GPT-6 Astra writes four-part Bach-style piece without harmony errors

MG Siegler argues Google should have built Meta's Muse personal assistant agent, since Muse depends on Gmail, Google Calendar, and Search hooks. Google's rival, Gemini Spark, is still in testing, limited to US users on Ultra and now Pro tiers.

A Reddit user in r/StableDiffusion describes spending a day generating AI videos from a single image plus a highly detailed prompt covering camera movement, character actions, and timing, and finding most attempts frustrating. The poster concludes the missing piece was the right inputs rather than more prompt detail.

Across 11 open-weight and 8 closed models on the Artificial Analysis Intelligence Index, the cheapest open-weight model completes a task at roughly one fifth the cost of a comparable closed model. Self-hosting on rented hardware drops to $0.12-$0.35 per million output tokens at full utilization, and on gpt-oss-120b the A100 beats the H100 on output cost.

GPT-6's prompt caching adds explicit breakpoints, higher cache hit rates, and new diagnostics. OpenAI says the controls cut latency and costs for developers.

The Extreme variant runs a 30B-parameter mixture-of-experts model locally, while new sensing hubs handle models up to 200M parameters for local scribe and voice agents. Apple's WWDC 20B MoE model is the comparison point.

Meta's opening keynote livestream frames the company's pitch as "putting superintelligence in everyone's hands," alongside new AI, AI glasses, and VR technologies. The stream is available with virtual content in multiple languages via Meta.com/connect.
