Introduction: Recently Launched

"In a single week, three tech giants launched their latest AI models. For businesses looking to automate, this means: choose or fall behind."

On November 24, 2025, Anthropic unveiled their latest AI model: Claude Opus 4.5. This model is immediately positioned as the new standard for coding, advanced agents, computer use and everyday tasks such as research, presentations and spreadsheets. The release comes in the middle of the competitive battle with comparable introductions from Google's Gemini 3 Pro and OpenAI's GPT-5.1. Yet Opus 4.5 offers a unique combination of performance, price and ease of use that sets it apart from the rest.

Why Anthropic's latest model is shifting the benchmark

"With Opus 4.5, Anthropic is raising the bar for enterprise AI. Excelling in speed, safety and documentation: Opus 4.5 is tailored to realistic business needs -- not just academic benchmarks."

What makes Claude Opus 4.5 so special?

1. Outstanding performance in code, agents and computer use

Claude Opus 4.5 is the first AI model to achieve a score of 80.9% on SWE-bench Verified -- a breakthrough in programming performance. For digital agency tasks such as spreadsheets, presentations and autonomous agents in web and app operation, Opus 4.5 also sets the pace.

2. Significant price reduction: powerful yet affordable

With rates of $5 per million input tokens and $25 per million output tokens, Opus 4.5 makes powerful AI accessible not only for large enterprises, but also for SMEs.

3. Integration with existing tools

Immediately deployable via:

This broad integration enables rapid deployment in virtually any business workflow.

4. Safety and transparency

Claude Opus 4.5 operates at a strict security level and is designed to provide protection against misuse, manipulation and data breaches. This makes it suitable for organizations with high compliance and privacy requirements.

Practical: The benefits for organizations

  • Fast, high-quality research automation
  • More efficient software development thanks to GitHub Copilot integration
  • Automated reporting, domain management and monitoring
  • 24/7 customer service, security audits and compliance

Users report workflows that have become up to 30% faster and more stable -- especially for repetitive, complex tasks. Integration is quick and rarely requires major changes to existing IT infrastructure.

How does Opus 4.5 perform compared to the competition?

Model SWE-bench Verified HumanEval (Code) MMLU Agentics
Claude Opus 4.5 80.9% ~95% ~90% best in class
Google Gemini 3 Pro 76.2% ~85% ~92% comparable
OpenAI GPT-5.1 76.3% ~95% ~90% comparable

Claude Opus 4.5 is the first model to break through the 80% barrier on SWE-bench Verified. This benchmark tests whether AI can independently solve bugs in real software projects, including finding the right files and writing working code. This puts it roughly 4-5 percentage points ahead of both Gemini 3 Pro and GPT-5.1.

On HumanEval (shorter programming problems), all three models perform at a comparable level; this benchmark has become less differentiating now that virtually all frontier models score above 90%.

On general knowledge and reasoning (MMLU), the differences are minimal. Gemini 3 Pro scores slightly higher on scientific reasoning tasks such as GPQA Diamond.

Benchmark data sources

Getting started with Opus 4.5
