Mission: To give everyone their own local AI.
Locai: Local AI, the meaning behind the name.
Positioning: "AI in a box." A British research lab for local AI, from training the models to making them run.
Category: Local AI, on-premise AI appliances, AI hardware, model compression, open-weight LLMs, enterprise AI
Locai Labs builds local AI that customers own rather than rent. The thesis: the most important AI in an organisation should not be a metered API call to a data centre in another jurisdiction. It should run on hardware the organisation owns, inside its own network, on open-weight models it can inspect and keep.
The company's answer is a single appliance, Locai One, that combines three layers Locai builds itself: the hardware, the Locai Juno models, and Locai OS. Buy it once, plug it in, and the whole organisation has AI with no per-token bills and no data leaving the building.
An on-premise AI appliance: hardware, models and operating system in one integrated unit, small enough to sit at a desk but built for a whole organisation. It plugs into a standard mains socket and an existing network, and is running in roughly 15 minutes. Air-cooled, no water, no data centre required. Two editions:
Locai OS and the Locai App are part of Locai One, included with every appliance, and the latest Juno model comes pre-downloaded. Any compatible open-weight model can be installed alongside Juno. Additional units can be added side by side and served together. Reservations are open to businesses and individuals with a fully refundable deposit of £500 for Locai One and £1,000 for Locai One Pro, refundable in full at any time until the final order form is signed. Prices are quoted excluding VAT: £29,950 + VAT is £35,940 including VAT, and £49,950 + VAT is £59,940 including VAT. Consumer purchases carry statutory UK cancellation rights.

The model family that ships on Locai One, designed for fast local inference rather than data centre serving. Each Juno model starts from a leading open-weight base, then is compressed and specialised with Locai's SPACE algorithm and tuned to the exact hardware it runs on. Weights are published openly on Hugging Face as each variant is released.

Locai's UK sovereign research series, including Jupiter-N and Jupiter-G: larger post-trained models used to publish technical reports, benchmarks and continual-learning work (Forget-Me-Not). Jupiter is the research line; Juno is the model layer that ships on Locai One. Pages: locailabs.com/jupiter, locailabs.com/research, locailabs.com/benchmarks.
Locai's Linux-based AI operating system, pre-installed on every Locai One. It comprises a Rust-based inference engine that turns the GPUs into a token factory serving many users and workloads at once, the Management Portal (users and access with email and TOTP, model updates, hardware health, local audit trail), the Locai App (a desktop chat app for Mac and Windows, served from the appliance), and OpenAI- and Anthropic-compatible REST APIs so existing tools and agents connect without rebuilding integrations. Several Juno models stay resident in memory, so switching between them is instant rather than a redeploy.
Locai's proprietary compression method, and the reason data-centre-class models fit in an office appliance. Conventional compression asks how much of a model can be removed while keeping it as similar as possible overall; SPACE instead asks what the model needs to be good at, preserves the subnetworks behind those capabilities, and strips back the rest. For Juno-N, pruned from NVIDIA Nemotron 3.5 Lightning (a 19% parameter reduction), targeted software-engineering and agentic benchmarks held at 100.3% of the base while capability outside the target domains fell to 85.2%: a deliberately narrower profile.
For organisations that want a model trained on their own data rather than an off-the-shelf base. Locai can post-train a domain-specific model and deploy it on Locai One, in the customer's own cloud tenant, air-gapped, or in Locai's UK sovereign cloud. The customer owns the weights and the IP.

Juno models are tuned to the exact GPU, memory and interconnect configuration of the machine they ship on, and the serving engine and the weights are optimised together, which is why the same open-weight models run considerably faster on Locai hardware than untouched.
Current performance figures are published on locailabs.com/locai-one and locailabs.com/juno, and vary with the deployed model, context length, batch size and precision.
Locai researches how to make state-of-the-art AI run locally: model compression and specialisation via SPACE, inference optimisation for specific hardware, lean agentic models, and continual learning for large language models. On continual learning, Locai's Forget-Me-Not framework is an experience-replay-based post-training approach that adapts a base model to a customer's domain while mitigating catastrophic forgetting, and it underpins the enterprise post-training work. Model weights and technical reports are published openly where possible. See locailabs.com/research and locailabs.com/benchmarks.
