DEEPSEEK UNVEILS FLAGSHIP AI MODEL A YEAR AFTER BREAKTHROUGH

DeepSeek has unveiled its V4 Flash and V4 Pro series, which the startup claims have top-tier performance in coding benchmarks and big advancements in reasoning and agentic tasks. The company says its Hybrid Attention Architecture technique helped improve the ability of AI platforms to remember queries across long conversations. The service capacity for the V4 Pro series is extremely limited due to a computing crunch. However, the pricing for the model is expected to drop significantly after Huawei launches its Ascend 950-powered computing clusters in the second half of this year.

OPENAI ANNOUNCES GPT-5.5, ITS LATEST ARTIFICIAL INTELLIGENCE MODEL

GPT-5.5 is now rolling out to OpenAI's paid subscribers. OpenAI claims the model excels at analyzing data, writing and debugging code, operating software, researching online, and creating documents and spreadsheets. It doesn't cross OpenAI's 'Critical' cybersecurity risk threshold, so it doesn't bring unprecedented new pathways to severe harm, but it does meet the criteria for OpenAI's 'High' risk classification, which means the model could amplify existing pathways to severe harm.

A HUNDRED ROBOTS ARE RUNNING A BIO LAB

Medra is a company that runs physical AI scientists governed by software that lets them operate lab instruments the way a trained human would. The company has opened a 38,000 square foot warehouse in San Francisco to automate biotech tasks for customers. Medra currently has five customers scheduled to run experiments across its robot army. Customers own their experimental data, but Medra retains the process knowledge.

STARTUP CLAIMS IT SUCCESSFULLY GREW HUMAN SPERM IN A DISH FOR THE FIRST TIME TO HELP INFERTILE MEN

Utah-based startup Paterna Biosciences claims it has successfully grown functional human sperm in a dish. The startup says it has even used these engineered cells to create visibly healthy-looking embryos. Paterna's team extracted sperm-making stem cells, placed them in a lab dish, and used computer models to calculate the exact chemical signals the cells needed to thrive. The procedure aims to recreate a healthy environment in the lab, then use the cultured mature sperm for fertilization.

‘TOKENMAXXING' AS A WEIRD NEW TREND

Companies are turning token usage into a benchmark for productivity and a competitive measure of who is most AI native. This is causing workers to maximize their prompts, coding sessions, and the number of agents working in parallel to climb internal rankings. This 'tokenmaxxing' behavior is burning massive amounts of tokens for little to no outcome, causing outages due to AI overuse, and producing throwaway, wasteful work. The metric can be easily gamed, and the outcome is just a massive AI bill.
