Anthropic launches 'Reflect' beta: usage dashboard and AI fluency framework for Claude users
Anthropic introduced a beta 'Reflect' feature for Claude web and desktop users that provides a personal dashboard showing usage patterns, topic breakdowns, and time spent over 1–12 month windows. The feature includes quiet hours, break nudges, and a '4D AI Fluency Framework' (Delegation, Description, Discernment, Diligence) to help users assess and improve how they collaborate with AI. Privacy protections exclude incognito chats, health integration data, and source files from connected tools. The feature was developed in consultation with MIT Media Lab's AHA program, Boston Children's Hospital's Digital Wellness Lab, and the Family Online Safety Institute.

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 launches Projects feature for Claude.ai Pro and Team users
Anthropic introduced Projects for Claude.ai Pro and Team subscribers, allowing users to organize chats with curated knowledge bases, custom instructions, and a 200K context window per project. The feature also includes Artifacts (a side-by-side content generation and preview pane) and team-level conversation sharing via activity feeds. Projects are powered by Claude 3.5 Sonnet and include a privacy commitment that shared data will not be used for model training without explicit consent.
Anthropic launches Claude Science, an AI workbench for scientific research
Anthropic released Claude Science in beta, an AI-powered research environment integrating over 60 curated scientific tools and databases for genomics, proteomics, structural biology, and cheminformatics. The platform features a coordinating agent with specialist sub-agents, a reviewer agent for citation and calculation checking, reproducible auditable artifacts, and flexible compute management across local machines, HPC clusters, and on-demand GPUs. It integrates with NVIDIA's BioNeMo Agent Toolkit, connecting to models like Evo 2, Boltz-2, and OpenFold3. Available to Claude Pro, Max, Team, and Enterprise users, this represents Anthropic's most significant expansion into scientific AI tooling.
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 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 2.1 with 200K context window, reduced hallucinations, and tool use beta
Anthropic released Claude 2.1, featuring an industry-first 200,000-token context window (roughly 500 pages), a claimed 2x reduction in hallucination rates versus Claude 2.0, and a new beta tool-use capability allowing Claude to orchestrate across developer-defined APIs and functions. The release also introduces system prompts and a revamped developer Workbench console. Claude 2.1 is available via API and powers claude.ai for both free and Pro tiers, with the 200K context window reserved for Pro users.
Anthropic launches Claude 2 with 100K context window and improved coding, reasoning, and safety
Anthropic released Claude 2, featuring a 100K token context window, improved performance on coding (71.2% on Codex HumanEval, up from 56.0%), math (88.0% on GSM8k), and legal reasoning (76.5% on the Bar exam multiple choice section). The model is available via API at the same price as Claude 1.3 and through a new public beta at claude.ai for US and UK users. Safety improvements include a 2x reduction in harmful outputs on internal red-team evaluations compared to Claude 1.3. Early API partners include Jasper and Sourcegraph.
Anthropic launches Claude publicly with two model tiers after closed alpha
Anthropic announced the public launch of Claude on March 14, 2023, following a closed alpha with partners including Notion, Quora, and DuckDuckGo. The release introduced two model variants — Claude (high-performance) and Claude Instant (lighter and faster) — accessible via chat interface and API. Early partners reported Claude produced fewer harmful outputs and was more steerable than competing models, with deployments spanning education, legal tech, productivity, and search.
