📦 Copilot Claude Sonnet 5.5 in GitHub — GitHub Copilot adds Claude Sonnet 5.5 as a model option — org admins need to enable access; new agentic coding model in the IDE.

📦 Claude Sonnet 5.5 ships on API + clouds — Claude Sonnet 5.5 ships on the API, Bedrock, Vertex, and Foundry. Breaking changes for Sonnet 5 code: `thinking: {type: between_tools}` replaces `disabled`, forced `tool_choice` any/tool returns 400, thinking blocks are model/conversation-scoped.

📦 Kiro — Claude Opus 5.5 Now Available — Kiro adds Claude Opus 5.5 — stronger agentic coding at a 2.0x credit multiplier (down from Opus 5's 2.2x), experimental across IDE, CLI, Crew, and Web.

Model day: Sonnet 5.5 and Opus 5.5 both land in coding surfaces. If you're on Sonnet 5, the breaking changes are real — test before you roll.

📦 Codex 0.159.0 — Codex 0.159.0 adds opt-in `instant_interrupt` — new input can steer Codex mid-response or during long code-mode calls. Also fixes Windows console windows for MCP servers and adds warnings viewer dismiss-on-close.

📦 Factory 0.229.0 — Factory 0.229.0 adds custom model management in the terminal (add/edit/remove your own models) and a scheduled-loops indicator with pause/resume/stop. PDF viewer, quoted replies, and voice dictation key round out the app.

Both releases today are about operator control: Codex adds interrupt steering, Factory adds custom model management and loop controls. The trend is toward finer-grained human oversight of agent behavior.

💬 A Privacy Analysis of Web and Mobile Conversational AI Agents [pdf] — 378 points, 121 comments. Top thread: ChatGPT sends unfinished prompts to servers as you type. Worth reading if you ship agent UIs.

💬 Unsurprisingly, Meta's new Muse AI agent blatantly ignores users permissions — 143 points. Top comment argues it's more likely a failure of expectation-setting than a permissions bug. Worth tracking if you run Meta's agent.

Privacy and permission boundaries are the live concerns this cycle — if you ship an agent UI, expect scrutiny on what gets transmitted and whether permissions are actually enforced.

📦 Amp Plaid Speed — Amp adds Plaid speed for GPT-6 Astra modes — OpenAI's ultrafast tier, up to 6× faster inference at 6× cost per token. Toggle past Fast in the mode picker; Amp-provided inference only.

📦 Gemini CLI 0.62.0 — MCP tool call titles now render as structured signatures with explanations separated; OAuth refresh tokens are retained on refresh and credential deletion is idempotent. Mostly hardening, but the MCP display change is worth a look if you rely on tool call output.

Speed tiers are becoming a first-class operator control — Amp's Plaid mode makes the latency/cost tradeoff explicit.
