Google Jules vs OpenAI Codex, side by side
Field	Google Jules	OpenAI Codex
Tier	B Shutting down 31 Dec 2026 Google is winding Jules down: sessions are allowed until 11 Nov 2026, then it is read-only, and it shuts down on 31 Dec 2026. Source	S
Why this tier	It is a free async agent for small tasks. For most builders it is not a daily driver, so it sits at B-tier. Google is winding Jules down and it shuts down on 31 Dec 2026, so the B-tier only holds while it still runs.	It sits on par with Claude Code at the top of the coding-agent list. It runs as an open-source CLI, an IDE extension and cloud tasks. If you already pay for ChatGPT, it is the natural first pick.
Best for	Small async tasks for free, while it still runs (sessions until 11 Nov 2026) Trying a cloud agent without paying	People who already pay for ChatGPT Running coding tasks in the CLI, the IDE or the cloud
Skip if	You need a tool you can rely on past 31 Dec 2026 You need a daily-driver agent You want hands-on, step-by-step control	You don't use ChatGPT and want the deepest terminal agent (see Claude Code) You want a no-code app builder
