Turns out you can eliminate the purple LLM-slop design aesthetic with good prompting + claude skills.
We wrote a short post on it with more details: https://t.co/Z50wtwxcmC
2023 was the year of the chatbot.
2024 was the year of RAG and finetuning.
2025 has been the year of MCP and tool use.
2026 will be the year of the computer environment and filesystem.
The great thing about spreadsheets is they're structured, primarily text based, and often contain verifiable answers. They're on their way to being a solved problem.
Very bullish for AI financial products like Claude for Financial Services.
Today we're introducing Skills in claude dot ai, Claude Code, and the API.
Skills let you package specialized knowledge into reusable capabilities that Claude loads on demand as agents tackle more complex tasks.
Here's how they work and why they matter for the future of agents:
Introducing Claude Haiku 4.5.
Our latest small model that matches Sonnet 4's performance at a third of the cost and more than twice the speed. https://t.co/JREePxuKSU
Over these next few years it's going to become more and more important that you resist letting slop consume you.
Keep creating. Keep learning. Keep thinking.
We’re running a “Built with Claude Sonnet 4.5” challenge.
We want to see the coolest things you can build with 4.5 in the next week.
Four winners will receive one year of Claude Max 20x and $1k in Claude API credits. https://t.co/rPakwKD4Uc
"Claude please make a discounted cash flow financial model. Make no mistakes."
I've never made a financial model in my life before this and Claude one shots a 9-sheet workbook complete with formulas for me. Vibe excel era. https://t.co/us61ak2uPg
Claude can now create and edit files from spreadsheets and documents to PDFs and slide decks.
What coding agents have been doing for software engineering is soon expanding to all knowledge work - this is just the beginning. https://t.co/ajaJcX7Gsu
Claude Sonnet 4 now supports a 1 million token context window on the Anthropic API.
Process over 75,000 lines of code or hundreds of documents in a single request.
Say hello to Claude Opus 4.1, our best model yet for real-world coding, reasoning, and agentic tasks.
The frontier continues to move forward one update at a time. https://t.co/YUilH7IC3z
We’re rolling out more updates to Claude Code.
First, the GitHub Actions integration is now available to Pro and Max plan users (in addition to pay-as-you-go API users).

Introducing Anthropic courses.
We've launched a free educational platform to help you learn everything about Claude - from using the Anthropic API to MCP to Claude Code best practices. https://t.co/5l6NG9qDbB
Heard this quote at a dinner recently:
"I used to think Claude Code was too expensive compared to other dev tools. But after Opus 4, I realized it's actually very affordable compared to what you'd pay a junior software engineer."
It feels important to note that we're nearing a
