Running Workloads on Hugging Face Jobs Overview
Run any workload on fully managed Hugging Face infrastructure. No local setup required—jobs run on cloud CPUs, GPUs, or TPUs and can persist results to the Hugging Face Hub.
Common use cases:
Data Processing - Transform, filter, or analyze large datasets Batch Inference - Run inference on thousands of samples Experiments & Benchmarks - Reproducible ML experiments Model Training - Fine-tune models (see model-trainer skill for TRL-specific training) Synthetic Data Generation - Generate datasets using LLMs Development & Testing - Test code without local GPU setup Scheduled Jobs - Automate recurring tasks
For model training specifically: See the model-trainer skill for TRL-based training workflows.
When to Use This Skill
Use this skill when users want to:
Run Python workloads on cloud infrastructure Execute jobs without local GPU/TPU setup Process data at scale Run batch inference or experiments Schedule recurring tasks Use GPUs/TPUs for any workload Persist results to the Hugging Face Hub Key Directives
When assisting with jobs:
ALWAYS use hf_jobs() MCP tool - Submit jobs using hf_jobs("uv", {...}) or hf_jobs("run", {...}). The script parameter accepts Python code directly. Do NOT save to local files unless the user explicitly requests it. Pass the script content as a string to hf_jobs().
Always handle authentication - Jobs that interact with the Hub require HF_TOKEN via secrets. See Token Usage section below.
Provide job details after submission - After submitting, provide job ID, monitoring URL, estimated time, and note that the user can request status checks later.
Set appropriate timeouts - Default 30min may be insufficient for long-running tasks.
Prerequisites Checklist
Before starting any job, verify:
✅ Account & Authentication Hugging Face Account with Pro, Team, or Enterprise plan (Jobs require paid plan) Authenticated login: Check with hf_whoami() HF_TOKEN for Hub Access ⚠️ CRITICAL - Required for any Hub operations (push models/datasets, download private repos, etc.) Token must have appropriate permissions (read for downloads, write for uploads) ✅ Token Usage (See Token Usage section for details)
When tokens are required:
Pushing models/datasets to Hub Accessing private repositories Using Hub APIs in scripts Any authenticated Hub operations
How to provide tokens:
{ "secrets": {"HF_TOKEN": "$HF_TOKEN"} # Recommended: automatic token }
⚠️ CRITICAL: The $HF_TOKEN placeholder is automatically replaced with your logged-in token. Never hardcode tokens in scripts.
Token Usage Guide Understanding Tokens
What are HF Tokens?
Authentication credentials for Hugging Face Hub Required for authenticated operations (push, private repos, API access) Stored securely on your machine after hf auth login
Token Types:
Read Token - Can download models/datasets, read private repos Write Token - Can push models/datasets, create repos, modify content Organization Token - Can act on behalf of an organization When Tokens Are Required
Always Required:
Pushing models/datasets to Hub Accessing private repositories Creating new repositories Modifying existing repositories Using Hub APIs programmatically
Not Required:
Downloading public models/datasets Running jobs that don't interact with Hub Reading public repository information How to Provide Tokens to Jobs Method 1: Automatic Token (Recommended) hf_jobs("uv", { "script": "your_script.py", "secrets": {"HF_TOKEN": "$HF_TOKEN"} # ✅ Automatic replacement })
How it works:
$HF_TOKEN is a placeholder that gets replaced with your actual token Uses the token from your logged-in session (hf auth login) Most secure and convenient method Token is encrypted server-side when passed as a secret
Benefits:
No token exposure in code Uses your current login session Automatically updated if you re-login Works seamlessly with MCP tools Method 2: Explicit Token (Not Recommended) hf_jobs("uv", { "script": "your_script.py", "secrets": {"HF_TOKEN": "hf_abc123..."} # ⚠️ Hardcoded token })
When to use:
Only if automatic token doesn't work Testing with a specific token Organization tokens (use with caution)
Security concerns:
Token visible in code/logs Must manually update if token rotates Risk of token exposure Method 3: Environment Variable (Less Secure) hf_jobs("uv", { "script": "your_script.py", "env": {"HF_TOKEN": "hf_abc123..."} # ⚠️ Less secure than secrets })
Difference from secrets:
env variables are visible in job logs secrets are encrypted server-side Always prefer secrets for tokens Using Tokens in Scripts
In your Python script, tokens are available as environment variables:
/// script
dependencies = ["huggingface-hub"]
///
import os from huggingface_hub import HfApi
Token is automatically available if passed via secrets
token = os.environ.get("HF_TOKEN")
Use with Hub API
api = HfApi(token=token)
Or let huggingface_hub auto-detect
api = HfApi() # Automatically uses HF_TOKEN env var
Best practices:
Don't hardcode tokens in scripts Use os.environ.get("HF_TOKEN") to access Let huggingface_hub auto-detect when possible Verify token exists before Hub operations Token Verification
Check if you're logged in:
from huggingface_hub import whoami user_info = whoami() # Returns your username if authenticated
Verify token in job:
import os assert "HF_TOKEN" in os.environ, "HF_TOKEN not found!" token = os.environ["HF_TOKEN"] print(f"Token starts with: {token[:7]}...") # Should start with "hf_"
Common Token Issues
Error: 401 Unauthorized
Cause: Token missing or invalid Fix: Add secrets={"HF_TOKEN": "$HF_TOKEN"} to job config Verify: Check hf_whoami() works locally
Error: 403 Forbidden
Cause: Token lacks required permissions Fix: Ensure token has write permissions for push operations Check: Token type at https://huggingface.co/settings/tokens
Error: Token not found in environment
Cause: secrets not passed or wrong key name Fix: Use secrets={"HF_TOKEN": "$HF_TOKEN"} (not env) Verify: Script checks os.environ.get("HF_TOKEN")
Error: Repository access denied
Cause: Token doesn't have access to private repo Fix: Use token from account with access Check: Verify repo visibility and your permissions Token Security Best Practices Never commit tokens - Use $HF_TOKEN placeholder or environment variables Use secrets, not env - Secrets are encrypted server-side Rotate tokens regularly - Generate new tokens periodically Use minimal permissions - Create tokens with only needed permissions Don't share tokens - Each user should use their own token Monitor token usage - Check token activity in Hub settings Complete Token Example
Example: Push results to Hub
hf_jobs("uv", { "script": """
/// script
dependencies = ["huggingface-hub", "datasets"]
///
import os from huggingface_hub import HfApi from datasets import Dataset
Verify token is available
assert "HF_TOKEN" in os.environ, "HF_TOKEN required!"
Use token for Hub operations
api = HfApi(token=os.environ["HF_TOKEN"])
Create and push dataset
data = {"text": ["Hello", "World"]} dataset = Dataset.from_dict(data) dataset.push_to_hub("username/my-dataset", token=os.environ["HF_TOKEN"])
print("✅ Dataset pushed successfully!") """, "flavor": "cpu-basic", "timeout": "30m", "secrets": {"HF_TOKEN": "$HF_TOKEN"} # ✅ Token provided securely })
Quick Start: Two Approaches Approach 1: UV Scripts (Recommended)
UV scripts use PEP 723 inline dependencies for clean, self-contained workloads.
MCP Tool:
hf_jobs("uv", { "script": """
/// script
dependencies = ["transformers", "torch"]
///
from transformers import pipeline import torch
Your workload here
classifier = pipeline("sentiment-analysis") result = classifier("I love Hugging Face!") print(result) """, "flavor": "cpu-basic", "timeout": "30m" })
CLI Equivalent:
hf jobs uv run my_script.py --flavor cpu-basic --timeout 30m
Python API:
from huggingface_hub import run_uv_job run_uv_job("my_script.py", flavor="cpu-basic", timeout="30m")
Benefits: Direct MCP tool usage, clean code, dependencies declared inline, no file saving required
When to use: Default choice for all workloads, custom logic, any scenario requiring hf_jobs()
Custom Docker Images for UV Scripts
By default, UV scripts use ghcr.io/astral-sh/uv:python3.12-bookworm-slim. For ML workloads with complex dependencies, use pre-built images:
hf_jobs("uv", { "script": "inference.py", "image": "vllm/vllm-openai:latest", # Pre-built image with vLLM "flavor": "a10g-large" })
CLI:
hf jobs uv run --image vllm/vllm-openai:latest --flavor a10g-large inference.py
Benefits: Faster startup, pre-installed dependencies, optimized for specific frameworks
Python Version
By default, UV scripts use Python 3.12. Specify a different version:
hf_jobs("uv", { "script": "my_script.py", "python": "3.11", # Use Python 3.11 "flavor": "cpu-basic" })
Python API:
from huggingface_hub import run_uv_job run_uv_job("my_script.py", python="3.11")
Working with Scripts
⚠️ Important: There are two "script path" stories depending on how you run Jobs:
Using the hf_jobs() MCP tool (recommended in this repo): the script value must be inline code (a string) or a URL. A local filesystem path (like "./scripts/foo.py") won't exist inside the remote container. Using the hf jobs uv run CLI: local file paths do work (the CLI uploads your script).
Common mistake with hf_jobs() MCP tool:
❌ Will fail (remote container can't see your local path)
hf_jobs("uv", {"script": "./scripts/foo.py"})
Correct patterns with hf_jobs() MCP tool:
✅ Inline: read the local script file and pass its contents
from pathlib import Path script = Path("hf-jobs/scripts/foo.py").read_text() hf_jobs("uv", {"script": script})
✅ URL: host the script somewhere reachable
hf_jobs("uv", {"script": "https://huggingface.co/datasets/uv-scripts/.../raw/main/foo.py"})
✅ URL from GitHub
hf_jobs("uv", {"script": "https://raw.githubusercontent.com/huggingface/trl/main/trl/scripts/sft.py"})
CLI equivalent (local paths supported):
hf jobs uv run ./scripts/foo.py -- --your --args
Adding Dependencies at Runtime
Add extra dependencies beyond what's in the PEP 723 header:
hf_jobs("uv", { "script": "inference.py", "dependencies": ["transformers", "torch>=2.0"], # Extra deps "flavor": "a10g-small" })
Python API:
from huggingface_hub import run_uv_job run_uv_job("inference.py", dependencies=["transformers", "torch>=2.0"])
Approach 2: Docker-Based Jobs
Run jobs with custom Docker images and commands.
MCP Tool:
hf_jobs("run", { "image": "python:3.12", "command": ["python", "-c", "print('Hello from HF Jobs!')"], "flavor": "cpu-basic", "timeout": "30m" })
CLI Equivalent:
hf jobs run python:3.12 python -c "print('Hello from HF Jobs!')"
Python API:
from huggingface_hub import run_job run_job(image="python:3.12", command=["python", "-c", "print('Hello!')"], flavor="cpu-basic")
Benefits: Full Docker control, use pre-built images, run any command When to use: Need specific Docker images, non-Python workloads, complex environments
Example with GPU:
hf_jobs("run", { "image": "pytorch/pytorch:2.6.0-cuda12.4-cudnn9-devel", "command": ["python", "-c", "import torch; print(torch.cuda.get_device_name())"], "flavor": "a10g-small", "timeout": "1h" })
Using Hugging Face Spaces as Images:
You can use Docker images from HF Spaces:
hf_jobs("run", { "image": "hf.co/spaces/lhoestq/duckdb", # Space as Docker image "command": ["duckdb", "-c", "SELECT 'Hello from DuckDB!'"], "flavor": "cpu-basic" })
CLI:
hf jobs run hf.co/spaces/lhoestq/duckdb duckdb -c "SELECT 'Hello!'"

Workload Type Recommended Hardware Use Case Data processing, testing cpu-basic, cpu-upgrade Lightweight tasks Small models, demos t4-small <1B models, quick tests Medium models t4-medium, l4x1 1-7B models Large models, production a10g-small, a10g-large 7-13B models Very large models a100-large 13B+ models Batch inference a10g-large, a100-large High-throughput Multi-GPU workloads l4x4, a10g-largex2, a10g-largex4 Parallel/large models TPU workloads v5e-1x1, v5e-2x2, v5e-2x4 JAX/Flax, TPU-optimized
All Available Flavors:
CPU: cpu-basic, cpu-upgrade GPU: t4-small, t4-medium, l4x1, l4x4, a10g-small, a10g-large, a10g-largex2, a10g-largex4, a100-large TPU: v5e-1x1, v5e-2x2, v5e-2x4
Guidelines:
Start with smaller hardware for testing Scale up based on actual needs Use multi-GPU for parallel workloads or large models Use TPUs for JAX/Flax workloads See references/hardware_guide.md for detailed specifications Critical: Saving Results
⚠️ EPHEMERAL ENVIRONMENT—MUST PERSIST RESULTS
The Jobs environment is temporary. All files are deleted when the job ends. If results aren't persisted, ALL WORK IS LOST.
Persistence Options
- Push to Hugging Face Hub (Recommended)
Push models
model.push_to_hub("username/model-name", token=os.environ["HF_TOKEN"])
Push datasets
dataset.push_to_hub("username/dataset-name", token=os.environ["HF_TOKEN"])
Push artifacts
api.upload_file( path_or_fileobj="results.json", path_in_repo="results.json", repo_id="username/results", token=os.environ["HF_TOKEN"] )
- Use External Storage
Upload to S3, GCS, etc.
import boto3 s3 = boto3.client('s3') s3.upload_file('results.json', 'my-bucket', 'results.json')
- Send Results via API
POST results to your API
import requests requests.post("https://your-api.com/results", json=results)
Required Configuration for Hub Push
In job submission:
{ "secrets": {"HF_TOKEN": "$HF_TOKEN"} # Enables authentication }
In script:
import os from huggingface_hub import HfApi
Token automatically available from secrets
api = HfApi(token=os.environ.get("HF_TOKEN"))
Push your results
api.upload_file(...)
Verification Checklist
Before submitting:
Results persistence method chosen secrets={"HF_TOKEN": "$HF_TOKEN"} if using Hub Script handles missing token gracefully Test persistence path works
See: references/hub_saving.md for detailed Hub persistence guide
Timeout Management
⚠️ DEFAULT: 30 MINUTES
Jobs automatically stop after the timeout. For long-running tasks like training, always set a custom timeout.
Setting Timeouts
MCP Tool:
{ "timeout": "2h" # 2 hours }
Supported formats:
Integer/float: seconds (e.g., 300 = 5 minutes) String with suffix: "5m" (minutes), "2h" (hours), "1d" (days) Examples: "90m", "2h", "1.5h", 300, "1d"
Python API:
from huggingface_hub import run_job, run_uv_job
run_job(image="python:3.12", command=[...], timeout="2h") run_uv_job("script.py", timeout=7200) # 2 hours in seconds
Timeout Guidelines Scenario Recommended Notes Quick test 10-30 min Verify setup Data processing 1-2 hours Depends on data size Batch inference 2-4 hours Large batches Experiments 4-8 hours Multiple runs Long-running 8-24 hours Production workloads
Always add 20-30% buffer for setup, network delays, and cleanup.
On timeout: Job killed immediately, all unsaved progress lost
Cost Estimation
General guidelines:
Total Cost = (Hours of runtime) × (Cost per hour)
Example calculations:
Quick test:
Hardware: cpu-basic ($0.10/hour) Time: 15 minutes (0.25 hours) Cost: $0.03
Data processing:
Hardware: l4x1 ($2.50/hour) Time: 2 hours Cost: $5.00
Batch inference:
Hardware: a10g-large ($5/hour) Time: 4 hours Cost: $20.00
Cost optimization tips:
Start small - Test on cpu-basic or t4-small Monitor runtime - Set appropriate timeouts Use checkpoints - Resume if job fails Optimize code - Reduce unnecessary compute Choose right hardware - Don't over-provision Monitoring and Tracking Check Job Status
MCP Tool:
List all jobs
hf_jobs("ps")
Inspect specific job
hf_jobs("inspect", {"job_id": "your-job-id"})
View logs
hf_jobs("logs", {"job_id": "your-job-id"})
Cancel a job
hf_jobs("cancel", {"job_id": "your-job-id"})
Python API:
from huggingface_hub import list_jobs, inspect_job, fetch_job_logs, cancel_job
List your jobs
jobs = list_jobs()
List running jobs only
running = [j for j in list_jobs() if j.status.stage == "RUNNING"]
Inspect specific job
job_info = inspect_job(job_id="your-job-id")
View logs
for log in fetch_job_logs(job_id="your-job-id"): print(log)
Cancel a job
cancel_job(job_id="your-job-id")
CLI:
hf jobs ps # List jobs
hf jobs logs
Remember: Wait for user to request status checks. Avoid polling repeatedly.
Job URLs
After submission, jobs have monitoring URLs:
https://huggingface.co/jobs/username/job-id
View logs, status, and details in the browser.
Wait for Multiple Jobs import time from huggingface_hub import inspect_job, run_job
Run multiple jobs
jobs = [run_job(image=img, command=cmd) for img, cmd in workloads]
Wait for all to complete
for job in jobs: while inspect_job(job_id=job.id).status.stage not in ("COMPLETED", "ERROR"): time.sleep(10)
Scheduled Jobs
Run jobs on a schedule using CRON expressions or predefined schedules.
MCP Tool:
Schedule a UV script that runs every hour
hf_jobs("scheduled uv", { "script": "your_script.py", "schedule": "@hourly", "flavor": "cpu-basic" })
Schedule with CRON syntax
hf_jobs("scheduled uv", { "script": "your_script.py", "schedule": "0 9 * * 1", # 9 AM every Monday "flavor": "cpu-basic" })
Schedule a Docker-based job
hf_jobs("scheduled run", { "image": "python:3.12", "command": ["python", "-c", "print('Scheduled!')"], "schedule": "@daily", "flavor": "cpu-basic" })
Python API:
from huggingface_hub import create_scheduled_job, create_scheduled_uv_job
Schedule a Docker job
create_scheduled_job( image="python:3.12", command=["python", "-c", "print('Running on schedule!')"], schedule="@hourly" )
Schedule a UV script
create_scheduled_uv_job("my_script.py", schedule="@daily", flavor="cpu-basic")
Schedule with GPU
create_scheduled_uv_job( "ml_inference.py", schedule="0 /6 * * ", # Every 6 hours flavor="a10g-small" )
Available schedules:
@annually, @yearly - Once per year @monthly - Once per month @weekly - Once per week @daily - Once per day @hourly - Once per hour CRON expression - Custom schedule (e.g., "/5 * * * " for every 5 minutes)
Manage scheduled jobs:
MCP Tool
hf_jobs("scheduled ps") # List scheduled jobs hf_jobs("scheduled inspect", {"job_id": "..."}) # Inspect details hf_jobs("scheduled suspend", {"job_id": "..."}) # Pause hf_jobs("scheduled resume", {"job_id": "..."}) # Resume hf_jobs("scheduled delete", {"job_id": "..."}) # Delete
Python API for management:
from huggingface_hub import ( list_scheduled_jobs, inspect_scheduled_job, suspend_scheduled_job, resume_scheduled_job, delete_scheduled_job )
List all scheduled jobs
scheduled = list_scheduled_jobs()
Inspect a scheduled job
info = inspect_scheduled_job(scheduled_job_id)
Suspend (pause) a scheduled job
suspend_scheduled_job(scheduled_job_id)
Resume a scheduled job
resume_scheduled_job(scheduled_job_id)
Delete a scheduled job
delete_scheduled_job(scheduled_job_id)
Webhooks: Trigger Jobs on Events
Trigger jobs automatically when changes happen in Hugging Face repositories.
Python API:
from huggingface_hub import create_webhook
Create webhook that triggers a job when a repo changes
webhook = create_webhook( job_id=job.id, watched=[ {"type": "user", "name": "your-username"}, {"type": "org", "name": "your-org-name"} ], domains=["repo", "discussion"], secret="your-secret" )
How it works:
Webhook listens for changes in watched repositories When triggered, the job runs with WEBHOOK_PAYLOAD environment variable Your script can parse the payload to understand what changed
Use cases:
Auto-process new datasets when uploaded Trigger inference when models are updated Run tests when code changes Generate reports on repository activity
Access webhook payload in script:
import os import json
payload = json.loads(os.environ.get("WEBHOOK_PAYLOAD", "{}")) print(f"Event type: {payload.get('event', {}).get('action')}")
See Webhooks Documentation for more details.
Common Workload Patterns
This repository ships ready-to-run UV scripts in hf-jobs/scripts/. Prefer using them instead of inventing new templates.
Pattern 1: Dataset → Model Responses (vLLM) — scripts/generate-responses.py
What it does: loads a Hub dataset (chat messages or a prompt column), applies a model chat template, generates responses with vLLM, and pushes the output dataset + dataset card back to the Hub.
Requires: GPU + write token (it pushes a dataset).
from pathlib import Path
script = Path("hf-jobs/scripts/generate-responses.py").read_text() hf_jobs("uv", { "script": script, "script_args": [ "username/input-dataset", "username/output-dataset", "--messages-column", "messages", "--model-id", "Qwen/Qwen3-30B-A3B-Instruct-2507", "--temperature", "0.7", "--top-p", "0.8", "--max-tokens", "2048", ], "flavor": "a10g-large", "timeout": "4h", "secrets": {"HF_TOKEN": "$HF_TOKEN"}, })
Pattern 2: CoT Self-Instruct Synthetic Data — scripts/cot-self-instruct.py
What it does: generates synthetic prompts/answers via CoT Self-Instruct, optionally filters outputs (answer-consistency / RIP), then pushes the generated dataset + dataset card to the Hub.
Requires: GPU + write token (it pushes a dataset).
from pathlib import Path
script = Path("hf-jobs/scripts/cot-self-instruct.py").read_text() hf_jobs("uv", { "script": script, "script_args": [ "--seed-dataset", "davanstrien/s1k-reasoning", "--output-dataset", "username/synthetic-math", "--task-type", "reasoning", "--num-samples", "5000", "--filter-method", "answer-consistency", ], "flavor": "l4x4", "timeout": "8h", "secrets": {"HF_TOKEN": "$HF_TOKEN"}, })
Pattern 3: Streaming Dataset Stats (Polars + HF Hub) — scripts/finepdfs-stats.py
What it does: scans parquet directly from Hub (no 300GB download), computes temporal stats, and (optionally) uploads results to a Hub dataset repo.
Requires: CPU is often enough; token needed only if you pass --output-repo (upload).
from pathlib import Path
script = Path("hf-jobs/scripts/finepdfs-stats.py").read_text() hf_jobs("uv", { "script": script, "script_args": [ "--limit", "10000", "--show-plan", "--output-repo", "username/finepdfs-temporal-stats", ], "flavor": "cpu-upgrade", "timeout": "2h", "env": {"HF_XET_HIGH_PERFORMANCE": "1"}, "secrets": {"HF_TOKEN": "$HF_TOKEN"}, })
Common Failure Modes Out of Memory (OOM)
Fix:
Reduce batch size or data chunk size Process data in smaller batches Upgrade hardware: cpu → t4 → a10g → a100 Job Timeout
Fix:
Check logs for actual runtime Increase timeout with buffer: "timeout": "3h" Optimize code for faster execution Process data in chunks Hub Push Failures
Fix:
Add to job: secrets={"HF_TOKEN": "$HF_TOKEN"} Verify token in script: assert "HF_TOKEN" in os.environ Check token permissions Verify repo exists or can be created Missing Dependencies
Fix: Add to PEP 723 header:
/// script
dependencies = ["package1", "package2>=1.0.0"]
///
Authentication Errors
Fix:
Check hf_whoami() works locally Verify secrets={"HF_TOKEN": "$HF_TOKEN"} in job config Re-login: hf auth login Check token has required permissions Troubleshooting
Common issues:
Job times out → Increase timeout, optimize code Results not saved → Check persistence method, verify HF_TOKEN Out of Memory → Reduce batch size, upgrade hardware Import errors → Add dependencies to PEP 723 header Authentication errors → Check token, verify secrets parameter

Key Takeaways
Submit scripts inline - The script parameter accepts Python code directly; no file saving required unless user requests
Jobs are asynchronous - Don't wait/poll; let user check when ready
Always set timeout - Default 30 min may be insufficient; set appropriate timeout
Always persist results - Environment is ephemeral; without persistence, all work is lost
Use tokens securely - Always use secrets={"HF_TOKEN": "$HF_TOKEN"} for Hub operations
Choose appropriate hardware - Start small, scale up based on needs (see hardware guide)
Use UV scripts - Default to hf_jobs("uv", {...}) with inline scripts for Python workloads
Handle authentication - Verify tokens are available before Hub operations
Monitor jobs - Provide job URLs and status check commands
Optimize costs - Choose right hardware, set appropriate timeouts
