The only software solution that transforms commodity NVMe SSDs into high-performance AI memory, solving the GPU memory bottleneck without hardware changes.
AI is evolving from text-based processing to multimodal—images, video, and beyond. Memory requirements are exploding exponentially.
Text-based AI like ChatGPT and Claude requires tens of gigabytes. But as AI services evolve to process images (DALL-E, Midjourney, Stable Diffusion) and video (Sora, Runway, Gemini Video), memory requirements explode by 100x to 1,000x.
This isn't a gradual change—it's an exponential leap that current HBM-centric memory architecture simply cannot handle.
Large Language Models are fundamentally stateless—they "forget" everything after each response. To maintain conversation continuity and context, systems must store KV Cache: Key-Value vectors that serve as mathematical summaries of all previously processed tokens.
Every time you continue a conversation, the AI needs to reference these vectors to understand what was discussed before. Without KV Cache, the model would need to re-compute the entire conversation history from scratch—a massive waste of GPU resources.
KV Cache is ephemeral by nature—it's only needed for the duration of a session. Once a conversation ends, this temporary data should be discarded or archived. But current systems treat all data the same, causing massive inefficiencies in storage and memory management.

Intelligent Hot/Cold separation
The solution isn't more expensive HBM—it's intelligent software that leverages high-capacity NAND Flash as extended memory. By automatically separating Hot Data (frequently accessed, active) from Cold Data (archived, infrequently accessed) and optimizing placement, we unlock TB-scale AI memory at a fraction of the cost.
Frequent read/write, kept in fast tier
Load on demand, stored in NAND Flash
As AI models scale exponentially, memory has become the critical bottleneck that hardware alone cannot solve.
High-performance GPUs sit idle, waiting for data. Multi-million dollar H100 clusters operate at a fraction of their potential because memory cannot feed them fast enough.
56% GPU Idle Time100B+ parameter models require 1.6TB+ memory for training, but even the most advanced GPU (H100) has only 80GB HBM. A 20x gap that cannot be bridged by hardware alone.
20x Memory ShortageHBM costs $10-15/GB compared to $0.10-0.20/GB for SSD—a 100x price difference. Even with unlimited budget, HBM is sold out until 2026.
100x Price GapAI workloads generate chaotic random I/O patterns causing Write Amplification Factor (WAF) of 3.0+, triggering frequent garbage collection and catastrophic performance drops.
