UK chip startup OLIX lands $312m to scale frontier inference

OLIX, a UK-based semiconductor and AI spot startup founded successful 2024, has secured $312m successful a Series B backing round, astatine a valuation of $3.3bn.

The fundraising saw information from Arm, Fundomo, Hudson River Trading, and idiosyncratic investors specified arsenic Netflix co-founder Reed Hastings.

Existing investors Plural, Hummingbird Ventures, Phoenix Court, Crane, Creandum and Transition each expanded their commitments successful OLIX during this round.

OLIX develops infrastructure for frontier AI inference.

The institution designs its systems extremity to end, including the chips, lasers, and the web that connects them. It delivers these systems arsenic implicit racks for high-demand inference workloads.

According to OLIX, existent approaches to gathering AI inference hardware are constrained by ratio limits.

The steadfast contends that ample information centres, which process tokens for AI models, mostly usage general-purpose chips throughout, alternatively of deploying specialised hardware for each signifier of computation.

OLIX has developed the X-1 platform, which unrolls AI models crossed aggregate chips, assigning each spot to absorption connected a azygous computational stage. Each spot is besides designed to stay flexible, without hardcoded exemplary architectures.

The strategy features a recently designed "slow and wide" optical interconnect, transferring information betwixt chips utilizing airy alternatively than copper, which OLIX says brings little latency and vigor costs.

The firm's archetypal chip, DX-1, is tailored arsenic a decode accelerator for the output signifier of ample AI models, particularly those with 100 cardinal parameters.

OLIX says DX-1 delivers implicit 10,000 tokens per 2nd per user, with higher throughput per watt than general-purpose chips, and that its plan omits precocious packaging and high-bandwidth representation to assistance debar proviso concatenation bottlenecks.

Funds from the Series B volition beryllium utilized to implicit DX-1 and grow OLIX's customized silicon platform, aiming for archetypal lawsuit entree successful the 2nd fractional of 2027.

The institution is recruiting unit for roles successful silicon, compiler, photonics, and systems engineering crossed London, Austin, Bristol, Toronto, and San Francisco.

In February, OLIX secured $220m successful Series A backing circular to enactment the improvement of AI chips. The backing round, led by Hummingbird Ventures, valued OLIX astatine $1bn.

As portion of the latest Series B backing announcement, OLIX has added Professor Nick McKeown to its committee of directors. McKeown is known for his enactment co-inventing software-defined networking, OpenFlow and P4.

He presently holds the presumption of Professor Emeritus of Computer Science and Electrical Engineering astatine Stanford University and is the 2025 Marconi Prize recipient.
