The image editing capabilities of Gemini 2.5 Flash are really something else. I think there will be some really cool stuff built on top of this, can't wait to see it!

Want to bring 🤏🍌 into your app? Frontier image editing in Genkit is just a few lines of code away.
Available now, no need to upgrade your Genkit version. Just use the 'gemini-2.5-flash-image-preview' model and set responseModalities in config.

OK this is why you should always check your assumptions...for some reason I thought
(a) you can't await a promise multiple times
(b) you can't await a promise that's already resolved
Neither of these are true, so you can just do this.

Is there a better pattern than the snippet below for "async initialization classes" where the constructor needs to kick off async work but I want to "push down" waiting for that async to the methods?
I find myself using this pattern frequently but it feels clunky and ugly.

We've seen that lots of folks like getting started in the console (especially with our "natural language to schema/operations" features) and now there's a one-liner script to download a generated SDK from the console.

We also now support defining enums which are translated into Postgres native enums, but better than that these translate into strongly typed enums across all generated SDKs in JS, Kotlin, Swift, and Dart.
Enums can be filtered and even ordered (think log levels) like any other field.

I won't bury the lede...FULL TEXT SEARCH ON FIREBASE! 🤯
You can use the "searchable" directive to make any table in your schema searchable.
We manage the indexing for you with Postgres native FTS capabilities. You can also filter, order, etc like normal. Also multi-language!

We also support more than just tools! You can leverage prompts and resources from MCP servers and they are natively translated into Genkit prompts and the (brand new) resources support.

You can programmatically manage your MCP server connections including dynamically disabling, reconnecting, or efficiently updating the entire server config all at once.
We took many practices we're seeing from various MCP clients in the field and built them in.

Genkit v1.15 is out and includes a feature we've been cooking for a while: a completely revamped MCP plugin tailored for building complex "host" apps that connect to many MCP servers.
The new MCP Host capabilities let you pass in an "mcpServers" config...and we do the rest. ✨

It occurs to me that we probably already have a pretty accurate model for how "agents as employees" will play out: self-driving cars.
There are defined "autonomy levels" and we see those playing out in the market today for cars. Let's think about them in the analogous case of software engineering.

Okay this is totally a brag post but it feels pretty cool to have made a small contribution to the MCP spec!

A pattern I use frequently when coding with LLMs:
1. Stub out an interface (see screenshot)
2. Write guidance in comments in the function body
3. Prompt "implement someThing in @some-file.ts following the provided comments. Add unit tests. See also @other-file.ts for context."

This is why things like Genkit's Dev UI are so important. Big long workflow? Break it down into smaller chunks and rapidly play with those smaller chunks.
Find a set of inputs that you like to test, save it as an eval, make a change, run the eval. Tighter loop!

Maybe this is the disconnect with AI? How is an 800% productivity gain at a task not exciting?
If AI makes knowledge work more productive by some low multiple (say even 2x) and does nothing else that would be an enormously impactful and important technology!
