leo 🐾(@synthwavedd):Very much an uphill battle for OpenAI over the coming weeks. Imo it's 6.1 Astra tomorrow or bust - Fable 5.5 is on its way and coming sooner than most people expect, and considering the 5.x -> 5.5 leaps we've been observing across smaller classes, it's going to be a beast. *Haiku* 5.5 is likely to beat 6 Sol. Though Anthropic's biggest weakness is still token efficiency, where OpenAI continue to have the advantage In any case, I would expect a successor to 6 Astra next month at the latest. But will further RL be enough or does their next pretrain need to be wheeled out?
