OpenAI's GPT-6 Astra rates first place on Epoch AI's aggregate benchmark but ties its predecessor on Artificial Analysis. Its human-beating move efficiency on ARC-AGI-3 led ARC Prize co-founder François Chollet to call progress 2x faster than expected.

Meta Superintelligence Labs has launched Muse Spark, a native multimodal reasoning model that scores 52 on the Artificial Analysis Intelligence Index, placing it in the top 5 frontier models. This marks Meta's first frontier-class model and its first AI system without open weights, representing a strategic shift from its open-source Llama strategy. The model achieves comparable efficiency to Gemini 3.1 Pro while matching Llama 4 Maverick capabilities with over an order of magnitude less compute.

Artificial Analysis has released an updated speech-to-text benchmark showing ElevenLabs and Google as top performers. The benchmark provides comparative analysis of current speech recognition systems across multiple models.
