Anthropic, an American-based AI startup funded by Amazon, has recently released its most powerful AI models called Claude Opus 4 and Claude Sonet 4, claiming them to be the “world’s best coding models”. Additionally, the company has also announced several new tools for developers.
“Today, we’re introducing the next generation of Claude models: Claude Opus 4 and Claude Sonnet 4, setting new standards for coding, advanced reasoning, and AI agents”, the company stated on its official website. Claude 4 Opus is said to be a significant upgrade on Anthropic’s last model Claude 3.7 Sonet, which was revealed earlier this year.
According to Anthropic, the new models excel in long-running tasks and complex problem-solving. It outperforms other AI Large Language Models (LLM), including Claude 3.7, in SWE-bench, TAU-bench, and Terminal-bench. Both models also offer improved memory retention and critical thinking.

As the race for AI supremacy becomes increasingly complex, Anthropic has adopted a different approach. Rather than developing new chatbots, Atrophic has instead focused on building an AI infrastructure for developers. The company has been training the new models extensively for over a year before releasing them to the market. “We’ve been training these models since last year and really anticipating them. These models are much, much stronger as agents and as coders.”, Jared Kaplan, Anthropic’s chief science officer, said in an interview.
Anthropic has also announced 4 new API capabilities. It has also made Claude Code available for everyone.
Both models are available for Pro, Max, Team, and Enterprise subscribers while Sonet 4 is available for free users as well. Both models can be accessed via Anthropic API, Amazon Bedrock, and Google Cloud’s Vertex AI. Opus 4 will cost $15 and $75 per million input and output tokes respectively. Soet 4 will cost $3 and $15 per million input and output tokens respectively.
