from langchain_community.llms import HuggingFaceHub

hf=HuggingFaceHub(
    repo_id="google/flan-t5-large",
    task="text2text-generation",  # Explicitly specify the task
    model_kwargs={"temperature":0.7,"max_length":100},
    huggingfacehub_api_token="hf_... Ue"

)
text="What is the capital of Turkey"

output=hf.invoke(text)
print(output)

ValueError: Task text2text-generation has no recommended model. Please specify a model explicitly. Visit Tasks - Hugging Face for more info.

Why I am getting this error. I just checked Api token multiple times and still give this error.

try this one:

from langchain_huggingface.llms.huggingface_endpoint import HuggingFaceEndpoint
llm = HuggingFaceEndpoint(
    task='text-generation',
    model="deepseek-ai/DeepSeek-R1",
    max_new_tokens=100,
    temperature=0.7,
    huggingfacehub_api_token="your_api"
)
print(llm.invoke("What is the capital of Turkey"))

The token has been leaked. Please invalidate the token as soon as possible.

If the same solution as above is okay, this should work. The error message says that you can just overwrite the task.

from langchain_huggingface.llms.huggingface_endpoint import HuggingFaceEndpoint
chain = LLMChain(
    llm = HuggingFaceEndpoint(
        task='text-generation', # overwrite task
        model="deepseek-ai/DeepSeek-R1",
        temperature=0,
        huggingfacehub_api_token="hf_*****"
    ),
    prompt=prompt
)
