Im trying to work in adding webgou tests using cypress, but Im spending more time looking at this than anything else.

It should be fixed now via mlc-ai/mlc-llm#2187.

We recently used EMCC to include runtime code from https://github.com/mlc-ai/mlc-llm into the model WASM; as of now mainly for the grammar usages. Currently, I am prioritizing to ensure users who use the prebuilt models have a smooth experience. For instance, we introduced wasm versioning.

For compiling a customized model, as a current workaround, using the commits specified in the WASM version PRs should guarantee a working WASM (though admittedly a bit inconvenient):

• mlc-ai/binary-mlc-llm-libs#110
• mlc-ai/binary-mlc-llm-libs#118

In future, we will find ways to make sure that the compile-runtime flow is also smooth.
