The Spark Fleet Learns to Run Itself
by Chris DePuy, 650 Group / October 21, 2026 The last month of desk-side serving stories were about engines. Athena put two frontier models on one 128 GB box at 262K context with a 141,519-token conversation restored from disk in 2.1 seconds; Imprint turned that same restore trick into a standalone context-cache service with a…

Five Spark Clusters, Two Kinds of Proof: TP5 GLM-5.3 Runs as Beam Sets the Efficiency Bar
by Chris DePuy, 650 Group / October 6, 2026 Five DGX Sparks now carry the full 753-billion-parameter GLM-5.3: an operator reported the first working five-board tensor-parallel build on Monday, with 1.5 million tokens of KV cache, prefill above 2,000 tokens per second, and 76 tokens per second single-stream — rising to 98–113 tokens per second…

Cloudflare’s Sharp Course Correction to AI
by Chris DePuy, 650 Group / October 5, 2026 Cloudflare closed its 16th Birthday Week on October 5 with 46 announcements across open source, post-quantum security, AI agents, and developer platform upgrades, and the occasion invites a wider read than one launch week. We scanned every post the company published on blog.cloudflare.com over the last…

Three Jev Alternates Landed in a Week: Cloudflare Clef, JEV-27B-VL, and the Open Decision-Model Family
by Chris DePuy, 650 Group / October 2, 2026 Three developments inside a week have moved decision models — the System One models that return typed, calibrated probabilities instead of generated prose — from a single hosted API into a crowded open-weights field. Cloudflare shipped two Apache-2.0 decision models, Clef and Clef-flash, post-trained from frozen…

System One Comes to the Agent Stack: Jev, Its Uses, and Its Open-Weight Alternatives
TypeSafe AI’s launch of Jev has spawned dozens of open reproductions in a week — and forced a clearer question than the benchmark race: which decisions in an agent loop ever needed a language model? by Chris DePuy, 650 Group / September 28, 2026 On September 14, 2026, TypeSafe AI released Jev, the first public…

New TensorFold LLM Model Serving Software Dramatically Improves Decode Speed on Macs and Sparks
by Chris DePuy, 650 Group / September 27, 2026 Two repositories shipped from one maintainer this week and made the same promise in two different places. On September 25 and 26, a developer publishing under the name Ash Hart released TensorFold, a local inference engine for Apple Silicon and NVIDIA GPUs, and Imprint, a tool…

New NVFP4 Checkpoints on Four DGX Sparks: The Results
Between September 9 and September 16, NVIDIA published first-party NVFP4 checkpoints for two frontier open-weight models, both MIT-licensed. One is a build of Z.ai’s GLM-5.3-Flash; the other is a build of DeepSeek’s DeepSeek-V4.1-Flash. Both labs produced them with NVIDIA Model Optimizer and validated both on rack-mount Blackwell silicon rather than on the desk. That distinction…

A Cross-Silicon Inference Loop: Two DGX Sparks, Two Mac Studios, and an Open RDMA Bridge
by Chris DePuy / September 19, 2026 On September 17, the community project pd-bridge published the result its earlier one-way design had been pointed at: a working closed loop in which two NVIDIA DGX Sparks prefill a 284-billion-parameter DeepSeek model, two Apple Mac Studios receive and serve the resulting attention state, and a multi-turn conversation…

The System One Split: Jev, CUA-S1-FORMS, and the Decision Layer Coming Beneath the Agent Loop
by Chris DePuy / September 20, 2026 Between September 15 and 18, four related releases arrived within four days. TypeSafe AI emerged from two years of stealth with Jev, a model class the company calls System One, LangChain published an integration guide showing Jev wired into agent middleware, Browser Use open-sourced Jev Ultrafast, a browser-agent…
