Much better than Haiku 4.5. A bit better than Astra/Luna, a bit worse than Gemini Flash. www-cdn.anthropic.com/e1080d6bf5ae2… (page 50)

Every day, I get a lot of of emails and messages like this one. I try to respond to as many as I can. Sharing my response below, for anyone else in a similar situation. What do you think?

Just landed: /diff is now a persistent pane that you can scroll and click. It updates in real-time. For the times when you want to see the code without having to switch windows. Enjoy!

Fable 5.1 makes Claude Tag even more useful. Here it builds a last-minute leadership deck from a metrics spreadsheet and other data across Slack, spots a vendor report that disagrees with the numbers, and flags it before moving on. Claude Tag is available in Slack on Team and Enterprise plans.

I use xhigh, but many people actually prefer medium - a bit less intelligence but way less tokens and latency

I needed to book flights for a bunch of upcoming travel. As always, I used Claude Cowork to do it. In the past, Cowork has been decent at booking flights, but with Opus 4.7, for the first time ever, it 1-shotted it!

Clawd + last year’s umeshu (after letting it sit for 12 months, it turned out delicious!)

After a few hours, I had a PR. The results were solid -- P99 got 3x faster after porting to TypeScript!

14/ Use --agent to give Claude Code a custom system prompt & tools Custom agents are a powerful primitive that often gets overlooked. To use it, just define a new agent in .claude/agents, then run claude --agent=<your agent's name> code.claude.com/docs/en/sub-agents

9/ Use /btw for side queries I use this all the time to answer quick questions while the agent works
