> This is a classic test request

Isn't this basically the model admitting it was trained on this? Otherwise why would it think a pelican svg is a usual request?

Plenty of times I’ve seen a model say “it’s a classic X” despite not being a classic anything. Might just recognize it’s a test in general, or it might just be a tic.

Dont conflate "I know this is test case" with it being trained on it.

But its safe to say that pelicans on bicycles are disproportionally huge part of their training data

It's the model admitting that it has heard of the test. It's been around for a couple of years now so I'd be surprised if it hadn't.

Doesn't mean Anthropic deliberately tried to train it to do a good job. If they DID train for the test their results are quite disappointing, I've seen better efforts from open weight Chinese models.

I think people just like to see the drawings at this point.

Not really. Of course it has pelican benchmarks in its training data. It likely has every article linked on HN in its training data. But that doesn't mean it was "trained on" the benchmark, as in specifically fine-tuned to make a better pelican. It just "knows" that the request is a benchmark.

It has read the internet. That doesn't mean it was literally RL'ed for this
