The founder of HuggingNews recaps a crowded day of model launches: OpenAI's GPT-6 Sol, Anthropic's Claude 5.5, xAI's Grok 4.7, and Xiaomi's open-weights MiMo-V2.6. The verdict is lukewarm across the board — Grok 4.7 reviews are mixed to negative, using more tokens without clearly beating 4.6; GPT-6 Sol cut prices on Astra without clear capability gains; Opus 5.5 performs better at 'med' effort than higher effort and is not very token-efficient. He also notes his aggregator's auto-generated release stories skew metrics-heavy and plans to surface community reactions faster.
