* Allow getting the HF file from the HF repo with tag (like ollama), for example:
|
|
* - bartowski/Llama-3.2-3B-Instruct-GGUF:q4
|
|
* - bartowski/Llama-3.2-3B-Instruct-GGUF:Q4_K_M
|
|
* - bartowski/Llama-3.2-3B-Instruct-GGUF:q5_k_s
|
|
* Tag is optional, default to "latest" (meaning it checks for Q4_K_M first, then Q4, then if not found, return the first GGUF file in repo)
|
|
*
|
|
* Return pair of <repo, file> (with "repo" already having tag removed)
|
|
*
|
|
* Note: we use the Ollama-compatible HF API, but not using the blobId. Instead, we use the special "ggufFile" field which returns the value for "hf_file". This is done to be backward-compatible with existing cache files.
