Leaked "Soul Doc" reveals how Anthropic programs Claude’s character

Mistral AI has launched the Mistral 3 family, a suite of 10 open-source models designed for diverse applications, including smartphones, drones, and enterprise systems. This release represents a significant advancement in Mistral's efforts to compete with major tech players like OpenAI and Google, as well as emerging competitors from China.

A user of Claude has successfully utilized the Claude 4.5 Opus model to generate a comprehensive 14,000-token document, referred to as its 'Soul overview.' This document is believed to have been instrumental in shaping the model's personality during its training phase, as confirmed by an Anthropic staff member.

Jared Kaplan, chief scientist at Anthropic, has highlighted a critical decision facing humanity by 2030 regarding the autonomy of artificial intelligence systems, which could lead to an 'intelligence explosion' or a loss of human control. This pivotal moment raises questions about the extent to which AI should be allowed to train itself and evolve independently.

Nvidia showcased new AI models for autonomous driving and speech processing at the NeurIPS conference, highlighting its commitment to advancing artificial intelligence technologies. This presentation underscores Nvidia's role as a leader in AI innovation, particularly in sectors that require sophisticated machine learning capabilities.

OpenAI is set to launch a new reasoning model next week, which internal tests suggest will outperform Google's Gemini 3. This release indicates a strategic shift within OpenAI, prioritizing this model over other ongoing projects.

A recent study utilizing the SCONE-bench benchmark of 405 smart contracts revealed that AI models Claude Opus 4.5, Sonnet 4.5, and GPT-5 collectively identified and developed exploits valued at $4.6 million. This highlights the growing capabilities of AI in cybersecurity tasks, showcasing their potential economic impact.

Apple's head of AI, John Giannandrea, has announced his resignation, effective spring 2026, amid ongoing challenges with the Siri voice assistant. This departure marks a significant shift in leadership for the company's artificial intelligence division, which has faced scrutiny over its performance and capabilities.

A recent study has applied Singular Learning Theory (SLT), a physics-inspired framework, to explore the complexities of modern neural networks, particularly focusing on phenomena like grokking and phase transitions. The research empirically investigates SLT's free energy and local learning coefficients using various neural network models, aiming to bridge the gap between theoretical understanding and practical application in machine learning.
