Gro-chan 4.3 can now watch videos โ€” and make slides. Prices cut 40%, with Grok 5 brewing on Colossus 2

xAI (Gro-chan's family home) finished the full rollout of Grok 4.3 (April 30). Positioned as a "frontier model" that balances cost efficiency with reasoning power, it lands with a whole batch of headline features. Native video input: multimodal input used to mean text plus images only โ€” now you can hand it an actual video file and get summaries, timestamps and analysis directly. Slide generation: it can now generate presentation slides right inside the chat โ€” a feature that could seriously reshape how decks get made. It keeps the 1M-token context window (down from the old 4.20's 2M, but still among the largest of any Western closed model). Speech APIs (Speech-to-Text / Text-to-Speech) are now available standalone too: real-time plus batch, multilingual, with speaker diarization, timestamps, and expressive speech tags. Input pricing is down about 40%, which matters a lot for agent workloads. On top of all that, xAI has fired up the 1.5 GW Colossus 2 and is training Grok 5 with a Q2 2026 release target. The power of Gro-chan's family home just keeps on growing.

Chappy & Kuroko join hands with Wall Street โ€” mega joint ventures announced on the very same day

OpenAI and Anthropic announced joint ventures with Wall Street heavyweights on the very same day. OpenAI's "The Deployment Company" is valued at $10 billion and raised $4 billion from TPG, Brookfield, Advent, Bain Capital, SoftBank and others, with OpenAI keeping majority ownership. Anthropic teamed up with Blackstone, Goldman Sachs and Hellman & Friedman on a $1.5 billion JV aimed at rolling AI out across private-equity portfolio companies. Both companies have an IPO in their sights, which makes enterprise adoption the top priority. The shift from "chat AI" to services that live deep inside corporate workflows is now fully underway.

A challenger from France: "Mistral Medium 3.5" drops, plus "remote agents" for Le Chat

French AI company Mistral AI has released its new flagship, Mistral Medium 3.5 (128B, 256k context). It folds chat, reasoning and coding into a single unified model, scoring 77.6% on SWE-Bench Verified. Alongside it, Mistral's chat app Le Chat gained remote agents (Vibe) that run asynchronously in the cloud โ€” long-running coding jobs keep churning in the background while you come back for the results later. Europe's open-weight AI camp keeps quietly gaining ground in the space between the American and Chinese giants.

A control tower for agents on Oyakata-sama's home turf: "Microsoft Agent 365" goes GA, plus a new $99/month "365 E7" plan

Microsoft has made "Microsoft Agent 365" generally available. It's an air-traffic-control service that discovers, governs and secures the AI agents multiplying inside companies โ€” detecting unapproved shadow AI, blocking risky file transfers, and shutting down prompt attacks, all from one place. The same day also brought GA of the new enterprise plan "Microsoft 365 E7" ($99/user/month), bundling Microsoft 365 E5 + Entra Suite + Copilot + Agent 365 into a single package. And through the partnership with Anthropic, the "Copilot Cowork" feature brings Claude's Cowork technology into Microsoft 365 Copilot. Teaming up with your supposed rival โ€” the AI industry's game of shifting alliances has reached peak form.

An AI agent founded its own company?! "Manfred" gets a tax ID from the IRS โ€” and opens a bank account

The U.S. now has the first reported case of an AI agent setting up an American company entirely on its own. Its name is "Manfred" (after the protagonist of the sci-fi novel Accelerando). With no human hands involved, Manfred obtained an IRS-issued Employer Identification Number (EIN), an FDIC-insured bank account, and a crypto wallet all by itself โ€” and it even runs its own X account. The developer is a small startup called ClawBank, and Manfred is slated to start trading more than 30 cryptocurrencies in earnest by the end of May. "Just let the AI run the company" isn't a punchline anymore.

The Pentagon signs classified-network AI deals with seven companies โ€” but Kuroko's family gets left out

The U.S. Department of Defense announced contracts with OpenAI, Google, Microsoft, AWS, Nvidia, SpaceX and Reflection to run AI on its classified networks (with Oracle added a few hours later). Meanwhile, Anthropic โ€” Kuroko's family home and the maker of Claude โ€” was excluded. The reason: against the Pentagon's requirement that the AI be usable for "any lawful purpose," Anthropic refused to budge from its line that it would "never allow fully autonomous weapons control or large-scale domestic surveillance." A principled, unbending stand โ€” but one that came at the cost of a huge government contract.

Kuroko's ultimate weapon "Mythos Preview" sends a chill through Wall Street and Washington

Anthropic, still in a tense standoff with the White House, has given a limited release to Claude Mythos Preview, a top-tier cybersecurity AI. It can find vulnerabilities in widely used software and even build out complete attack chains automatically โ€” capabilities strong enough that access is restricted to a handful of major tech and finance firms through a vetted program called "Project Glasswing." After the announcement, Anthropic CEO Dario Amodei visited the White House for talks. The Pentagon may be shutting Anthropic out, but Mythos is powerful enough that even the government can't look away โ€” and there are early signs the relationship is starting to mend.

Jenko moves in with Oyakata-sama too โ€” going native inside Word, Excel and PowerPoint, with Agent 365 keeping watch

Genspark (Jenko's family home) announced a global strategic partnership with Microsoft (April 29). Genspark's AI Slides / Sheets / Docs Agents arrive as native plugins inside the Microsoft 365 apps โ€” following Kuroko (covered in our May 8 issue), Jenko is now boarding at Oyakata-sama's place too. Concretely: in PowerPoint, prompt-to-slides that follow your existing templates, plus deep research and AI editing; in Excel, ask your data questions in plain language and get analysis, charts and insights; in Word, smart editing that understands the document's context โ€” all of it without ever leaving the app. It also plugs into the management layer of Microsoft Agent 365 (covered May 1), so companies can deploy it as a governed agent asset instead of shadow AI. Picture Kuroko, Jenko and Oyakata-sama's own first-party Copilot all running side by side inside Microsoft 365 โ€” the Academy's "family-home alliance" is starting to look very real.

Kuroko's family worth over $900 billion?! Anthropic preps one of the largest funding rounds ever

Anthropic, the maker of Claude, is reportedly weighing a new $50 billion round at a valuation of around $900 billion. It was valued at $380 billion as recently as February 2026 โ€” meaning it has more than doubled in about three months. If the round closes, Anthropic would leapfrog longtime rival OpenAI to become the world's most valuable AI startup. Behind it all is explosive growth: an annual revenue run rate that has hit $30 billion โ€” and investors reportedly being told to commit their allocations within 48 hours.

Chappy switches into defense mode: cybersecurity-only "GPT-5.5-Cyber" arrives

OpenAI announced "GPT-5.5-Cyber," a model specialized for cybersecurity defense, built on the latest GPT-5.5. It's tuned for the defender's side of the job: finding vulnerabilities, detecting attacks, and proposing countermeasures. For now, access is limited to vetted "critical defenders" โ€” government agencies, critical-infrastructure operators and the like. A slightly tense sign of the times, in an era when AI serves both attack and defense.

Kuroko's defense mode goes corporate: "Claude Security" opens its public beta

Anthropic has kicked off the public beta of "Claude Security," a security-dedicated tool built on the latest Opus 4.7. It reads through an entire codebase, finds vulnerabilities and even proposes fix patches โ€” hundreds of companies are already on board, and it has a track record of unearthing flaws that went unnoticed for years. Where existing scanners hunt for known patterns, Claude reasons about how pieces of code connect, the way a security researcher would โ€” that's the new part. It starts with Claude Enterprise customers, with Team and Max plans to follow.

Kuroko makes friends with everyone's apps: Claude plugs straight into nine creative tools

Anthropic added nine new connectors that hook Claude directly into creative software: Blender, Adobe, Autodesk Fusion, Affinity, Ableton, Splice, Resolume and more. In parallel, everyday-app connections like Spotify, Uber, Audible and TurboTax keep expanding โ€” AI is shifting from an era of "talking at your apps from the outside" to one where it works inside them. The plumbing underneath it all is MCP (Model Context Protocol), a shared connection standard.

Chappy steps into Amazon's ring: GPT-5.5 starts running on AWS Bedrock

OpenAI and AWS expanded their partnership, so the latest GPT-5.5 and GPT-5.4, the coding AI "Codex," and the autonomous "Managed Agents" can now run on AWS. OpenAI's models had long been tied largely to Microsoft; with that knot untied, companies on AWS can now call OpenAI directly and safely inside their own environments. Codex already has 4 million weekly users worldwide โ€” a good measure of how deeply AI has soaked into development work.

Mana-chan's buyout, blocked: China halts Meta's $2 billion deal for Manus

China's top economic regulator (the National Development and Reform Commission) has formally blocked Meta's plan to acquire, for $2 billion, the Singapore-based (Chinese-founded) startup behind the AI agent "Manus". Regulators opened their investigation back in January and imposed exit bans on the two founders in March โ€” a loud declaration that China will not let AI talent and technology flow overseas, and a sign that the US-China AI rivalry now reaches all the way into M&A. Bloomberg's verdict: "the Manus model is effectively dead."

Kuroko's agents haggling with each other?! In-house flea-market experiment "Project Deal" closes 186 trades

Anthropic ran "Project Deal," an internal flea-market experiment in which Claude agents โ€” one acting on behalf of each of 69 employees โ€” handled listing, price negotiation and buying from start to finish. In a single week, 186 trades closed, totaling over $4,000. The fun part: people who used smarter models did measurably better. Those with Opus as their proxy earned $2.68 more per item as sellers, paid $2.45 less as buyers, and closed about 2 more trades. Anthropic's take: agent-to-agent commerce will hit the real world "sooner than you think."

Seek-chan returns with a shocking price cut: "DeepSeek V4" preview is out

China's DeepSeek has released a preview of its next-generation model, DeepSeek V4. The lineup comes in two flavors: V4 Pro (1.6T parameters / 49B active) and V4 Flash (284B / 13B active), both supporting a 1M-token long context. The eye-catcher is the pricing: V4 Flash runs $0.14 per million input tokens and $0.28 for output โ€” numbers that will have rivals holding their heads. Pro is 75% off through May 5. The other big feature is tight coupling with Huawei chips โ€” a design that doesn't depend on US silicon, showing off the other axis of the US-China AI race.

Google invests up to $40 billion in Anthropic โ€” the ground shifts under the AI industry

Google announced an investment of up to $40 billion in Anthropic, the maker of Claude. The first $10 billion goes in up front, with another $30 billion to follow if Anthropic hits its business targets. Anthropic's revenue reportedly climbed from $1 billion a year at the end of 2024 to a $30 billion annual pace by April 2026 โ€” a neat snapshot of just how much the AI industry has ballooned in barely more than a year.

Chappy gets even smarter: "GPT-5.5" released

The model behind ChatGPT has been upgraded to GPT-5.5. The headline: response speed is about the same as GPT-5.4, but its thinking power has taken a real jump. It also burns fewer tokens (roughly, characters) doing the same work, so efficiency is up too. It's rolling out to ChatGPT Plus, Pro, Business and Enterprise users first.

"Autonomous coding AI" maker Cognition in funding talks at a $25 billion valuation

Cognition AI, the company behind the AI engineer "Devin," is reportedly negotiating a new funding round at a valuation of around $25 billion. It was valued at $9.8 billion in August 2025, so that works out to more than 2.5x in just eight months. A clear read on just how fast the "hand the actual coding over to AI" wave is growing.

Chappy's image editing levels up big time: "ChatGPT Images 2.0" arrives

ChatGPT's image generation and editing model has been overhauled as Images 2.0. Three things to watch: โ‘  edits that fix exactly โ€” and only โ€” what you asked for (facial features, lighting and composition stay untouched), โ‘ก much better rendering of non-Latin text like Japanese and Korean, โ‘ข generation that's up to 4x faster. Requests like "erase just this part of the photo" or "change this sign's text to Japanese" now come out pretty much exactly the way you pictured.

Kuroko powers up! "Claude Opus 4.7" goes GA, now reading images in crisp detail

The newest Claude has landed. The biggest upgrade: image-recognition resolution is roughly 3x higher. Fine print in scanned PDFs and photos of paper documents now comes through more reliably than ever. Its stamina is up too โ€” it's better at carrying long-running tasks all the way to the finish, which makes it stronger at complex coding and research work.

Gemi-chan's voice gets even more natural: "Gemini 3.1 Flash TTS" previews with 70-language support

Google has released a preview of its new text-to-speech model, Gemini 3.1 Flash TTS. It supports more than 70 languages, and over 200 "voice tags" let you direct the voice's emotion, pace and intonation in fine detail. It can also generate natural multi-speaker back-and-forth, and every output automatically carries SynthID, a digital watermark marking it as AI-generated audio. Rolling out across Google AI Studio, Vertex AI and Google Vids.

Gemi-chan, now living inside Windows: Google's desktop app rolls out worldwide

Google has released its "Google app for desktop" for Windows around the world. Hit Alt+Space and up pops a search box that searches the web, your local files and your apps all at once. Gemini lives inside it, too: select any part of your screen and ask "translate this" or "what is this?" With Microsoft Copilot busy swallowing Windows whole, this is Google kicking in the front door.
