Aion 3.5 is a language model developed by Zhipu AI. It's particularly well-suited for tackling complex, multi-step reasoning problems, orchestrating tool-using agents that call APIs and external services, grounding responses in real-time web search results, producing structured outputs for reliable data extraction and handling large contexts of up to 262K tokens. Its 262K-token context window means you can pass in entire documents, codebases, or conversation histories without losing context. It can write up to 33K tokens in a single response.
As of Oct 26, 2026, Aion 3.5 costs $5.06 per 1M input tokens and $10.13 per 1M output tokens on Qubax. A typical 1,000 chat requests (2K tokens in, 500 out) come to about $15.19. 3 independent compute providers currently serve it, so requests fail over automatically. Pay with USDC, USDT, BTC, ETH or 350+ other coins — no credit card required.
