• Mirai — On-device SDK (developer suite) for running highly optimized inference, fine-tuning, and operating LLMs and other deep learning models on the device. We aim to make it easy for developers to choose and route the query to the right model and deploy it to the device in a couple of clicks.Mirai is addressing a significant gap in on-device AIinference and training. Current cloud-based models face high latency, privacy concerns, and reliance on constant connectivity. Developers also struggle with high costs for personalization (e.g., $100M per year for 1M MAU) which is the most crucial pain point now and a core of our GTM. There’s no existing developer-friendly solution for on-device mobile AI, fine-tuning, and management. Our vision involves expanding from a robust SDK to include a developer console for model management, benchmarks, and fine-tuning.
