xAI just open-sourced Grok 2.5, releasing the weights for its top 2024 model on Hugging Face under a custom community license. It is free for research and non-commercial projects but bans training rival models. Musk also promised Grok 3 will go open source in about six months.
Elon Musk just announced that xAI will open-source its Grok 2 chatbot next week, sticking to his promise of releasing previous-generation models as new ones arrive. While giants like OpenAI lean into proprietary APIs, xAI is betting that handing developers the actual code will carve out a serious competitive edge.
xAI just confirmed that users can now ask Grok anything simply by replying to an X post with "grok". Powered by the rollout of Grok-2 and Grok-2 mini, the update turns any reply thread into a live AI chat without leaving the timeline.
Elon Musk just revealed that xAI's upcoming Grok 3 has finished pretraining, using 10 times more compute than Grok 2. He added that the new flagship model is coming soon. Why it matters: xAI is rapidly scaling its infrastructure to challenge OpenAI and Google at the very top of frontier AI.
Grok just rolled out a faster, sharper version of Grok-2 to everyone on X for free. The upgraded model runs three times faster with better accuracy and multilingual support, while bundling web search, citations, and the Aurora image model. Developers also get updated API endpoints at lower token pricing.
X is finally testing free access to its AI chatbot Grok, kicking off with users in New Zealand. Previously locked behind a Premium paywall, the free tier caps Grok-2 at 10 queries every two hours and requires a phone-verified account. Opening up to non-paying users should give xAI a much broader feedback loop to take on ChatGPT.
xAI just rolled out image understanding to Grok, allowing paid subscribers on X to upload pictures and ask questions about them. Elon Musk noted that the model can even explain jokes and memes, though the feature is still in its early stages. It's the latest step to turn Grok multimodal and give users more reasons to pay for X.
xAI just overhauled its entire inference stack from scratch in three days using the open-source SGLang framework. Grok-2 mini is now running twice as fast with slightly improved accuracy, while the full Grok-2 model gained much smoother multi-host inference speeds.
Google just rolled out its flagship text-to-image model, Imagen 3, to all U.S. users via ImageFX alongside a detailed research paper. While users praise its photorealistic textures and crisp typography, the model's ultra-strict safety guardrails are already triggering frustration over blocked harmless prompts.
xAI just dropped Grok-2 and Grok-2 mini into beta, claiming the flagship model beats Claude 3.5 Sonnet and GPT-4 Turbo on the LMSYS leaderboard. Alongside major jumps in reasoning and coding, xAI partnered with Black Forest Labs to bring FLUX.1 image generation straight to 𝕏. It is currently rolling out to 𝕏 Premium subscribers, with an enterprise API arriving later this month.
Elon Musk just revealed that xAI plans to launch Grok 2 this August, promising a major leap in real-time knowledge and reasoning. Musk noted the team did heavy lifting to purge junk from Internet training datasets, while teasing that Grok 3—powered by 100,000 Nvidia H100 GPUs—is slated for the end of the year.
