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, Academic Reasoning, Programmatic Reasoning, Computer Use, Reliability and Knowledge Work have no published results yet, so their IQ is estimated from Mercury 3's other dimensions. Missing benchmarks can also draw on its predecessor, Mercury 2.5; a predecessor is an estimation input, not evidence that this model has the predecessor's measured results.

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 3?
Mercury 3 has an estimated IQ of 98, which ranks #135 out of 173 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 3 best at?
There isn't any published benchmark data to judge that yet. None of the seven dimensions AI IQ scores has a measured result for Mercury 3, so its strengths and weaknesses can't be compared with other models.
What is the EQ of Mercury 3?
Mercury 3 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 3. AI IQ doesn't estimate EQ from other benchmarks, so the score appears once one of those results is published.
Which benchmarks has Mercury 3 been tested on?
None yet. Mercury 3 has no published results on the 39 benchmarks behind AI IQ's Composite IQ. AI IQ only uses published, source-backed results, so its profile fills in as evaluations of this model appear.
How much does Mercury 3 cost?
Mercury 3 costs $0.20 per million input tokens and $0.70 per million output tokens. Adjusted for how many tokens it actually consumes on real tasks, its effective cost works out to $0.3998 per million input-plus-output tokens.
Is Mercury 3 open source?
No — Mercury 3 is a proprietary model. Its weights are not publicly available, so it is used through hosted APIs and products.
Who developed Mercury 3?
Mercury 3 was developed by Inception, based in the United States.
When was Mercury 3 released?
Mercury 3 was publicly released on October 19, 2026.
How large is the context window of Mercury 3?
Mercury 3 supports a context window of 1,000,000 tokens — the amount of text it can consider in a single request.
How fast is Mercury 3?
AI IQ doesn't have independent speed measurements for Mercury 3 yet. Speed comes from independent tests of a model's hosted API, which aren't available for every model — especially new, restricted-access, or self-hosted ones.
