Xiaomi open-sourced the world's top open model, a 1 trillion parameter beast that's completely free, VoiceStudio lets you clone voices, dub videos, and make audiobooks entirely free on your own computer, and Anthropic released Claude Opus 5.5, matching its top Fable model for about 40% less. And that's not all, here's everything in AI this week:
Tencent has released Hy Image 3.5 Preview, its most capable image model so far, built for multi-turn generation and editing rather than one-shot images. In Tencent's own designer tests it edges past Google's Nano Banana Pro, and it undercuts Google's pricing by a wide margin.
Multi-Turn Editing: Generate an image, then keep refining it across turns, changing background, lighting, or composition one step at a time, with output up to 4K.
Beats Nano Banana Pro: In blind tests by hundreds of Tencent's own designers, it scored on par with ByteDance's Seedream 5.0 Pro and slightly ahead of Google's Nano Banana Pro and Alibaba's Qwen-Image-3.0 Pro.
Fraction of the Cost: At about $0.024 per image on Tencent's international API, it runs roughly 5x cheaper than Nano Banana Pro.

Runs on Your Phone: A mobile-first personal agent that does tasks (browsing, running code, handling files, tracking goals) instead of just answering questions.
Keeps Going When Closed: Goals and delegated jobs keep advancing on the server even after you close the app.
Bring Your Own Model: MIT-licensed and model-agnostic, with a separate gatekeeper that asks before any action you cannot undo.

Anthropic has released Claude Opus 5.5, the first model in its Claude 5.5 family. It performs at the level of Anthropic's top Fable 5.1 model on most work, while costing about 40% less to run than Opus 5.
Fable-Level Performance: Matches Claude Fable 5.1 on most tasks and leads Anthropic's lineup on coding, agents, and knowledge work.
Cheaper to Run: Uses fewer tokens per task and is priced 20% below Opus 5, which nets out to roughly 40% lower cost on typical workloads.
Faster Output: Generates output more than 30% faster than Opus 5, with a fast mode up to 2.5x speed in Claude Code and the Claude Platform.
