Anthropic, a startup backed by Google and Amazon, has introduced a new AI model named Claude 3.5 Sonnet alongside a revamped user interface to enhance productivity. The release comes just three months after the launch of its Claude 3 family of AI models. Claude 3.5 Sonnet surpasses its predecessor, Claude 3 Opus, in benchmark exam performance, speed, and cost efficiency, being five times cheaper for developers.

CEO Dario Amodei emphasised AI's flexibility and rapid advancement, noting that, unlike physical products, AI models can be quickly updated and improved. Anthropic's latest technology is now available for free on Claude.ai and through an iOS app. Additionally, users can opt into a new feature called 'Artifacts,' which organises generated content in a side window, facilitating collaborative work and the production of finished products.

Anthropic's rapid development cycle reflects the competitive nature of the AI industry, with companies like OpenAI and Google also pushing forward with significant AI advancements. The startup plans to release more models, including Claude 3.5 Opus, within the year while focusing on safety and usability.
