THE TWO AI GATEWAY PATTERNS IN PRODUCTION INFERENCE

There are two dominant architectural patterns for AI gateways in production inference: access gateways that route outbound requests from applications to multiple model providers, and serving gateways that manage inbound customer traffic for organizations operating their own models. Serving gateways act as an essential control layer for identity, routing, protection, metering, and auditing when exposing proprietary models commercially.

DO CHATGPT & GOOGLE AI GET YOUR BUSINESS DETAILS RIGHT?

AI search often gives inaccurate business information, especially when a company leaves key details vague or unpublished. In a study of 600 businesses, 27% of Google AI Overview answers and 20% of ChatGPT answers included details the business did not publish. Google AI Overviews got 84% of answers right when businesses published clearly, compared with 63% when information was vague or missing. AI systems often fill gaps from third-party directories, so you should audit those listings and keep website copy, Google Business Profiles, and structured data consistent. Agencies can turn this into a quick audit by checking how Google and ChatGPT describe each client and correcting the sources behind inaccurate answers.

COMPETITOR EMAIL MONITORING: WHAT TO TRACK AND HOW TO DO IT

Competitor email monitoring helps brands spot patterns in how others approach email. Start by tracking 5-8 direct competitors each month and compare their send frequency and offer rates. Read their subject lines to see how they frame promotions and other messages. Open unusual emails and note what stands out or changes over time. Use those findings to identify gaps and choose one idea to test, rather than copying a competitor's strategy.

THE AMAZON CRO PLAYBOOK: HOW TO OPTIMIZE YOUR LISTINGS AND BEAT YOUR COMPETITORS

Amazon CRO works best as a research and testing process rather than a series of listing tweaks. Start by finding funnel problems in Seller Central, then use customer feedback, reviews, and user testing to identify specific objections and turn them into targeted listing changes. Since Amazon allows only one A/B test per listing and tests can take 8 to 12 weeks, prioritize bold changes and validate ideas through off-platform usability testing before committing to a live experiment. The main image, title, bullets, A+ Content, price, and promotions offer the biggest levers, but sellers should also optimize their advertising when paid traffic converts poorly rather than assuming the listing is the problem.

HOW TO CREATE A PRODUCT LAUNCH PEOPLE TALK ABOUT

A product launch only generates lasting attention when it gives people something to do beyond scroll past it, whether that is showing up somewhere in person, guessing what is coming, or filming something unusual enough to send to a friend. The brands getting the most mileage out of a launch treat it as an ongoing event instead of a single announcement, letting creators and customers do the distribution for free. None of it requires a bigger budget, just a reason for people to keep talking after day one.

CUSTOM GPT RETIREMENT AND MIGRATION FAQ

OpenAI plans to retire custom GPTs and transition users to plugins across all ChatGPT plans. Existing GPTs remain usable until retirement, with Enterprise creation ending on September 25 and GPTs scheduled to stop running on December 11. Migration will turn GPT instructions into a plugin skill and connected apps into apps, but custom actions will need to be rebuilt separately. Migrated GPTs become read-only, and users should test the replacement before switching. Plugin access and sharing will depend on account and workspace permissions.

MICE WITH HUMAN BRAIN CELLS OFFER A TOOL TO STUDY DISEASE. ETHICISTS ASK: WHAT'S NEXT?

Researchers have developed a technique for installing millions of human brain cells into mice. The scientists bred mice that were missing most of their cerebral cortexes and then replaced a large part of those missing mouse cells with lab-grown human brain cells. This resulted in mice with human neurons that could be altered to approximate human brain conditions. The technique could potentially create better scientific models for studying neurodegenerative disease.

INTRODUCING HOME MCP: ENABLING YOUR AGENT TO INTERACT WITH YOUR HOME

Google has opened early access to Model Context Protocol for Google Home in English for Google Home Premium Advanced users in the US. Any agent that supports calling MCP tools can now interact with all of the devices and event history in the Google Home ecosystem. The MCP allows agents to analyze and answer questions about home activity, summarize camera footage across rooms, manage devices, and create smart home dashboards using everyday language. It contains safety protections, such as prohibiting sensitive actions like unlocking doors, but depending on the agent, using the MCP can result in unexpected or even undesired behavior.

TRAINING A 4B MODEL TO PRODUCE 81% FASTER QUERY PLANS THAN POSTGRES

Query optimizers continue to leave much to be desired despite an enormous body of research. A Postgres database should know everything about the stuff that lives in its tables, but the problem is enormously hard. What's not as hard is verifying whether a query plan an optimizer picks is good or not. Language models are particularly good at learning how to do tasks with easily verifiable outputs. A small, open-weights model can be post-trained via supervised fine-tuning and agentic reinforcement learning to produce Postgres query plans that beat Postgres' default plans.
