Anthropic has just released its latest Large Language Model (LLM), Claude Sonnett 4.6. The Tuesday release quickly follows the launch of Claude Opus 4.6, the company’s premium AI model, on Feb. 5.

According to Anthropic, “Claude Sonnet 4.6 is our most capable Sonnet model yet.” The company says Sonnet 4.6 has a 1 million token context window in beta. Crucially, Anthropic reports that Sonnet 4.6 performed well on internal safety tests, showing a low tendency to hallucinate and engage in sycophancy. 

“Sonnet 4.6 brings much-improved coding skills to more of our users,” Anthropic said, referring to Claude’s popularity among developers who use AI to code.

If you’re looking to use Anthropic’s latest AI model, the company has made it really easy. Here’s how to access Clause Sonnet 4.6.

How to use Claude Sonnet 4.6

For both free and Pro users, Claude Sonnett 4.6 is available now as the default model on claude.ai and Claude Cowork. Anthropic has also rolled the model out through its API and all major cloud platforms.

Free users will have limited usage rates that depend on current demand. Limits reset every five hours. For those who need higher limits, Claude Sonnet 4.6 costs the same price rate as the previous model. The Claude Pro plan costs $20 per month or $17 per month if paid annual. If going through the API, Claude Sonnett 4.6 starts at $3 per million input tokens and $15 per million output tokens.

Claude Sonnet 4.6 benchmark performance

According to Anthropic’s benchmark tests, Claude Sonnet 4.6 is the company’s most powerful model for agentic financial analysis and office tasks, beating out competitors like Google’s Gemini 3 Pro and OpenAI’s GPT 5.2. 

On those tasks, Claude Sonnet 4.6 also beats out Anthropic’s own Opus 4.6, Anthropic’s most powerful AI model. 

In its release announcement, Anthropic said that many developers with early access to Claude Sonnet 4.6 preferred the model — not just to its predecessor, Claude Sonnet 4.5, but also Claude Opus 4.5. According to the Sonnet 4.6 system card, the new model improves on key benchmarks like Humanity’s Last Exam, though Claude Opus 4.6 scored higher.

Benchmark performance

• GPQA Diamond: 89.9 percent

• ARC-AGI-2: 58.3 percent

• MMMLU: 89.3 percent

• SWE-bench Verified: 79.6 percent

• HLE (Humanity’s Last Exam): With tools 49.0 percent, without tools 33.2 percent

AI-powered insurance company Pace told VentureBeat that Sonnet 4.6 scored the best out of any Claude model on its complex insurance computer use benchmark.

These results are notable as Claude Opus models are generally the more intelligent and preferable for complex reasoning.

Claude Sonnet 4.6 is not only more powerful than some Opus models, but more affordable too. As previously mentioned, Claude Sonnet 4.6 is priced at $3/$15, whereas Opus 4.6’s rates are $5/$25.

If you can’t watch YouTube videos right now, you’re not alone. A Tuesday evening YouTube outage affected users across the globe, with problems starting around 8:00 p.m. ET. Early reports are sketchy, but here’s what we know.

The NYT Connections puzzle today is not too difficult to solve if you keep up with the latest styles.

Connections is the one of the most popular New York Times word games that’s captured the public’s attention. The game is all about finding the “common threads between words.” And just like Wordle, Connections resets after midnight and each new set of words gets trickier and trickier—so we’ve served up some hints and tips to get you over the hurdle.

If you just want to be told today’s puzzle, you can jump to the end of this article for today’s Connections solution. But if you’d rather solve it yourself, keep reading for some clues, tips, and strategies to assist you.

What is Connections?

The NYT‘s latest daily word game has become a social media hit. The Times credits associate puzzle editor Wyna Liu with helping to create the new word game and bringing it to the publications’ Games section. Connections can be played on both web browsers and mobile devices and require players to group four words that share something in common.

Each puzzle features 16 words and each grouping of words is split into four categories. These sets could comprise of anything from book titles, software, country names, etc. Even though multiple words will seem like they fit together, there’s only one correct answer.

If a player gets all four words in a set correct, those words are removed from the board. Guess wrong and it counts as a mistake—players get up to four mistakes until the game ends.
