Why It Matters
Whisper was designed for batch transcription — upload a file, wait, get text. Voxtral was designed to transcribe as you speak.
Models like Voxtral and Kyutai were architected from the ground up for streaming inference. Words appear as you speak — no buffering, no wait times, sub-200ms from voice to text.
Older AI models are notoriously known to generate phantom text during silence — sometimes entire invented paragraphs. Modern architecture drastically reduces these hallucinations.
Cloud giants rely on legacy APIs. Our next-gen AI engines benefit from years of recent advances in transformer pipelines, quantization, and real-world audio datasets.
From older AMD GPUs to the latest M4 Macs and RTX graphics cards, our engines are dynamically tuned to run cross-platform right from your local desktop.
Out-performing their heavy legacy counterparts on independent benchmarks, testing flawlessly on Indian, Regional British, and Southern US accents.
Our full fleet of models process inference natively. Your microphone data doesn't move through the web; it is computed instantly in your own home.
We believe in honest technology. Big Cloud still excels in a few very niche areas:
Our take: For consumers, the decision is clear. Don't pay $17 a month for a SaaS product that simply runs the same open-weight AI algorithms you can now run privately for a fraction of the cost. Own your models. Own your hardware.
