Anvisha's take

We have not scored the four readings by ear; press play and judge the voice yourself. What we measured: Turbo read the four scripts in 14 to 26 seconds of audio each and returned in four to seven seconds, for four cents across all four. That is half of Eleven v4's cost, but not much quicker: v4 took four to eight seconds for the same files. fal's endpoint returns a finished file, so the 150 ms to first speech ElevenLabs advertises, which is measured on a stream, is not what this test sees. Our readings ran from 14.0 to 26.4 seconds long, within a second of v4's on every script, with the same Sarah voice and stability.

Eleven v4 Turbo real output: the same 4 scripts every model gets

Meet the Ember mug. It keeps your coffee at exactly the temperature you choose, for up to ninety minutes, and it tells your phone when it's ready. Warm from the first sip to the last. Ember. Coffee, on your terms.

A pour-over works in four steps. First, rinse the paper filter with hot water so it doesn't taste of paper. Second, add the grounds and pour just enough water to wet them, then wait thirty seconds while they bloom. Third, pour the rest of the water in slow circles. Fourth, wait about three minutes for it to drip through. That's it: a cup that tastes like the coffee, not the machine.
