Providers that let you call a large language model without paying. Some are free forever, some hand out signup credits, and some are limited-time offers — rated 0-5 on quota, rate limits and stability to help you pick quickly.
Free tiers usually come with strict limits. They are best suited to development, prototyping and testing — we do not recommend relying on them in production.
Quota, rate limit and stability ratings are subjective assessments by the site editors based on hands-on testing. They are indicative only — always check the provider's own documentation for the actual terms.
