Thanks for the help with the homebrew update. This is a great idea! Do you think there's a way to do this based on the latest git value or something automated? We're calling cli commands here

WhisperKit/Sources/WhisperKit/Core/Utils.swift

Lines 122 to 138 in c829f9a

	extension Process {
	static func stringFromTerminal(command: String) -> String {
	let task = Process()
	let pipe = Pipe()
	task.standardOutput = pipe
	task.launchPath = "/bin/bash"
	task.arguments = ["-c", "sysctl -n " + command]
	task.launch()
	return String(bytes: pipe.fileHandleForReading.availableData, encoding: .utf8) ?? ""
	}
	static let processor = stringFromTerminal(command: "machdep.cpu.brand_string")
	static let cores = stringFromTerminal(command: "machdep.cpu.core_count")
	static let threads = stringFromTerminal(command: "machdep.cpu.thread_count")
	static let vendor = stringFromTerminal(command: "machdep.cpu.vendor")
	static let family = stringFromTerminal(command: "machdep.cpu.family")
	}

which seems to work well, perhaps current version could be a computed property based on git describe --tags

@chenrui333 Updated this PR with the built-in version param on CommandConfiguration. I've updated the formula argmaxincbot/homebrew-core#1 such that it will use the tag from the URL to replace this placeholder, which will then be available in the build that homebrew makes. This way the version will always be up to date and self contained in the homebrew formula, lmk what you think

Tests are passing, will merge if there's no objections in a bit.

yeah, if we can make sure version is good as part of the release script, all good to me
