DeepMind introduces Gemini 2.5, a new generation of models designed to think before answering. What does that mean for you — whether you're writing emails or part of a dev team automating complex tasks? I'll explain it clearly and practically. (deepmind.google)

What is Gemini 2.5

Gemini 2.5 arrives as a family of "thinking models", where the initial release is Gemini 2.5 Pro Experimental. It's not just a speed or size upgrade: DeepMind says this model reasons better, incorporates context more accurately, and ranks highly in human preference tests. (deepmind.google)

Can you picture an assistant that doesn't just reply but evaluates several lines of thought before choosing its answer? That's exactly what this generation aims for.

Performance and reasoning

The core bet is improved reasoning. Gemini 2.5 Pro shows superior results in math and science tests like GPQA and AIME 2025, and reaches 18.8% on a benchmark called "Humanity's Last Exam", designed to probe the limits of human-like reasoning. If you deal with problems that need many logical steps, this could make a real difference. (deepmind.google)

Beyond classifying, the AI tries to analyze, connect context and draw conclusions; that's what reasoning means here.

Developers and code: a big leap

If you write code or build autonomous agents, this matters to you. Gemini 2.5 Pro climbs substantially on coding tasks: in agentic code evaluations like SWE-Bench Verified it hits 63.8% with specific configurations, and it can generate visual apps or transform code from simple prompts. Imagine asking "make me a simple game in one line" and getting a functional executable as a starting point. (deepmind.google)

That kind of capability speeds up prototyping and lets small teams create complex demos without rewriting everything from scratch.

Multimodality and context: working with huge data volumes

Gemini 2.5 inherits Gemini's multimodal skills and brings a very large context window: the Pro version starts with a context window of 1,000,000 tokens (and DeepMind announces 2,000,000 tokens soon). That means you can feed long code repositories, extensive documents, or multimedia sequences without losing coherence. The model also handles text, audio, images, video and code repositories. For teams that combine diverse data into a single workflow, this simplifies a lot. (deepmind.google)

Where you can try it and costs

The initial Gemini 2.5 Pro Experimental is available on Google AI Studio and in the Gemini app for Advanced users; its arrival on Vertex AI is announced for the coming weeks. DeepMind says they will share pricing options and scale limits in the following weeks. If you're a developer or product lead, it's worth starting tests now to understand costs and constraints.

What this really means for you

• For content creators: better responses with wide context and less need to split prompts.

• For developers: faster prototyping and agents with greater autonomy on complex tasks.

• For companies: the possibility to consolidate multimodal flows (text, audio, video, code) in a single model, though you'll need to evaluate costs and security.

A concrete example: imagine a consultant uploading a project's entire history — emails, PRs, documentation — and asking the model for a launch plan with risks and a checklist. With 1,000,000 tokens that task stops being a manual collage and becomes a single coherent request.

Final reflection

Gemini 2.5 isn't just another number in the model race; it's a step toward systems that combine deep reasoning, multimodality and massive context windows. Will you use it to automate routine tasks, speed up development, or explore new products? The answer depends on your situation, but DeepMind's invitation is clear: try it, give feedback and prepare responsible integrations.
