Welcome back,
good to see you.
Good morning. Quiet on the release front today, but the benchmark boards were busy. Kimi K3 is putting up strong numbers: 90.3 on multimodal grounded, 89.5 on knowledge, 78.02 on coding, and 66.64 on agentic tasks, plus a solid showing on the LMArena leaderboard. Amazon's lineup also got scored, with Nova 2 Pro hitting 2 on gdp-pdf and the base Nova landing 3.6 on HLE, while Nova 2 Lite and Claude 3 Haiku both logged fresh arena scores. Nothing new to try just yet, but Kimi K3 looks like the one to watch. Enjoy your day!
