AI API Router Directory

Nscale's Serverless Inference is an OpenAI-compatible endpoint service for open models - the catalogue pages list Meta Llama 4 Scout, Alibaba Qwen, DeepSeek, OpenAI GPT OSS 20B/120B, Mistral 8x22B Instruct, FLUX.1 [schnell] and Stable Diffusion XL Base 1.0 - with token-based pay-as-you-go billing. Per Nscale's own launch materials, pricing is based on input and output tokens for text and vision models, while image generation is priced on output image dimensions. Per-token rates are not published on a static official page: the docs direct users to the console's AI Services to Models list or the /v1/models API endpoint for pricing and context length. Every new user can claim $5 of free credit, and Nscale states the platform does not log or train on request or response content.

Every new user can claim $5 of free credit, stated in Nscale's Serverless Inference launch post (2 April 2025) and in its announcement that pricing is based on input and output tokens for text and vision models.

Fireworks AI is a self-serve inference platform: per-token serverless (Standard/Priority/Fast tiers) with $1 in free credits and postpaid billing, fine-tuning (LoRA and full-param, priced per 1M training tokens), a shared-pool Serverless Training API, and on-demand GPUs from $8/hr (H100, from Sep 1 2026) to $20/hr (GB300).

Official pricing page: 'Get started with $1 in free credits' (confirmed 2026-09-16).

Cloudflare Workers AI serves open-weight models on Cloudflare's edge network, metered in Neurons ($0.011 per 1,000). Every account — including the Free plan — gets 10,000 Neurons per day free, resetting at 00:00 UTC; beyond that, the Paid plan bills usage. The catalog spans LLMs, embeddings, image and audio models and sits next to your Workers apps.

10,000 Neurons/day free on all plans (reset 00:00 UTC) ≈ $0.11/day ≈ $3.30/month at full use; overage $0.011 per 1,000 Neurons on the Paid plan.

Hugging Face Inference Providers routes one API key across 200+ models from multiple inference providers at the providers' own rates — no markup. Every user gets monthly credits ($0.10 on the Free plan; $2.00 PRO; $2.00/seat Team & Enterprise) applied automatically before pay-as-you-go; a BYOK mode routes through your own provider keys instead.

Official docs: $0.10/month Inference-Providers credits for Free users (PRO $2.00/month, Team/Enterprise $2.00/seat), credited monthly and applied before pay-as-you-go (confirmed 2026-09-16).

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).

Novita AI runs 200+ models across text, image, audio and video behind an OpenAI-compatible API at api.novita.ai/openai, plus serverless endpoints, GPU instances and agent sandboxes, all billed per token or per GPU-second. Published model rates start at $0.02/1M input and $0.05/1M output for Llama 3.1 8B Instruct, with DeepSeek V4 Flash at $0.14/$0.28 on a 1M-token context, and three Ling 3.0 Flash variants (Fin, VL, Sante) listed at Free input and Free output with 256K context. Batch inference carries an introductory 50% discount on input and output tokens for supported models.

No standing free credit is stated on the current official pricing or docs pages (checked 2026-09-16); the pricing table lists Ling 3.0 Flash Fin/VL/Sante at Free input and output (256K context), and an official blog post from May 2025 advertised a limited-time $10 new-user credit that current pages do not repeat.
