Fractile
A British chip startup, spun out of Oxford in 2022, building inference chips that keep model weights on the same silicon as the compute.
Fractile was founded in 2022 by Oxford PhD Walter Goodwin and builds chips for inference, meaning the job of actually running an already trained AI model to answer a question. Ordinary AI chips store the model’s numbers in separate memory chips and fetch them across a connection every time they are needed, which is slow and burns a lot of power. Fractile puts compute and memory on the same piece of silicon using SRAM, so there is far less fetching to do.
The company claims this can run large language models up to 100 times faster at 90 percent lower running cost. Those are its own figures with no independent benchmark behind them, so treat them as a pitch rather than a measurement. In August 2026 Fractile was reported to be raising around 600 million dollars at a 6.5 billion dollar valuation after an initial agreement to supply Anthropic with roughly 250 million dollars of chips. The chips are not expected to ship until 2027.
