Company profile
researched Aug 2026Rebellions is a Korea-based developer of AI accelerator silicon and the systems built around it, aimed at inference workloads. Its flagship processor, Rebel100, is manufactured on a Samsung 4nm process and is specified at 2 PFLOPS of dense FP8 compute (1 PFLOPS FP16), 512MB of on-chip SRAM with 192TB/s of bandwidth, and 144GB of HBM3e memory at 4.8TB/s. Interconnect includes a 4TB/s UCIe-A interface implemented as three 1TB/s channels per chiplet, and 1.6TB/s Ethernet chip-to-chip connectivity, with an I/O die stated as available in the first quarter of 2027.
Around the chip the company offers a hardware stack that scales from board to data-center rack: RebelCard (a PCB assembly), RebelServer, RebelRack described as a turnkey inference rack for production deployment, and RebelPOD. Software is delivered through a company SDK, with a v0.11.1 release announced in August 2026, alongside developer resources such as a model zoo, SDK documentation, tutorials and publications. Positioning emphasizes inference efficiency, high utilization and low power at rack scale, and support for enterprise agentic AI use cases including document intelligence, email agents, cross-tool task running, and research workflows.
Business model
Rebellions sells AI inference hardware — accelerator chips, cards, servers, racks and pod-level systems — supported by a software development kit and developer resources, positioned for deployment by enterprises and AI data centers.
