Gemini 3.0 pro and Opus 4.5 both models are... far ahead in terms of coding specially frontend I am thinking about next sonnet 4.7 and gemini 3.0 pro GAshow more

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.show more

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:show more

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.show more

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.show more

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.show more

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.show more

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.show more

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 modelshow more

Perplexity's Sonar—built on Llama 3.3 70b—outperforms GPT-4o-mini and Claude... 3.5 Haiku while matching or surpassing top models like GPT-4o and Claude 3.5 Sonnet in user satisfaction. At 1200 tokens/second, Sonar is optimized for answer quality and speed.show more

Here’s Deepseek r1 1.5B thinking through a problem —... it’s comparable to 4o and Claude 3.5 Sonnet in a number of domains like math. Except… it’s a 1.5B model… and can run on virtually any hardware. Truly a huge efficiency leap.show more

Now it all makes sense, Claude Sonnet 4.5 can... keep its coding focus for nonstop 30 hours. And Dario Amodei just said few days back that, "The vast majority of code that is used to support Claude and to design the next Claude is now written by Claude. It's just the vast majority of it within Anthropic. And other fast moving companies, the same is true." The shift has started in all tech companies. --- From 'Axios' YT Channel.show more
