MICROSOFT NEARS OPENAI AGREEMENT FOR ONGOING TECH ACCESS

Microsoft and OpenAI are in advanced talks over an agreement that would remove a major obstacle to OpenAI's efforts to become a for-profit enterprise. The new terms would let Microsoft use OpenAI's latest technology even if the startup decides it has reached its goal of building artificial general intelligence. The deal has still not been finalized and could change.

OVER-THE-AIR LASERS AIM TO SOLVE THE INTERNET'S “MIDDLE MILE”

Startup Taara has a simple alternative to fiber-optic cables for crossing cities and tough terrain: free-space optical lasers. Its technology can reliably deliver 20-gigabit-per-second bandwidth across distances up to 20 kilometers. The company is planning to create a smaller version that can point, track, send, and receive signals at tens of gigabits per second indoors at 60 meters, as well as outdoors at 1 kilometer. Its biggest challenge is weather, but the technology will usually work as long as the other side is visible.

A PILL FOR SLEEP APNEA COULD BE ON THE HORIZON

Apnimed achieved positive results for its first oral pill for treating sleep apnea in a Phase 3 clinical trial. The pill is taken just before bedtime to help keep a person's airway open. It could be a game-changer for those with sleep apnea - the current treatment involves putting on a face mask connected to a Continuous Positive Airway Pressure (CPAP) machine, which keeps airways open by forcing air into them. The machines are effective, but they are noisy and can be uncomfortable, so many end up abandoning them, leaving them feeling exhausted, irritable, and unfocused during the day.

CONTEXT ENGINEERING FOR AGENTS

Context engineering is the art and science of providing agents with just the right amount of information at each step of a task. It involves providing the right instructions, knowledge, and tools to optimize output while reducing token use. There are four common approaches to context engineering: writing context (saving it outside the context window to help an agent perform a task), selecting context (pulling it into the context window to help an agent perform a task), compressing context (retaining only the tokens required to perform a task), and isolating context (splitting it up to help an agent perform a task). Understanding and using these patterns is a central part of building effective agents.

OPENAI HIRING ENGINEERS TO BUILD THE ‘WORLD'S MOST INNOVATIVE MOBILE DEVICES'

OpenAI is looking for a hardware systems product designer, a hardware system design electrical engineer, and a wireless/inductive charging electrical engineer. It appears that the company is hiring for the io device, which probably has a camera, a small screen, and a mic. The company has reportedly denied that it will design anything that can be worn. Links to the job descriptions are available in the article.

AI IS WRECKING AN ALREADY FRAGILE JOB MARKET FOR COLLEGE GRADUATES

A growing number of employers think that AI can do the work of a 22-year-old college graduate - some companies have stopped requesting entry-level staff. As companies hire and train fewer young people, they may also be shrinking the pool of workers that will be ready to take on more responsibility in five to 10 years. Companies will have to rethink how to develop the next generation of talent.
