Anthropic advances agent infrastructure with a multi-agent harness emphasizing orchestration and "computer use" for complex software environments. Figma, GitHub, and Cursor launch design canvases with direct AI editing, showcasing tool-calling becoming product-native. Nous Research releases Hermes Agent v0.4.0 with 300+ PRs, adding OpenAI-compatible APIs and self-improving memory agents. Open agent ecosystems mature with AI2's MolmoWeb (4B and 8B models), GenReasoning's OpenReward platform offering 330+ RL environments and 4.5M+ tasks, and Zhipu's ZClawBench benchmark with 116 real-world agent tasks, highlighting progress toward standardized environment serving and benchmarkable agent tasks.

ARC-AGI-3 benchmark introduced by @arcprize and François Chollet resets the frontier for general agentic reasoning with humans solving 100% of tasks versus under 1% for current models, focusing on zero-preparation generalization and human-like learning efficiency. The scoring protocol sparked debate over its harsh efficiency-based metric compared to prior ARC versions and other benchmarks like NetHack. The community acknowledges the benchmark highlights weaknesses in current LLM agents in interactive, sparse-feedback environments. Concurrently, agent infrastructure advances with LangChain launching Fleet shareable skills for reusable domain knowledge, and Anthropic revealing Claude Code auto mode for classifier-mediated approval balancing autonomy and manual confirmation. Browser and coding agents are evolving into trainable systems beyond prompt wrappers, exemplified by BrowserBase and Prime Intellect collaboration.

OpenAI released GPT-5.4 mini and GPT-5.4 nano, their most capable small models optimized for coding, multimodal understanding, and subagents, featuring a 400k context window and over 2x speed compared to GPT-5 mini. The mini model approaches larger GPT-5.4 performance while using only 30% of Codex quota, becoming the default for many coding workflows. Pricing concerns and truthfulness tradeoffs were noted, with mixed third-party evaluations on reasoning and resistance to false premises. OpenAI also addressed behavior tuning issues in a recent update. Meanwhile, agent infrastructure is evolving with secure code execution and orchestration tools like LangChain's LangSmith Sandboxes and Open SWE, inspired by internal systems at Stripe, Ramp, and Coinbase. Subagents and secure execution are now key product features, with releases like Hermes Agent v0.3.0 showcasing plugin architectures, live Chrome control, and voice mode. Research on attention mechanisms, including Attention Residuals and vertical attention, is gaining traction.

MCP tools remain relevant for deterministic APIs despite ergonomic criticisms, with new web MCP support in Chrome v146 enabling continuous browsing agents. Persistent memory is emerging as a key differentiator for agents, with IBM improving task completion rates and multi-agent memory framed as a computer architecture challenge. Agent UX is evolving towards always-on, cross-device operation, exemplified by Perplexity Computer on iOS and Claude Code session management. Anthropic released Opus 4.6 1M context as default with no extra long-context API charges, achieving 78.3% on MRCR v2 at 1M tokens. Sparse attention optimizations like IndexCache in DeepSeek Sparse Attention yield significant speedups on large models with minimal code changes.

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.

NVIDIA’s Nemotron 3 Super is a 120B parameter / ~12B active open model featuring a hybrid Mamba-Transformer / SSM Latent MoE architecture and 1M context window, delivering up to 2.2x faster inference than GPT-OSS-120B in FP4 with strong throughput gains. It supports agentic workloads and is unusually open with weights, data, and infrastructure details released. The model scored 36 on the AA Intelligence Index, outperforming GPT-OSS-120B but behind Qwen3.5-122B-A10B. Community and infrastructure support from projects like vLLM, llama.cpp, Ollama, Together, Baseten, W&B Inference, LangChain, and Unsloth GGUFs was immediate. Key technical innovations include native multi-token prediction (MTP) and a significant KV-cache efficiency advantage.
On the product side, a shift towards persistent agent runtimes and orchestration layers is highlighted, with Andrej Karpathy advocating for a "bigger IDE" concept where agents replace files as the unit of work, enabling legible, forkable agentic organizations with real-time control. New launches fitting this vision include Perplexity’s Personal Computer, an always-on local/cloud hybrid running on Mac mini, and Computer for Enterprise orchestrating 20 specialized models and 400+ apps. Replit Agent 4 offers a collaborative, canvas-like workflow with parallel agents, while Base44 Superagents provide integrated solutions for nontechnical users. The engineering focus is increasingly on the orchestration harness rather than just the model.
