Training got GPUs. Decode got fast memory. Sparsity gets Sparxity.
Frontier AI models are moving away from treating every token equally. They increasingly activate only the parameters, memory and context a token needs, and leave the rest untouched. Each new form of sparsity is finer than the last, and further from what today’s hardware was built for.

Models get smarter for the same compute as they get sparser. But incumbent hardware was built for dense computation: the sparser the model, the more routing and data-movement overhead it adds, so model builders keep sparsity coarse. Here’s what Sparxity turns it into.
On incumbent hardware, a smarter model costs more to run. On Sparxity, the sparser the model, the smarter it gets and the less each token costs.
Model builders go finer-grained across experts, memory and attention, and build smarter models.
Hyperscalers, neoclouds and cloud providers serve them faster, at a fraction of the cost per token.
- Faster per user
- Long agentic sessions stay fast
- More per megawatt
- Skipped work burns no power
- More per dollar
- And more still as models get sparser
