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

Programmatic Reasoning, Computer Use and Knowledge Work have no published results yet, so their IQ is estimated from opus-3'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 opus-3?
opus-3 has an estimated IQ of 80, which ranks #175 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 opus-3 best at?
Among the dimensions with published benchmark results, opus-3 ranks highest in Abstract Reasoning (IQ 75, #182 of 201) and Reliability (IQ 86, #173 of 177). Its lowest-ranked measured dimension is Mathematical Reasoning (IQ 71, #175 of 176).
What is the EQ of opus-3?
opus-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 opus-3. AI IQ doesn't estimate EQ from other benchmarks, so the score appears once one of those results is published.
Which benchmarks has opus-3 been tested on?
opus-3 has published results on 7 of the 39 benchmarks behind AI IQ's Composite IQ, including MMLU-Pro, SimpleQA Verified, Chess Puzzles, SciCode and GPQA Diamond.
How much does opus-3 cost?
opus-3 costs $15.00 per million input tokens and $75.00 per million output tokens. Adjusted for how many tokens it actually consumes on real tasks, its effective cost works out to $51.65 per million input-plus-output tokens.
Is opus-3 open source?
No — opus-3 is a proprietary model. Its weights are not publicly available, so it is used through hosted APIs and products.
Who developed opus-3?
opus-3 was developed by Anthropic, based in the United States.
When was opus-3 released?
opus-3 was publicly released on March 4, 2024.
How large is the context window of opus-3?
AI IQ hasn't verified an input context limit for opus-3 from its developer's documentation, so none is listed rather than guessing.
How fast is opus-3?
AI IQ doesn't have independent speed measurements for opus-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.
