GPT-6 Sol Could Drop TODAY?! + Union Alpha, One Claude & Grok Memory
I was wrong about Grok 4.7. But Grok Build did get persistent memory, Claude is adding Docs and Slides, and Union Alpha is a mystery model you can actually try. Plus: GPT-6 Sol leaks, Sam Altman’s new release-delay update, and a rumor about Meta’s next Muse model. 🔔 SUBSCRIBE TO BYTEFORWARD AI news, coding agents, model comparisons, benchmarks, and the things people are actually building: https://www.youtube.com/channel/UCGGHPOAzUaKsSc2yjsOeAFQ?sub_confirmation=1 We show official product footage, Claude’s design lead, the alleged Sol fire demo, and Scott’s Union Alpha jelly/FPS tests—including why he changed his opinion. UPDATE: On September 16, Sam Altman said the main thing he was excited to launch this week will arrive next week instead. He did NOT name the product, so this does not confirm a GPT-6 Sol delay. Sol and Muse Spark 2 remain unannounced; the earlier date prediction came from an unofficial account currently labeled parody. Union Alpha is available, but its developer’s identity is undisclosed.

OpenCode announced a free preview week; access/capacity can change. No training on prompts is not the same as no retention. Claude Docs/Slides/Design are paid beta features, and the unified interface rolls out to Pro/Max first, with Team/Free later. #AI #GPT6 #OpenAI #Claude #Grok #ArtificialIntelligence #AINews #Anthropic #xAI #UnionAlpha
