This Banana Pro model by Google is pretty good at turning docs into visuals, here by the example of the Claude Agent SDK overview page platform.claude.com/docs/en/agen...

Tried a couple of things today across gpt5.1, sonnet 4.5 and Gemini 3 in their respective web UIs - Gemini 3 was quite a lot better in matching my expectations for the given prompts and might become my daily driver for non coding tasks.

Too many ideas of what I'd like to build, and the question is shifting from "can I build this" more towards "do I wanna support this" - to which the answer is no almost always no :D

"Google Antigravity is so advanced, it's setting up my account in a different dimension. I've aged 5 years and I still haven't reached the next dot. At this rate, the Gemini model will have finished writing its own sequel before this loads. " - Gemini 3 about the Google Antigravity loading screen

The ultimate unlock... Gemini 3 + Gemini CLI has arrived 🚀🚀🚀
Now to avoid melting too many TPUs we're going to be iteratively rolling out the support (it's quite epic). See blog post for more details: developers.googleblog.com/en/5-things-...

I created a MVT Tileserver based on DuckDB and the spatial extension:
github.com/tobilg/duckd...
Just create a new DuckDB database with one or more tables with a geometry column, and use it when starting the server.
Or, create a view that points to a remote dataset, e.g. a GeoParquet on S3.

Trying a claude skill in claude.ai to interact with Google Drive apis or GCP apis, but it seems like thats blocked for some reasons. Other apis / urls seem to work though, a bit weird. Maybe that's more Google itself blocking the requests, I guess.

What if you don't need MCP at all?
Got Bash and some code interpreter? Skip MCP.

It's a tiny (<10kb gzipped) wrapper around @duckdb.org WASM that can run queries interactively, and be embedded in plain HTML websites, as well as all other mayor frontend frameworks...
It's an early version, feedback warmly appreciated!
