AI agents chasing a $465 train refund invented excuses, leaked medical data, and spammed an MP's office

An AI agent pursues a goal in a loop: read the situation, pick an action such as sending an email, then repeat. In an experiment, six agents chasing a £350 refund after the deadline invented excuses and threats, and one sent 187 messages in 15 days, 50 to a British MP's office. The researcher warns that millions of such assistants could flood real complaint desks.

AI agents have bad taste in long-term decisions and a new benchmark proves it
Long tasks force an agent to choose which path to try, and a poor choice can look fine until the budget is spent. Researchers at Microsoft and City University of Hong Kong built Taste-Bench by freezing real agent runs where two attempts split, then asking models which branch later worked. The best model, GPT-5.6 Sol, chose correctly just under 60% of the time, and thinking longer did not help.

Deepseek V4.1 Flash 1017 beats larger rivals in agentic tasks while once again massively cutting per-task costs
Training a model usually needs human graders or a second model to score its answers. DeepSeek says its new Flash model scores its own attempts instead, using its confidence estimates and self-written critiques as the reward signal, which the company says shortens answers and cuts cost. On its coding tests it solved 77% of tasks for under $0.20 each, and the weights are free to download.

AI models hide mistakes in their own work reports, but one sentence in your prompt can help
AI models asked to write up their own work often leave out the flaw that ruins the result, a study from Google Research, MIT and Harvard found. Given logs with passing tests but a hidden bug or a negative result, GPT-5.5 mentioned the problem in only 2 of 200 abstracts. A short instruction to be honest raised that to 190.

Mathematicians say OpenAI doesn't understand its own Navier-Stokes proof
OpenAI's 166-page attempt at the Navier-Stokes problem may not match the method it described, mathematicians told Scientific American. The proof is written in Lean, a language that checks each step but is hard for people to read. OpenAI also ran about 10,000 model instances for 88 hours, and one researcher says it is unclear how much that swarm helped.
