Measured results are shown as published

Every score in the benchmark tables comes from its source unchanged. Composite IQ averages all seven dimensions equally.

Estimates fill the gaps

Abstract Reasoning, Mathematical Reasoning and Computer Use have no published results yet, so their IQ is estimated from mercury-2's other dimensions.

A missing result is not a zero

Benchmark versions and evaluation harnesses can differ between sources, so small gaps between models may not be meaningful.

How AI IQ scores models →Get this data from the API →
What is the IQ of mercury-2?
mercury-2 has an estimated IQ of 93, which ranks #156 out of 176 public models on the AI IQ leaderboard. The score combines seven equally weighted reasoning dimensions using measured benchmark results and conservative estimates for missing coverage.
What is mercury-2 best at?
Among the dimensions with published benchmark results, mercury-2 ranks highest in Academic Reasoning (IQ 111, #135 of 203) and Knowledge Work (IQ 98, #123 of 176). Its lowest-ranked measured dimension is Reliability (IQ 102, #139 of 177).
What is the EQ of mercury-2?
mercury-2 doesn't have an EQ score yet. EQ (emotional reasoning) is calculated from EQ-Bench 4 and AttuneBench, and neither has published a result for mercury-2. AI IQ doesn't estimate EQ from other benchmarks, so the score appears once one of those results is published.
Which benchmarks has mercury-2 been tested on?
mercury-2 has published results on 12 of the 39 benchmarks behind AI IQ's Composite IQ, including IFBench, Humanity's Last Exam, CritPt, GPQA Diamond and SciCode.
How much does mercury-2 cost?
mercury-2 costs $0.25 per million input tokens and $0.75 per million output tokens. Adjusted for how many tokens it actually consumes on real tasks, its effective cost works out to $0.631 per million input-plus-output tokens.
Is mercury-2 open source?
No — mercury-2 is a proprietary model. Its weights are not publicly available, so it is used through hosted APIs and products.
Who developed mercury-2?
mercury-2 was developed by Inception, based in the United States.
When was mercury-2 released?
mercury-2 was publicly released on February 24, 2026.
How large is the context window of mercury-2?
mercury-2 supports a context window of 128,000 tokens — the amount of text it can consider in a single request.
How fast is mercury-2?
In independent measurements, mercury-2 generates about 508 tokens per second, with a typical response time of about 8.1 seconds.
