[D] What are the current state of the art code embedding models?

Does anyone know what the best models/benchmarks are for semantic code similarity search? In particular I'd like to find a model that is trained primarily for c/c++ code, such that the embeddings could be used to compare how similar a particular function is to other another function, and also to compare similarity with natural language descriptions. I came across Code T5, which looks quite good. But it isn't clear how much c/c++ code was used during training (it seems like …
