OpenAI reportedly developing $500 ChatGPT Pro Max tier

The Vulkan backend commit (70c4e15) adds an int8 cooperative-matrix matmul path for AMD RDNA3 and RDNA4 GPUs. A user reports a massive performance improvement on a 7900XTX.

The 340M-parameter model takes text plus a schema of typed questions and returns structured answers, each with a probability distribution, confidence score, and constraint-feasibility metadata. It is open-weight and runs on CPU.

A r/ChatGPT user reports ChatGPT is the first AI to render their prompt for a photorealistic, unsettling Tooth Fairy with rows of collected teeth in her mouth. No other models or comparisons are named.

A Reddit user orchestrated five AI agents through Claude Code to make "The Most Boring Movie Ever (Ever) Made," a 3:12 video with outtakes about a sock puppet named Gerald facing a beige wall for 7 hours 46 minutes. Total OpenRouter cost: $16.87.

M5 Ultra (30/64) with 96GB offers 1.2 TB/s bandwidth and roughly 1.7x faster generation plus faster prefill; M5 Max (40-core GPU) with 128GB runs 614 GB/s but adds 32GB memory and costs less.

The Emacs ACP client adds a writeable prompt that stays available while the agent works, queueing new submissions automatically, plus turn steering for in-flight prompts via the session/steering ACP extension. Two agents join: Antigravity and Qoder.
