VSLLM (Weiyun Model Open Platform) is a commercial AI API relay gateway that aggregates multiple large models. It is OpenAI-compatible and features a daily auto-refreshing free quota for new sign-ups. Claims to offer highly competitive, transparent pricing based on actual token usage.

Free subscription auto-refreshes daily without claiming: ~20 API calls + ~100K tokens/day (non-cumulative, reset next day) ~ $3/mo at $1/1M tokens; also GitHub-star and daily check-in reward activities.

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.

ChatAnywhere (GPT_API_free) is a widely used AI API relay providing unified access to global models including OpenAI, Claude, Gemini, and DeepSeek. It offers a GitHub-authorized free tier and low-cost paid access with endpoints optimized for users in mainland China and overseas.

Free keys, personal non-commercial only: ~200 req/day per IP&key (GPT-5/4o/4.1 5/day, DeepSeek 30/day, small models 200/day) ≈ $2/mo equivalent at typical token volumes.

DuiAPI is a Chinese commercial-aggregator relay emphasizing compliant, ICP-registered access to official AI platforms. It supports Qwen, DeepSeek, and Kimi models through OpenAI and Anthropic compatible endpoints.

$2 signup trial credit reported.

Nodeloc partner post (2026-08-19): Nodeloc users get $2 signup credit plus weekly lottery and first-top-up promos; e7ai post mentions a claimable $50 subscription voucher. Core remains a paid top-up relay.

Unity2.Ai is a commercial AI infrastructure provider offering seamless access to top Chinese and global AI models (Claude, GPT, Gemini, DeepSeek) via a single OpenAI-compatible API. Features self-developed cluster architecture for high concurrency and smart upstream scheduling. Supports Alipay and WeChat via Stripe.

$2 sign-up credit; Linux.do/V2EX campaign activity (replies, votes, per-100-floors) can add $10-$100 (promotional, unverified terms). Core is pay-as-you-go; no long-term free flagship quota.

OpenRouter is a unified, OpenAI-compatible API aggregating hundreds of model providers behind one key. Free model variants (:free IDs) are genuinely free with documented platform caps — 20 requests/min and 50/day for accounts that have purchased under 10 credits, 1,000/day once you've purchased 10+ — while paid variants have no platform request cap. Fallback routing, per-key credit caps, and BYOK are built in.

:free models cost $0, no card; 20 req/min; 50 :free req/day with <10 credits, 1000/day after buying $10+ credits (verified FAQ; failed reqs count). ~$1.5/mo equivalent at 50 req/day, ~1K tokens/call.

Agnes AI, developed by Singapore-based Sapiens AI, is an omni-modal AI platform offering indefinitely free access to core text, image, and video models. It supports OpenAI-compatible API keys and tiered 'Token Plans' for production-level throughput.

Advertised as indefinitely free core-model API with rate/volume caps; signup probe hints ~$1 starter credit (counted). Free tier reportedly sufficient for individual developers and demos.

JuCodex is a Chinese-market AI relay specializing in coding models, reselling access to OpenAI's Codex and GPT-4 variants. It features a custom ratio system for billing and provides a small initial credit for new accounts to test compatibility with IDE extensions.

One-off new-user credit: 6 RMB (≈$0.89) on signup (QQ-email only), ratios as low as 0.15; only 1 free entry in /api/pricing, no sustained free quota, essentially pay-as-you-go.

DeepSeek's official API serves the current V4.1-Flash and V4-Pro models with 1M-token context and 384K max output, from $0.15/$0.60 per 1M in/out off-peak (Flash) — peak hours bill at 2x, cached input drops to $0.003/M. One key exposes both an OpenAI-compatible and an Anthropic-compatible endpoint, and sign-up grants a free token balance that is deducted before any top-up.

Free 'granted balance' of ~5M tokens at sign-up (deducted before top-ups per official billing rules); $0.70 is an estimate at V4-Flash off-peak rates.

Aion Labs provides specialized fine-tuned models for immersive roleplay and storytelling. Its API is OpenAI-compatible and features a long-term daily free allowance for developers, with higher tiers available upon account top-up.

Daily allowance of ~20K tokens equates to ~$0.50/mo in nominal value.

NexoToken is a commercial aggregation relay covering 130+ LLMs with an OpenAI-compatible /v1 endpoint. It uses an ultra-low-multiplier (0.01x-0.03x) billing system and offers a daily refreshing free quota for ~40 models.

~40 models offer daily free quotas that auto-refresh the next day (including some Claude/GPT/Gemini models); claims of sign-up bonus and 7-day no-questions refund are platform self-promotion — actual amounts per the console.

BazaarLink is a Taiwan-based AI aggregator providing access to 100+ models via an OpenAI-compatible API. It specializes in TWD billing and unified enterprise invoices. It offers a small signup credit and a persistent free model tier.

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.

ProRiseHub is a paid top-up relay built on the New API framework, OpenAI-compatible at /v1. Documentation states top-ups are converted at a rate of 1 RMB ≈ $0.15 USD credit, with several dozen zero-priced models.

Mainly paid top-up (1 RMB (≈$0.15) = 1 USD credit); no general signup bonus mentioned; ~51 zero-priced models in /api/pricing.

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.

OpenAI Codex is the coding agent that runs across ChatGPT, an IDE extension, the CLI and cloud environments on a single ChatGPT account, with cloud worktrees, scheduled background tasks, Skills and code review. The Codex pricing documentation lists Free at $0/month for "quick coding tasks", Go at $8/month, Plus at $20/month, Pro from $100/month, Business at $20/user/month billed annually ($25 monthly, minimum 2 users) and Enterprise/Edu by contact, plus an API-key route billed at API rates. Usage is measured as messages per five-hour period that vary by model: on Plus, the documented ranges run from 250-2,000 messages for GPT-5.6 Luna down to 5-45 for GPT-6 Astra, and OpenAI states these are estimates rather than fixed limits.

Codex Free is $0/month, described as "Explore Codex capabilities on quick coding tasks"; no fixed free message count is published (Codex pricing docs, checked 2026-09-16).
