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 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.
Claude 3.7 Sonnet and Claude Code: Anthropic's First Hybrid Reasoning Model and Agentic Coding Tool
Anthropic has released Claude 3.7 Sonnet, described as their most capable model to date and the first hybrid reasoning model on the market, capable of operating in both standard and extended thinking modes within a single unified model. The model achieves state-of-the-art results on SWE-bench Verified and TAU-bench, with particular strength in coding and front-end web development. Alongside the model, Anthropic is launching Claude Code in limited research preview, a command-line agentic coding tool that can read/edit files, run tests, and push to GitHub. Pricing remains unchanged at $3/M input and $15/M output tokens, with availability across Claude.ai plans, Amazon Bedrock, and Google Cloud Vertex AI.
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 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 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 Releases Claude Sonnet 4.6 with 1M Token Context, Improved Computer Use, and Coding Capabilities
Anthropic has released Claude Sonnet 4.6, positioned as a major upgrade over Sonnet 4.5 with improvements across coding, computer use, long-context reasoning, and agent planning. The model features a 1M token context window in beta and is now the default on claude.ai Free and Pro plans at unchanged pricing ($3/$15 per million tokens). Notably, users preferred Sonnet 4.6 over the prior Opus 4.5 frontier model 59% of the time in coding tasks, and the model shows significant gains on OSWorld computer-use benchmarks alongside improved prompt injection resistance. Safety evaluations found no major alignment concerns and rated it as safe or safer than prior Claude models.
Introducing Claude 3.5 Sonnet
Anthropic launches Claude 3.5 Sonnet, the first model in its Claude 3.5 family, claiming it outperforms Claude 3 Opus and competitor models on GPQA, MMLU, and HumanEval benchmarks while operating at twice the speed and mid-tier pricing ($3/$15 per million tokens). The model features a 200K context window, improved vision capabilities, and an internal agentic coding evaluation score of 64% versus 38% for Opus. Alongside the model, Anthropic introduces Artifacts on Claude.ai, a dedicated workspace for real-time editing of AI-generated content. The model was pre-deployment evaluated by the UK AI Safety Institute and assessed at ASL-2.
