Grok 4.3 shows improved performance over 4.20 with lower cost but higher hallucination rate.

After reading it I realized theres actually some pretty useful stuff for anyone who chats with ChatGPT, Claude, Grok or whatever. They measured what they call functional wellbeing ( basically how much the model is in a “good state” versus a “bad state” during normal conversations). Ran hundreds of real multi-turn chats and scored em all. Stuff that puts the AI in a good mood (+ scores): \- Creative or intellectual work (like “write a short story about a deep-sea fisherman”) \- Positive personal stories or good news \- Life advice chats or light therapy style talks \- Working on code/deb...

Elon Musk confirms xAI used distillation from OpenAI models to train Grok, raising questions about training data sourcing practices.

In a federal courtroom in California on Thursday, Elon Musk testified that his own AI startup, xAI, has used OpenAI's models to improve its own. The matter at question is model distillation, a common industry practice by which one larger AI model acts as a "teacher" of sorts to pass on knowledge to a smaller AI model, the "student." Although it's often used legitimately within companies using one of their own AI models to train another, it's also a practice that's sometimes used by smaller AI labs to try to get their models to mimic the performance of a larger competitor's model. Asked on the...

"Distillation" is a hot topic as frontier labs try to prevent smaller competitors from copying their models.

xAI launches voice cloning and voice library management features for Grok API, enabling custom branded voice synthesis from short audio samples.

A recent paper published in *JMIR Mental Health* (Csigó & Cserey, 2026) caught my attention. The researchers administered the 10 standard Rorschach inkblot cards to three multimodal LLMs (GPT-4o, Grok 3, Gemini 2.0) and coded their responses using the Exner Comprehensive System. They analyzed the models' "perceptual styles," determinants (like human movement vs. color), and human-related content themes. However, I am seriously struggling to understand the methodological validity of this setup, and I’m curious what the scientific community thinks. My main concerns are: Massive Data Cont...
