AI API Router Directory

Azure OpenAI (Microsoft Foundry) serves the GPT family per 1M tokens in three priced deployment scopes — Global, Data Zone (EU/US, +10%) and Regional (up to 27 regions): GPT-5.6 Sol $5/$30 (short context, Global), Terra $2/$12, Luna $0.20/$1.20, gpt-oss-120b $0.15/$0.60. Batch (−50%) and PTU reservations (from $1/PTU/hr Global) sit under the same account; new Azure accounts carry a $200/30-day trial credit.

New Azure accounts: $200 credit for 30 days (stated on the Azure OpenAI pricing page; Azure-wide, applicable to Azure OpenAI — verified 2026-09-16). No standing free tier beyond it.

ChatAnywhere is a widely used free LLM relay. Users bind a GitHub account to get a free API key and access GPT-4o, Claude, and Gemini models through an OpenAI-compatible interface, optimized for access from mainland China.

GitHub-bound free key: 10,000 points/day with per-model caps (GPT-5/4o/4.1 5/day, DeepSeek 30/day, mini models 100/day, ~200 req/day total) ≈ $2/mo; personal non-commercial use only.

Free.ai is an AI tool aggregator offering 477+ tools across chat, image, and video. It provides 30,000 free tokens daily for registered users and supports premium models like GPT-6 and Claude via paid plans. The platform features an in-browser IDE for deploying AI applications.

No public free-tier information found in the source reference; treat free-tier availability as unverified rather than confirmed absent.

GitHub Models was GitHub's hosted model playground, model catalog, inference API and bring-your-own-key service, and GitHub previously presented it as separate from GitHub Copilot. GitHub's official documentation now states that as of July 30, 2026, GitHub Models has been fully retired: the playground, model catalog, inference API and BYOK are no longer available to any customer. The same page directs users needing model access to Azure AI Foundry and users wanting AI workflows on GitHub to GitHub Copilot.

No free tier stated on official pages; GitHub Models was fully retired on July 30, 2026 with no playground, catalog, inference API or BYOK access remaining (checked 2026-09-16).

OpenAI's API is per-token with no free tier: GPT-6 Astra $10/$50, GPT-5.6 Sol $4/$20 (promo through Nov 21, 2026), Terra $2/$12 and Luna $0.20/$1.20 per 1M in/out for standard context (<272K), with Batch at 50% off, cached-input pricing, and a +10% data-residency toggle. Images (GPT-Image-2.5) and voice (GPT-Live-1) carry separate token rates.

No free tier on the API (checked 2026-09-16). The consumer ChatGPT free plan is a separate product, not API access.
