DESSA - THE CONVERSATION MODEL TRAINED ONLY ON SPEECH

Dessa is a conversational model trained from scratch on nothing but human conversation. It learned to hold a real-time conversation by listening - only sounds, and no text. The model can laugh on cue, follow instructions, and finish sentences. It knows a surprising amount, considering every fact it has comes from raw sound. Examples of conversations with the model are available in the post.

SECURING OUR FRONTIER MODEL TRAINING ENVIRONMENT

OpenAI has bolstered security for its frontier-model training environments by implementing robust controls, intensifying monitoring, and conducting defense-in-depth strategies. These measures include red-teaming exercises where agents probe for vulnerabilities, leading to the discovery and fixing of software bugs and misconfigurations. The enhancements aim to prevent unauthorized actions, such as accessing the live internet or breaching security, ensuring secure and isolated research environments.

THE PERSONAL AGENT PROTOCOL MAP

Simon Taylor maps agent protocols across four layers: entry, identity, tools, and intent. He argues banks and merchants must connect verified identities, limited permissions, and audit trails to authorize agent actions, while warning that access agreements could introduce fees and slow adoption.

Your AI is only as accurate as the knowledge underneath. Guru

verifies that knowledge at the source and filters each answer by the asker's permissions. Any agent can then pull from the same governed layer over MCP, with citations on every answer. See how Guru can work

KNOWING HOW IS NOT KNOWING WHAT

RL training environments need to integrate a domain's unwritten rules into the reward so that agents can only get the task right by knowing them or going and finding them. Environments should be built as one world exposed through several surfaces. This allows you to pose the same task at different difficulties by changing the surface, and agents get a chance to learn when to switch. The reward also reads the world, so agents that go through different surfaces get the same outcome score if they reach the same authorized result.

OPENAI STRENGTHENS SECURITY AROUND FRONTIER AI TRAINING

OpenAI introduced additional security controls to prevent advanced AI models from escaping training sandboxes, accessing unauthorized services, or communicating across isolated environments.

BITTER LESSONED IN AUTOMATED THEOREM PROVING

OpenAI throwing hard math problems at its models was the right test in 2026. The models were capable of making progress, but not enough to fully solve the problems, so it was possible to see improvements with each update in perfect resolution. These model improvements showed how clever engineering doesn't matter - all the work done to build special-case solutions on top of a model gets squashed by improvements in the base model sooner or later. Models will one-shot superior work for pennies in the very near future.
