    This article introduces 'Anamnesis', an AI personality generation tool based on depth psychology. The author points out that current AI character creation often feels artificial due to insufficient context in LLMs when mimicking character speech and thought processes. Anamnesis aims to address this by incorporating deeper psychological profiles. The article is part of the LLM/LLM Utilization Advent Calendar 2025. The core idea is that simply defining superficial traits like speech patterns isn't enough; a more profound understanding of the character's underlying psychology is needed to create truly believable AI personalities. This approach could potentially lead to more engaging and realistic AI characters in various applications.

    AI characters can now be created by anyone, but they often feel "AI-like" simply by specifying speech patterns and personality.

    Analysis

    This article reports on the US government's decision to deny visas to five individuals, including UK-based social media campaigners advocating for tech regulation. The action raises concerns about freedom of speech and the potential for politically motivated visa denials. The article highlights the growing tension between tech companies and regulators, and the increasing scrutiny of social media platforms' impact on society. The denial of visas could be interpreted as an attempt to silence dissenting voices and limit the debate surrounding tech regulation. It also underscores the US government's stance on tech regulation and its willingness to use visa policies to exert influence. The long-term implications of this decision on international collaboration and dialogue regarding tech policy remain to be seen.

    Analysis

    This article reports on Alibaba's upgrade to its Qwen3-TTS speech model, introducing VoiceDesign (VD) and VoiceClone (VC) models. The claim that it significantly surpasses GPT-4o in generation effects is noteworthy and requires further validation. The ability to DIY sound design and pixel-level timbre imitation, including enabling animals to "natively" speak human language, suggests significant advancements in speech synthesis. The potential applications in audiobooks, AI comics, and film dubbing are highlighted, indicating a focus on professional applications. The article emphasizes the naturalness, stability, and efficiency of the generated speech, which are crucial factors for real-world adoption. However, the article lacks technical details about the model's architecture and training data, making it difficult to assess the true extent of the improvements.
