Claude Opus 4.5: AI Coding Revolution Arrives
Claude Opus 4.5 dropped, and Anthropic’s grip on AI-assisted coding tightened. That momentum isn’t confined to one company. Take Cursor: the platform, which stitches together models from Anthropic and others, hit $1 billion in annualized recurring revenue back in November.
A source close to the outfit says December’s month-over-month revenue growth was especially sharp. The race is on. OpenAI, Google, and xAI are all scrambling to deploy their own models in competing agentic coding tools.
Not content to stay in the terminal, Anthropic launched Cowork earlier this month—an AI agent built to manage files and interact with software directly, no command line required. Boris Cherny, who worked on Claude Code, remembers the uncertainty a year ago. "We weren't sure if agentic coding was even going to be a thing," he said.
"I wrote maybe 5 percent of my code with it."
While Anthropic feels dominant in AI coding, the buzz around Claude Opus 4.5 appears to be lifting several companies. Cursor, which lets users code using models from Anthropic and other AI labs, also said its coding tool reached $1 billion in ARR in November. In December, the company posted particularly strong month-over-month revenue growth, according to a person close to the company.
OpenAI, Google, and xAI are also racing to claim a larger share of the AI coding market, developing agentic products of their own powered by in-house AI models. Now, Anthropic is trying to use Claude Code's momentum to create agents for non-coding sectors. Earlier this month, the company launched Cowork, an AI agent that can manage files on a user's computer and interact with software--without requiring any interaction with a coding terminal.
This interview has been edited and condensed for clarity. WIRED: There's been excitement around Claude Code for months. BORIS CHERNY: We released Claude Code like a year ago, and at the time, we weren't sure if agentic coding was even going to be a thing.
We had this hypothesis that maybe the model is ready for something like this. When we first launched this, I wrote maybe 5 percent of my code with Claude Code.
With Cowork, Anthropic jumps the fence out of developers’ terminals and into the general user’s workspace. The bet is clear: if Claude’s models can write code effectively, they can probably manage your computer tasks too. For now, that move gives them an edge—but not much breathing room. OpenAI, Google, and xAI are already deep in the same sector.

Common Questions Answered
How does Claude Opus 4.5 compare to previous versions in terms of coding performance?
[vertu.com](https://vertu.com/lifestyle/claude-opus-4-5-vs-gpt-5-2-codex-head-to-head-coding-benchmark-comparison/) reports that Claude Opus 4.5 leads on the SWE-bench Verified benchmark with 80.9% accuracy, making it the first AI model to exceed 80% on this real-world coding test. The model demonstrates significant improvements in multi-step reasoning, coding throughput, and tool-use intelligence compared to previous Claude versions.
What pricing changes did Anthropic introduce with Claude Opus 4.5?
[venturebeat.com](https://venturebeat.com/ai/anthropics-claude-opus-4-5-is-here-cheaper-ai-infinite-chats-and-coding) reveals that Anthropic dramatically reduced pricing to $5 per million input tokens and $25 per million output tokens, compared to the previous rates of $15 and $75. This significant price reduction aims to make frontier AI capabilities more accessible to developers and enterprises.
What are the key reasoning enhancements in Claude Opus 4.5?
[datastudios.org](https://www.datastudios.org/post/claude-opus-4-5-new-model-architecture-reasoning-strength-long-context-memory-and-enterprise-scal) highlights that Opus 4.5 introduces an improved reasoning core capable of handling multi-phase tasks with sustained reasoning across dozens of steps. The model maintains coherence without drift, making it suitable for enterprise environments and autonomous agent frameworks that require complex, sequential decision-making.
