Well, Actually: The Largest Open Model Ever Released Is Here, and Google Quietly Absorbed Your Favorite Note-Taking Tool
Moonshot AI released Kimi K3 2.8T-A50B, which the source identifies as the largest open model ever released, reportedly achieving Opus 4.8-class performance at Sonnet 5 pricing. Separately, Google rebranded NotebookLM as Gemini Notebook, preserving existing standalone functionality while planning deeper integration with the Gemini app and eventually Search. The model change appears minimal; this is fundamentally a packaging and integration maneuver.
The Kimi release demonstrates that open-weight model performance is now competitive with top-tier closed models at reduced cost, which should recalibrate your procurement assumptions. The NotebookLM rebrand illustrates a predictable pattern: useful independent products get subsumed into platform ecosystems, so you should anticipate workflow disruption and export your data proactively.
Moonshot AI built and released the Kimi K3 model. Google executed the NotebookLM-to-Gemini Notebook rebrand, with integration planned across its existing product stack.
Step 1: Visit the Kimi platform via moonshot.cn or its international interface and register for API access or web interface usage. Step 2: Test the same complex prompt on Kimi K3 and on a comparable closed model you currently use, then compare latency, cost (if API), and output quality. Step 3: Open your NotebookLM/Gemini Notebook account, navigate to export settings, and download your notebooks in a portable format to preserve independence from Google's integration timeline.
