Is MiMo (Xiaomi) Down?

Meta's frontier model line from its Superintelligence Lab -- Muse Spark 1.1 (2026-07-09) adds substantially better coding, 1M-token multi-agent orchestration, and Meta's first paid developer API (Meta Model API, public preview)

**Life Sciences Verification Program opened 2026-09-17** -- verified life-science teams get Mythos 5.1, Opus 5 and Sonnet 5 with the biology safeguards relaxed (Standard Use grants renewed yearly; High-risk Use grants per project every six months, Opus 5 and Sonnet 5 today, Mythos still US-government-gated), on top of the 2026-08-27 Claude team plan for scientists (10,000 seats, standard free, premium $15/mo). Anthropic's flagship LLM family. **Claude Opus 5 launched 2026-07-24** and is now the default model on Claude Max and the strongest model on Claude Pro -- same $5/$25 per 1M as Opus 4.8, but Anthropic says it lands within 0.5% of Fable 5 on CursorBench at half the cost. **Sonnet 5's $2/$10 per 1M is now permanent** -- Anthropic cancelled the 2026-09-01 rise to $3/$15 and made the launch rate standard -- and it stays the default on Free/Pro. **Claude Fable 5.1 and Mythos 5.1 launched 2026-09-01** and now top the range -- same $10/$50 per 1M as Fable 5, with the saving delivered entirely through a 4x cheaper cache read ($1 -> $0.25/MTok), so it is 25-45% cheaper only if your workload reuses cached context. **From 2026-08-14 future Claude models watermark their text output globally** (SynthID-Text; no extra tokens, no price or speed change, no identifying information -- detector API not shipped yet), and the **legacy Workbench plus the experimental prompt-tools APIs retired 2026-08-17**

**Gemini 3.8 Live and 3.8 Live Extended Thinking launched 2026-09-15** -- native speech-to-speech models in the Gemini API at $0.005/min audio in and $0.018/min audio out (audio-in a tenth of GPT-Live-1's $0.05/min voice layer, and on the same price row as the older 3.1 Flash Live), with Extended Thinking taking the #1 spot on Artificial Analysis' Speech to Speech Quality Index (82.6) and rolling into Gemini Live, Search Live and Workspace Docs/Gmail/Keep. **Gemini app for Windows shipped 2026-09-10** (Alt+Space overlay, Google-app connectors, Gemini Spark on desktop) and the Sept 9 AI-plan refresh added Google Pics and Sheets canvas for AI Pro/Ultra plus Gemini Spark hooks into Chrome and Google Photos. Google's LLM with deep Google Workspace integration, 2M token context window, and native code execution -- **Gemini 3.8 Flash launched 2026-09-02** -- the third Flash release in six weeks -- at the SAME $0.75/$3.75 per 1M intro rate as 3.7 Flash and, critically, **on the same 2026-12-31 expiry** (then $1.50/$7.50), so the discount window did not reset. HLE-Verified 54.9%; Google warns it uses more tokens per task because it 'works harder', so cost per task can rise at an unchanged rate. **Gemini 3.8 Flash Cyber** is trusted-defenders-only via the new **Fairwind Program**. Gemini 3.7 Flash (2026-08-13) remains fully supported for efficiency-first work. Gemini 3.5 Pro STILL delayed and partner-testing-only (Bloomberg, 7/16 -- coding shortfalls, no ship date), so Flash keeps shipping while the Pro line stalls. Gemini 4 pre-training underway. **Two new models in Aug 2026: Gemini 3.5 Transcribe (2026-08-26) speech-to-text and Gemini Omni 1.1 Flash (2026-08-27) production video with 40s scene extension, start/end frames and 4K** -- Transcribe's rate card has since appeared (about $0.005/min blended, verified 9/17); Omni 1.1 Flash's still has not

Tencent's Hy3 reached GA 2026-07-06 (upgraded from the April preview) -- 295B total / 21B active MoE, 256K context, now Apache 2.0 open weights on HuggingFace + ModelScope with the EU/UK/South Korea restriction lifted. ~90% agent-task completion on Tencent's internal apps; API via Tencent Cloud TokenHub. Integrated into Yuanbao, WeChat, QQ

SpaceXAI's irreverent chatbot with a direct line to X/Twitter -- and now **Grok 4.6 (launched 2026-08-12)**, focused on long-running agents and interactive/visual work, at the same $2/$6 per 1M as Grok 4.5 (fast variant 2x). xAI says it matches GPT-5.6 Sol on the AA Intelligence Index (61), though Sol still leads it on DeepSWE and Terminal-Bench. **Grok Bot** (8/11, early beta) adds always-on agents with their own cloud computer. **Grok 4.6 reached GitHub Copilot on 2026-08-14** across all five paid Copilot SKUs (off by default for orgs), adding to its day-one Cursor availability. Grok 4.3 remains the value tier at $1.25/$2.50
