Claude Sonnet 5.5
Anthropic 今天推出了新的 Sonnet 5.5 模型。他们表示，该模型“运行速度提高了30%以上，大多数工作成本最多降低30%”，其定价与 Sonnet 5 相同，但似乎在所有基准测试中都优于 Sonnet 5，运行成本也更低。这里有一些火烈鸟骑自行车的图片。Sonnet 5.5 与 Opus 5.5 有相同的错误：在“最大”思考力度下，火烈鸟思考了128,000个标记（花费1.28美元）后耗尽标记，未能生成SVG。这是它在“xhigh”思考力度下给出的火烈鸟，花费了5.74美分，耗时41秒：Sonnet 5.5 在一些编码任务上几乎与 Opus 5.5 相当，包括各种流行的3D动画技巧。Sonnet 5.5 最有趣的地方是，它现在是 claude.ai 免费层级所使用的模型。OpenAI 的 ChatGPT 免费层级使用的是 Luna 5.6，这意味着 Anthropic 目前拥有更强大的免费产品。我将这个提示发送到该免费层级：用 WebGL 为我构建一个显示三维火烈鸟骑自行车的 HTML 页面，然后得到了这个页面，这是一项扎实的工作。Anthropic 的公告重申，Haiku 5.5 将会在“下周内”推出。
Claude Sonnet 5.5 New Sonnet model from Anthropic today. They say it "runs 30%+ faster, and costs up to 30% less for most work" - it's priced the same as Sonnet 5 but appears to beat it on every benchmark, and should be cheaper to run as well. Here are some pelicans riding bicycles . Sonnet 5.5 suffered from the same bug as Opus 5.5 : the "max" thinking effort pelican thought for 128,000 tokens (at a cost of $1.28) before running out of tokens and failing to produce an SVG. Here's the pelican it gave me for thinking effort "xhigh", at a cost of 5.74 cents and taking 41 seconds: Sonnet 5.5 appears to be almost as good as Opus 5.5 on some coding tasks, including various viral 3D animation tricks . The most interesting thing about Sonnet 5.5 is that it's now the model used for the free tier on claude.ai . OpenAI's ChatGPT free tier uses Luna 5.6, which means Anthropic currently have a much more capable free offering. I ran this prompt against that free tier: build me an HTML page that renders a three-dimensional pelican riding a bicycle using WebGL And got back this page , which is a solid effort. Anthropic's announcement reiterates that Haiku 5.5 will be available "in the coming week
