'GPT' is the class name nanoGPT's model.py exports, so this key covers any upload that saves nanoGPT's own state dict. Not an alias of GPT2LMHeadModel: the config uses nanoGPT's keys (n_embd 384, n_layer 6, n_head 8, block_size 256, bias, dropout) rather than GPT2Config's n_positions/n_ctx, the repo carries only a pickled pytorch_model.bin (no safetensors, no tokenizer files; the card names tiktoken gpt2), and nanoGPT stores nn.Linear weights where GPT-2's checkpoint stores Conv1D (transposed), so the gpt2 converter would read every projection the wrong way round. Nothing at the pin registers the class. Declined on 2026-11-09 under engine #1667; the census reports it as . REVIEWED. Remove this entry if a backend gains a nanoGPT import.",
