🚀 Introducing Claude 4: The New Hybrid AI Models
Claude 4 arrives in two flavors: Sonnet 4 and Opus 4. These models are described as hybrid, offering two operational modes – near-instant responses for quick queries and an “extended thinking” mode for complex, long-horizon tasks. This dual-mode approach allows Claude 4 to handle everything from simple answers to deep reasoning and multi-step workflows.
What sets Claude 4 apart is its ability to maintain coherence over extended periods—tasks that can last tens of minutes or even hours—without losing track of context. This is a breakthrough for AI agents, particularly in real-world applications where sustained attention and memory are critical.
Both Sonnet and Opus models support tool use during their thinking phase. While tool integration is becoming table stakes across AI platforms, Anthropic has taken this further by enabling parallel tool usage. This means Claude 4 can query multiple resources simultaneously, significantly improving efficiency and response quality.
Available tools currently include web search, Drive search, Gmail search, and calendar search. The integration is deeply embedded in the MCP (Modular Compositional Prompting) framework—a framework Anthropic pioneered and which has been adopted by OpenAI, Microsoft, Google, and others.
🧠 Extended Thinking and Memory: The Core of Claude 4’s Strength
One of the most talked-about features is Claude 4’s enhanced memory capabilities. Opus 4, in particular, excels at creating and maintaining memory files that hold key information over long sessions, enabling better long-term task awareness and coherence.
Anthropic demonstrated this with examples of companies using Claude 4 for tasks lasting up to seven hours. Imagine an AI assistant that remembers your preferences, understands evolving project contexts, and adapts its responses accordingly—all in real-time. This is what Claude 4 aims to deliver.
To support this, Claude 4 introduces “thinking summaries,” where a smaller model condenses lengthy internal thought processes into concise summaries. This makes interactions smoother and more efficient, though raw chains of thought remain available for advanced users willing to engage with Anthropic’s sales team for specialized access.
💻 Claude 4 as the World’s Best Coding Model
Anthropic boldly claims that Claude 4 Opus is the world’s best coding model. This is no small statement in a market dominated by OpenAI’s Codex and Google’s Gemini models. Claude 4’s edge lies in its agentic capabilities—its ability to use memory, tools, and extended reasoning to complete complex coding tasks reliably.
Claude Code, Anthropic’s coding-specific product built on Claude 4, has also become generally available. It integrates directly into popular IDEs like Visual Studio Code and JetBrains, allowing developers to tag Claude in pull requests and receive in-line code edits, feedback responses, and CI error fixes. This streamlines the development workflow and enhances productivity.
Moreover, Anthropic is releasing a Claude Code SDK, enabling developers to build custom coding agents tailored to their specific needs. This move solidifies Anthropic’s position as a provider of infrastructure and tooling for agentic AI rather than just a chatbot.
📊 Benchmarking Claude 4: A Mixed but Promising Picture
Benchmarks are always a hot topic, and Claude 4’s results are intriguing. According to early evaluations, Claude 4 shows a significant improvement in software engineering benchmarks, notably on SuiteBench Verified tests:
- Claude Sonnet 4 scored 80.2% on SuiteBench Verified with parallel test time compute.
- Claude Opus 4 scored 79.4% on the same benchmark.
- For comparison, OpenAI Codex 1 scored 72%, and Claude Sonnet 3.7 was at 62.3%.
However, the results aren’t uniformly positive. Some benchmarks showed decreases in performance compared to Claude 3.7, which raises questions about consistency. John Shoneth’s analysis highlights that about half the benchmarks submitted by Anthropic showed performance drops. This mixed performance suggests that while Claude 4 is a leap forward in some areas, it may still have rough edges to smooth out.
Additional benchmarks show Claude Opus 4 leading in terminal benchmarks (43.2%) and strong performance in graduate-level reasoning tasks (GPQA Diamond). Multilingual Q&A and high school math competitions also saw improvements.
🔧 New Features in Claude 4 API: Empowering Developers
Anthropic introduced four key new features in the Claude 4 API to enhance developer capabilities:
- Code Execution Tool: Claude 4 can now write and execute Python code on the fly, enabling dynamic problem-solving and automation within prompts.
- MCP Connector: This allows any MCP server to connect to the Claude API, vastly expanding the ecosystem of accessible tools.
- Files API: Developers can grant Claude access to local files, particularly code repositories, making it easier to work with project-specific data.
- Prompt Caching: To optimize cost and efficiency, prompt caching stores inputs for up to one hour, reducing redundant processing.
These features underscore Anthropic’s focus on building an infrastructure layer for AI agents that can be deeply integrated into complex workflows.
🏆 The Strategic Pivot: From Chatbots to Agentic Infrastructure
Perhaps the most important takeaway from Claude 4’s launch is Anthropic’s strategic shift. According to Jared Kaplan, Anthropic’s Chief Science Officer, the company has stopped investing in chatbots as of late 2024. Instead, they are focusing on complex task completion and agentic AI capabilities.
This pivot makes sense in today’s competitive AI landscape. OpenAI, Google, and Microsoft dominate the chatbot and personal assistant space, making it difficult for newcomers to gain significant mindshare. Anthropic’s decision to focus on infrastructure and tooling for intelligent agents positions them uniquely as a foundational player rather than a consumer-facing chatbot provider.
By providing the best coding agents and supporting tools, Anthropic aims to become the backbone for AI-driven workflows across industries, from software development to enterprise document management.
🔗 Integration with Industry Leaders: GitHub, Box AI, and More
Claude 4’s impact is already visible in major industry partnerships. GitHub’s CEO Thomas Domke announced that Claude 4 is now the default option powering GitHub Copilot, a leading AI coding assistant. This collaboration signals strong confidence in Claude 4’s coding prowess and agentic capabilities.
Another exciting partnership is with Box AI, the sponsor of Matthew Berman’s video. Box AI leverages Claude 4’s strengths to extract metadata from contracts, invoices, resumes, and more, while automating workflows with enterprise-grade security and compliance. Developers can build on Box AI easily, with Box handling the entire retrieval-augmented generation (RAG) pipeline, removing the complexity of vector databases and chunking.
With the launch of Cloud Code, integrating Claude 4 with Box SDKs is intuitive—just provide links to the Box developer docs, and Cloud Code takes care of the rest. This synergy between Claude 4 and Box AI highlights how agentic AI is transforming enterprise document and data workflows.
💰 Claude 4 Pricing: What to Expect
Claude 4 Opus is positioned as the most intelligent model for complex tasks, featuring a 200,000-token context window, which is relatively modest compared to some competitors but still substantial for many applications.
Pricing details are as follows:
- Input tokens: $15 per million tokens
- Output tokens: $75 per million tokens
- Batch processing: 50% discount
This pricing structure encourages efficient usage and offers cost savings for users processing large volumes of tokens via batch operations.
