The AI landscape has just shifted.
OpenAI, long the undisputed leader, has triggered an internal “Code Red” in the face of competition advancing at lightning speed: Claude Opus 4.5 (Anthropic) and Gemini 3 (Google).

Whichever model you choose, ChatGPT training for companies or Claude training for companies helps your teams make the most of it.

‍
Two models, two strategies… and the same result:
👉 ChatGPT's dominance is no longer guaranteed.

Claude Opus 4.5: the model that really worries OpenAI

‍

Claude Opus 4.5 is not just catching up with GPT-5.1:
it outperforms ChatGPT on several critical professional uses.

‍

1. Senior-analyst-level financial analysis

‍

Claude excels where companies most need rigour:
  • instant analysis of a balance sheet or P&L,
  • proactive risk detection,
  • multi-company comparison,
  • automatic creation of relevant ratios,
  • identification of anomalies in the data.

‍

👉 Result: an augmented analysis that is precise and actionable.

‍

‍

‍

2. Excel & data: the best on the market

‍

Claude is currently the best-performing model on data tasks:
  • building complete financial models,
  • pivot tables,
  • cleaning CSV files,
  • restructuring messy databases.
It anticipates, structures and automates like a subject-matter expert.

‍

3. High-level strategic summaries

‍

Claude reads 20 or 200 pages and produces:
  • the key points,
  • the risks & opportunities,
  • strategic recommendations,
  • a version ready for the leadership team (COMEX) or investors.

‍

Perfect for: finance, audit, consulting, private equity, legal.

‍

4. Enhanced security & precision

‍

Opus 4.5 reduces drift, follows complex instructions better and handles sensitive data carefully.
‍
👉 A natural fit for regulated environments.

‍

For developers: a leap forward

‍

‍

‍

‍

Anthropic is also targeting tech teams with:
  • the “effort” parameter — a quick answer or deep reasoning, depending on your needs,
  • improved Claude Code — more structured, more reliable,
  • integrations with Chrome and Excel to work directly in everyday tools.

‍

👉 Result: Claude becomes a complete technical assistant, not just a chatbot.

‍

‍

Gemini 3: the strategic threat

‍

While Claude dominates professional uses, Gemini 3 dominates another field:
‍
👉 global distribution.

‍

Google can switch on Gemini in:

‍

  • Android
  • Chrome
  • Google Search
  • Gmail, Docs, Sheets (Workspace)
As soon as Gemini improves, it can be pushed to billions of users.
And its performance (speed, versatility, robustness) now beats GPT-5.1 on several benchmarks.
‍
It is an existential threat to ChatGPT.

‍

Why OpenAI is activating “Code Red”

‍

Several critical signals are piling up:

‍

  • ChatGPT is losing ground — a drop in unique users (-6%)
  • Gemini 3 beats GPT-5.1 on many tests
  • Claude 4.5 is becoming the professional benchmark
  • Soaring infrastructure costs
  • Monetisation still immature

‍

OpenAI is therefore freezing:

‍

  • advertising,
  • AI shopping agents,
  • Assistant Pulse,
  • all secondary features.

‍

New top priority: improving ChatGPT.

‍

Faster.
More reliable.
More personalised.
More complete.

‍

OpenAI is going back to its core value because it no longer has a choice.
