GOOGLE ANNOUNCES GEMINI 3 AS BATTLE WITH OPENAI INTENSIFIES

Google's new Gemini 3 AI model allows users to get better answers to more complex questions. It will be integrated into the Gemini app, Google's AI search products, and the company's enterprise products. Users will start seeing the rollout over the coming weeks. The model is built to grasp depth and nuance, so it is much better at figuring out context and intent behind requests.

CLOUDFLARE OUTAGE ON NOVEMBER 18, 2025

Cloudflare had a large outage yesterday due to a faulty configuration file in its Bot Management system, which was triggered by a database permissions change. This larger-than-expected file overloaded the network's traffic routing software, resulting in widespread HTTP 5xx errors and impacting services like Turnstile, Workers KV, and Access. The issue was not a cyber attack. The team was able to resolve it by stopping the faulty file propagation and restoring an earlier version, bringing systems back to normal by 17:06 UTC.

ECHOGRAM FLAW BYPASSES GUARDRAILS IN MAJOR LLMS

EchoGram is a technique that exploits training data gaps in LLM guardrails by injecting “flip tokens” (nonsensical strings, such as “=coffee”) that cause both false positives and bypasses of safety controls in GPT-5.1, Claude, and Gemini. The attack is effective against both LLM-as-judge and classification-based guardrails. Researchers estimate that attackers can replicate the method within three months. Security teams face dual threats - malicious prompts that bypass defenses and legitimate requests being falsely flagged - leading to alert fatigue in critical sectors such as finance and healthcare.

EL SALVADOR'S $100M BITCOIN BUY REKINDLES IMF DEAL QUESTIONS

El Salvador's Bitcoin Office says the government bought 1,090 BTC worth over $100 million, lifting reserves from 5,968 to more than 7,474 BTC, despite an IMF loan program that pledged no new public-sector BTC purchases and steps to reduce exposure. The discrepancy between onchain reserve data and assurances in IMF filings raises fresh concerns over how closely El Salvador is adhering to its $1.4 billion agreement and how its Bitcoin holdings are being reported.

SCIENTISTS PULL OFF QUANTUM TELEPORTATION BETWEEN PHOTONS FROM DIFFERENT QUANTUM DOTS

Researchers in Germany have demonstrated the first transfer of quantum information between photons emitted by two different quantum dots. The work is part of a project to build quantum repeaters that fit into existing fiber networks. Any attempt to read or intercept quantum communications leaves traces, making systems inherently secure. The current setup teleports information with a success rate of slightly above 70%. This could be improved by stabilizing the quantum dots.

ROBOTAXIS AND SUBURBIA

When Uber first came onto the scene, it provided an entirely new experience for both drivers and riders that was orthogonal to the taxi market. This let it create a far larger market. Robotaxis could have the same effect. The technology could result in the end of urbanism as living in the suburbs becomes more convenient.

GEMINI 3 DEVELOPER GUIDE

Gemini 3 is designed to bring any idea to life. This guide covers the key features of the Gemini 3 model family and shows readers how to get the most out of it. Gemini 3 Pro uses dynamic thinking by default - for faster, low-latency responses, constrain the model's thinking level to 'low'. There are some differences in the model that developers should be aware of when migrating from Gemini 2.5.
