Anthropic Study: Affective Conversations Comprise 2.9% of Claude.ai Usage
Anthropic published a large-scale analysis of how users engage with Claude for emotional support, advice, and companionship, drawing on 131,484 affective conversations identified from ~4.5 million Claude.ai Free and Pro interactions. Key findings: only 2.9% of conversations are affective in nature, companionship and roleplay combined account for under 0.5%, and user sentiment generally becomes more positive over the course of coaching and counseling exchanges. The study used Anthropic's privacy-preserving Clio analysis tool and aligns with similar low-rate findings from OpenAI and MIT Media Lab research on ChatGPT. Anthropic frames this as part of its safety mission to understand and mitigate potential harms from AI emotional engagement, including unhealthy attachment and emotional exploitation.

Anthropic publishes large-scale study of how university students use Claude
Anthropic analyzed one million anonymized student conversations on Claude.ai to produce one of the first large-scale empirical studies of real-world AI usage in higher education. Key findings: Computer Science students are heavily overrepresented (36.8% of conversations vs. 5.4% of U.S. degrees), while Business, Health, and Humanities students underuse the tool relative to enrollment. Students primarily engage in higher-order cognitive tasks per Bloom's Taxonomy—creating and analyzing—though the study raises concerns about offloading critical thinking. The analysis used Anthropic's internal Clio tool, which aggregates conversation patterns while stripping personal information.
Anthropic Education Report: How Educators Use Claude in Higher Education
Anthropic analyzed ~74,000 anonymized conversations from higher education professionals on Claude.ai during May–June 2025, finding that curriculum development dominates educator AI use (57% of conversations), followed by academic research (13%) and student assessment (7%). Faculty are not only using Claude as a chatbot but also building custom interactive tools via Claude Artifacts, such as chemistry simulations and grading rubrics. The study, complemented by qualitative research with 22 Northeastern University faculty, reveals a spectrum from augmentation (lesson design, advising) to automation (routine administrative tasks), with grading being a contested and relatively rare but automation-heavy use case.
Anthropic Economic Index: Second Report on Claude 3.7 Sonnet Usage Patterns and Labor Market Effects
Anthropic has released its second Anthropic Economic Index report, analyzing 1 million anonymized Claude.ai conversations following the launch of Claude 3.7 Sonnet. Key findings include a rise in coding, education, science, and healthcare usage shares; extended thinking mode is predominantly used for technical tasks (computer science researchers ~10%, software developers ~8%); and augmentation still comprises 57% of usage versus automation. The report also introduces a novel bottom-up taxonomy of 630 granular usage categories and releases task-level datasets publicly on Hugging Face.
Anthropic Details Safeguards for User Wellbeing: Crisis Detection, Anti-Sycophancy, and Evaluation Results
Anthropic has published a detailed account of its user wellbeing safeguards, covering how Claude handles suicide and self-harm conversations through model training, system prompts, and a real-time crisis classifier integrated with ThroughLine's global helpline network. The post discloses evaluation results for Claude Opus 4.5, Sonnet 4.5, and Haiku 4.5, showing 98–99% appropriate response rates on high-risk single-turn prompts and very low false-refusal rates on benign requests. Anthropic also addresses anti-sycophancy efforts and an 18+ age requirement for Claude.ai. The company is partnering with the International Association for Suicide Prevention (IASP) to further inform training and product design.
Anthropic Launches Economic Index: First Large-Scale Empirical Study of AI's Labor Market Impact
Anthropic has released the Anthropic Economic Index, an initiative tracking AI's effects on labor markets using anonymized data from approximately one million Claude.ai conversations matched to U.S. Department of Labor O*NET occupational tasks. Key findings show AI use is concentrated in software development and technical writing, with 36% of occupations seeing AI use in at least 25% of their tasks, and usage skewing toward augmentation (57%) over automation (43%). The underlying dataset is being open-sourced to enable independent research, and Anthropic is inviting economists and policy experts to contribute to the ongoing initiative. The analysis was enabled by Clio, Anthropic's privacy-preserving internal conversation analysis tool.
Anthropic Commits Claude to Remaining Ad-Free, Citing Alignment and User Trust
Anthropic has published a policy statement declaring that Claude will not carry advertising, sponsored content, or third-party product placements in conversations. The company argues that ad-based incentives are structurally incompatible with Claude's constitution and the goal of acting unambiguously in users' interests, citing the sensitive and personal nature of many AI conversations. Anthropic's revenue model relies on enterprise contracts and paid subscriptions, and the post signals openness to agentic commerce features where Claude acts on a user's behalf rather than on behalf of advertisers. The company acknowledges other AI companies may reach different conclusions and commits to transparency if this policy changes.
Early methods for studying affective use and emotional well-being on ChatGPT
OpenAI and MIT Media Lab have published a collaborative research study examining how users engage with ChatGPT in emotionally significant ways and the implications for user well-being. The work represents an early methodological effort to measure and understand affective use patterns on large-scale conversational AI systems. This falls within OpenAI's broader safety and responsible deployment research agenda.
Anthropic Launches Multi-Tradition Dialogue Program on AI Moral Formation
Anthropic has begun a structured outreach program engaging scholars, clergy, philosophers, and ethicists from over 15 religious and cross-cultural traditions to inform Claude's character development and values training. The initiative is framed as a research workstream on 'moral formation' of AI systems, directly feeding into Claude's constitution and alignment evaluations. A concrete experiment emerged from these dialogues: giving Claude a mid-task tool that surfaces its own ethical commitments, which showed measurably lower rates of misaligned behavior on internal evaluations. Anthropic plans to expand engagement to legal scholars, psychologists, and civic institutions, with future discussions addressing AI's impact on work, institutions, and power distribution.
