Is Muse Spark (Meta) Down?

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**

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** -- neither shipped with a public rate card

Xiaomi's MiMo-V2.5 family launched 2026-04-22 -- Pro (1T total / 42B active MoE, 1M context, native vision+audio reasoning), Multimodal base, TTS (3 sub-models: base, VoiceDesign, VoiceClone), and ASR (open-source, English + Chinese + major dialects). Full voice pipeline for the agent era. Extra-charge 1M-context tier removed at launch

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
