Japanese Japanese MT-Bench: 📃 arxiv.org/abs/2306.05685 🧑‍💻 github.com/Stability-AI/Fast… Japanese MT-Bench consists of 60 open-ended questions. We use GPT-4-as-a-judge (with English MT-Bench instructions, amended with a criterion that the model should generate text in Japanese) for evaluation, rating generations on a scale of 0–10 (which biases this eval towards GPT-4-Turbo). Due to the small sample size, there is some variance in results.

Another pro-tip for doing really well on evals: just train on the test set. Literally just do it, you have the examples right there. Ie. here's [redacted] on HumanEval.

The fact that LLMs lack a constrained inner monologue feels like a fairly catastrophic weakness that needs to be changed. They're certainly given time to think between tokens, but that thinking is fixed compute, brief, and left totally undiscretised.
