Pairwise benchmark snapshot · Aug 17, 2026noindex (thin pair)
This page compares AionLabs: Aion-3.0-Mini (aion-labs) and GPT-5 (OpenAI) using the latest snapshots we have as of Aug 17, 2026. AionLabs: Aion-3.0-Mini wins on output price at $1.4/1M. GPT-5 has the larger context window (400k tokens). Every cell below is a dated snapshot from a named public source — we do not invent missing scores, and we do not run SWE-bench ourselves.

AionLabs: Aion-3.0-MiniAuto-discovered from OpenRouter (aion-labs/aion-3.0-mini). Preview until a second source matches.
OpenAI
GPT-5OpenAI flagship reasoning model for 2025–26. Strong general preference Elo and multimodal coverage.
reasoning_effortReasoning models scale test-time compute by generating hidden chain-of-thought (CoT) tokens. These tokens are billed at standard output rates and directly expand latency (TTFT) in exchange for higher GPQA Diamond and SWE-bench Verified problem resolve rates.
Default evaluation baseline balancing reasoning depth with stream rate.
