Coding agents & LLM mechanics

OpenAI shipped GPT-5.6 family — three sizes Luna/Terra/Sol, priced $1-6/$2.50-15/$5-30 per 1M tok, now GA and rolling into GitHub Copilot (launch, Copilot rollout).

Six-figure token spend teardown of Sol vs Fable 5, covers code-quality gap and loop/subagent behavior — worth watching for real benchmark signal, not marketing (podcast).

Meta launched Muse Spark 1.1 — agentic/coding-tuned, 1M context, parallel sub-agents, aggressive pricing via new Meta Model API (announcement, details).

45k-star repo system_prompts_leaks dumps real hidden system prompts from Claude, GPT, Gemini, Grok — direct prompt-engineering source material (repo).

codebase-memory-mcp — tree-sitter based code intelligence MCP, indexes repos (Linux kernel in 3min), sub-ms structural queries, 99% fewer tokens vs raw grep — relevant for context/token-cost reduction in agentic coding (repo).

Guy vibe-coded a full training pipeline with GPT-5.6, trained a 1.38M-param 4-layer transformer locally on his Mac from iMessage history — small model, custom tokenizer, mimics his writing style (thread, specs).

Matt Pocock walks his 160k-star skills repo end-to-end: /grill-with-docs, /to-spec, /to-tickets, /implement, /code-review flow (video).

addyosmani/agent-skills — production-grade engineering skills encoding senior-dev workflow gates (define/plan/build/verify/review/ship) for coding agents (repo).

Karpathy interview on where agents/coding/research are heading — worth the watch for framing, not tactical (thread).

Agentic SaaS

Anthropic launched Claude Tag — tag Claude into a Slack channel, it spins up sandboxed Claude Code instance per thread (own memory/permissions), clones+writes+tests+compiles, sandbox torn down after. Beta today for Enterprise/Team (announcement, mechanics, proactive behavior, availability). Anthropic's own product team already gets 65% of new code from their internal version — signal this isn't just a demo (internal usage).

stablyai/orca — ADE for running fleets of parallel coding agents (Codex/Claude Code/OpenCode/Pi) each in own worktree, one tracked view, usage/rate-limit tracking (repo).

MagicPath 2.0 — multiplayer canvas where humans + Codex/Claude Code build UI together in real time from codebase/data (announcement).

Open-source video editor fully driveable by Claude via MCP — editing, motion graphics, audio mixing (reddit).

Aura — OSS IDE for controlling coding agents with built-in loops (producthunt).

Vibe-coding & repos

calesthio/OpenMontage — open-source agentic video production system, 12 pipelines, 52 tools, 500+ skills, turns coding assistant into full video studio (repo).
