It is also necessary to emphasize that many optimizations are only possible in parts of the spec that are unobservable to user code. The alternative, like Bun "Direct Streams", is to intentionally diverge from the spec-defined observable behaviors. This means optimizations often feel "incomplete". They work in some scenarios but not in others, in some runtimes but not others, etc. Every such case adds to the overall unsustainable complexity of the Web streams approach which is why most runtime implementers rarely put significant effort into further improvements to their streams implementations once the conformance tests are passing.
No implicit type coercion. An int does not silently become a float. A float does not silently become a string. All conversions are explicit function calls — float_from_string, int(x), and so on. This prevents an entire category of subtle bugs where silent coercion produces unexpected results.

Google 仅以 PyTorch 格式发布了 FunctionGemma。我完成了整个转换流程，并上传了最终的 .task 文件：sasha-denisov/function-gemma-270M-it。这是 Google 的原始模型，未经微调。准确率约为 58%——虽然不算完美，但足以用于实验和原型开发。只想尝试在设备上调用函数？那就下载这个模型吧。
