Introducing EvalRouter by @KimptonAI. One API for evaluating any model against any benchmark. We built it because running an evaluation still means setting up a harness, provisioning sandboxes and babysitting long jobs. With EvalRouter you name a model and a benchmark and get

What this launch shows

From an account with 639 followers, this reached 542.2 times the account's own following. Accounts in the same band, under 5K followers, reach a median of 161.4 times their following, so this travelled about 3.4 times further than usual for its size.

It ranks 262 of 627 launches from accounts that size. Against every launch in the directory it is below the median of 688K views, at rank 1271 of 1981.

The response was thin for the reach: 41 bookmarks, 15 replies, 3 quotes and 16 reposts against 87 likes. Views arrived from people outside the audience the product is for, and they kept scrolling.

The first line is “Introducing EvalRouter by @KimptonAI”, the same first word as 25% of launches in the directory. It carries a 1:02 video against a directory median of 65 seconds. Videos between 30 and 90 seconds have a median of 603K views in the directory.

The copy runs 44 words, about the usual length for a launch post here, where the median is 41. The body carries a link, so the post had somewhere to send the reader and paid a little reach for it.

It went out on a Thursday. Launches posted on a Thursday have a median of 724K views in the directory, and Friday is the strongest day at 880K.

Launching a product on X from a small account covers this: an account with 639 followers has to earn every view from outside its own following. For the next one, read developer marketing strategy: developers try before they read, so the post has to let them.

X analytics explained is the guide for it: what each of these numbers means, with benchmarks by account size. Every launch we track in Developer Tool is on that vertical's directory page.
