Inference hardware cluster: Blackwell + Groq LPU v3 + Cerebras WSE + Apple MLX 1.0 + Inferentia3 + TPU v6 — every vendor ships a Blackwell-era answer

The week of 2026-08-04 saw a cluster of inference hardware and framework announcements: NVIDIA Blackwell B200 (FP4/FP8 + NVLink Switch + DGX SuperPOD), Groq LPU inference engine v3 (deterministic token-stream latency regardless of batch size), Cerebras WSE (wafer-scale single-chip inference + cloud SDK), Apple MLX 1.0 + MLX-LM (on-device LLM inference for Apple Silicon with unified memory), AWS Inferentia3 + Neuron SDK v3 (production inference on Neuron-compatible instances), Google TPU v6 Trillium (managed inference via Vertex AI). The Decoder frames the cluster as 'every inference vendor ships a Blackwell-era answer' — the GPU generation has become the unit of competitive positioning, and every vendor has picked a lane.
