MichiAI hits sub-100ms with promptable ASR

MichiAI is a 530M parameter full-duplex speech LLM that introduces natural language prompt engineering to ASR. By unifying a modified Whisper encoder with a SmolLM backbone, it enables real-time transcription primed with semantic categories and conversation history, achieving ~75ms latency for natural voice agents.

// ANALYSIS

MichiAI’s "listen-head" architecture replaces the serial ASR-LLM-TTS pipeline with a unified multimodal approach that understands input audio. The system moves beyond primitive static word boosting to support semantic category priming and structural expectations via natural language. A real-time feedback loop between audio embeddings and text tokens enables context-based error correction, while a self-prompting mechanism uses conversation history to prioritize expected phonemes and achieve ~75ms latency.

Moonshot AI has officially released Kimi K2.7-Code, an open-weights coding model optimized for long-horizon software engineering and cost-efficient agentic reasoning.

Moonshot AI has officially released Kimi K2.7-Code, an open-weights Mixture-of-Experts coding model featuring 1 trillion parameters and a 256K context window. Optimized for long-horizon software engineering tasks like codebase-wide refactoring and debugging, the model achieves a 30% reduction in reasoning-token usage compared to its predecessor. Kimi K2.7-Code supports multimodal inputs, runs in a dedicated reasoning-heavy thinking mode, and is available for developers via Hugging Face, Ollama, and the Kimi API.

Seedance 2.0 workflow animates consistent characters

AI creator Aimi Kōda shared a step-by-step generative AI workflow titled "Surf on the Clouds" that coordinates Midjourney, GPT Image 2, and Seedance 2.0. The tutorial explains how to generate a stylized character in Midjourney, build a structured 16:9 character identity sheet using GPT Image 2, and animate the assets using Seedance 2.0 to maintain visual and narrative consistency across scenes.

Claude Fable 5 overshadows Claude Opus 4.8

The rapid succession of Anthropic's model releases has left Claude Opus 4.8—which debuted just two weeks ago as a major frontier model—largely forgotten in the wake of Claude Fable 5. Fable 5's introduction as the first generally available 'Mythos-class' model has generated massive hype due to its superior score of 80.3% on SWE-bench Pro and impressive multi-step autonomous planning, completely shifting the AI community's focus and discussions away from the incremental updates of Opus 4.8.
