# CrewAI 1.15.38 makes gpt-6-luna the default model everywhere

Canonical: https://theagenticweekly.com/news/crewai-1-15-38 · Evidence: Reported · First seen: 2026-11-08 19:46 UTC · Source published: 2026-11-08 19:39 UTC · Brief published: 2026-11-08 20:05 UTC · Updated: 2026-11-08 20:05 UTC · Author: Agentic Weekly

> CrewAI 1.15.38, published November 8, 2026 on GitHub, lists as its first feature: "Make gpt-6-luna crewAI's default model everywhere."

## What changed

- The Features list opens with "Make gpt-6-luna crewAI's default model everywhere." Crews that do not set their own model would use gpt-6-luna after upgrading to 1.15.38, according to the notes.
- The notes also list "Read spreadsheet URLs in an agent's input with tools over every row." They do not say which hosts, file types or size limits apply.
- A Features item adds "--no-open to crewai eval for headless use," so an evaluation can skip opening a browser.
- Under Bug Fixes, the notes say the CLI will "Exit non-zero when crewai run's project script fails," which matters for CI jobs that treated a printed error as success.
- Another bug fix says the project .env is created "owner-only when crewai eval turns tracing on." The notes do not state the file mode.

## Early verdict

Anyone running CrewAI without pinning a model should read the 1.15.38 notes before upgrading, because they say gpt-6-luna is now the default everywhere. People who pass spreadsheet URLs into agent inputs, or who run crewai eval and crewai run in CI or over SSH, are the others most likely to notice; the notes do not describe this as an emergency upgrade. (Basis: Based only on the CrewAI 1.15.38 GitHub release notes as read on November 8, 2026; we have not run the release.)

## What we have not verified

- We did not install or run CrewAI 1.15.38, or try the gpt-6-luna default, spreadsheet URL reading, or the --no-open flag.
- We did not check gpt-6-luna's availability, pricing or behavior with OpenAI, or what CrewAI used as the default model before 1.15.38.
- We did not verify the .env permission change or the crewai run exit-code change on a real project.
