Internal screenshots circulating on social media show that Anthropic is conducting internal testing on its next-generation large language model, Claude Opus 4.1. According to the leaked information, the model's internal codename is "claude-leopard-v2-02-prod," and the official slogan emphasizes a significant improvement in problem-solving capabilities.

The leaked information reveals the model's positioning

From the circulated screenshots, it appears that Anthropic has used the slogan "Opus4.1 is here - Try our latest model for more problem solving power" in its internal testing interface. This statement clearly points to the new model's focus on optimizing reasoning and complex problem-solving capabilities.

The internal codename "claude-leopard-v2-02-prod" is also worth noting. The name "leopard" suggests that the model may have faster response speeds and more acute analytical abilities. The "v2-02" indicates that this is the second major iteration of the version, and the "prod" suffix means it is a production environment test version, implying that the model may be close to an official release.

Clear technical upgrade direction

From the wording of the slogan, the core upgrade of Claude Opus 4.1 focuses on "problem solving power." This positioning aligns closely with the current trends in the AI industry — after the release of inference models such as GPT-o1 and DeepSeek-R1, major AI companies are all enhancing their models' logical reasoning and complex problem-solving capabilities.

Anthropic's decision to launch a new model with enhanced reasoning capabilities at this time is clearly aimed at maintaining a technological edge in the competitive market. Especially in the context where OpenAI's o-series models and other competitors continue to release enhanced versions, the upgrade of Claude Opus 4.1 seems particularly timely and necessary.

Technical direction during the internal testing phase

From the version number "v2-02-prod," it is clear that this model has undergone multiple rounds of internal iterations. Typically, AI companies conduct extensive testing and optimization internally to ensure that the model meets expected performance metrics before considering an external release.

The use of the codename "leopard" instead of the previous naming convention used for Claude models may indicate a significant innovation in the model's architecture or capabilities. Leopards are known for their agility and precision, and this naming choice may reflect Anthropic's expectations for the new model's ability to quickly and accurately handle complex problems.

Market competition context

The internal testing information about Claude Opus 4.1 comes at a time when the competition for AI inference capabilities is becoming increasingly intense. OpenAI's GPT-o1 series has shown excellent performance in inference tasks, DeepSeek's R1 model has gained widespread recognition in the open-source community, and Google's Gemini 2.0 continues to optimize its inference capabilities.

In this competitive environment, Anthropic needs to ensure that the Claude series models do not fall behind competitors in terms of inference capabilities. While the Claude model has always been known for its excellent dialogue quality and security, its performance in complex reasoning tasks still has room for improvement compared to some specialized models.

Technology development trends

From an industry trend perspective, large language models are evolving from general conversation toward specialized capabilities. Enhancing reasoning abilities has become a key focus for major manufacturers, not only in traditional reasoning tasks such as mathematics and logic but also extending into professional fields like code generation, scientific research, and complex analysis.

If Claude Opus 4.1 indeed focuses on problem-solving capabilities, it will directly compete with inference-enhanced models in the market. This specialization reflects the important shift in AI technology from "being able to converse" to "being able to think."

Release date speculation

Based on the leak of internal testing screenshots and the use of a "prod" environment, it is likely that Claude Opus 4.1 is close to an official release. Typically, AI companies officially release new models within a few weeks to months after completing internal testing.

Considering the current intensity of competition in the AI industry, Anthropic is likely to officially release this new model soon to respond to challenges posed by other inference-enhanced models in the market.

User expectations and impact

For existing users of Claude, the enhanced reasoning capabilities of Opus 4.1 will significantly improve its practicality in professional work. Whether it's complex analytical tasks, code debugging, or academic research, stronger problem-solving capabilities will make Claude a more valuable AI assistant.

From an industry perspective, the release of Claude Opus 4.1 will further drive the overall improvement of AI inference capabilities and promote continuous innovation and competition among manufacturers in this key technological direction.

Although Anthropic has not officially confirmed this information, the appearance of leaked details usually signals that an official release is imminent. The launch of Claude Opus 4.1 will provide users with a more powerful problem-solving tool and also give Anthropic a new competitive advantage in the fierce AI market.
