Transformers Library

`pipeline()` for quick inference. `AutoModel` for loading any model. Tokenizers, trainers, quantization tools. Integrates with PyTorch, TensorFlow, JAX. Production-ready inference optimization.

Inference API & Endpoints

Serverless Inference API: Pay per request, no infrastructure management, instant deployment. Inference Endpoints: Dedicated instances with autoscaling, custom hardware (GPUs), private deployment. Deploy in minutes.

AutoTrain (Fine-Tuning)

No-code fine-tuning interface. Upload dataset, select model, configure hyperparameters, train. Or use Transformers library for custom training loops. LoRA/QLoRA for efficient fine-tuning.

Good fit when: - Want model choice and flexibility - Need to fine-tune on proprietary data - Open-source preference (license, control, community) - Cost-sensitive (self-hosting for high volume) - Building ML research or experimentation workflows

Consider alternatives when: - Need absolute latest proprietary models (GPT-4, Claude Opus) - Prefer managed simplicity (OpenAI, Anthropic simpler) - No ML expertise to manage models and infrastructure - Enterprise support and SLAs critical (HF Enterprise available but less mature)

Self-Hosted Open Models

Download Llama 3 70B, Mistral 7B, or other models from Hub. Deploy on your infrastructure (AWS, GCP, on-premise). Full control, no API fees. We handle deployment and optimization.

Fine-Tuning on Your Data

Fine-tune Llama, Mistral, or domain-specific models on your data. Use LoRA for efficient training. Deploy fine-tuned model via Inference Endpoints or self-hosted. Keep weights private.

Embeddings & Retrieval

Use SentenceTransformers (BGE, E5 models) for embeddings. Often better and cheaper than proprietary embeddings. Self-host for unlimited usage at fixed infrastructure cost.

Vision & Multimodal

CLIP for image search, SAM for segmentation, BLIP for image captioning, LLaVA for vision-language. Deploy on GPUs for production vision pipelines.

Rapid Experimentation

Try 10 models in a day via Inference API. Test which performs best for your use case. Switch from Mistral to Llama to Falcon with code change. Pick winner, then optimize deployment.

Serverless Inference API

Pricing: Pay per request (~$1 per 1M tokens for 7B models)

Pros: No infrastructure, instant deployment, auto-scaling

Cons: Higher cost at volume, rate limits, shared infrastructure

Use When: Low-medium volume, testing, prototyping

Inference Endpoints (Dedicated)

Pricing: £300-2k/month for dedicated GPU instances

Pros: Predictable costs, no rate limits, private deployment, autoscaling

Cons: More expensive than self-hosted at very high volume

Use When: Production, need reliability and control

Self-Hosted (Your Infrastructure)

Pricing: GPU infrastructure costs (£500-3k/month, unlimited usage)

Pros: Lowest cost at high volume, full control, data privacy

Cons: Need DevOps expertise, manage infrastructure

Use When: High volume, data sovereignty, cost optimization

vs OpenAI/Anthropic: - HF: Open models, fine-tuning freedom, cost control at scale, model choice - OpenAI/Anthropic: Latest proprietary models, simpler managed service, less setup

vs Replicate/Together AI: - HF: Largest model selection, Transformers library integration, more control - Replicate/Together: Simpler API, curated models, faster deployment

vs Self-Managed from Scratch: - HF: Pre-built infrastructure (Inference Endpoints), model hub, community support - Self-managed: Complete control but more work (no model hub, build everything)

How does Hugging Face compare to OpenAI?

OpenAI: GPT-4/GPT-3.5 (proprietary, leading edge), simple API, no fine-tuning access to latest. Hugging Face: 500k+ open models (Llama, Mistral, etc.), full fine-tuning, self-host option, lower cost at scale. Choose OpenAI for latest capabilities, HF for flexibility and cost control.

Can we fine-tune models on Hugging Face?

Yes. Use AutoTrain (no-code) or Transformers library (custom training). Fine-tune Llama, Mistral, domain models on your data. LoRA/QLoRA for efficient training. Keep model weights private. Deploy via Inference Endpoints or self-hosted.

What does Hugging Face cost?

Models: Free (download and self-host). Serverless Inference API: ~$1 per 1M tokens for 7B models. Inference Endpoints: £300-2k/month for dedicated GPUs. AutoTrain fine-tuning: £50-500 depending on model size and data. Self-hosting: infrastructure costs only.

Can we self-host Hugging Face models?

Yes. Download any open-weight model from Hub. Deploy on your infrastructure using Transformers library, TGI (Text Generation Inference), vLLM, or Ollama. Complete control, no API fees. We help with deployment and optimization.

What models are available on Hugging Face?

500k+ models: Llama 2/3, Mistral, Phi, Falcon, BERT, GPT-2, T5, Whisper (audio), CLIP (vision), SentenceTransformers (embeddings), and thousands more. Filter by task, license, size, language. Try via model cards before downloading.

How long to deploy with Hugging Face?

Serverless Inference API: Immediate (minutes). Inference Endpoints: 1-2 weeks for production setup. Self-hosted: 3-4 weeks (infrastructure + optimization). Fine-tuning: Add 2-4 weeks for training and validation.

Do Hugging Face models match GPT-4 quality?

Llama 3 405B: Competitive with GPT-4 on many benchmarks. Llama 3 70B / Mistral: Similar to GPT-3.5 Turbo. 7B-13B models: Less capable but faster and cheaper. Quality-cost-latency tradeoff. Choose based on your requirements and budget.

1. Model Selection & Testing (1-2 weeks) Identify use case, test candidate models via Inference API (Llama, Mistral, domain models). Compare accuracy, latency, cost. Select best fit.

2. Fine-Tuning (Optional) (3-4 weeks) If needed, fine-tune selected model on your data using AutoTrain or custom training. Test fine-tuned model accuracy vs base model.

3. Production Deployment (2-4 weeks) Deploy via Inference Endpoints (managed) or self-hosted (your infrastructure). Integrate with applications, add monitoring, optimize for production load.
