MCP 2026-07-28 drops initialize, session IDs, and SSE resume; Sampling, Roots, and Logging are deprecated. I wrote minimal servers for both specs and diffed them with curl.
Kimi K3 activates 16 of 896 experts per MoE layer. From the July 27 tech report: experts are sliced FFNs, not specialists, and the router is one linear projection.
M4 Mac mini postmortem: cron auth silently dead, a recall-0.19 model passing every promotion gate, 258 poisoned negatives, and a 5-config sweep to a usable trade-off.
Verified in SymPy: the 3-variable map from Alpöge's post has constant Jacobian determinant −2 yet sends three points to (−1/4, 0, 0). What changes for n ≥ 3 and what stays open.
Qwen3.8 Max preview tested via ambassador early access: OpenAI-compatible API behavior, reasoning_tokens, always-on thinking, and the unknowns behind the 2.4T parameter count.
Kimi K3 is API-only for now: a 2.8T MoE with 1M context via Kimi Delta Attention, open weights promised by July 27 under Modified MIT, and a reasoning-token overhead worth pricing in.
Self-patching on Qwen2.5 and Llama3 shows fine-tuned facts stall outside the mid layers; moving one hidden state lifts 2-hop reasoning from 0.078 to 0.793 (arXiv 2607.08393).
Merged a 4th girl with a makeup toggle into one Anima LoRA (518 images, rank256, 21.5h on RTX 5090). Epoch pick vs design bleed, why makeoff fails in multi-girl prompts, 6/6 one-shot.
Tested over 3 bakes on RunPod RTX 5090: a coined subtractive makeoff tag never fires at cfg 1.0, while additive earrings+makeup tags switch both ways with the face unchanged (ep140).
Swap 'spider' for 'ant' in Claude's mid-layers and 8 legs becomes 6. Anthropic's global workspace paper, the J-lens readout, eval-awareness detection, and its limits.
RL gains sit at 40-60% depth: on Qwen3-8B, training only layer 16 beats full-parameter RL (67.1 vs 66.5). Notes on arXiv 2607.01232 and what it doesn't claim about efficiency.
Measured on M1 Max ComfyUI: QIE 2511's pixel shift comes from the encode node's forced 1MP rescale. Stock ReferenceLatent fixes it; expression, outfit and pose diffs tested.
