Is Gemini 2.5 Pro good at bounding boxes? Sort of.

It's been a year since we launched Go, and it's genuinely exciting seeing customers build and deploy agents solving very real and very complex problems. Now releasing Concierge, making agents accessible across your org, even if you've never written a prompt.

We’re launching Go Agents - a workflow builder focused on maximizing agent accuracy on long, multi-step tasks. We’re also releasing a generalist agent called Concierge, which delegates work to agents, acting as a central chief of staff for your users. Soon available via MCP.

This was a fun one to build. At ~3s, it felt broken. At ~1s (2.0 flash), it just clicked. Funny how much of a difference 2 seconds can make.

Worth noting that o1 doesn't handle system messages yet. Let's see if I can just put everything in user. .

I had a lot of fun working on this app. The 'intention' model was a ResNet-ish distilled model weighing in at less than 20 MB (the only way to get real-time image processing back in the day without burning up your phone). It was mainly a combination of metal shaders and neon.

In 2016 @SimEdw and I built a predecessor of Apple's new Visual Intelligence. Funny enough the use cases we filmed were very similar, yet they felt clunky and the app didn't succeed. Searching for an unfamiliar app to open just for a common query like logging a receipt was a

Without a comprehensive benchmark, changing model versions, provider or prompts can be scary and error-prone. A good benchmark tailored to your specific task makes all the difference. Public benchmarks are useful but not always applicable.

Also be aware that gemini assumes that the image is 1000x1000 px, so you will have to normalise on that too.

Changing the bounding box coordinate order from .{ y_min, x_min, y_max, x_max} to { x_min, y_min, x_max, y_max} (just the order).drops the performance to 0.71.

Tried Gemini 1.5 (Pro) for object localization (salient objects) using bounding boxes on the first 100 images in the DUTS dataset. The results are pretty good (avg IOU 0.84), not real difference between Pro and Flash. But you need to be very careful on how you prompt!

Spent 30 mins today puzzled as to why my Phoenix project was slowing down as the number of parallel requests increased (locally). Turns out, with code_reloader: true, each request triggers a sequential code reload via Phoenix.CodeReloader. Disabling it brought response times.
