open-jev-deberta-v3-large vs Qwen-2.5-1B-RLCD

What actually separates them

1. They produce their confidence differently

   open-jev-deberta-v3-large is an encoder and Qwen-2.5-1B-RLCD is a decoder. An encoder scores every option in one forward pass, so the probability it returns is defined over the whole option set by construction. A decoder reaches an answer by generating, so a usable probability needs constrained decoding plus a normalisation step over the options. Two decoders can report incomparable confidences while both being honest. That difference is invisible in an accuracy number and decisive if you intend to route on confidence.

2. Only one of them ships in a runnable local format

   Qwen-2.5-1B-RLCD has builds in MLX, so it runs without a Python stack. open-jev-deberta-v3-large ships original weights only, which means converting it yourself before it goes anywhere constrained.

3. Neither has been measured by anyone independent

   Both are days old and every figure in circulation about either was published by the people who trained it. The table above is what can be checked from repository metadata. Everything else about these two is currently unknown.
