Agents Are More Token Efficient with Flyte v2

AbstractCoding agents now author most Flyte pipelines; the DSL a human rarely reads is a DSL an agent must get exactly right on every turn. We benchmark that authoring cost directly: the same Claude Code subagent, same model, same turn budget, primed with an equal-token-budget cheatsheet for Flyte v1 (flytekit) or Flyte v2 (flyte), writes a pipeline for each of 12 framework-agnostic specs against a real cluster, graded by a live oracle — 48 trials total, no simulation. On the nine specs both frameworks can express, v2 reaches a passing run in 1.78× fewer tokens and a 5× lower iteration count, with essentially every v1 failed iteration (54 of 54 logged, vs. v2's 1) being framework-mechanics friction rather than a logic bug. On three specs that require catching a live task failure as control flow, racing concurrent tasks with cancellation, or checkpointing an in-process loop, v1 recorded 0% success (6/6 infeasible) while v2 solved 6/6 — not an efficiency gap but a capability one.
