What OpenAI says

  • Designed for coding, computer use, and professional agent workflows.
  • Supports configurable reasoning effort from none through max and a 1,050,000-token context window.
  • Lower standard API token prices than its GPT-5.6 predecessor.

Limitations

  • Audio and video input are not supported.
  • Prompts above 272K input tokens incur higher rates.

Measured results are shown as published

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

How gaps are handled

Every dimension has at least one published result. Missing benchmarks can also draw on its predecessor, GPT 5.6 Luna; 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 gpt-6-luna?
gpt-6-luna has an estimated IQ of 125, which ranks #27 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 gpt-6-luna best at?
Among the dimensions with published benchmark results, gpt-6-luna ranks highest in Mathematical Reasoning (IQ 138, #18 of 176) and Computer Use (IQ 129, #19 of 176). Its lowest-ranked measured dimension is Abstract Reasoning (IQ 99, #62 of 201).
What is the EQ of gpt-6-luna?
gpt-6-luna 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 gpt-6-luna. AI IQ doesn't estimate EQ from other benchmarks, so the score appears once one of those results is published.
Which benchmarks has gpt-6-luna been tested on?
gpt-6-luna has published results on 26 of the 39 benchmarks behind AI IQ's Composite IQ, including AA Long Context Reasoning v1.1, GDP.pdf, CritPt, FrontierMath Tier 1-3 and SciCode.
How much does gpt-6-luna cost?
gpt-6-luna costs $0.10 per million input tokens and $0.50 per million output tokens. Adjusted for how many tokens it actually consumes on real tasks, its effective cost works out to $0.7684 per million input-plus-output tokens.
Is gpt-6-luna open source?
No — gpt-6-luna is a proprietary model. Its weights are not publicly available, so it is used through hosted APIs and products.
Who developed gpt-6-luna?
gpt-6-luna was developed by OpenAI, based in the United States.
When was gpt-6-luna released?
gpt-6-luna was publicly released on September 22, 2026.
How large is the context window of gpt-6-luna?
gpt-6-luna supports a context window of 1,050,000 tokens — the amount of text it can consider in a single request.
How fast is gpt-6-luna?
In independent measurements, gpt-6-luna generates about 124 tokens per second, with a typical response time of about 106 seconds.
