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.
