Subject: conversion: accept BitNetForCausalLM architecture name (#25769)
X-Git-Tag: upstream/0.0.10438~389
X-Git-Url: https://git.djapps.eu/?a=commitdiff_plain;h=3278e921b1e66f0b21f83cc993a1c66019f38b68;p=pkg%2Fggml%2Fsources%2Fllama.cpp

conversion: accept BitNetForCausalLM architecture name (#25769)

Microsoft BitNet Hugging Face configs use BitNetForCausalLM while the
converter only registered BitnetForCausalLM, causing conversion to fail
with "Model BitNetForCausalLM is not supported".

Register both spellings in TEXT_MODEL_MAP and the Bitnet model class.

Fixes ggml-org/llama.cpp#25629
