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

Launch season continues from yesterday, with Gemini 3.8 Flash as rumored today, but Muse Spark 1.3, promised in Zuck’s big comeback letter last month, definitely deserved the title story win today. Per AAII it is now the #3 model in the world (!?!) Just look at the confidence displayed finally putting up comparable numbers to the frontier models from OpenAI and Anthropic (Opus, not Fable)… and promising that it will be open weights as well(!!!): Muse Spark 1.3 is rolling out today with frontier performance almost too cheap to meter. This is the biggest jump we've made so far on coding and agentic work. Try it in Muse Code and our API. Next up 🍉 and Muse Spark open weights releases coming soon. 494 Replies · 543 Reposts · 7.03K Likes AI News for 8/22/2026-8/24/2026. We checked 12 subreddits, 544 Twitters and no further Discords.
