Artificial intelligence research has gained significant momentum in recent years. In this development process, the performance of the models is evaluated not only with their response speeds, but also with their success in complex tasks. Developed by Anthropic, the Claude 4 series offers a remarkable example in this respect. Especially the developments in coding and logical problem solving points to a different point among artificial intelligence models.
These new models, named Claude Opus 4 and Claude Sonnet 4, have a structure that differs from previous Claude versions. According to the company, Claude Opus 4 is the most advanced model so far. This system, which can operate uninterruptedly for up to seven hours, is specially optimized for long -term tasks. Thus, it becomes more reliable in workflows that require continuity such as software development, analysis and data processing.
The Claude 4 models differ not only in terms of their term of office, but also in terms of output quality. In particular, the success of code writing tasks, GPT-4.1 and Gemini 2.5 Pro, such as the leading systems of the sector. These comparisons are based on Anthropic’s own benchmark tests. It is emphasized that the model is more successful not only in coding but also in tasks that require external vehicles.

Claude 4 models work more consistently in long -term cognitive tasks
Claude Sonnet 4 was developed as a more accessible option. This model, aimed at end users and general tasks, has replaced Claude 3.7 Sonnet. However, it is stated that it includes serious developments in logical reasoning and coding. In addition, it is stated that it uses less shortcut methods and can work more stable in long -term tasks.
The “Thinking Summary” feature, which is included in both models, makes the process of the formation of the responses more transparent. With this feature, users can easily follow how Claude reached a result. In addition, the “expanded thinking” mode at the beta phase allows the model to change the behavior of the model according to different types of task. In this way, more sensitive results can be obtained in tasks based on vehicle use.
Claude 4 models are accessible via the Amazon Bedrock, Anthropic API and Google Cloud’s VerTex AI platform. In paid plans, full access to Opus and Sonnet 4, free users can only benefit from Sonnet 4. This distinction makes it possible to monitor a customized access strategy for different user profiles.
The Claude Code vehicle, which was developed specifically for the coding field, was also available for general use with this model series. This tool, which works with a command line -based, allows developers to interact directly with Claude models. This vehicle, which is presented as a limited preview in February, is now available to appeal to a wider audience.
The way Anthropic follows the Claude 4 series is based not only on increasing model power, but also on a sustainable development cycle. The company says that it will release model updates more frequently from now on. This decision is critical to keep up with the increasingly accelerated change in the field of artificial intelligence.
The sectoral effects of Claude 4 models should be evaluated not only in terms of technical, but also in terms of use. This performance increase in coding tasks paves the way for new opportunities in terms of productivity for developers and engineers. It also offers a more determined structure in terms of reliability and data consistency in long -term tasks.
Nevertheless, it should be remembered that tests are based on Anthropic’s own comparisons. Independent comparisons may be needed to make such assessments healthier. However, in the light of the available data, it can be clearly seen that Claude 4 models offer a significant breakthrough especially in terms of technical competence and quality of tasks.
