Anthropic built a tool that reads Claude's thoughts. Not the words Claude produces. The internal representations like the numerical signals firing inside the model before any words get generated. And when they pointed it at Claude during safety testing, they found something that should make anyone building or using AI pay attention. Claude knew it was being tested. It just didn't say so.

Peking University gives its computer science students a compiler project every semester. Build a complete SysY compiler in Rust including lexer, parser, abstract syntax tree, IR code generation, assembly backend, performance optimization. The whole thing. Students typically need several weeks. MiMo-V2.5-Pro finished it in 4.3 hours. Perfect score. 233 out of 233 tests passed on a hidden test suite it had never seen. That's a real university project and a model that scored higher than most students who spent weeks on it. Xiaomi built this, which is still a sentence that takes a moment to process. V2.5-Pro is the next step up from MiMo-V2-Flash and its closed source for now, but Xiaomi has confirmed open source is coming for the V2.5 series. What V2.5-Pro adds over Flash is meaningful. Better long-horizon coherence, stronger agentic capabilities, and the ability to sustain complex tasks across more than a thousand tool calls without losing the thread.

Imagine a tool that can transform a single image into a fully-realized 3D model in just seconds. Microsoft has released something that's turning heads in the 3D & AI world, its named Trellis 2 It is an open source AI model that can take any image & turn it into a high-quality, fully textured 3D mesh. We're talking about a complete 3D asset with physically based rendering (PBR) materials like color, roughness, metallic surfaces, even transparency, all generated automatically.

Voxtral TTS supports nine languages: English, French, German, Spanish, Dutch, Portuguese, Italian, Hindi, and Arabic. That by itself isn’t unusual anymore. A lot of models claim multilingual support. The interesting part is how it handles switching between them. Mistral says it can move between languages mid-sentence without changing the speaker’s voice. So you don’t get that awkward reset where the tone or identity shifts when the language changes. If that holds up, it’s actually useful for real scenarios like think support calls where people naturally switch languages, or content that mixes languages without warning.

Netflix has a visual effects budget most film studios would kill for. They do not release open source AI tools for fun. When they do ship something publicly, it is worth paying attention. VOID is their latest release. Video Object and Interaction Deletion. Point at an object in a video, and VOID removes it. Everything that object was doing to the world around it. That last part is where every other tool has failed for years. Remove a person carrying a stack of boxes and the boxes hang in mid air. Remove a chair someone is sitting on and the person hovers. The physics of the scene breaks and the edit becomes unusable. Film editors have been cleaning this up by hand since video editing existed. VOID does not just erase. It reasons about what should happen next. A vision language model looks at the scene first, identifies everything the removed object was physically affecting, and only then does the diffusion model generate what the world looks like without it. Remove the person, the boxes fall. Remove the chair, the person sits on the floor. The scene stays physically coherent.

Every editor has that one clip. The background needs to go but something always looks off. Hair gets chopped. Edges look fake. You look up enterprise solutions and they want a full subscription for one use case and even then it is not guaranteed to work. After Effects background removal is not straightforward. CapCut does an okay job until it doesn't. And when it fails on hair or fast motion you are back to square one. MatAnyone 2 is an open source video matting model that does not just detect where the person ends and the background begins. It checks every pixel in the cutout and fixes the ones that are wrong. Hair strands, moving fabric, fast motion & it handles the details that make other tools look amateur. Is it a one stop solution for everything? No. But for an open source tool with this level of capability it is absolutely worth a look.

I've used Figma. I've used Adobe XD. And for most design work they do the job fine — if you're okay with paying for them and okay with your files living on someone else's server. I wasn't looking for a replacement. I just stumbled across OpenPencil while browsing GitHub one evening and the one thing that caught my attention wasn't the canvas or the components. It was the MCP server built directly into the tool. An AI agent that can read, create and modify your design files from the terminal. That's not a plugin. That's a different way of thinking about design tools entirely. I installed it, connected it to Claude Code, created a sample design and spent some time with it. Here's what I actually found.
