3Wheels AI blog https://3wheels.ai/blog Field notes, research and opinions from the 3Wheels AI team on codebase licensing, healthcare data, physical AI, speech and the craft of human data. en Why private production codebases are the next frontier for coding models https://3wheels.ai/blog/codebase-data-frontier https://3wheels.ai/blog/codebase-data-frontier Codebase Data Public GitHub has been scraped to exhaustion. The next leap in coding-model quality comes from licensed, production-grade private repositories, with tests, reviews and real bug history attached. Tue, 01 Sep 2026 00:00:00 GMT Building healthcare datasets that survive regulatory scrutiny https://3wheels.ai/blog/healthcare-data-scrutiny https://3wheels.ai/blog/healthcare-data-scrutiny Healthcare AI De-identification is the floor, not the ceiling. What separates usable clinical data from a compliance liability is provenance: informed consent, patient-level linkage, and documented handling at every step. Sat, 01 Aug 2026 00:00:00 GMT Physical AI needs the real world, not just simulation https://3wheels.ai/blog/physical-ai-sensor-data https://3wheels.ai/blog/physical-ai-sensor-data Physical AI Sim-to-real transfer keeps hitting the same wall: the long tail of reality. Egocentric video, multi-sensor rigs, and real environments are how robotics foundation models close the gap. Sat, 01 Aug 2026 00:00:00 GMT Post-training is where models are won https://3wheels.ai/blog/post-training-rlhf https://3wheels.ai/blog/post-training-rlhf Post-Training Pre-training decides what a model knows; post-training decides what it is like to use. Preference data, expert demonstrations, and adversarial evaluation are the highest-leverage data you can buy. Wed, 01 Jul 2026 00:00:00 GMT Nine Indian languages, 37,000+ hours: inside our speech pipeline https://3wheels.ai/blog/indic-speech-pipeline https://3wheels.ai/blog/indic-speech-pipeline Conversational AI Hindi, Bengali, Marathi, Malayalam, Tamil, Gujarati, Kannada, Telugu, and Indian English: real conversational audio at a scale that makes voice AI actually work for a billion speakers. Wed, 01 Jul 2026 00:00:00 GMT Domain experts beat crowd labeling. Every time https://3wheels.ai/blog/annotation-domain-experts https://3wheels.ai/blog/annotation-domain-experts Data Annotation The cost difference between a generalist labeler and a trained specialist is small. The quality difference compounds through every epoch of training. Mon, 01 Jun 2026 00:00:00 GMT
