[Fuse Energy @fuseenergy]

Fuse Energy is entering AI compute.

Introducing Fuse Compute: dedicated NVIDIA GPUs in UK data centres hosted and powered by Fuse. Available to businesses globally.

Sensitive customer data needs a clear answer to where it runs and who it runs next to.

With Fuse Compute, it’s bare-metal GPU nodes reserved for you alone, hosted in the UK, under UK jurisdiction.

The hardest part of scaling compute today is getting power to the site, which is the part we already do. With 142MW of data centre connections in the pipeline across 15 projects, compute is our next step. We have the infrastructure to deliver this to businesses globally.

Our first 128 NVIDIA GPUs are due online in December 2026, followed by 1,024 in Q2 2027.

Reserve your capacity now.

@texhnogatsby Security is one of the five core investment themes, and half of the current SovAI procurement challenges are on security solutions. All at https://t.co/LThLIb8ZE5.

[James Wise @Jameswise]

If it wasn’t obvious already we’re in a completely new paradigm of cyber vulnerabilities.

Product teams at Cloudflare, Mozilla, Chrome, Safari etc are doing incredible work keeping up - but wow we need more and better defensive cyber models to harden applications and the web yesterday.

It is astonishing to read in the @thetimes today an Op-Ed from @parismarx saying AI hasn’t changed anything! Head in the sand is not a strategic option.

[Cloudflare @Cloudflare]

Following the discovery that eight eMudhra intermediate certificates use weak keys, Cloudflare is deploying mitigations and releasing client updates. We explain the impact, our response, and what customers and developers should do next. https://t.co/lYGxHb3PHS

[James Wise @Jameswise]

@AxleLandt It can get better

[NCSC UK @NCSC]

The NCSC is encouraging UK organisations to prepare for immediate updating of systems using PHP. Where immediate remediation is not feasible, organisations should consider taking the system offline until it can be fully mitigated.

@Jaw9c Nice to know I haven't been overtaken by the frontier on posts yet...

[James Wise @Jameswise]

Now that we've cracked Navier-Stokes and flying cars, there is only one true, super-human technological challenge left - lowering British electricity bills.

And Fuse seem to have cracked it! An affordable home battery & solar system which means lower bills and more energy independence at home, and at scale more capacity on the grid.

Hi there Jules, another impressive release from @alanchanguk , @charlesorr and the phenomenal team @fuseenergy.

[Fuse Energy @fuseenergy]

Meet Jules by Fuse Energy.

An intelligent energy system for your home. Plug in and autopilot does the rest.

It learns your habits, stores power, trades the excess and continuously lowers your bills.

Solar and storage is now for everyone.

@vinousali @thomasforth Stopping Tom getting scammed is a national security priority.

[Sovereign AI @UKSovereignAI]

We’re delighted to announce our investment in Augur.

Augur is building technology that can help security teams find information faster and respond sooner, with applications across public safety, serious crime and critical infrastructure.

Augur is already working on capability to prevent attacks by hostile states on Britain’s critical national infrastructure. They’re also partnering with @TfL to help identify and detect sexual offending on the transport network, behaviours that disproportionally impact women and girls.

We’re excited about the potential to help keep people safer, give investigators valuable time back, and spot threats before they become more serious. The Augur team is tackling an incredibly important problem and building the solution here in Britain.

Read our blog below for more information on Augur’s technology.

“okay, so what? it’s just math.”

no, you don't get it.

here’s what OpenAI’s math breakthroughs could eventually help make possible in the real world:

Vlasov–Maxwell → stronger foundations for fusion research, whose ultimate prize is virtually limitless clean energy to power civilization

Calderón’s Problem → portable body scanners using electrical signals, making medical imaging cheaper and easier to access

Maximum-Cardinality Matching → faster searches for compatible kidney swaps across large donor pools, helping hospitals coordinate lifesaving transplants

Inverse Elasticity Problem → scans that map tissue stiffness, helping doctors locate suspicious growths inside the body

Mumford–Shah Conjecture → better tools for spotting tissue changes in brain scans, helping doctors identify signs of disease

Bose–Einstein Condensation → stronger foundations for quantum sensors that could help vehicles navigate without GPS

Simple Stochastic Games → better safety checks for self-driving cars and robots before dangerous mistakes reach the real world

Matrix Multiplication → cheaper AI and bigger scientific simulations using the same computers

Edit Distance → faster DNA comparisons, helping researchers study genetic changes linked to disease

The k-Server Problem → robots that waste less movement and energy, making warehouses more efficient and goods cheaper to move

a reminder that math is the foundation of science.

so accelerating mathematical discovery could compress centuries of scientific progress into years.

insane timeline to be alive for!

@davidgelberg Awesome

[Mistral AI @MistralAI]

Meet Mistral Large 4, aka Le Chonk.

• 1T parameters, natively multimodal. 49B active.
It is the best open weights model from US or Europe on aggregated benchmarks.
• State-of-the-art on critical workloads, including cyber defense, manufacturing and finance and it surpasses closed frontier models on visual grounding.
• Forged in Europe end-to-end and is deployable from Europe via our own Mistral Cloud infrastructure.
• Available to all via API today. Working with cybersecurity partners privately.

Open weights release end of October.

[James Wise @Jameswise]

The reports of open-weight’s death have been greatly exaggerated again, it seems.

An astonishing first model release, open-weight and from an 🇺🇸 & 🇬🇧 based team.

Congrats @real_ioannis, @sahnihim and all @reflection_ai.

[Reflection @reflection_ai]

Introducing Beam: a highly efficient agentic open model with 501B total parameters and 23B active.

- Frontier reasoning efficiency
- Advances the Western open frontier on coding & agentic tasks
- Trained end-to-end from scratch

Full weights release this month.

[James Wise @Jameswise]

A lot in here I agree with:

- The public discussion seems to be mostly on AI hypotheticals. But there are serious and present opportunities and challenges facing the UK today.
- AI capabilities are hard power in the same way our military, energy and infrastructure are, and should be treated as such.
- While Brits should have access to the best services in the world wherever they’re built, we must have more of these capabilities here at home as well to ensure resilience and leverage.

The @UKSovereignAI Unit was set-up with much of this in mind - kind of David to give us a mention, but we’re only a small part of the solution.

[Financial Times @FT]

The UK government needs to do more to support its own AI companies https://t.co/hOWWv8xhbu

[James Wise @Jameswise]

Some quick ( and free! ) wins here for the Government to look at to support British researchers and engineers.

[Inherent @inherent_labs]

1/ Today we’re launching an open letter calling on the government to end unfair restrictions that stop Britain’s best switching jobs or starting companies.

UK AI companies that have raised $5bn agree: our best should be free to start and scale. 🧵

@downingstreet @biztradegovuk

[James Wise @Jameswise]

Security is the most important frontier.

@balderton, over half the investments I’ve led in the last year have been in cyber. And we should be doing even more.

Great to see ARIA support researchers from day one.

[ARIA @ARIA_research]

AI-enabled cyber attacks are getting faster + going further. But what if AI-enabled formal methods could make high-assurance cyber defence practical at unprecedented speed + scale? We’re funding eight teams with £22m to test that idea. Meet them here: https://t.co/kuXU3EuUsg
