State sts_t: The current context which is the original user prompt and all tokens generated so far
Example: Prompt: "The sky is..." →\rightarrow State: ["The", "sky", "is"] in the token-space
How to close the loop between user behavior and LLM performance, and why human-in-the-loop systems are still essential in the age…
Moving beyond the slow, costly trial-and-error of RL, GEPA teaches AI systems to learn and improve using natural language.
AI safeguards can backfire when models learn to mimic the signals meant to verify truth. In one system, memory design and tool…
Study shows how patterns in LLM training data can lead to “parahuman” responses.
Leaders might assume that LLMs are able to offer a kind of unbiased, outside perspective. But new research found that leading…
Chain-of-Thought isn't a plug-and-play solution. For developers, this research offers a blueprint for LLM testing and strategic…
