Most people think a better model means a bigger bill. Wrong. This time it flipped.
Here's the move. Anthropic made Claude Sonnet 5 the default in Claude Code. Update and it's already running.
🟠 Native 1M token context. It holds way more of your codebase at once, so it stops losing the thread on big builds.
🟠 Tuned for agentic and terminal work. It stays locked in through long, multi-step jobs.
🟠 It's the default. No config, no model picker.
The math. Intro pricing is $2 in and $10 out per million tokens through August 31. Lower price, stronger model.
One catch. That rate is promo. It climbs after August 31, so bank the habit while it's cheap.
Operators who switch today ship faster for less. Everyone else pays more for an older model.
Comment SONNET and I'll send the 5 jobs I'd run first on the 1M context.
