8.5x Faster Speech-to-Text: From 429ms to 50ms on a Single GPU
My STT journey started with Whisper. One of Freya's STT models was a fine-tuned Whisper Large-V3. I optimized it with TensorRT, got it to 130ms, around 94x realtime. Solid, but we hit a wall. The…
How do you politically manage “LLM-forward” cultures that incorrectly leverage power over the value-based design process?
What happens when someone generates a front-end comp for you and says this must be the way? Of course this hasn’t happened with any of our clients, since this is unallowable into the field. But we’ve…
