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

Hyperbolic (hyperbolic.xyz) is the API-specific endpoint for Hyperbolic's AI cloud. It provides serverless inference for over 25 open-source models through an OpenAI-compatible /v1 endpoint. The platform supports text, image, and audio generation with pay-as-you-go pricing.

~$1 trial credit for new users (DeepSeek V3, Llama 3.1 405B, Qwen); pay-as-you-go after it is used (Llama 405B ~$4/M, DeepSeek R1 ~$3/M tokens).

Nebius AI Studio is a European-based GPU cloud platform providing managed inference for top open-source LLMs like Llama 3.1 and DeepSeek R1. It leverages its own EU data centers to offer high-performance, privacy-compliant inference with transparent pay-as-you-go pricing tailored for both developers and enterprises.

AI Studio grants new accounts ~$1 one-time trial credit (startup/promo programs can grant far more); Nebius AI Cloud free-trial program suspended as of 2026-07-13; studio models otherwise pay-as-you-go.

Scaleway Generative APIs is a serverless, OpenAI-compatible inference service hosted only in Paris and billed per 1M tokens in euros. Published rates run from EUR 0.15/1M input and EUR 0.60/1M output for gpt-oss-120b, and EUR 0.15/EUR 0.35 for mistral-small-3.2-24b-instruct, up to EUR 1.80/EUR 5.50 for glm-5.2; whisper-large-v3 is metered per audio minute at EUR 0.003 with free output tokens, and embedding models are input-only at EUR 0.10/1M. Every new customer gets a free tier of 1,000,000 tokens, with billing starting at token 1,000,001.

1,000,000 free tokens per new customer, stated on the Generative APIs page; valued at the cheapest published input rate of EUR 0.15/1M (mistral-small-3.2-24b-instruct or gpt-oss-120b), which is roughly USD 0.16 - the grant is token-denominated, so actual dollar value varies by model.

The Cloudflare AI Playground at playground.ai.cloudflare.com is a browser environment for experimenting with, benchmarking and tuning AI models, with a Model mode for testing system prompts and run settings, a Compare mode for side-by-side evaluation of models under identical prompts, and an experimental Generative UI mode. It is the front end for models that Cloudflare hosts and serves, and the free access terms come from Workers AI: the free allocation allows anyone to use a total of 10,000 Neurons per day at no charge, with additional usage on the Workers Paid plan billed at $0.011 per 1,000 Neurons. The model catalog covers 65 models including Llama, Qwen, DeepSeek, Kimi, GLM, Gemma, Mistral, Nemotron, Whisper and FLUX families, and the playground itself states that output is unverified and does not reflect Cloudflare's views.

Free allocation is stated as 10,000 Neurons per day at no charge on the Workers AI pricing page, equivalent to about $0.11/day at the published rate of $0.011 per 1,000 Neurons (the dollar figure is a conversion, the allowance is official).

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.

Nomic AI provides the Atlas Embedding API and open-weight models like nomic-embed. It offers a monthly free tier for its embedding API and is transitioning to focus on document AI for specialized industries.

Atlas embedding API free tier ~1M embedding tokens/month for evaluation and prototyping; ~$0.10/mo equivalent at Nomic embed pricing (~$0.10/1M tokens); paid beyond that.

SambaNova Cloud serves open-weight models (DeepSeek-V3.1, DeepSeek-V3.2, Meta-Llama-3.3-70B-Instruct, gpt-oss-120b, gemma-4-31B-it, MiniMax-M2.7 and MiniMax-M3) through an OpenAI-compatible endpoint at api.sambanova.ai/v1, priced per 1M tokens from $0.22 input / $0.59 output for gpt-oss-120b up to $3 / $4.50 for DeepSeek-V3.1 and V3.2. The free tier is defined by the absence of a payment method: 20 requests per minute, 20 requests per day and 200,000 tokens per day per model, on the five models listed in the free-tier tables. Linking a card moves the account to the Developer tier, which raises per-model limits and caps the account at 20M tokens per day across all models.

Free tier is a recurring daily allowance, not a USD credit: 200,000 tokens/day (20 RPM, 20 RPD) per the official rate-limits docs; 200k tokens at the cheapest published input rate of $0.22/1M (gpt-oss-120b) is about $0.04/day, while the same 200k at DeepSeek-V3.1's $3/1M input rate would be about $0.60/day.

Alibaba Cloud Model Studio (Bailian, 百炼) is Alibaba Cloud's managed model platform, hosting Qwen and third-party models across text, image, audio and video with pay-as-you-go billing per million tokens in CNY. The cn-beijing list rates on the official price page include qwen-long at 0.5 CNY per million input tokens and 2 CNY per million output tokens, qwq-plus at 1.6 CNY input and 4 CNY output, and deepseek-v3.2-exp at 2 CNY input and 3 CNY output, while international-deployment rates are materially higher (qwq-plus international: 5.871 CNY input, 17.614 CNY output). The price page states it shows list prices only ('原价') and that promotional pricing lives in the console, and pricing is tiered so a single request's token volume sets the unit price for that whole request.

Token allowance, not cash: first activation of Bailian grants a per-model free inference quota of typically 1,000,000 tokens (input and output combined, cn-beijing only, valid 90 days) per help.aliyun.com/zh/model-studio/new-free-quota; no USD-convertible value is published (checked 2026-09-16).

Baseten offers Model APIs, hosted open-weight models behind an OpenAI Chat Completions endpoint at inference.baseten.co with a beta Anthropic Messages endpoint, alongside dedicated GPU deployments and training billed per minute. Model API rates range from $0.10/1M input and $0.50/1M output for GPT OSS 120B to $3.00/1M input and $15.00/1M output for Kimi K3, with cached input billed at roughly a tenth of the input rate. The Basic plan is $0 per month pay-as-you-go, and the pricing FAQ states new accounts come with credits but publishes no amount.

The official pricing FAQ states that new Baseten accounts come with credits to experiment with deployments, but no dollar amount, expiry or conditions are published (checked 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.
