What’s New in Anthropic’s Claude 4 Gen AI Models?

Anthropic said it’s using extra safety precautions with its heavy duty Claude 4 Opus model.

The latest versions of Anthropic’s Claude generative AI models made their debut Thursday, including a heavier-duty model built specifically for coding and complex tasks.

Anthropic launched the new Claude 4 Opus and Claude 4 Sonnet models during its Code with Claude developer conference and executives said the new tools mark a significant step forward in terms of reasoning and deep thinking skills.

The company launched the prior model, Claude 3.7 Sonnet, in February. Since then, competing AI developers have also upped their game. OpenAI released GPT-4.1 in April, with an emphasis on an expanded context window, along with the new o3 reasoning model family. Google followed in early May with an updated version of Gemini 2.5 Pro that it said is better at coding.

Claude 4 Opus is a larger, more resource-intensive model built to handle particularly difficult challenges. Anthropic CEO Dario Amodei said test users have seen it quickly handle tasks that might have taken a person several hours to complete.

«In many ways, as we’re often finding with large models, the benchmarks don’t fully do justice to it,» he said during the keynote event.

Claude 4 Sonnet is a leaner model, with improvements built on Anthropic’s Claude 3.7 Sonnet model. The 3.7 model often had problems with overeagerness and sometimes did more than the person asked it to do, Amodei said. While it’s a less resource-intensive model, it still performs well, he said.

«It actually does just as well as Opus on some of the coding benchmarks, but I think it’s leaner and more narrowly focused,» Amodei said.

Anthropic said the models have a new capability, still being beta tested, in which they can use tools like web searches while engaged in extended reasoning. The models can alternate between reasoning and using tools to get better responses to complex queries.

The models offer near-instant response modes and extended thinking modes.

All of the paid plans offer Opus and Sonnet models, while the free plan just has the Sonnet model.

The new models show Anthropic’s focus on building strong coding models, said Arun Chandrasekaran, a distinguished vice president, analyst at Gartner. «Anthropic’s Claude models have established strong leadership in the software engineering domain and the latest Claude 4 release extends that leadership.»

Anthropic triggers safety protocols with new Claude models

In launching the Claude Opus 4 model, Anthropic said it was taking increased safety precautions to reduce the risk of Claude being misused. In a blog post, the company said it hasn’t determined whether the model actually requires the protections of its ASL-3 standard but it is doing so as a precaution.

The safety precautions are specifically designed to prevent Claude from helping with developing chemical, biological, radiological or nuclear weapons. Anthropic said it limited attacks known as universal jailbreaks that let attackers get around existing protocols. «We will continue to evaluate Claude Opus 4’s CBRN capabilities,» Anthropic’s blog post said. «If we conclude that Claude Opus 4 has not surpassed the relevant Capability Threshold, then we may remove or adjust the ASL-3 protections.»

Chandrasekaran said the implementation of safety standards is worth noting. «This includes enhanced cybersecurity measures and prompt classifiers to mitigate risks associated with powerful AI systems,» he said. The new models show the company’s focus on balancing new technology with safety, he said.

‘Is Microsoft Down?’ Outlook and Teams Go Dark in Widespread Outage

It’s not just you: Numerous Microsoft services weren’t working most of Thursday, and the outage is continuing.

Thursday has been a tough work day for many — or maybe, a great one, depending on how eager you are to access work-related programs. Microsoft services, including Outlook, Teams and Microsoft 365 are experiencing a significant outage that’s still going on as of early evening, Pacific time. Microsoft hasn’t announced an expected time when everything will be back up and running.

You can follow the official Microsoft 365 Status account on the social-media platform X, which has been regularly posting updates about the outage.

The first post there, from 11:37 a.m. PT, said that the company was «investigating a potential issue impacting multiple Microsoft 365 services, including Outlook, Microsoft Defender and Microsoft Purview. Further information can be found in the admin center under MO1221364.»

The admin center is the dashboard for IT admins managing Microsoft 365 services.

You can also monitor Microsoft’s Service Health Status page. That page is noting that «users may be seeing degraded service functionality or be unable to access multiple Microsoft 365 services.»

A representative for Microsoft didn’t immediately respond to a request for comment.

Ring’s Latest Feature Lets You Verify Shared Security Videos

With so many fake videos out there, the home-security company is adding a level of protection.

Popular home security brand Ring announced that videos shared from its devices can now be verified, so customers know they’re watching an authentic, unaltered video. Ring says the new verification process is similar to a security seal on a package or medicine bottle, indicating that no one has tampered with it.

The new feature is available starting Thursday, and it doesn’t matter which Ring device recorded the video. All videos downloaded directly from the Ring app are automatically verified and include a security seal for authenticity.

When someone sends you a Ring video, you can now visit Ring’s verification page, paste the video link, and determine immediately whether the video is verified. The website doesn’t send your video anywhere. It stays locally on your device, and all verification checks happen within your browser. The verification website only accepts MP4 files, the format Ring videos are saved.

Videos downloaded before December 2025 or edited videos cannot be verified. Ring says that even minor adjustments, such as shaving a couple of seconds off the beginning or end of a video, or even adjusting brightness levels, will render it unverifiable.
