Detailed analysis
Pricing
Winner: GPT-5 CodexGPT-5 Codex is priced at $10 per 1M output tokens while GPT Chat Latest costs $30 per 1M. Both share identical 400k context windows, so Codex delivers the same scale at one-third the cost.
Speed
Winner: GPT-5 CodexGPT-5 Codex reports a concrete 149.9 t/s output speed. GPT Chat Latest provides no speed figure, leaving Codex as the only model with a measurable throughput advantage.
Input Handling
Winner: GPT Chat LatestGPT Chat Latest explicitly supports text, image, and file inputs plus extended documents. GPT-5 Codex is limited to text and static images with noted coherence risks on very long outputs.
Specialization
Winner: GPT-5 CodexGPT-5 Codex lists strong coding specialization and unified text-image reasoning with a 44.6 intelligence index. GPT Chat Latest emphasizes general flexibility and multi-turn dialogue without a reported intelligence score.
