Anthropic today announced the launch of its latest AI model, Claude Opus 4.8. Anthropic claims the model is a "more effective collaborator" with improvements in agentic coding, multidisciplinary reasoning, agentic computer use, knowledge work, and agentic financial analysis. Testers have found Opus 4.8 to be "more reliable and sharper in its judgement" when doing agentic tasks, and the model also made gains in honesty. Early testers report that Opus 4.8 is more likely to flag uncertainties about its work and less likely to make unsupported claims. This is borne out in our evaluations, which show that Opus 4.8 is around four times less likely than its predecessor to allow flaws in code it has written to pass unremarked. Alignment assessments suggest the model hits new highs on measures of prosocial traits like supporting user autonomy and acting in the user's best interest. Rates of misaligned behavior like deception are lower than Opus 4.7 and similar to the Claude Mythos Preview. Anthropic benchmarks indicate Opus 4.8 scored a 69.2% on SWE-Bench Pro, outperforming GPT–5.5 and Gemini 3.1 Pro on the test and several other benchmarks, though GPT–5.5 leads on the terminal-coding benchmark. Opus 4.8's fast mode also runs at 2.5x the speed, and it is now three times cheaper than prior models. Along with Opus 4.8, Anthropic is adding new features to its product lineup. Dynamic workflows (research preview) - Claude can complete bigger tasks in Claude Code. It is able to plan work and run hundreds of parallel subagents in a single session. It is able to complete codebase-scale migrations across hundreds of thousands of lines of code. The feature is available for Claude Code for Enterprise, Team, and Max plans. Effort control - In Claude.ai and Cowork, users can choose how much effort Claude puts into a response. With a lower setting, Claude will respond faster and use up rate limits more slowly. Opus 4.8 defaults to high effort, which Anthropic says is the best balance of quality and user experience. Messages API - The Messages API accepts system entries inside the messages array, so developers can update Claude's instructions mid-task. Claude Opus 4.8 is available everywhere today. Pricing for regular use has not changed compared to Opus 4.7. Anthropic is working on models that have the same capabilities as Opus 4.8 at a lower cost, and a new class of model that's even more intelligent than Opus. Anthropic says it has been developing safeguards for the Claude Mythos model it is testing with a small number of organizations, and it expects to be able to bring Mythos-class models to all customers "in the coming weeks."

Oura today unveiled the Oura Ring 5 , a significantly smaller smart ring with new health-monitoring capabilities including blood pressure trend detection, nighttime breathing analysis, and tools for GLP-1 medication tracking. The Oura Ring 5 is 40% smaller than its predecessor, measuring 6.09mm wide and 2.29mm thick compared to 7.99mm and 2.88mm on the previous model. Oura says the reduction was achieved by redesigning the mechanical, electrical, optical, battery, and sensing architectures, and the company claims the new form factor more closely resembles a traditional wedding band. Despite the smaller size, Oura says battery life remains at approximately one week per charge. The ring's sensing system has also been overhauled. A new signal architecture uses precision-engineered sensor domes for better skin contact, more powerful LEDs, and twelve signal pathways that Oura says deliver greater accuracy across more finger types and skin tones. The headline software addition is "Health Radar," a proactive health-monitoring feature that builds on the company's existing Symptom Radar tool, which launched in 2024 to flag early signs of illness. Health Radar includes two initial capabilities: Blood Pressure Signals and Nighttime Breathing. Blood Pressure Signals continuously monitors for patterns that may indicate cardiovascular strain, surfacing nighttime blood pressure trends. Nighttime Breathing provides a 30-day rolling view of sleep-related breathing disturbances, with guidance on when to seek further evaluation. A new Health Records feature allows U.S. users to import diagnosed conditions, medications, lab results, and allergies directly into the app. Oura has also partnered with Counsel Health, an AI-powered virtual care platform, to let eligible users in 43 U.S. states ask health questions and connect with licensed physicians from within the app for an additional fee. New GLP-1 Insights tools let users track medication dosing, side effects, weight changes, and biometric data in one place. A Lab Uploads feature lets users import blood biomarker results alongside Oura's biometric data. Other new features include live workout tracking with real-time pace, distance, and heart rate via a connected device, a Brain Health Study through Oura Labs pairing cognitive assessments with biometric data, and a time-based Data Deletion tool allowing users to erase data from specific periods without affecting their full history. An optional new Charging Case accessory provides one month of battery and supports wireless charging, priced at $99. Oura is also introducing a Locate feature to track misplaced rings and charging cases. The Oura Ring 5 is priced at $399 in Silver and Black, with Gold, Stealth, Brushed Silver, and Deep Rose finishes priced at $499. The Oura Ring 4 in ceramic remains available at $349. An Oura Membership is required for full functionality at $5.99 per month or $69.99 annually. Global pre-orders open today , with shipping beginning June 4.
