Meta has acquired Limitless, a startup known for its AI pendant that records conversations. Limitless will cease hardware sales but continue to offer support for a year. Its team will focus on supporting Meta's existing AR and AI wearables rather than launching new products. The acquisition comes amid rising competition in AI hardware as major players like Meta expand their device offerings.

<strong>Titans + MIRAS: Helping AI have long-term memory (12 minute read)</strong>
</span>
</a>
<br>

<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
Google Research has released two new papers introducing an architecture (Titans) and a theoretical blueprint (MIRAS) that combine the speed of recurrent neural networks with the accuracy of transformers. Together, Titans and MIRAS advance the concept of test-time memorization, the ability of an AI model to maintain long-term memory. They introduce a meaningful shift toward real-time adaptation. The architecture actively learns and updates its own parameters as data streams in, enabling the model to incorporate new, specific details into its core knowledge instantly.

<strong>Computer-science Reinforcement Learning Got Rewards Wrong (6 minute read)</strong>
</span>
</a>
<br>
<br>
<span style="font-family: "Helvetica Neue", Helvetica, Arial, Verdana, sans-serif;">
In reinforcement learning, the reward is part of the agent, not part of the environment. Once we start thinking in terms of the reward translation as being part of the agent, we can also start thinking of ways in which the agent can affect the reward translation mechanism. It could be dynamic and change across time, be tied to policy, or even learned. The shift in perspective creates many possible options, just by changing the notation - because notation matters.
