OPENAI DEVELOPS SHARED CHATGPT PROMPTS FEATURE FOR TEAMS

OpenAI's Prompts feature within team workspaces for ChatGPT appears to be aimed at organizations. It creates a library of shared prompts made by team members accessible across the team. Team members are able to create prompt templates, set custom instructions, and integrate variables. Teams will be able to package up complex, multistep tasks into single prompts using built-in tools.

AI AT WORK: OPENAI'S WORKFORCE BLUEPRINT

GPT-5-level models now match human professionals on roughly half of economically valuable tasks, completing work in minutes that would take a human hours. OpenAI has proposed a retraining program targeting 10 million Americans by 2030, acknowledging evidence that AI is already displacing entry-level workers. The company frames AI as "more enabler than replacer" despite proposing a massive retraining initiative, which has historically failed to prevent job displacement from technological change.

INTRODUCING SWE-GREP AND SWE-GREP-MINI: RL FOR MULTI-TURN, FAST CONTEXT RETRIEVAL

Cognition trained specialized models that retrieve code context 10x faster than frontier models by using RL to issue up to 8 parallel tool calls per turn instead of the sequential searches typical agents use. Speed matters more than the industry realizes because it allows developers to stay in a flow state.

THE ART OF SCALING REINFORCEMENT LEARNING COMPUTE FOR LLMS

ScaleRL is a framework for analyzing and predicting compute scaling in LLM reinforcement learning. Their large-scale study shows that stable training recipes yield predictable performance curves, aiding efficient resource allocation.

RECURSIVE LANGUAGE MODELS

Recursive Language Models (RLMs) can decompose and recursively interact with their input context as a variable. An RLM using GPT-5-mini outperforms GPT-5 with more than double the number of correct answers on OOLONG while being cheaper per query on average. RLMs outperform other methods ReAct + test-time indexing and retrieval over the prompt without any degradation in performance when given over 10 million tokens at inference time. RLMs trained explicitly to recursively reason are likely to be the next milestone in general-purpose inference time scaling.
