Models, harnesses and the next year

Separate observed performance from product choices and forecasts. This draft does not establish a universal model ranking.

Working notes

  • The sessions show complementary Claude and Codex roles, with each catching mistakes the other missed.
  • Matched briefs and sandbox access changed apparent comparison outcomes.
  • The corpus does not directly evaluate open models or open-source harnesses.
  • Provider-hosted and self-managed cloud workflows also lack direct evidence here.

Source: course evidence synthesis, §7–8. These are selected observations, not general performance guarantees.

Subscriptions and 2027

  • [TODO: verify subscriptions, employer support and six-hour usage limits before the course.]
  • [TODO: substantiate the opinion that competition is improving open models; “capitalism is doing its job” is a framing, not a benchmark.]
  • [TODO: distinguish demonstrated 2026 capabilities, 2027 forecasts and work that still needs domain expertise.]

Before the course

  • [TODO: select a compact worked example and its verification artifact.]
  • [TODO: rehearse the live walkthrough and prepare a fallback.]
