Anthropic new model, Claude 4, includes Claude Opus 4 and Claude Sonnet 4, its most advanced AI model to date, which strives to set benchmarks in AI, particularly in coding, reasoning, and execution autonomously.

What Is Claude Opus 4?

Claude Opus 4 is built for developers and engineers and towers over GPT-style models in its ability to reason through complex problems and perform long-duration tasks.

In testing, Claude Opus 4 has performed autonomously for roughly 7 hours, a feat unseen in earlier models, including OpenAI’s GPT-4.1, which achieved around 3 hours in software engineering benchmark tests.

Claude Sonnet 4 is designed for broad use, with enhancements in coding ability and accuracy over Sonnet 3.7. Like its predecessors, both models are “hybrid” and can produce semi-instant responses, or go through the motions and process to respond to definitions and examples step-by-step for thorough answers.

A key aspect of Claude 4 is its “extended thinking mode,” which allows the AI to reflect on its answer before responding, which tends to improve its performance on tasks that require complex reasoning.

These improvements position Anthropic new model, Claude 4 as a strong contender in the AI space, along with providing developers and businesses with powerful tools for many applications.
