Cartesia is the company blog at cartesia.ai, writing about ai. Since 2024, 15 different Hacker News readers have linked it 16 times, most often “The on‑Device Intelligence Update”. No feed was found, so read it on the site itself.
Too few sampled comments (5) to say how often HN recommends it.?
Why HN links it
HN commenters mention Cartesia mainly as a company and product: a low-latency TTS API built on its Sonic model, and constant-time models for audio. The comments do not discuss its writing.
Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.
Cartesia builds real-time voice AI: production voice agents, lifelike text-to-speech, and accurate speech-to-text in 44 languages.

HN discussionThis is still four times more expensive than Cartesia ( https://cartesia.ai/ ) and three times more expensive than OpenAI's TTS API. In general, TTS APIs seem to run with much higher margins than LLMs from what I know.

HN discussionI work at Cartesia, which operates a TTS API similar to Play [1]. I’d be willing to venture a guess and say that our TTS model, Sonic, is probably SoTA for on-device, but don't quote me on that claim. It's the same model that powers our API. Sonic can be run on a MacBook Pro. Our API sounds better, of course, since that's running the model on GPUs without any special tricks like quantization. But subjectively the on…

HN discussionThe MAMBA [1] model gained some traction as a potential successor. It's basically an RNN without the non linearity applied across hidden states, which makes it logarithmic time (instead of linear time) inference with a parallelizable scan [2]. It promises much faster inference with much lower compute costs, and I think up to 7B params, performs on par with transformers. I've yet to see a 40B+ model trained. The rese…
