing role with an AI focus.
The article emphasizes that the underlying practices matter more than the buzzwords. Understanding loop engineering can help create repeatable workflows, while concepts like squads and fleets encourage parallelization and specialization. Model openness affects how much developers can customize and trust the software they build.
The guide suggests that the vocabulary is still evolving. Some terms will remain, while others may be replaced. For now, focusing on core principles—such as validation and reliability—will help developers adapt to this new era of engineering.
