SciChart founder here, we've added ChartGPU vs. SciChart to our performance test suite - it holds up pretty well, but SciChart still about an order of magnitude faster
Since the API is so new there may be some errors in the test suite, feel free to correct them
Innovation like this is fantastic btw and is good for the community! WebGPU is an awesome technology. So, this not only pushes us to be better but also consider how to add value to customers/users
Also, OpenRouter provides a list of free models: https://openrouter.ai/collections/free-models
