🚀 Headlines (30 sec read)

• Alibaba kicks off Apsara Conference — Qwen 4 confirmed in training, new chips unveiled — a trillion-GPU-memory accelerator and a mobile agent platform round out a full-stack AI push from Hangzhou.
• Xiaomi open-sources MiMo-V2.6, a trillion-parameter omnimodal model — Pro tops the open-weight leaderboard on Artificial Analysis; Flash runs $0.14 per million input tokens.
• OpenAI is quietly building a Codex mode that never sleeps — "Persistent mode" keeps the coding agent working across sessions, aimed squarely at rivaling an always-on agent from SpaceX.
• Claude's status page shows elevated errors across multiple models this morning — ongoing as of writing; r/ClaudeAI already has a live discussion thread running.
• X leaks claim a Claude Opus 5.5 launch today — Anthropic hasn't confirmed anything — codename "claude-wafer-eap," rumored around 20% cheaper than Opus 5.

Alibaba's Apsara Bet: Chips, Cloud, Models, and Agents in One Stack

Alibaba opened its three-day Apsara Conference in Hangzhou by confirming Qwen 4 is in training, with Qwen 4.5 and Qwen 5 on the roadmap scaling to 5–10 trillion parameters. The company also showed off recursive self-improvement in production: Qwen3.8-Max ran 33 fully automated training cycles over a month, lifting its Artificial Analysis score from 40 to 45 with no human in the loop tuning it. On hardware, Alibaba's chip unit T-Head unveiled the Zhenwu V900 accelerator — 216GB of GPU memory, 1,200 GB/s inter-chip bandwidth, FP8/FP4 support, three times its predecessor's performance — with mass production slated for Q1 2027, alongside a roadmap for Yitian 720/730 CPUs in 2027. On the software side, a new three-layer cloud stack (AI Native Cloud, Agent Native Cloud, Context Engine) and an "AgentCore" platform target enterprise agent deployment, while "Qwen Intelligence" pushes agentic capability onto phone manufacturers' hardware directly. CEO Eddie Wu's framing was blunt: "Machine Thinking represents less than 3% of human thinking capacity," which is either humility or a very large sales pitch for everything else Alibaba announced today. The conference runs through Thursday, so more is likely coming. → Source

Xiaomi Ships a Genuinely Open Trillion-Parameter Model

Xiaomi open-sourced MiMo-V2.6 in two flavors — Pro (1.02T parameters) and Flash (309B) — plus a distilled 9B version small enough to run on a single high-end GPU. Both are natively omnimodal, handling text, image, video, and audio with up to a million tokens of context, and both are pitched at coding, computer-use, and long-horizon agent work rather than chat. Pro scored 46.32 on the Artificial Analysis Intelligence Index v4.3, currently the highest of any open-weight model on that board. The training numbers are unusually specific for an open release: 30 reinforcement-learning steps across roughly 750,000 trajectories pushed Flash's DeepSWE v1.1 score from 48.8 to 65.68 and Pro's from 58.4 to 72.57. Pricing undercuts most closed frontier models by a wide margin — Flash at $0.14/$0.28 per million input/output tokens, Pro at $0.435/$0.87 — and weights are already up on Hugging Face, ModelScope, and OpenRouter, with r/LocalLLaMA threads on the distilled Qwen-9B version within hours of release. Xiaomi's own marketing calls the target use case "Vibe World": robotic-arm control from video feeds and interactive 3D scene generation. Read the license before assuming "open" means "unrestricted," but on parameter count and price this is a real frontier-adjacent release, not a marketing exercise. → Source

OpenAI's Codex Is Learning Not to Stop

WIRED reported in late August that OpenAI is testing a "Persistent mode" for Codex, its coding agent, that lets it keep working across sessions until a user explicitly puts it to sleep — a break from every current mode, which stops after a fixed window whether or not the task is done. Code found in Codex's repository describes the agent proactively generating its own follow-up tasks, drawing on prior interactions and what it knows about the user to decide what to do next, and occasionally reaching out on its own initiative, though sparingly. It can't expand its own permissions, and anything touching systems outside the user's existing environment still needs explicit approval. OpenAI confirmed the feature is real and under internal testing but says there's no launch plan yet. The timing isn't a coincidence: The Information reports OpenAI is building agent features specifically to counter an always-on digital teammate that SpaceX has already shipped, one designed to sit inside a user's workflow indefinitely rather than being invoked task by task. Chinese-language social posts this week claim OpenAI will ship a branded version of this — under names like "Aeon" — alongside new GPT-6 tiers, but that specific branding hasn't shown up in any reporting I could verify. The underlying persistent-agent work has. → Source

Turn Off Claude Code's Prompt Suggestions to Cut Spend

A Reddit user instrumented their own Claude Code sessions ahead of a customer call and found that prompt suggestions — the greyed-out autocomplete text at the end of your input line — trigger a full cache read of your entire context just to guess your next message. Median cost: 91% of a normal prompt.

1. Run /config inside Claude Code, search for promptSuggestionEnabled, and set it to false
2. Or add "promptSuggestionEnabled": false directly to ~/.claude/settings.json
3. Or set CLAUDE_CODE_ENABLE_PROMPT_SUGGESTION=false in the "env" block of settings.json

Why it matters: on long-context sessions this can run up to 10% of your weekly usage limit for a feature you probably weren't relying on anyway.

🦞 TL;DR

The narrative today: Alibaba used Apsara to lay out a full-stack AI bet — chips, cloud, models, and agents, all in one keynote — while Xiaomi quietly shipped genuinely open trillion-parameter weights, and OpenAI keeps building agent features it insists it has no plans to launch.

My take: The Xiaomi release is the one worth your actual attention today. Alibaba's Apsara keynote is a strategy slide dressed up as news — real, but nothing ships until Q1 2027 at the earliest. MiMo-V2.6 is on Hugging Face right now, undercuts closed frontier pricing by an order of magnitude, and tops the open-weight leaderboard. That's the kind of announcement that changes what you build with this week, not next year.

What I'm watching: Whether the Claude Opus 5.5 rumors resolve today given the "Tuesday" leak, and whether the elevated-errors incident on Claude's status page is still open by tomorrow's briefing.

Stay informed. Stay curious.
