GPT-6 Astra + AI outside the London bubble

Welcome back!

Published 28th September by Josh Page, Growth & Enablement Lead.

In our post-summer update:

  • GPT-6 Astra and Claude Opus 5.5 - the frontier moves again.
  • AI in the industries that make things: security, bridges, warehouses, ports.
  • Field notes: GP heads to the US to train two Access Holdings portfolio companies.
  • Agent Builder + Mastering Claude Code, rollouts so far
  • Next Friday: Mastering ChatGPT and Mastering Claude, with funded scholarship places.

Let’s dive in…


GPT-6 Astra and Claude Opus 5.5: the frontier moved twice this month

Two big model releases in three weeks. OpenAI dropped GPT-6 Astra at the start of September and Anthropic followed with Claude Opus 5.5 last week.

Astra one-shots playable 3D games from a single prompt. In business, the more relevant capability is computer use: Astra operates Blender, Unity, SolidWorks and Excel directly, clicking the buttons a person would.

Opus 5.5 matches the previous frontier at 40% lower cost (per Anthropic pricing, September 2026). At $4 per million input tokens versus Astra’s $10, Opus 5.5 may be the frontrunner for business adoption at scale.

Worth noting the timing: On 12 September, Dario Amodei (CEO of Anthropic) published an essay calling on labs to pace the frontier, with the heads of OpenAI, xAI and DeepMind publicly agreeing. Anthropic shipped Opus 5.5 ten days later.

Staying current is harder than ever.


Security Systems, Bridges, Warehouses, Ports… AI helping industries that make things

Learning and Work Institute put the prize this week at £80 billion added to the UK economy by 2035 if we get AI upskilling right. Their focus is knowledge workers in finance and professional services.

We'd argue there is also a huge untapped opportunity outside the London bubble - AI training for teams in manufacturing and logistics businesses.

Recent rollouts we’ve done in these industries:

  • CLD Security Systems: the UK’s largest maker of perimeter security fencing
  • Acrow Bridge: modular bridges for infrastructure and defence
  • BITO Lagertechnik: global warehouse and intralogistics storage systems
  • Community Network Services: technology behind global port operations

Four traditional industries. One shared question: how do we use AI to work smarter?

All started with our AI Strategy and then rolled out our Mastering AI training to 100+ seats, uncovering great AI use cases across their teams along the way.


Field notes: Our team returns to the USA

Tom (our founder) and Aaron (our lead instructor) spent time in the US this summer, running Mastering Claude for Spotless Brands in Chicago and Playfly Sports in Philadelphia.

Both are portfolio companies of Access Holdings. We first met both at Access Holdings’ ACE Programme in Baltimore earlier this year, and the follow-on has been growing since.

The pattern is one we’re seeing more often: PE firms bringing us in to help their operating companies use AI to create value, in addition to their investment and fund ops teams.

Playfly are also the first client we’ve seen with a basketball court in their office:


New: Mastering Claude Code and Agent Builder

The pattern that we keep hearing: teams asking to build Agents faster than their IT departments will let them.

These have been landing well with teams over summer. Blue Light Card has put their engineering team through Mastering Claude Code, with a well-known sustainable climate fund up next. Agent Builder ran recently with family office RCL Partners, and a leading European economics consultancy is on for November.

If your team wants to understand what’s possible with Agents or Claude Code (or wants help making the case to IT), drop us a line: hi@generalpurpose.com


Coming up: Open Enrolment training with funded graduate places

Two half-day online sessions coming up:

  • Mastering Claude: Friday 2 October, 9.30-13.30 BST. Book here.
  • Mastering ChatGPT: Friday 13 November, 9.30-13.30 GMT. Book here.

For every corporate team we train, we fund scholarship places for graduates and students whose early careers are most exposed to AI’s impact on the labour market.

If that’s you, email hi@generalpurpose.com for a 100% discount code. If you know a graduate or student it applies to, please forward this on.


Until next month…

As ever, drop us a line at hi@generalpurpose.com if you want to talk about any of the above, or forward this on to a colleague who’d find it useful.
