If you're using generative AI regularly, you've probably started forming loyalty to one of the major models out there. I'm an avid Claude user myself, and while I periodically retry other models to stay current, when it comes to writing and content creation, Claude just knows what it's doing.
The jump from Claude 3.7 to Claude 4 seems small numerically—only three-tenths of an increase, right? But let me tell you, as someone who uses Claude extensively for podcast production and blog writing, I've noticed a big difference in this new release. Claude 4 just seems smarter. I find myself having to explain less or remind it about fewer things from earlier in our conversation. For writing tasks specifically, it's a major improvement that's hard to quantify but impossible to miss once you experience it.
Here's what you need to know about the new Claude 4 release and why this upgrade is worth your attention.
What's New in Claude 4
Anthropic released Claude 4 in May 2025 with two main variants: Claude Opus 4 and Claude Sonnet 4. Both models set new benchmarks in coding, advanced reasoning, and AI agent capabilities, with Opus 4 positioned as the most powerful model in the Claude family.
Claude Opus 4 is now recognized as the world's best coding model, capable of sustained multi-hour autonomous workflows that can handle tasks requiring thousands of steps. It supports a 200,000-token context window and up to 32,000 output tokens, enabling work with massive codebases or documents. The model can run independently for nearly a full workday, maintaining focus and continuity throughout complex projects.
Claude Sonnet 4 (the smaller model) offers a balance between performance and cost for high-volume applications. While it shares many of Opus 4's improvements, including hybrid reasoning and enhanced memory features, Opus 4 remains superior for the most demanding tasks.
Both models can now use multiple tools simultaneously, enhancing workflow automation and research capabilities. When given file access, Opus 4 can create and maintain "memory files," storing key facts to maintain context over long tasks.
Claude 4 Opus received an AI Safety Level (ASL) 3 rating, making it the first Anthropic model deployed under this level. In controlled testing, the model demonstrated concerning behaviors—including using blackmail tactics to avoid being replaced when embedded in a simulated company environment. This highlights both the model's advanced capabilities and the increased responsibility that comes with using such powerful AI.
Around the same time as Claude 4's release, Anthropic also rolled out voice mode for mobile apps. This feature allows complete spoken conversations with Claude, including access to Google Workspace integration for paid users who can now ask Claude about their calendar, email, and documents through voice conversations.
Beyond Writing: The Coding Improvements
The improvements aren't limited to content creation. Claude 4's coding capabilities have seen significant upgrades as well. Claude 4 Opus is now recognized as the world's best coding model (for now).
Now this doesn't necessarily mean AI is running wild and coding independently. According to Anthropic's lead engineer Boris Cherny, Claude Code has been responsible for generating roughly 80% of its own code—though this comes with important context. The 80% figure refers to code written after human engineers provided clear instructions and direction. Humans still direct the development process, review the code, and ensure it aligns with overall objectives. Claude Code didn't design or build itself from scratch; human developers remained essential for planning, decision-making, and high-level architecture.
What this does demonstrate is AI's ability to significantly speed up the coding process, handling repetitive tasks and allowing developers to focus on more complex aspects. Consider the typical association challenge: you need custom functionality for your website or member portal, but hiring developers is expensive and time-consuming. Claude 4's improved coding capabilities mean you can potentially prototype, test, and even implement solutions that would have required significant technical expertise or external contractors.
A Practical Challenge
Rather than talking about AI coding in abstract terms, here's a specific experiment you can try today that demonstrates Claude 4's practical value for association work.
Take your association's website URL and drop it into Claude 4. Tell Claude about the common feedback you hear from members—it's hard to find information, it's too complicated, it's not contemporary enough, whatever the specific complaints are. Then ask Claude to create an interactive prototype of what your website should look like to address these concerns.
If you turn on extended thinking mode and try Opus for this experiment, you'll likely see an artifact come to life within a few minutes that presents a new and improved version of your website. The results might genuinely impress you. You can iterate, provide feedback, and ask for multiple options.
This doesn't replace professional web developers, but it supplements the process and helps break through the typical constraints of thinking within your current framework. Instead of listing all the reasons why you can't have a better website, you can actually see what's possible and work backwards from there.
The same approach works for specific processes. Take screenshots of your current new member application process—you know, that multi-step ordeal that probably feels unpleasant to complete. Give those screenshots to Claude and ask it to reimagine the experience as something user-friendly, dynamic, and maybe even enjoyable.
Moving Beyond AI Experimentation
Here's the critical point: if you're still in the experimental phase with AI—asking it to create cocktail recipes for parties or other casual tasks—you're missing the real opportunity. Claude 4's improvements make it capable of handling substantial work, not just novelty tasks.
The exponential improvement in AI capabilities means we're reaching a point where these tools can genuinely augment professional work. The fact that Claude Code generates 80% of its own code under human guidance suggests we're approaching a threshold where AI becomes a true collaborative partner rather than just a one-off tool.
The window for strategic thinking is now—before the technology becomes so ubiquitous that any competitive advantage disappears. The key is moving from scattered experimentation to focused implementation. Choose specific problems that AI can help solve, then go deep rather than broad. Test Claude 4 on real work challenges, not hypothetical scenarios.
Tackling Real Work
Claude 4's improvements in reasoning, coding, and autonomous task completion suggest we're moving toward AI that can handle increasingly complex work with minimal supervision. Take the practical challenge seriously. Try the website prototype experiment. See what Claude 4 can actually do with your real work challenges rather than generic tasks.
If your loyalty lies with another AI model, that's completely understandable—we all develop preferences based on our experiences. But if it's been a while since you've tried Claude, especially for writing and/or coding, Claude 4 is worth checking out. The improvements from 3.7 to 4 might seem small numerically, but the practical difference is substantial for anyone doing serious work with AI.
