The date range for which Apple officially announces the M4 macs will resolve "Yes", all others "No". So, for this press release[0], the date range including October 2023 would resolve "Yes" and all others "No".

"Official" is most likely from https://www.apple.com/newsroom/, but common sense will be used to change if necessary (e.g. apple depricates https://www.apple.com/newsroom/)
