Sam Altman has signaled that he will open-source o3-mini, or perhaps an even smaller model which can run on phones. He has also indicated that OpenAI might adopt a broader policy of releasing mini versions of successive generations of models.

Conditional on OpenAI releasing the weights of a model based on o3-mini, this market resolves YES if OpenAI releases the weights of a model broadly more powerful model than o3-mini before July 2026. Note that if OpenAI releases a distilled version of o3-mini, a qualifying next model must be better than o3-mini itself, not just the distillation.

My criterion for “more powerful” is roughly “a pareto improvement across most benchmarks.” Successive generations of models tend to be better in this way, so I expect this to be clear to judge. However, in the case of ambiguity I will defer to a panel of 3 mods.
