Is Amazon still in the foundation model race with Nova? Or are they just going all-in on being a model provider through Bedrock? They never released a reasoner, and their non-reasoning models have fallen well behind on both price and performance to many open weights models.

Improving AI Model Training with Enhanced Scaling Approaches
By
–
Good catch! This likely would be fixed with more robust training (more steps + rollouts, and ideally a larger than 1.5B model) 🙂 This was mostly just to show how it works. Feel free to try the same task with a larger model, more steps etc.

"there is no reason we can't make the context length 100 words, which is roughly what a human hears in his lifetime. There is no reason we can't do that. Its really inference support."

It's just training a very small LoRA you can merge back into the base model, so it should retain the context window!
