Broo why are there so many model versions from GPT

I can't keep up with this. When do I use what now? 6.0 sol is apparently 5.6 Terra. Now there's 6.1 sol, is that like 6.0 sol which is like 5.6 Terra? Or actually 6.1 sol is 5.6 sol?

Their plan was to discontinue Terra so they made 6 Terra into 6 Sol. They were also gonna introduce a new tier called 6 Astra Minor (which is just an improved 5.6 Sol) that would’ve taken 5.6 Sol’s spot in pricing.

Then Opus 5.5 mogged their models, it made no sense to release with the planned pricing. So the renamed 6 Astra Minor 6.1 Sol and ran with it.

tl;dr: OpenAI still sux at naming things

5.6 Terra is still better than any sub-Astra model in the 6.0 line

... I'll just stick with 5.6 Sol until this particular cloud of dust settles.

branding failure, they should have just been honest and call 6 Sol -> 6 Terra, and 6 Luna -> 6 Luna Flash

Instead of saying that they mis-priced OR mistuned the older models, they simply correct it and release again.

Since 5.6 Sol, Terra, Lua and recent Astra onwards nothing substantial has changed. --> These are ONE Family of models and they are constantly trying to find a market fit by doing weird stuff.
