Sakana AI's self-improving model gets better at solving and judging, but can't catch its own blind spots
Sakana AI’s MASS method lets one language model improve itself by solving tasks, judging results, and refining workflows, reaching a win rate of nearly 70 percent against the base model after two rounds. But when the model misses the same errors across all three roles, it can mistake them for progress and reinforce them during training.
Clearing chat history helps AI agents find better solutions
Microsoft researchers found that autonomous AI agents get trapped in what they call “idea basins” because of their growing chat context, local solution regions they can’t escape. Their “Fork-and-Flush” method clears the chat history but keeps the workspace, achieving up to 66 percent better results on the same compute budget.

AI agent teams waste massive tokens for barely measurable quality gains, research finds
Teams of AI agents barely outperform solo agents but cost up to 5.1x more, according to Vals AI. Only one out of four tests with GPT-6 Sol and Claude Opus 5.5 showed a measurable gain. Anthropic’s own data backs this up: beyond ten agents, quality plateaus while token costs keep climbing.
