ChatGPT's big comeback: every new feature tested live

OpenAI had fallen behind Claude on agents and teamwork. With GPT-6 Astra, Space and GPT-6.1 Sol, they are back. In 90 minutes of live demos and Q&A, we tell you whether it is worth going back to: what already works, what is still limited in France, and what it changes if your teams use Claude, Copilot or Gemini.

Why it is worth it now

OpenAI had fallen behind. Now they are back.

In recent months, Claude, Copilot and Gemini have moved faster on agents and teamwork. With these four new releases, ChatGPT closes much of the gap. On the 27th, we test them in front of you to see whether it is worth going back to.

New
Demo · 11:00

GPT-6 Astra

Until now: on agents and code, Claude had the edge.

Now: OpenAI's new model moves back ahead on computer use, code and automation. Claude keeps the edge on expert reasoning.

Demo · 11:20

Space, Pages and @ChatGPT

Until now: ChatGPT was still an individual tool.

Now: share knowledge, co-write a document, call on the AI in Slack or Teams.

New
Demo · 11:40

Team automations

Until now: automating a team task required other tools.

Now: a request arrives by email, the AI prepares the next step, a human reviews before sending.

Demo · 12:00

GPT-6.1 Sol, Ultrafast, Pro 500

Until now: against Claude and Gemini, ChatGPT was no longer the obvious choice.

Now: new models. We look at which ones change the game, and what is available in France.

900+ companies have already trained their teams with AI Sisters

60,000 employees trained, from mid-sized firms to large groups. On Copilot, Gemini, ChatGPT and Claude.

An AI that acts in your tools: three questions to settle

With GPT-6 Astra, ChatGPT can use a computer and chain tasks together. Before opening it up to your teams, three questions arise.

✦
Issue 1

Data

Which company information can the AI access?

◎
Issue 2

Permissions

Which tools can it act on: Slack, Teams, your email?

✓
Issue 3

Human review

How do you know what it has done, and correct it if needed?

On the 27th, we show you how to decide, and you leave with the checklist for framing an agent.

90 minutes, four questions, live demos

We test in front of you, show the limits, and tell you what to do with it.
