Microsoft is reportedly considering suing Amazon and OpenAI over their massive cloud deal centered on enterprise agent platform Frontier. While Microsoft eased exclusive hosting locks in October, it kept a clause requiring developer access to run through Azure, warning it will head to court if breached.
OpenAI just launched GPT-5.4 mini and nano, lightweight models built for high-volume workloads and tool-heavy coding. The mini variant runs over 2x faster than GPT-5 mini while nearly matching the flagship GPT-5.4 on SWE-Bench Pro, at just $0.75 per million input tokens. Nano drops the entry cost to $0.20, perfect for background subagents.
Encyclopedia Britannica and Merriam-Webster just sued OpenAI for "massive copyright infringement," alleging it scraped nearly 100,000 articles without permission to train its models. The suit claims ChatGPT starves publishers of revenue through verbatim outputs and RAG search, while falsely attributing hallucinated answers to their brand.
An Australian tech founder used ChatGPT and AlphaFold to analyze his dog's tumor DNA and target mutated proteins, teaming up with UNSW researchers to develop a bespoke mRNA vaccine in two months. Rosie's tumors have dramatically shrunk, showing how AI can rapidly accelerate and democratize personalized cancer therapeutics.
Meta has reportedly delayed its next-generation AI model, codenamed "Avocado," pushing its mid-March release to May at the earliest. Internal benchmarks showed the model lagging behind rivals from Google, OpenAI, and Anthropic in reasoning and coding, leading leadership to even weigh licensing Gemini.
OpenAI just updated its Video API with new capabilities powered by Sora 2. Developers can now generate clips up to 20 seconds, insert custom characters and objects, export in 16:9 or 9:16 aspect ratios, extend scenes, and run batch generation jobs. It gives developers significantly more control when building video products.
OpenAI is reportedly planning to integrate its Sora video generator directly into ChatGPT, according to The Information. The move mirrors last year's rollout of built-in image creation, aiming to win back users amid stiff competition from Claude, though it could also spike operating costs and deepen deepfake concerns.
OpenAI just upgraded its Responses API with a native shell tool, hosted container workspaces, and built-in context compaction for GPT-5.2 and later models. Agents can now run Unix commands like curl or grep concurrently, stage files, and query SQLite databases in sandboxes. It basically saves developers from having to build their own execution harness for long-running workflows.
OpenAI just released IH-Challenge, an open reinforcement learning dataset designed to enforce a strict instruction hierarchy (system > developer > user > tool) in frontier LLMs. Training internal model GPT-5 Mini-R on these tasks significantly boosted resistance to prompt injection attacks and safety steerability without triggering annoying over-refusals. Why it matters: As autonomous agents ingest messy web data and execute tool outputs, prioritizing trusted instructions is the only way to keep them from going rogue.
OpenAI just rolled out dynamic visual explanations in ChatGPT, bringing interactive widgets to more than 70 core STEM concepts like the Pythagorean Theorem and ideal gas law. Learners can tweak variables and adjust formulas in real time to see immediate visual reactions, moving beyond passive memorization. It is now live globally across all plans.
Nearly 40 employees from OpenAI and Google, including Google chief scientist Jeff Dean, just filed an amicus brief supporting Anthropic’s lawsuit against the Department of Defense. Anthropic sued after being labeled a supply chain risk for refusing Pentagon demands on mass domestic surveillance and autonomous weapons. Rival researchers argued that deploying frontier AI without guardrails poses profound risks to democracy and safety.
OpenAI just hit the brakes on its planned "adult mode" for ChatGPT, delaying the feature to prioritize core intelligence, personalization, and proactive agent capabilities. While the company insists it still believes in treating adults like adults, it admitted getting the safeguards and experience right will take more time.
OpenAI just announced plans to acquire AI security platform Promptfoo, trusted by over 25% of Fortune 500 companies. Once finalized, Promptfoo’s automated red-teaming, prompt injection detection, and jailbreak prevention tools will be baked directly into OpenAI Frontier, while its open-source CLI remains active. Why it matters: As AI coworkers gain access to sensitive enterprise workflows, proactive agent security is rapidly shifting from an optional plugin to essential platform infrastructure.
OpenAI robotics lead Caitlin Kalinowski just resigned from the company, sounding the alarm on government surveillance and autonomous weapons. While acknowledging AI's role in national security, she warned that domestic surveillance without judicial oversight and lethal autonomy without human sign-off are crossing dangerous ethical lines.
Oracle and OpenAI just abandoned plans to expand their flagship AI data center in Abilene, Texas, walking away from 600 megawatts of capacity after financing talks stalled. Meta is already in talks to lease the site from developer Crusoe, with Nvidia actively brokering the deal to keep its chips in the facility.
OpenAI just launched Codex Security, an application security agent designed to catch deep vulnerabilities while cutting false-positive noise by over 50%. It builds a threat model from codebases, verifies exploits in sandboxes, and proposes fixes. It's now in research preview with one month of free access for ChatGPT Pro and enterprise tiers.
Microsoft just confirmed it will keep Anthropic's Claude models available across M365, GitHub Copilot, and Azure, defying the Pentagon's new supply-chain risk label. Microsoft lawyers concluded the restriction only bars the Department of War, leaving commercial customers unaffected. Why it matters: Despite political pressure and defense-tech defections, Microsoft is holding the line to protect customer model choice and its $5B bet on Anthropic.
OpenAI is testing custom writing templates for ChatGPT that analyze your past emails and documents to mimic your personal tone. Leaked UI also reveals an "Animate" button to push static images directly into video generation, basically cutting down the tedious prompt work needed to sound like yourself.
OpenAI just launched ChatGPT for Excel in beta, letting users build, analyze, and update spreadsheet models using plain English. Powered by GPT-5.4, the add-in preserves native formulas, asks for confirmation before editing workbooks, and traces logic cell by cell. It also introduces live financial data integrations with Moody's and Dow Jones Factiva.
Anthropic just confirmed it received an official letter designating it a national security supply chain risk, and CEO Dario Amodei plans to fight it in court. Amodei clarified the restriction narrowly applies only to direct Department of War contracts, leaving broader commercial customers untouched. Why it matters: Even while apologizing for a leaked internal memo, Anthropic promised to keep supporting frontline troops at nominal cost during the transition.
