The Gemini API free tier is available to developers in the EU, UK, and Switzerland; the available regions page lists these regions. The terms still require you to use only Paid Services when you make an API Client available to users in the European Economic Area, Switzerland, or the UK. Google no longer publishes per-model free-tier rate limits; check your quotas in AI Studio. Free-tier prompts may be used by Google to improve products, except for users in the EEA, Switzerland and the UK, where the paid-services data terms also govern the unpaid quota, so those prompts are not used to improve Google products. gemini-3.1-flash-lite is on the deprecation schedule, with a shutdown date of May 7, 2027 and gemini-3.5-flash-lite as its replacement; the row stays because the model is live and free today. ↩︎

Mistral plans are global: the monthly allowance is shared across Studio, the API, and Vibe Code, so CLI usage eats the same budget (subscriptions). Free mode is the default for new accounts and needs no credit card (quickstart), and the Free plan card on the pricing page is what carries the $10/month in API credits figure quoted in the description. Free-mode inputs and outputs may be used to train Mistral models, and you can opt out at any time (data usage). Mistral no longer publishes numeric free-tier rate limits and points you at the Limits page of the admin panel instead (rate limits); the rate limit column is kept from the last published values. ↩︎

Registration accepts overseas phone numbers (registration FAQ) and the chat API does not require real-name verification: 目前调用 API 并不强制要求实名认证 (authentication FAQ). The Batch API does require it (batch FAQ). The same free models are served from the international platform at https://api.z.ai/api/paas/v4 (endpoint), where GLM-4.7-Flash, GLM-4.5-Flash and GLM-4.6V-Flash are all priced Free (pricing). Z AI has announced that GLM-4.5-Flash will be retired and its requests auto-routed to GLM-4.7-Flash (model page); the announced date has already passed while the model is still catalogued and still priced Free, so treat that row as living on borrowed time. ↩︎

The 10,000 free Neurons are shared across all Workers AI usage, not per model, and all limits reset daily at 00:00 UTC. Going over does not bill you, the request fails. Five models are excluded from Workers Free billing and need the Workers Paid plan or prepaid AI Gateway credits: @cf/moonshotai/kimi-k2.6, @cf/moonshotai/kimi-k2.7-code, @cf/zai-org/glm-5.2, @cf/deepseek-ai/deepseek-v4-flash-0731, @cf/deepseek-ai/deepseek-v4-pro-0813 (pricing). ↩︎

Groq shut down llama-3.3-70b-versatile and llama-3.1-8b-instant on August 16, 2026 (deprecations). Remaining free-plan limits vary by model: compound and compound-mini get 250 RPD, most others 1,000 RPD (rate limits). ↩︎

Kilo Code's free pool changes frequently, and the /api/gateway/models catalog can lag what is actually served: probe results have confirmed models absent from the catalog still answering. Every row listed here answered a live request between 2026-08-19 and 2026-08-21. Free models are reachable with no API key, at 200 requests per hour per IP (authentication). The kilo-auto/free router picks a model from the free pool, and Kilo's docs warn it "may route your requests to providers that log prompts and outputs". The NVIDIA free endpoints carry NVIDIA's own condition, quoted on Kilo's models page: "Trial use only - do not submit personal or confidential data. Your use is logged for security purposes and to improve NVIDIA products and services." ↩︎

LLM7.io rotates its catalog frequently, so the model list changes between checks. Access is tier-based, not token-based: turbo models are reachable anonymously or with a free token, pro models need the paid plan (models API). Anonymous access is capped at 1 RPS, 10 RPM, 60 requests per hour and 500,000 tokens per 24 hours; a free token raises that to 2 RPS, 40 RPM, 100 requests per hour and 1,000,000 tokens per 24 hours (limits). A paid Pro plan is available at $12/month. Anonymous access with no key was confirmed by live request on 2026-08-21. ↩︎

API-Inference is free for registered users. Current published limits are 2,000 requests/day per user (total across models), with per-model daily quotas dynamically adjusted and capped at 500; concurrency is also dynamically rate-limited. Requires Alibaba Cloud account binding and real-name verification (limits, intro). ↩︎

Ollama Cloud measures usage by input, cached input, and output tokens weighted per model (FAQ). Free tier has session limits resetting every 5 hours and weekly limits resetting every 7 days. Cloud models are also served through Ollama's OpenAI-compatible endpoint at ollama.com/v1. ↩︎

Free models default to 50 RPD per model. A one-time purchase of $10+ in credits unlocks 1,000 RPD for free models. OpenRouter also offers a Free Models Router (openrouter/free) and model fallbacks for chaining models in priority order. Free providers may log prompts for training. ↩︎

OVHcloud AI Endpoints offers a permanent free anonymous tier (2 requests per minute per IP, per model) with no signup or API key required. Higher rate limits (400 RPM per Public Cloud project per model) require an API key and are billed pay-as-you-go per token; new Public Cloud accounts get up to $200 in free trial credits. Models are hosted in EU data centers. ↩︎

SiliconFlow requires real-name identity verification to use free models (effective May 15, 2026, per the release notes). Verification supports mainland-Chinese documents; international users must contact support. ↩︎
