Meanwhile, Anthropic’s approach is coming at a time of breakneck progress in artificial intelligence, particularly when it comes to generative AI. With Claude, organizations can be more confident in the quality of their outputs, Rehl said, giving Anthropic a “really interesting niche” that no other company can really fill. Perhaps the biggest difference between Claude and ChatGPT is that the former is generally considered to be better at producing consistently safe responses. “They’re only deploying the large language model and nothing is going back into their algorithms.” When it comes to Anthropic and data, “it is a one way street,” Ashok Shenoy, a VP of portfolio development at tech company and Claude user Ricoh USA, told Built In. In many ways, Claude is very similar to ChatGPT, which is hardly surprising given that all seven of Anthropic’s co-founders worked at OpenAI before starting their own company in 2021.

• In March 2025, Anthropic added a web search feature to Claude, starting with paying users in the United States.
• It scored highly in most benchmarking tests, and according to Anthropic, is one of the safest models available, not falling for as many tricks as its competitors.
• “Claude Opus 4.7 is more reliably honest than Opus 4.6 or Sonnet 4.6, with large reductions in the rate of important omissions, and moderate improvements in factuality and rates of hallucinated input,” the model card states.

Do I need both apps to use Cowork?

In June 2024, Anthropic released the Artifacts feature, allowing users to generate and interact with code snippets and documents. Claude is a series of large language models developed by Anthropic and first released in 2023. Our latest Opus model brings stronger performance across coding, agents, vision, and multi-step tasks, with greater thoroughness and consistency on the work that matters most. You can preview running servers, review local code changes, and monitor pull request status without leaving the app. The desktop app needs to be running for Claude to complete tasks. Connectors allow Claude to work with tools like your apps and databases.

A new update to Claude’s desktop app and web platform adds document creation capabilities to the chatbot. Sonnet 4.5 keeps the same pricing of $3 per million input tokens and $15 per million output tokens, and is available through the Claude API and Chatbot, as well as in coding applications like Cursor and Windsurf. According to the company, Sonnet 4.5 can build production-ready applications by creating more than just user interfaces and simple logic. The model includes improvements to its context window and input processing, and it scored higher than both Haiku and Sonnet 4.5 on the SWE-Bench Verified software assessment. Claude Code has become a central tool in the vibe coding movement, a trend where plain language instructions and project “vibes” replace traditional manual programming. Users can also dictate specific tasks through Claude’s chatbot interface instead of a device’s terminal or integrated development environment.

But the model’s cyber capabilities are not as advanced as Claude Mythos Preview, which Anthropic rolled out to a select group of companies as part of a new cybersecurity 4rabet app login initiative called Project Glasswing earlier this month. Claude Opus 4.7 is better at software engineering, following instructions, completing real-world work and is its most powerful generally available model, Anthropic said. But it is a responsible, transparent AI that you can try for free at Claude.ai — no login required for limited free access.

Pair the desktop and mobile apps. Pair with the desktop app. Works with your files and apps to get things done. All of Claude, in one app. Anthropic rolled out computer use functionality for Claude in October 2024, allowing developers to employ Claude to perform tasks on a computer in the same way a human user would — by clicking, typing, copying and pasting. And Claude’s outputs are normally more helpful and less harmful than those of other chatbots because it was trained using constitutional AI.

The team watched the model build an application, stand up database services, purchase domain names, and perform a SOC 2 audit. One of the big claims that Anthropic has made about this latest version of the tool is that it is able to autonomously code for up to 30 hours. This demonstrates a noticable jump in performance, where most other AI chatbots that are producing code keep to simple developments.

Positioned as the company’s most intelligent system, it emphasizes careful planning, sustained problem solving and reliability in real-world tasks rather than quick conversational responses. Claude Opus 4.6 is Anthropic’s flagship frontier model, designed for complex reasoning, long-context analysis and agent-level workflows. In fact, these days, Anthropic seems to be just as much a research company as it is the provider of a chatbot tool. Anthropic committed to preserve the weights of the retired models “for at least as long as the company exists”; the company also conducts “exit interviews” with models before their retirement.

We’re excited about the potential applications Claude can power across industries. We are proud to partner with AssemblyAI, an innovative AI company that is partnering with Anthropic to help power its platform of APIs that transcribe and understand audio data at scale. Notion users can now work more efficiently and improve their writing skills, all within the Notion workspace.” Vivian Shen, CEO of Juni Learning, says, “We evaluated Anthropic against competitors, and for our use case and implementation we chose to incorporate Claude based on its helpful, high-quality responses.

Claude Opus 4.7: Benchmark performance

This technique is similar to RLHF, except that the comparisons used to train the preference model are AI-generated. Claude is then fine-tuned to align with this preference model. For the reinforcement learning from AI feedback (RLAIF) phase, responses are generated, and an AI compares their compliance with the constitution. Time described this constitution as “somewhere between a moral philosophy thesis and a company culture blog post”. Anthropic said it intends Claude’s constitution to be a model followed by others in the industry. Anthropic introduced an approach to AI alignment called “Constitutional AI”.

Alongside the release, Anthropic expanded access to its Claude for Chrome and Claude for Excel extensions, which use Claude Opus 4.5 to automate workflows in internet browsers and Microsoft Excel. Through Cowork, users can designate specific folders, allowing Claude to read and modify files. Code Review is available as a research preview in beta for Claude Team and Enterprise plan users. When a pull request is opened, Code Review uses a multi-agent team to look for coding bugs in parallel, verify bugs to filter out false positives and rank bugs by severity, and displays the result as comments on the pull request. The new tool can generate pitch decks, product mockups, wireframes and user interfaces through natural language instructions.
