Introducing Claude Sonnet 5 Anthropic has launched Claude Sonnet 5, the latest iteration of its agentic AI model series, designed to deliver advanced capabilities in planning, tool integration, and autonomous execution at a lower cost than previous models. This release marks a significant step forward in the agentic AI era, bridging the gap between Sonnet-class and Opus-class models while offering competitive pricing and improved performance. Sonnet 5 is positioned as a substantial upgrade over its predecessor, Sonnet 4.6, with notable improvements in reasoning, tool use, coding, and knowledge work. Performance evaluations show it closely rivals Opus 4.8, a more broadly capable model, but at a significantly lower cost. The model’s agentic capabilities are highlighted through comparisons with earlier versions, demonstrating its ability to handle complex tasks such as multi-step software engineering workflows, cybersecurity assessments, and automated workflows with greater efficiency. Pricing for Sonnet 5 is structured to make it accessible across all user tiers. It is the default model for Free and Pro plans and is available to Max, Team, and Enterprise users. During its introductory launch period through August 31, 2026, Sonnet 5 is priced at $2 per million input tokens and $10 per million output tokens, after which the rates will increase to $3 per million input tokens and $15 per million output tokens. Developers can access the model via the Claude API using the identifier claude-sonnet-5. The model’s performance is benchmarked against Sonnet 4.6 and Opus 4.8 in evaluations such as agentic search (BrowseComp) and computer use (OSWorld-Verified). Sonnet 5 is described as a strict improvement over Sonnet 4.6, offering a balance of cost and performance that makes it a compelling alternative to Opus 4.#anthropic #mythos_preview #claude_sonnet_5 #sonnet_4_6 #opus_4_8
Claude AI Faces Global Outage After Anthropic’s Mythos Preview Reveal Services powered by Anthropic’s Claude AI experienced a widespread disruption on Tuesday, leaving users across regions unable to access key tools including Claude Chat, Claude Code, and the mobile application. The outage surfaced shortly after the company unveiled its latest artificial intelligence model, Claude Mythos Preview, sparking speculation about a possible connection between the announcement and the service instability. According to outage-tracking platform Downdetector, reports of issues began rising rapidly, with the disruption peaking at approximately 12:30 PM IST in India. At that point, nearly 491 users had flagged problems with accessing Claude’s services. Anthropic officially acknowledged the outage earlier at 06:23 UTC (11:53 AM IST), stating that it was investigating the issue. In a subsequent update at 07:59 UTC (1:29 PM IST), the company confirmed that the root cause had been identified and that a fix was actively being rolled out. The timing of the outage drew attention as it came just hours after Anthropic introduced Claude Mythos Preview, its most advanced AI model to date. The company claims the new model surpasses its previous flagship, Claude Opus 4.6, as well as competing systems like Gemini 3.1 across multiple performance benchmarks. Highlighting its potential, Anthropic revealed that Mythos was capable of identifying thousands of cybersecurity vulnerabilities across applications and operating systems—many of which had reportedly gone undetected by human reviewers. To further strengthen its rollout, Anthropic noted that it is collaborating with over 40 technology companies to test Mythos and address identified vulnerabilities before a broader public release.#anthropic #claude_ai #claude_code #claude_chat #mythos_preview
