• 2026-10-19 Inception announces Mercury 3 (~3:00 PM ET — https://www.unite.ai/inception-releases-mercury-3-its-flagship-diffusion-llm/), describing it as "the most capable diffusion-based large language model" — the record's first thread on diffusion architecture as a model-release category. Announced, not shipped: no pricing, availability, or independent benchmark detail in the capture, and the capability framing is the vendor's own. Watch: weights/API access actually becoming available, Artificial Analysis-class independent scores vs the "most capable diffusion LLM" claim, and whether diffusion models keep claiming a speed/cost lane against text-stream frontier models.
