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.
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.
Three LLMs converted the same 10 Japanese scene briefs into Anima (Qwen-DiT) prompts, generated as 60 fixed-seed images on an M1 Max with a merged 3-character LoRA. The Qwen-to-Qwen affinity hypothesis did not survive; a strict formatter brief with character-count locks is what actually moved the results, and two failure modes survive any prompt.
Anthropic disabled Fable 5 and Mythos 5 for all customers on June 12, 2026. US export controls, foreign-national employees, AI Safety gaps, Microsoft limits, and the shaky Opus 4.8 fallback.
Claude's new Microsoft Purview connector surfaces ~30 audit event types and on-demand chat/file access — but not prompts, model names, or tool calls. Claude Code goes through OpenTelemetry separately. Enterprise plan only; Team and consumer plans excluded.
Tested Orbis in Docker: psf/requests (35 modules) makes a clean 3D graph, expressjs/express (98 modules) collapses into one giant sphere. Notes on what tree-sitter actually captures for code-review prep.
uv 0.9.21 as the entry for small Claude SDK Python experiments: uv init, uv add, uv run, uv.lock keep agent projects reproducible across machines and Codex/Claude Code sessions. Operational notes, not a benchmark of the DEV article's uv 0.11.11.
Anthropic Labs released Claude Design on April 17, 2026 — a new design product that reads your codebase and existing design files to generate prototypes, slides, and landing pages. Here is a feature comparison with Figma and Canva, and a scenario-by-scenario guide to which tool to open when.
Measured: Opus 4.7 burns 1.2-1.45x tokens vs 4.6 in community benchmarks (Bill Chambers' Tokenomics Leaderboard, Claude Code Camp), beating Anthropic's official 1.0-1.35x range. CLAUDE.md alone hits 1.4-1.45x.
Anthropic released Claude Opus 4.7 on April 16, 2026. The staged rollout adds an xhigh effort tier, self-verification before returning, and roughly 3x higher-resolution image input, while intentionally capping cyber capability under Project Glasswing.
Running local models and still getting refusals? LLM safety stacks five layers: input filter, system prompt, RLHF, Constitutional AI, output filter. Where abliterated and uncensored variants cut, and which blocks survive on Gemini, Claude, and local LLMs.
