Price receipt
We read OpenAI's own pricing page on Aug 25, 2026 and found o3 listed with a price on the same row — that read is where the number above comes from, recorded as a new model. We keep the page text we read; its content hash is cff825ba22.
Overview
OpenAI's April 2025 reasoning model for complex tasks, succeeded by the GPT-5 line but still sold first-party at its own rate. 200K context window, 100K max output tokens, text + image input, text output, June 2024 knowledge cutoff. The default snapshot behind the alias is o3-2025-04-16.
Capabilities
struck through = not supportedBenchmark performance
accuracy % · higher is betterWe hold no per-benchmark accuracy scores for this model yet, so it has no accuracy average. That is a gap in our coverage, not a sign the model is untested — independent evaluators often publish a composite index for a new model long before releasing its per-benchmark numbers. The percentile above is its standing across the independent composites below.
- AA-Omniscience Index: -15.6 (−100–100)
- Ranks #83 of 170 comparably-measured models by percentile score, across 1 independent measurement
- Ranks #139 of 170 comparably-tested models by normalized performance per dollar
