How to use

from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "Motif-Technologies/motif-2.6b-v1.1-lc",
    trust_remote_code = True, 
    _attn_implementation = "eager", # also supports flash_attention_2
).cuda()

tokenizer = AutoTokenizer.from_pretrained(
    "Motif-Technologies/motif-2.6b-v1.1-lc", 
    trust_remote_code = True, 
)

        {'role': 'user', 'content': query},
    ],
    add_generation_prompt = True,
    return_tensors='pt',
).cuda()

output = model.generate(input_ids, max_new_tokens=1024, pad_token_id=tokenizer.eos_token_id)
output = tokenizer.decode(output[0, input_ids.shape[-1]:], skip_special_tokens = True)
