Will OpenAI release an open source model before September?

This market will resolve to "Yes" if OpenAI publicly releases the weights of a reasoning model (e.g., o1, o3) or a large language model (LLM) that is as advanced as GPT-3 by August 31, 2025, 11:59 PM ET. Otherwise, this market will resolve to “No”. Multimodal models (e.g., DALL·E, vision-language models), speech or audio-based models (e.g., Whisper), specialized AI agents or reinforcement learning models (e.g., robotics, AlphaCode-like systems) or models that otherwise do not meet the listed criteria will not qualify. The resolution source for this market will be a consensus of credible reporting.
