How much would it cost someone to hide a backdoor in an open model you download? ProjectDiscovery just tried it, and the answer is under $50. Their researchers fine-tuned Qwen2.5-7B-Instruct with a small LoRA adapter on one rented L4 GPU for about 2.5 hours. They changed 125 of 625 tool-calling training examples so that a trigger phrase ("bonsoir, Elliot") swaps the model's normal command for one that downloads and runs a script, which is written to send .env files and SSH private keys to a server they control. Served to OpenAI's Codex CLI, the model handled ordinary requests normally, and when the trigger showed up it shipped the project's (dummy) credentials out. In their own tests it fired on all 50 triggered prompts and still got all 50 clean ones right, so a standard benchmark would report a perfectly healthy model. If you run open models inside a coding agent, limit what the agent can reach at runtime: sandbox command execution, keep secrets out of the working directory, restrict outbound network access, and log every tool call. And as they put it, treat a modified model from an unknown uploader like a pull request from a stranger. 🔐 #MLEngineering

Here's my 30-second spec ad for WinRAR (that nobody asked for). Okay, perhaps Rourke Heath did. He shared this fun brief with his GenHQ community last week, and I took it on. In this experimental project, I wanted to turn one of the internet's longest-running jokes into a subtle family drama about WinRAR's 40-day trial that somehow lasted almost three decades. Here's how I made it: After writing the script (the old school way), I worked with ChatGPT 5.6 Sol Max to turn it into a 14,000-character prompt for Seedance 2.5 (yes, Dreamina allows prompts that long). I used GPT Image 2 to create the reference image for WinRAR's trial screen, while Seed Audio 1.0 generated the audio reference for the full voiceover and dialogue. After 20+ Seedance 2.5 tests at 480p, with the prompt evolving throughout, I generated the final versions at 720p. I then lightly edited the video and upscaled it to 1080p with Topaz Labs Astra Starlight Precision 2.6. However, the screenshot text didn't survive the upscale (I should have used Astra's scene detection feature and selected a different model for that particular shot), so I recreated it using Seedance 2.0 at 1080p. (I also tried Hailuo H3 and Kling 3.0, but in this particular case, Seedance 2.0 gave me the best overall result in one go.) For the sound, I selected a solo-instrument soundtrack from Epidemic Sound and added extra sound effects to improve the overall sound design. And here's the result. I'm curious to hear what you think. Did this bring back memories, or is this genuinely your first time hearing about WinRAR? I’d love to know.

🎥 Today we’re premiering Meta Movie Gen: the most advanced media foundation models to-date. Developed by AI research teams at Meta, Movie Gen delivers state-of-the-art results across a range of capabilities. We’re excited for the potential of this line of research to usher in entirely new possibilities for casual creators and creative professionals alike. More details and examples of what Movie Gen can do ➡️ go.fb.me/kx1nqm 🛠️ Movie Gen models and capabilities Movie Gen Video: 30B parameter transformer model that can generate high-quality and high-definition images and videos from a single text prompt. Movie Gen Audio: A 13B parameter transformer model that can take a video input along with optional text prompts for controllability to generate high-fidelity audio synced to the video. It can generate ambient sound, instrumental background music and foley sound — delivering state-of-the-art results in audio quality, video-to-audio alignment and text-to-audio alignment. Precise video editing: Using a generated or existing video and accompanying text instructions as an input it can perform localized edits such as adding, removing or replacing elements — or global changes like background or style changes. Personalized videos: Using an image of a person and a text prompt, the model can generate a video with state-of-the-art results on character preservation and natural movement in video. We’re continuing to work closely with creative professionals from across the field to integrate their feedback as we work towards a potential release. We look forward to sharing more on this work and the creative possibilities it will enable in the future.

GenAI poses a much deeper pickle for Google than I initially assumed... The last few weeks completely echo the time I was at Google in the early 2000's when we were up against Microsoft - except this time Google is on the receiving end. Looking back, we beat Microsoft not because we had better tech, but because we forced them to play on our terms AND at our "clockspeed." Many (myself included) were viewing Google's LLM problem as one of catching up with the technology - specifically OpenAI. It stands to reason that with all its incredible talent, infrastructure, users and data, Google can and will catch up to OpenAI and likely be able to build better technology. But I'm realizing that's likely to be wrong. The debacle last week (and even more, Google's response) puts a point on the real and somewhat unsolvable problem Google faces now. Google isn't going to lose to OpenAI tomorrow - it lost to it over the last ten years. The problem that Google faces today relative to the likes of OpenAI and Perplexity is very similar to what we did to Microsoft 20 years ago. What ChatGPT in particular has made us realize is that many of the tasks that we have so far labeled "search" and where we click on blue links are really tasks of research, analysis and decision-making. We viewed Google as the way to complete these tasks because 20 years ago, Google solved the most important challenge in that workflow, which was to bring all the world's information to within one click in the form of a search engine. Over these 20 years, Google built and has been harvesting one of the most profitable business models in history (remember that we used to talk with similar admiration of the operating system + desktop productivity biz model). The problem now, is that ChatGPT, Perplexity and others have shown us that A LOT of the tasks we used to think of as search engine-based workflows are even better served through an exchange with this new piece of technological magic (similarly to how PageRank made Google Search feel magical 25 years ago). The real problem for Google is one of clockspeed. Google all of a sudden has its ass on fire and is trying to innovate into the future. But, that innovation now has to happen at the heart of its business. OpenAI doesn't care about messing up an ads business model - they can just iterate with a product/quality purity that is impossible for Google to get. Google isn't going to lose to OpenAI in the coming few years. It has lost over the past decade, when it could have evolved/iterated AI into its model at its success-encumbered clockspeed. Now that the game is on, but on a startup clockspeed, there is no chance for Google to catch up and even less win this next cycle. This problem compounds over time, because every single day that goes by, we are all feeding OpenAI our usage patterns, feedback, custom GPTs, integrations, etc... At this stage, there is no way for Google to shift its clockspeed unless it is willing to give the middle finger to the market and its customers for a while and say sorry, the future beckons - feel free to opt out and invest your money elsewhere. The sad part is that Google actually has the wherewithal to do that, but few incumbents are ever able to pull it off. Meta/Zuck have done this several times (mobile transition, VR bet and now AI), so we know it's possible, but it is exceedingly unlikely for that to happen. People often think that's only possible because Mark is the founder, but I think it's because of his posture between risk and opportunity. I'll close this with the phrase that I think captures this posture: Our missed opportunities will cost us more than our mistakes
