Everyone is dunking on Sonnet 5 for losing to Opus 4.8 on benchmarks. They're all making the same mistake, judging a teammate by a solo test. Sonnet 5 was never built to win alone. Set the model to Sonnet 5, effort to Ultracode, and any complex task auto-kicks a dynamic workflow where it plans, spawns agents, executes and checks its own work, fast and cheap. When Fable 5 comes back, the setup gets stupid good. Fable 5 decides what to build, Sonnet 5 actually builds it. You stop paying flagship prices to do grunt work.

We just launched Claude Sonnet 4.5 and “Imagine with Claude”, a 5-day preview that creates dynamic experiences for you in real-time (and the first product I’ve worked on at Anthropic!). It pioneers the concept of “model-as-backend”, using a model to not only generate interfaces on the fly but also power all the functionality behind it – all made possible by our newest model, Claude Sonnet 4.5. Here’s a "choose your own adventure" version of my founder journey, as retold by Imagine with Claude:

Grok 4.5 barely had time to enjoy first place. Grok 4.5 Medium just took the top spot on LaurenBench with 56.9%, beating Claude Sonnet 5, Claude Opus 5, GLM 5.2 and GPT 5.6 on real world agent tasks. And Elon says Grok 4.6 arrives next week. Looks like Grok 4.5 won’t be in the spotlight for long. xAI Grok / Writer: Annette, Grok Imagine Designer: Janné

Claude Sonnet 5 is live on Higgsfield. It plans and runs marketing asset pipelines on its own via Higgsfield MCP, at a level that used to need bigger, costlier models. It also makes agentic pipelines more efficient on Higgsfield Supercomputer.

Sonnet 4.5, meet Droid. After joint testing with Anthropic, we find the strengths of Sonnet 4.5 to be: • Significantly more reliable and accurate file editing • High environmental awareness • Snappier than previous models on quick questions, not overthinking simple asks Available across Factory's web and CLI now.

Introducing Claude Sonnet 5, our most agentic Sonnet yet. It makes plans, uses tools like browsers and terminals, and runs autonomously at a level that just a few months ago required larger and more expensive models.

Sonnet 5 is here. It's worse than Opus 4.8 on nearly every benchmark... Does that mean it's useless? Absolutely not. Use it with Claude Code Dynamic Workflows! 1. /model set to Sonnet 5 2. /effort set to Ultracode 3. Any complex task will kick off a dynamic workflow This will only become more powerful when Fable is back. You'll use Fable 5 as the superintelligent advisor and Sonnet 5 as the fast and efficient implementer.

Claude Fable 5 and GPT-5.6 are cooked already… Sonnet 5 vs Opus 4.8 on another agentic video pipeline. Both generated a storyboard with GPT Images 2.0, then fed it into Seedance 2.0, all through Higgsfield MCP on Claude. Same quality, but each directed Seedance 2.0 completely differently.

New Claude Sonnet 5 performs at GPT 5.5 level 6x cheaper! We gave 4 models the same prompt: build three self-contained HTML5 canvas scenes with real physics crash demos Prompts: - A car crashes into a brick wall - A wrecking ball destroys a house - A catapult throws a rock at a castle wall Outputs: Sonnet 5: 15,047 tokens, $0.15 Opus 4.8: 23,063 tokens, $0.58 Sonnet 4.6: 25,824 tokens, $0.39 GPT 5.5: 31,152 tokens, $0.94 Sonnet 5 did as well as Opus 4.8 and GPT 5.5 on all three tests. In the wrecking ball test, it beat Opus 4.8. The cable moves smoothly and every hit connects. In the catapult test, it beat GPT 5.5. The rock always lands inside the wall. Sonnet 5 still needs better detail and graphics. But it used fewer tokens than every other model
