Resolution criteria
This market resolves YES if GPT-5.4-Codex (or any higher Codex version number) is released before GPT-5.3 (or any higher GPT version number). The market resolves NO if GPT-5.3 is released first, or if both are released simultaneously. Resolution will be determined by official OpenAI announcements and release dates published on OpenAI's official website or OpenAI's blog.
Background
GPT-5 was unveiled by OpenAI on August 7, with GPT-5.2 released as the next upgrade to the GPT-5 series. GPT-5.3-Codex is the most capable agentic coding model to date, advancing both the frontier coding performance of GPT-5.2-Codex and the reasoning and professional knowledge capabilities of GPT-5.2. GPT-5.3-Codex is now rolling out in GitHub Copilot. Codex is OpenAI's specialized coding agent, while GPT versions are general-purpose models.
Considerations
The question assumes both GPT-5.4-Codex and GPT-5.3 will eventually be released. If either model is never released, the market will resolve N/A. Additionally, version numbering for Codex and GPT may diverge in the future—the market resolves based on whichever next version is released first, regardless of the specific version number.
