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 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 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 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 launches Claude for Education with Learning Mode and university partnerships
Anthropic announced Claude for Education, a specialized offering for higher education institutions featuring a new 'Learning mode' that uses Socratic questioning to guide student reasoning rather than providing direct answers. The launch includes campus-wide access agreements with Northeastern University, London School of Economics, and Champlain College, covering 50,000+ students and staff. Anthropic is also joining Internet2, partnering with Instructure to embed Claude in Canvas LMS, and launching student ambassador and API credit programs. The initiative positions Anthropic as a major player in the edtech AI market while introducing a pedagogically-motivated model behavior mode.
How scientists are using Claude to accelerate research and discovery
Anthropic describes how researchers are deploying Claude-powered systems across scientific workflows, highlighting three case studies: Biomni (a Stanford agentic platform integrating hundreds of biomedical tools), the Cheeseman Lab (automating large-scale gene knockout experiment interpretation), and others. The piece details Claude for Life Sciences and the AI for Science program, which provides free API credits to high-impact research projects. Specific benchmarks cited include compressing months-long GWAS analyses to 20 minutes and analyzing 336,000 single-cell datasets to identify novel transcription factors.
Anthropic introduces computer use capability, upgraded Claude 3.5 Sonnet, and Claude 3.5 Haiku
Anthropic announced three major developments: an upgraded Claude 3.5 Sonnet with significant coding improvements (SWE-bench Verified rising from 33.4% to 49.0%, surpassing all publicly available models including reasoning models), a new Claude 3.5 Haiku that matches Claude 3 Opus performance at Haiku-tier speed, and a public beta of 'computer use' — a capability allowing Claude to control computers by viewing screens, moving cursors, clicking, and typing. Computer use is available via the Anthropic API, Amazon Bedrock, and Google Cloud Vertex AI, with early adopters including Replit, The Browser Company, and Cognition. Both safety institutes (US AISI and UK AISI) conducted pre-deployment testing, and the model was assessed as remaining within ASL-2 under Anthropic's Responsible Scaling Policy.
Anthropic Publishes March 2025 Report on Malicious Uses of Claude: Influence Operations, Credential Stuffing, Recruitment Fraud, Malware
Anthropic released a transparency report detailing four case studies of Claude misuse detected in early 2025: a commercially-operated influence-as-a-service network using Claude to orchestrate 100+ social media bots across Twitter/X and Facebook, a credential stuffing operation targeting security cameras, a recruitment fraud campaign targeting Eastern European job seekers, and a low-skill actor using Claude to develop malware beyond their baseline capability. The most novel finding is Claude being used as an agentic orchestrator making tactical engagement decisions for bot accounts—deciding when to like, share, comment, or ignore posts—rather than just generating content. Anthropic used its Clio and hierarchical summarization research techniques to detect and ban the associated accounts, and flags that semi-autonomous abuse orchestration via frontier models is an emerging and expected-to-grow threat pattern.
