Harnesses, agent infrastructure, and the MCP protocol are central themes, with emphasis on how harnesses, sandboxes, filesystem access, skills, memory, and observability shape agent UI/UX and runtime environments. Despite jokes about MCP's demise, it remains vital in production, notably used internally by Uber and supported by Anthropic. The coding-agent stack is evolving with CursorBench combining offline and online metrics to evaluate models on intelligence and efficiency, where GPT-5.4 leads in correctness and token efficiency. Agent-assisted development is splitting between automation-heavy workflows and "stay-in-the-loop" tooling, with OpenAI advancing Codex Automations featuring worktree vs. branch choices and UI customization. The open agent platform Hermes Agent v0.2.0 introduces full MCP client support, ACP server for editors, and expanded provider integrations including OpenAI OAuth.

Yann LeCun predicts a shift to AR interfaces with AI assistants in 10-15 years, moving away from smartphones. The Dolphin-2.9 model based on Llama-3 was released, improving quality issues. PixArt Sigma, a 0.6B parameter model, achieves Stable Diffusion 3.0 level performance with complete prompt adherence and local usability. Research shows transformers can use meaningless filler tokens for algorithmic tasks with dense supervision. AI-generated restaurant reviews can pass the Turing test, fooling humans and AI detectors. Uber uses graph algorithms and learned embeddings for ETA prediction. Coca-Cola and Microsoft announced a 5-year AI partnership to accelerate cloud and generative AI initiatives. The Llama-3 70B model can run on a single 4GB GPU using AirLLM optimization without quantization but is slow. Mistral.rs is introduced as a fast LLM inference platform with quantization and OpenAI API compatibility. Only 5% of LLMs make it from prototype to production due to challenges, especially in enterprise. EXL2 and GGUF quantization methods for Llama models show similar perplexity vs model size, with Llama-3 and Llama-2 degrading more under quantization compared to full precision.
