What this is
A cautious access directory
AI Access tracks free and low-cost ways to test LLM APIs, model gateways, and inference credits without treating free access as guaranteed production capacity.
Theme
AI Access
Free LLM APIs and model testing credits.
A practical directory of free and low-cost ways to try LLM APIs, model gateways, and inference credits.
This page is a general reference, not a recommendation. Free tiers, limits, model availability, and provider terms can change, so always check the original provider before relying on any service.
How to use it
Start small, check terms
Use the cards to compare access type, best fit, caveats, and source links before testing a provider.
Important caveat
Free does not mean unlimited
Free quotas, model access, rate limits, privacy terms, and trial credits can change. Avoid sensitive data unless you have reviewed the provider terms.
Before relying on access
Check before relying on free access
Free tiers, trial credits, model availability, rate limits, and provider terms can change. AI Access is a general reference for discovery, not a recommendation or guarantee. Avoid sending sensitive, private, or confidential data to free or unpaid tiers unless you have reviewed the provider's current terms.

Learning, small experiments, model comparison, and early prototypes.
Free access note
OpenRouter describes openrouter/free as a router that sends requests to currently available free models, and also supports :free variants for specific models where a free variant exists.
Limits note
Source snapshot, May 2026: OpenRouter docs described free-model limits such as 50 requests per day for accounts that have purchased less than 10 credits, 20 requests per minute, and 1000 free-model requests per day after purchasing at least 10 credits. Check OpenRouter directly before relying on this.
Caution
Free model access can have lower limits, changing availability, provider-side throttling, and temporary unavailability. Do not treat free access as production capacity.
Privacy note
Avoid sensitive, private, or confidential data unless you have reviewed OpenRouter's current terms, data-policy details, and account settings.
