fx 0.0.13
Ultrafast lands on supported OpenAI models through AI Gateway (a higher-priced inference tier) โ launches up to 23ร faster, shell calls up to 8.6ร faster, exits up to 44ร faster in matched benchmarks; subagents and ACP sessions support it. Breaking: terminals launched through the shell tool now stop when fx exits, and new libfx checkpoints cannot be restored by older versions.
