xAI launches Grok-4-Fast: Unified Reasoning and Non-Reasoning Model with 2M-Token Context and Trained End-to-End with Tool-Use Reinforcement Learning (RL)

xAI introduced Grok-4-Fast, a cost-optimized successor to Grok-4 that merges “reasoning” and “non-reasoning” behaviors into a single set of weights controllable via system prompts. The model targets ...

How can I use the Recurrent_mini_batch_generator

I'm working on your code to deploy an RNN-style PPO. I noticed there has an Recurrent_mini_batch_generator in the RolloutStorage, and I also noticed that the PPO update function already includes the ...
