About this score
How much of grok-4's IQ is measured, and how the rest is estimated.
Every score in the benchmark tables comes from its source unchanged. Composite IQ averages all seven dimensions equally.
Computer Use and Knowledge Work have no published results yet, so their IQ is estimated from grok-4's other dimensions. Missing benchmarks can also draw on its predecessor, Grok 2; a predecessor is an estimation input, not evidence that this model has the predecessor's measured results.
Benchmark versions and evaluation harnesses can differ between sources, so small gaps between models may not be meaningful.

Frequently asked questions
Quick answers about grok-4, drawn from the same data as the rest of this page.
How AI IQ scores models →Get this data from the API →- What is the IQ of grok-4?
- grok-4 has an estimated IQ of 99, which ranks #132 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 grok-4 best at?
- Among the dimensions with published benchmark results, grok-4 ranks highest in Programmatic Reasoning (IQ 110, #93 of 177) and Reliability (IQ 112, #94 of 177). Its lowest-ranked measured dimension is Mathematical Reasoning (IQ 103, #118 of 176).
- What is the EQ of grok-4?
- grok-4 has an estimated EQ of 99. EQ measures emotional reasoning — how well a model reads and responds to emotional context — and is scored separately from IQ.
- Which benchmarks has grok-4 been tested on?
- grok-4 has published results on 19 of the 39 benchmarks behind AI IQ's Composite IQ, including MMLU-Pro, AA Omniscience, GPQA Diamond, LiveCodeBench and AIME.
- How much does grok-4 cost?
- grok-4 costs $3.00 per million input tokens and $15.00 per million output tokens. Adjusted for how many tokens it actually consumes on real tasks, its effective cost works out to $34.90 per million input-plus-output tokens.
- Is grok-4 open source?
- No — grok-4 is a proprietary model. Its weights are not publicly available, so it is used through hosted APIs and products.
- Who developed grok-4?
- grok-4 was developed by xAI, based in the United States.
- When was grok-4 released?
- grok-4 was publicly released on July 9, 2025.
- How large is the context window of grok-4?
- AI IQ hasn't verified an input context limit for grok-4 from its developer's documentation, so none is listed rather than guessing.
- How fast is grok-4?
- In independent measurements, grok-4 generates about 78 tokens per second, with a typical response time of about 16 seconds.
