Frequently asked questions
Azure AI Foundry FAQs
What is Azure AI Foundry?
Azure AI Foundry is Microsoft's unified AI platform combining Azure OpenAI Service and Azure AI Studio. It provides enterprise access to GPT-6, Claude 5, Llama 4, and 1,800+ models with private networking, Azure AD integration, and compliance certifications.
Does Azure AI Foundry support GPT-6?
Yes. Azure AI Foundry provides access to OpenAI's latest models including GPT-6 Astra and the GPT-5.6 series (Sol, Terra, Luna) under Azure enterprise SLAs with private networking.
How does Azure AI Foundry pricing compare to OpenAI directly?
Azure AI Foundry pricing for OpenAI models matches the direct OpenAI API pricing. The value add is enterprise features: private VNet, Azure AD, compliance certs, and a single Azure invoice — not a price discount.
Hugging Face FAQs
What is the Hugging Face Inference API?
The Hugging Face Serverless Inference API provides pay-per-request access to popular open-weight models including Llama 3.3 70B, Qwen 2.5 72B, and FLUX.1-dev. No infrastructure management required — just an API key.
How much does the Hugging Face API cost?
Serverless Inference API pricing varies by model. Llama 3.3 70B and Qwen 2.5 72B are $0.59/$0.79 per 1M input/output tokens. FLUX.1-dev is $0.025 per image. A free tier is available for low-volume use. See huggingface.co/pricing for current rates.
Can I use my own fine-tuned model on Hugging Face?
Yes. You can deploy your own fine-tuned model on Hugging Face Inference Endpoints (dedicated) or upload it to the Hub for Serverless Inference if it meets the supported architecture requirements.
