In practice, GPT-5.1 evolves ChatGPT from a simple powerful model into a more flexible, conversational, and controllable assistant—an interesting foundation for reliable agents and more premium user experiences.

- Designed for developers and products: With adaptive reasoning, Instant/Thinking separation, and Auto mode, GPT-5.1 clearly targets use cases like agents, copilots, support, internal tools, and premium services.

- Enhanced personalization: Tone and style options have been expanded, allowing for the configuration of an assistant that is warmer, more concise, or more educational, depending on your product or workflow.

- Clearer explanations: GPT-5.1 Thinking has been optimized to reduce jargon and make technical explanations more accessible while remaining precise for advanced users.

- Improved instruction adherence: The model better follows explicit instructions (format, length, style) and limits unnecessary digressions, which is particularly useful for code, documentation, or structured responses.

- Adaptive reasoning: GPT-5.1 adjusts its thinking time based on the complexity of the request, allowing for quick handling of simple tasks and deeper exploration of complex topics.

Exactly 😁😁!!

Opera Neon is available. Atlas is on macOS (requires ChatGPT Plus for the agent). Both redefine browsing. Both force you to choose: performance or privacy.

Which camp do you choose? Local or cloud?

→ The real question is: Do you want an all-powerful assistant that sees everything you do? Or a more modest agent that keeps your secrets at home?

→ For us devs: It's no longer "how do I code a website". It's "how will AI interact with my code/interface?". Opera reads your DOM. Atlas photographs your interface. The architectural implications are massive.

→ OpenAI ChatGPT Atlas: The agent lives in the cloud. It "photographs" your screen and sends it to OpenAI servers for processing. More powerful? Perhaps. But every click, every page, every action goes through their infrastructure. Power versus privacy.

→ Opera Browser Operator: The agent runs 100% locally. Zero cloud, zero external servers. Your banking data, your identifiers, your cookies? They stay on your Mac. The agent analyzes the DOM directly, executes your tasks in seconds. It's digital sovereignty incarnate.
