What it does
xAI’s Grok 3 API is here! Tap into Elon Musk’s bold, multimodal AI with powerful reasoning, 131K token context, and fast tiers. Choose Grok 3 or Grok 3 Mini based on your needs. Build edgy, smart apps with Grok.
Compare all current Grok models: capabilities, context windows, and per-token API pricing for text, image, video, and voice.
Our flagship model for code and everything else: agentic tool calling, minimal hallucinations, configurable reasoning. Real-time conversations, speech-to-text, and text-to-speech. Your choice depends on your use case. We have dedicated models and APIs for audio, image, and video capabilities. For everything else, including code, use Grok 4.6. It is the most intelligent and fastest model we’ve built. Some models have aliases to help users automatically migrate to the next version of the same model. In general: For most users, the aliased <modelname> or <modelname>-latest are recommended, as you would receive the latest featuresfrom docs.x.ai

Grok 4.2Feb 2026 · grok.com · ▲274Hi HN, I’ve been tracking the recent surge in Grok’s AI capabilities. According to the latest search data, "Grok Imagine 1.0" is seeing breakout growth, but there is a massive (+180%) spike in developer interest for the API side, specifically for video. I built grokimagine2.net to serve as a hub for what’s coming next in the Grok ecosystem. It focuses on the transition from image generation to high-fidelity video (which is currently the #1 trending topic in the niche). I'd love to get your thoughts on: The feasibility of Grok’s video model compared to Sora 2 or LTX. What you’d like to see in…

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
