Hi, I am working on iterative summarisation of long documents using Qwen/Qwen2.5-14B-Instruct-1M via langchain’s HuggingFaceEndpoint. Despite using an access token from a Pro account to login, I get the following error: Error processing batch 1: 402, message=‘Payment Required’, url=‘ https://route…

Hey Fyahdii! That 402 error with the “Invalid username or password” message is odd, especially with a Pro account. I’ve hit similar issues with Hugging Face’s API when the token wasn’t set up right. Check that your HUGGINGFACEHUB_API_TOKEN is correctly loaded in your environment (e.g., via os.enviro…

For 402 error, refer this: [image] Hugging Face Payment Error 402 & You've Exceeded Monthly Quota Languages at Hugging Face Whenever I want generate a response from the api it shows payment error 402 and this link “ https://huggingface.co/api/inference-proxy/hf-inference/mo…

Thank you for responding and for your help. I think I have been able to resolve this by generating a new token and using that one instead.

Nevermind the error came back again

Here is my code snippet: llm = HuggingFaceEndpoint( repo_id=“Qwen/Qwen2.5-14B-Instruct-1M”, task=“text-generation”, max_new_tokens=20, do_sample=False, repetition_penalty=1.03, temperature=0.00 ) chat = ChatHuggingFace(llm=llm, verbose=True)

It seems that this may also occur due to permission settings on Hugging Face’s side? [image] 402 Client Error: Payment Required for url: https://huggingface.co/proxy/router.huggingface.co/hf-inference/models/meta-llama/Llama-3.3-70B-Instruct/v1/chat/completions (Request ID: Root=1-67e420cf-1ec0ac…

Thanks for your help. Based on the linked post, the token I am using appears to have the correct permissions, and there is a payment method with an active subscription on the account, so I suspect it’s most likely something else. Do you know how I might check the permission settings?

Hmm… I don’t know how to check that on the user side… It may be quicker to contact Hugging Face. @meganariley billing@huggingface.co
