OPENAI TESTS CHATGPT AGENT UPGRADES POWERED BY NEW ALPHA MODELS

Summary from the TLDR AI newsletter

Some ChatGPT users have spotted a new 'alpha models' section in the model selector. The models appeared for a limited time, and they activated agent mode. The model naming - 'Agent with truncation' and 'Agent with prompt expansion' - suggests that OpenAI may be experimenting with different system prompt setups or underlying model architectures. The release seemed accidental and was quickly rolled back, making model comparisons challenging. The new agent variants appear to be aimed at early adopters, researchers, and power users interested in tool-augmented AI workflows.
