add fast mode toggle by pash-openai · Pull Request #13212 · openai/codex

pash-openai · 2026-03-02T04:07:16Z

add a local Fast mode setting in codex-core (similar to how model id is currently stored on disk locally)
send service_tier=priority on requests when Fast is enabled
add /fast in the TUI and persist it locally
feature flag

Would be really great if fast mode would be available on plus/team tiers with significantly lower quota! Thanks for considering that in advance

            SlashCommand::MemoryDrop => "DO NOT USE",
            SlashCommand::MemoryUpdate => "DO NOT USE",
            SlashCommand::Model => "choose what model and reasoning effort to use",
+            SlashCommand::Fast => "toggle Fast mode for supported models",


should this be conditional?
