The author says Codex reached 20x, and the next hurdle is spec decoding for a hybrid parallel scheme
The post says the author has finally gotten Codex to run at 20x and is now trying to make spec decoding work for a TP2/4 PP2 hybrid schema. It reads like an engineering update on scaling and decoding strategy inside an agentic coding workflow.
The key signal is not a product announcement but a practical note on getting a high-throughput Codex setup working with a specific parallelism configuration.
