Core Viewpoint - DeepSeek has announced the completion of a minor version upgrade for its R1 model, inviting users to test the new features on its official website, app, and mini-programs while maintaining existing API interfaces and usage methods [1]. Group 1: Upgrade Features - The upgrade focuses on several key areas: 1. Response quality optimization, enhancing accuracy in complex reasoning and multi-step calculations, as well as improving coherence and clarity in long text understanding and generation, and reliability in specialized outputs like mathematics and programming [2]. 2. A slight improvement in response speed, with a 10% to 20% reduction in latency, particularly when processing long text inputs across web, app, and API interfaces [2][4]. 3. Enhanced dialogue stability, with improved context memory, especially in long conversations, supporting up to 128K context and reducing instances of "forgetting settings" or "going off track" [4]. 4. API and interface compatibility remains stable, with no changes to API calling methods, parameters, or return structures, allowing users to seamlessly use the new version without adjustments [5]. Group 2: Upgrade Process - The upgrade is termed a "trial upgrade" due to: 1. It being a "gray release," where a portion of users will experience the upgrade first [6]. 2. The company will collect feedback to ensure stability before a full rollout [6]. 3. Users of the official app, website, or mini-program may already be using the upgraded version in "Deep Thinking" mode [6]. Group 3: Future Developments - There is ongoing speculation regarding the release of the DeepSeek R2 model, with the company previously denying rumors about its launch on March 17 [6].
