Chris(@ChrisGPT):Wow, Meta just dropped Muse Spark 1.3, and Google also dropped Gemini 3.8 Flash today! On the overlapping benchmarks Meta actually looks really strong. Muse Spark 1.3 beats Gemini 3.8 Flash on GDPVal-AA v2 (1754 vs 1545), DeepSWE (75.4 vs 73.7), and OSWorld 2.0 (66.9 vs 59.0). Gemini edges it on Terminal-Bench 2.1 (89.4 vs 88.8). (Google DeepMind) The long-context numbers are probably the craziest part for Meta though: 98.5 on MRCR 256K–512K and 98.1 from 512K–1M, vs 91.5 and 73.8 for GPT-5.6 Sol! I think the craziest one to me is that it beats Opus 5 on DeepSWE and Terminal-Bench, but Opus is a beast on GDPVal and OSWorld. Great Job to the team at meta for cooking on long context!
