> OpenAI dropped a bunch of new stuff today. Here’s my quick take:
> 
> 1. Dots
> 
> Some kind of OpenClaw alternative, I guess. I didn’t even understand half of it and honestly I don’t care.
> 
> 2. GPT-6.1 Sol
> 
> Good. Actually good.
> 
> Performance is almost at Astra level, but at Sol pricing. Pretty much exactly what we were waiting for, something that can finally put up at least some fight against Opus 5.5.
> 
> 3. The new $500 plan with Ultra Fast
> 
> I mostly don’t care about the plan itself, but I hate the fact that OpenAI were the first to push into the $500 subscription territory.
> 
> Now Anthropic can easily follow. OpenAI basically paved the road for even more user tier discrimination.
> 
> And the funniest part

> GPT-6.1 Sol ranks 5th on the AA Intelligence Index
> 
> Honestly, it feels like they just took Astra, cut the price, and called it Sol. Kind of a rushed rebrand after people roasted OpenAI, let’s be real.
> 
> I genuinely don’t understand these model names anymore. We got Sol, but it feels like Astra. Before that we had Sol, but it was basically Terra. Anthropic shipped this supposedly incredible Fable, and now Opus is their strongest model.
> 
> At this point it feels like they basically have two models: the strong one and the weaker one. Everything else is just some weird mix in between.
> 
> Why make it this confusing?

> I’m seeing a lot of negativity around OpenAI, so let’s separate the real issues from the noise.
> 
> Since GPT-6.1 Sol came out, I’ve been using it nonstop. In terms of usage, it honestly feels almost like Luna. My limits barely move. I even run it at the Max reasoning level, and it’s still more than enough for the project I’m building.
> 
> And that’s the main thing. For the most part, people got what they actually needed.
> 
> As for the complaints about the $500 plan and the $200 limits, I completely agree with those.
> 
> And the new Dots feature still isn’t available on my plan. Once it rolls out to me, I’ll definitely try it, although right now I don’t really see much potential in it.
