there's a good chance gpt-6 sol ships this week. anthropic is already greyscale testing opus 5.2 in claude code under opus 5 name. early testing makes 5.2 look like a big jump over 5. still not astra level, but much better. and tibo is already vagueposting that this week's shipment is going to be insane. the timing lines up really well.
