AI API Free Tiers are provider programs that give you limited no-cost access to AI models through an API. That can mean a one-time signup credit, a monthly credit allowance, free tokens, or a rate-limited tier that keeps working after your promo credit runs out. They’re designed for testing and small-scale usage: building a proof of concept, benchmarking models, validating latency, or wiring up a new feature before you put a card on file. Terms vary by provider, and credits may expire or be restricted to specific products or plans.

This category includes programs from Anthropic, OpenAI, xAI, Groq, Hugging Face, Mistral AI, Replicate, IBM, SambaNova, DeepSeek, Fireworks AI, GitHub, Cloudflare, Cohere, Alibaba Cloud, Cerebras, Novita AI, Perplexity, and more. Each provider sets its own credit amounts, limits, and eligibility rules.

Yes, where program terms allow. AI Credit Mart is a marketplace to buy and sell unused AI credits, so you can reduce waste or top up quickly. Always verify expiry dates, transfer rules, and whether the credits are tied to a specific account or plan before listing or purchasing.

Recurring credits are typically granted each month and can reset on a billing cycle, but they often come with conditions. For example, some offers require opting into data sharing, keeping an account in good standing, or staying on a specific plan. Unused portions may not roll over, and usage beyond the allowance is billed at standard rates. Before you rely on recurring credits for production, confirm the renewal timing, what happens after the allowance is consumed, and whether the provider can change or revoke the offer.
