Positron AI BF16 Checkpoint
This repository contains an unquantized bf16 checkpoint of openai/gpt-oss-20b published by Positron AI.
The upstream release of openai/gpt-oss-20b ships its weights in MXFP4; this checkpoint is that release dequantized to bf16 by Positron AI. No further quantization was applied.
Recommended Use
Use this artifact as a full-precision (bf16) reference or baseline for openai/gpt-oss-20b, for example when comparing quantized builds against an unquantized checkpoint. It is not a quantized build and carries no quantization configuration.
