LLaMA 3.3 Gated Repo Access: Read Token Authentication & Resumable Download Pipeline

🔒 What is a Gated Repository?

LLaMA 3.3 (70B-Instruct) launched by Meta retains strong performance while continuing Meta AI’s open source usage agreement (Meta LLaMA Community License). To comply with compliance review requirements, such repositories are marked as Gated Model on Hugging Face Hub.

Anonymous access requests that are not authorized by the official protocol will trigger HTTP 401 Unauthorized (unauthenticated) or HTTP 403 Forbidden (unsigned permission) errors when pulling directly.

Core mechanism: The access control mechanism is the policy determination of the official warehouse authority system, and a compliance agreement must be signed on the official platform. The mirror site HF-Mirror adheres to the transparent proxy principle and supports the safe and transparent transmission of user credentials, but will not bypass the official basic permission review.

🔑 Apply for permission and generate read-only Access Token

Sign the agreement: Visit the official model homepage (for example https://huggingface.co/meta-llama/Llama-3.3-70B-Instruct), log in to your personal account and fill in the basic information (name, organization, country) and click submit application. The system usually approves automatically within a few minutes.
Generate Access Token: Click the avatar in the upper right corner → Settings → Access Tokens → Click Create new token.
Principle of Minimizing Permissions: Select the Token type as Read (read-only). When downloading models on a daily basis, do not use a token with write permission (Write) to prevent sensitive credentials from being leaked.

🌐 The transparent authentication principle of HF-Mirror mirror station

Many developers will have questions: "When configuring a token on a mirror site, will the password and credentials be intercepted by the mirror site server?"

HF-Mirror adopts a stateless reverse proxy architecture:

[Local Host CLI / SDK]
    ↓ (With Authorization: Bearer hf_xxx Header)
[HF-Mirror Edge Gateway (hf-mirror.net)]
    ↓ (Zero-Mod Streaming Passthrough, zero disk storage, zero database logging)
[Hugging Face Official Auth Center (huggingface.co)]
    ↓ (Returns valid 200 OK status + CDN file redirect)
[Accelerated data stream flows through backbone transit directly to client]

The access log recording of sensitive request headers (Headers) is explicitly turned off in the underlying Web routing rules of the mirror site, fully protecting the privacy of developer credentials.

💻 Complete practical operation of breakpoint resume transfer with Token

📌 Method 1: Via environment variables (recommended, best for scripting and automation)

Terminal command: environment variable passes Token

# 1. Set up the mirror source
export HF_ENDPOINT="https://hf-mirror.net"

# 2. Inject your official read-only Token (starting with hf_)
export HF_TOKEN="hf_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

# 3. Start downloading LLaMA 3.3 70B
huggingface-cli download meta-llama/Llama-3.3-70B-Instruct \
  --local-dir /data/models/Llama-3.3-70B-Instruct \
  --local-dir-use-symlinks False \
  --resume-download

📌 Method 2: Global login via huggingface-cli login

Command line interactive login

# Set up mirroring
export HF_ENDPOINT="https://hf-mirror.net"

# Interactive login (Token will be stored in ~/.cache/huggingface/token)
huggingface-cli login

# Tip: Token: Enter your hf_xxx (it will not be echoed when typing, just press Enter)
# Tip: Add token as git credential? (Y/n) just select n

🛠️ High Frequency Error Diagnosis Checklist

HTTP 401 Client Error: Repository Not Found or Unauthorized

Explanation No Token was passed or the Token string was truncated by extra spaces. Please check if the variable exists via echo $HF_TOKEN.
HTTP 403 Client Error: You don't have access to this gated repo

It means that the Token is valid, but your account has not yet completed the agreement signing on the official model page, or the application is still under review and approval. Please log in to the official website to confirm whether the green Granted mark appears on the model homepage.
