Haiku 4.5 is a workhorse that makes the coding experience in Claude Code feel really fast. While Sonnet 4.5 remains the default, Haiku 4.5 now powers the Explore subagent which can rapidly gather context on your codebase to build apps even faster.

anthropic just dropped claude haiku 4.5 and it absolutely COOKS with web design especially compared to haiku 3.5 basically on par with sonnet 4 (at 1/3 the price) they really nailed the cost + speed + quality ratio

Claude Haiku 4.5 is now live in Augment Code. In our internal evals, we found it delivered ~90% of Sonnet 4.5’s performance at 34% faster response speed. We're giving up to 20 free user messages over the next two weeks to everyone subscribed to a monthly paid plan once the pricing migration is complete — no action required. Rolling out today.

Fast tokens are the most valuable tokens. Because inference speed is productivity. And Cerebras makes the fastest tokens in the world. Google DeepMind's Gemma 4 runs at 1,500+ tokens per second on Cerebras — more than an order of magnitude faster than on GPUs and 15x faster than Claude Haiku 4.5. Private preview today. GA later this month. Build blazing fast multimodal apps.

Claude Sonnet 4.5 vs 4.0 (measured on coding tasks): App from scratch → 4.5: ~20min, functional build. → 4.0: 40+min, lower quality. Simple code change → 4.5: 3 tool calls, correct edit. → 4.0: longer chain, same result. Complex refactor → 4.5: faster + tests passed. → 4.0: slower + failed output. 4.5 reduces wasted cycles—less time waiting, fewer retries, more working code.

we created a claude agent that helps you build a fintech app from scratch, with just one simple prompt in claude code the subagent file was refined by opus 4.5, which distilled it down to a really simple, easy-to-follow guide even for humans the future is here, go build!

Claude Code with Sonnet 4.5 is actually incredible I gave it a prompt for a super complex app, and it one shot the entire thing In this video I walk you through how to use Claude Code to build a prompt library app you can start using immediately (no coding experience required):

The most hilarious part is that Claude Sonnet 4.5 is a gazillion times faster this way compared to using it via CC... The stats displayed in pi on the left are accumulative across all requests, while the context stats in CC are only for the last message.

"more than twice the speed" is underselling Haiku tbh built a way to directly compare Sonnet v Haiku 4.5 and it's roughly 3.5x faster, but the UX feels SO much better because Haiku stays inside the "flow window". obviously end to end latency varies a lot so Ant can't report a real number without production usage but you should try heads up comparisons

a little haiku 4.5 demo: cursor for design. this video is 2x speed because i'm slow at typing, but it's pretty fast at 1x too. feels nice to let claude edit the canvas faster than i could! now let's hope it gets a bit better at visual taste...

Tip: Ask Claude Code Community to use adapters, feature flags, and interfaces for implementations. 1. Model releases improve rapidly: 2024 June: Sonnet 3.5 2024 Oct: Sonnet 3.6 2025 Feb: Sonnet 3.7 2025 May: Sonnet/Opus 4 2025 Sept: Sonnet 4.5 Design key components around interfaces to do seamless rewrites with stronger released models. Use adapters and feature flags to gradually roll out usage. 2. There's tremendous value in simply updating api to use `claude-sonnet-4-5`. But remembering timeless software abstractions allows for the entire application to improve with the model. 3. Use Claude 4.5 Sonnet beyond code—it's a powerhouse for daily tasks. Try the Claude Chrome extension for forms, calendars, emails, or automating expense reports. These capabilities build on Sonnet 4.5's enhanced agentic capabilities making it easier to integrate to daily life. 4. We're living in a truly magical era, together. Enjoy the moment.
