👋 Greeting post!
I'm Mark - I do Developer Relations at Google DeepMind, working on Gemini.
I'm keen to chat! Especially about LLMs, remote work, Python, coffee (like proper nerding out), bouldering, gardening & 3d printing.
I'm active on Twitter too: twitter.com/m4rkmc

How fast is #gemma3 270M out of the box on a @raspberrypi.com 5? About 30 tok/s on CPU for the Q4_0 model using #ollama. Tried using #llamacpp, got about 32 tok/s. 🤯
Extremely promising for edge compute with no accelerator! Model is only ~250Mb on disk. Can't wait to fine-tune for my IoT projects 👨💻

What should we add next to Gemini CLI’s MCP support?
1. 📚 Resources – fetch files, APIs, and DBs
2. 🧩 Prompts – reusable slash command templates
3. 🧠 Sampling – let servers trigger model calls
4. 🔐 OAuth – seamless authorization for private tools & data
