ByteDance
ByteDance runs a large-scale hybrid architecture with proprietary cloud-native data and streaming systems (ByteHouse, ByteHTAP, ByteMQ/Flux) atop commodity storage and compute, tightly integrated with recommendation and multimodal AI stacks for products like TikTok/Douyin and robotics.[1][3][6][7][8][9] Real-time streaming (Kafka/ByteMQ), HTAP, and on-device AI infrastructure (Pitaya) form the core substrate for online training, inference, and global content delivery.[1][2][3][8][10][11]

FAQ
Does ByteDance use a foundational AI model?
ByteDance uses Doubao (ByteDance foundational LLM, Chinese & international markets), Monolith (large-scale recommendation / ranking model family), Astra-Global (multimodal large language model for robot navigation) (Native (own / self-hosted weights)).
What cloud does ByteDance run on?
ByteDance runs on Hybrid.
What database does ByteDance use?
ByteDance uses ByteHouse (cloud-native data warehouse, ClickHouse-derived)[6], ByteHTAP (internal HTAP system)[9], HDFS (offline storage in recsys pipelines)[8], Kafka / ByteMQ (messaging + streaming backbone, storage/compute separated)[1][8], Redis / RedisCell (caching, counters)[10], MySQL (common OLTP store, prior record corroborated)[8].
How close does ByteDance run to the foundational model?
ByteDance is Native (own / self-hosted weights) — close to the metal, so cheaper tokens and more control over outputs.
