Moshi-Face: Full-Duplex Dialogue with Facial Generation

Moshi-Face is the first full-duplex spoken dialogue model that jointly processes audio and facial input, generating both speech and synchronized facial motion. It uses a VQ-VAE face codec to encode and reconstruct 3D head meshes from facial videos into discrete face tokens, and a Face Transformer module to generate these tokens non-autoregressively for real-time audiovisual output. Experiments show Moshi-Face achieves audiovisual alignment with low latency while maintaining original dialogue quality.

CFAgentBench: Benchmark for Autonomous Construction-Finance Agents

CFAgentBench introduces a reproducible, self-hostable environment with 1,014 machine-gradeable tasks across eight domains, grounded in real-world sources. It features 40 oracle-validated tasks with executable evaluators that assess functional correctness via state diffs and output regexes, including a money-movement guard requiring human approval for payments. A key finding is that top agents lose 43% of successes when repeating tasks under temperature-0 decoding, indicating single-attempt performance does not reflect real-world deployability.

Nous: A Predictive World Model for Long-Term Agent Memory

Nous introduces a memory architecture based on prediction rather than storage, using categorical probability distributions to model world knowledge. Evaluated on LoCoMo with GPT-4o-mini, it achieves F1 scores of 63.50 (single-hop), 55.32 (multi-hop), -58.57 (temporal), and 62.50 (open-domain), outperforming A-MEM in three categories and BeliefMem in all, though evaluation differences limit full comparability.

Measuring Genuine Emergent Consensus in LLM Agent Societies

A new metric, coupling gain gamma, measures how agents adjust opinions when neighbors' views are perturbed. It reveals that frontier LLMs do not spontaneously polarize, and a diagnostic of final versus initial opinion shows that claimed emergent consensus in prior work involves model artifacts. Valid consensus emerges only when group-level, modality-matched coupling is considered, not single-neighbour interactions.

MCP servers consume context window via tool definitions

Each MCP server dumps its full tool list into the model's context before any prompt, using up to 24,000 tokens for 62 tools. A local gateway implementing lazy discovery reduces tool-definition overhead by 97%, cutting token usage from ~24k to ~660 per request, with 90% fewer total tokens over a task, without affecting task success rate.

Same model, same prompt, 4 different agents produce varied code quality

A self-hosted Qwen3.6-27B model with identical prompt and hardware generated four different HTML/JavaScript solar system simulations. The agent scaffolding significantly influenced output: opencode produced clean, stable code with accurate physics; pi showed robustness and coordinate consistency; hermes offered visually appealing but physically flawed results; qwen code generated minimal, crude code. The results highlight how agent design shapes code quality, correctness, and stability despite shared model and prompt.
