About Mercury 2

Mercury 2 is a language model developed by Other. It's particularly well-suited for tackling complex, multi-step reasoning problems, orchestrating tool-using agents that call APIs and external services, producing structured outputs for reliable data extraction and handling large contexts of up to 128K tokens. Its 128K-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 Nov 4, 2026, Mercury 2 costs $0.297 per 1M input tokens and $0.890 per 1M output tokens on Qubax. A typical 1,000 chat requests (2K tokens in, 500 out) come to about $1.04. 6 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.
