Sol appears in OpenAI API, fueling GPT-6 release talk
A leaker says Sol has surfaced in the OpenAI API, speculating Astra is the base model and Sol gets heavy RL post-training, making it faster and cheaper with looser limits for Plus users.

🚨 GPT-6 Sol might be coming VERY soon. 👀 Sol showing up around the OpenAI API feels like a pretty fucking big signal. If the current theory is right, Astra is the base and Sol gets the heavy RL/post-training pass. Which could mean: Better. Faster. Cheaper. And potentially the model Plus users can actually hammer without babysitting their usage meter. Astra Low already feels better to me than GPT-5.6 Sol Max. Imagine what a properly post-trained GPT-6 Sol could do. 👀🔥
