Use when latency/cost matters more than deep reasoning. GPT-5.2 Thinking (gpt-5.2): Strategy, analysis, research synthesis, complex edge cases. Type: Text (reasoning). ChatGPT label. In the API you typically use gpt-5.2 and control reasoning via settings. GPT-5.2 Pro (gpt-5.2-pro): High-stakes decisions, pricing logic, policy-heavy support flows. Type: Text (deep reasoning). Slower, but typically fewer logic errors. Good when mistakes are expensive. GPT-5.3 Codex (gpt-5.3-codex): Shopify theme/app dev, integrations, refactors, debugging. Type: Coding agent. Best used via the Codex product (CLI/IDE/Cloud). API access coming soon — phased rollout underway. GPT-5.3 Codex-Spark (gpt-5.3-codex-spark): Rapid prototyping, small edits, boilerplate, front-end iteration. Type: Coding (ultra-fast). Research preview for ChatGPT Pro users.
