OpenAI Squeezed by Claude Fable 5.2 and Muse Ember

The AI model race is getting crowded at both ends of the market. According to Wccftech, Anthropic's Claude Fable 5.2 outperforms Fable 5.1, Opus 5.5, OpenAI's GPT-6 Astra and Google's Gemini 4 Carbon in nearly every benchmark. Meanwhile, Meta's Muse Ember is pressuring OpenAI's bargain-class GPT-6 Luna.
