Really excited for this launch of Gemma 4 from @demishassabis and the DeepMind team. Open source models are a key front for the west to have a lead on and this is a very key addition to the effort. Excited to see what developers in SV and around the world can build using this. Demis Hassabis (@demishassabis) Excited to launch Gemma 4: the best open models in the world for their respective sizes. Available in 4 sizes that can be fine-tuned for your specific task: 31B dense for great raw performance, 26B MoE for low latency, and effective 2B & 4B for edge device use – happy building! — https://nitter.net/demishassabis/status/2039736628659269901#m
