Frequently Asked Questions
What is the cheapest AI model API?
The table at the top of this page ranks A2Agent’s models by live price, input and output weighted 3:1. Flash tiers such as DeepSeek V4 Flash, GLM-5.3 Flash and the Qwen Flash models usually lead it. Every model is billed per token, with no subscription required.
What is the cheapest LLM for coding?
Open the Models page and filter by Coding. The model marked Cheapest for coding is the lowest-priced coding model in the catalog. For agentic work in Claude Code or Codex CLI, test a few candidates on your own repository.
Is there a free AI API key?
No. A2Agent has no free tier. You pay as you go, and top-up bonuses, when offered, are listed on the pricing page. Bonus credits cannot be refunded.
How does A2Agent compare to OpenRouter?
OpenRouter lists 500+ models from many providers and passes provider prices through. It charges a 5.5% fee ($0.80 minimum) when you buy credits by card, and unused credits may expire after 365 days (OpenRouter FAQ and terms, checked September 28, 2026). A2Agent focuses on DeepSeek, GLM, Kimi, Qwen and MiniMax, prices them below the vendors’ official list prices, and credits do not expire while your account is active.
Are these the official models?
Yes. A2Agent sources every model directly from the vendor’s official platform, and each model ID names the release it serves, such as deepseek-v4-flash or glm-5.3. A2Agent is a gateway: it does not train or modify models.
