3 Shifts Edition (Nov 14 2025): Are rewards cards going away?, OpenAI's faster GPT-5.1, Teradar's cheaper lidar

November 15, 2025 • 6Pages

Hi everyone – welcome to your 3 Shifts Edition [AI-generated audio version].

First, Visa and Mastercard have proposed a sweeping settlement that could upend credit-card rewards as we know them. The $38B deal would let merchants refuse premium rewards cards and allow them to tack on card-specific surcharges.

Next, OpenAI dropped a faster and more conversational GPT-5.1, with adaptive reasoning that can assess the complexity of a query and allocate an appropriate amount of processing time to generating a response. The feedback seems to be markedly positive among developers.

Finally, Teradar emerged from stealth with a $150M Series B and a solid-state terahertz sensor that combines the best of lidar and radar – at a price point of a few hundred dollars. The startup hopes to integrate the sensor into production cars by 2028.

Enjoy.
