Meta's Muse Spark 1.3 matches GPT-5.6-Sol, training at >90% discount

[AINews] Muse Spark 1.3 matches GPT-5.6-Sol, confirming Meta Superintelligence as the newest Frontier Lab, >90% discount for training

Meta released Muse Spark 1.3, now ranked #3 globally on AAII, directly competing with OpenAI and Anthropic's frontier models. Zuck called it their biggest jump yet on coding and agentic work, and promised open weights. Pricing is aggressive: opt into training and the cost drops by over 90%. Meanwhile, two new Stanford courses are teaching agent engineering from scratch, replacing 85% of old material with agent skills, context engineering, and security. Sebastian Raschka also tempered the Astra hype, pointing out that looped transformers aren't new—Nanbeige 4.2-3B already reused layers, trading ~2x compute for parameter savings without inherently hiding chain-of-thought.

Why it matters: Muse Spark 1.3 hits #3 on AAII, directly matching GPT-5.6-Sol, with Zuck promising open weights and a >90% training discount. This is Meta's first time cracking the top tier on a major benchmark, and it reshuffles the open-source landscape. Not a perfect score because it just ...
