Agents

openJiuwen proposed MANGO, a multi-agent flow-network framework that combines reinforcement learning, textual gradients, and a Skip-k mechanism; using GPT-4o-mini, it reports a 12.8% accuracy gain over MaAS on MATH500 and a 5.1% F1 gain over AFlow on DROP.

OpenAI outlined its third-phase plan with three goals: build an automated AI researcher, accelerate the economy, and give every person a personal AGI. Sam Altman and Jakub Pachocki said OpenAI internally believes AI systems may perform a significant fraction of its research by March 2028, while alignment, safety standards, and international coordination remain explicit conditions.

Hugging Face announced broader OpenEnv access, coordinated by a committee from Meta-PyTorch, Reflection, and Unsloth; the project provides Gymnasium-style APIs and first-class MCP support for terminal and browser agent environments.

OpenAI is preparing ChatGPT’s largest redesign since its 2022 launch, shifting it toward an agent platform that integrates Codex, image generation, Canva, and Booking, with web and mobile rollout planned in the coming weeks. ChatGPT has 900 million weekly active users, 50 million paid users, and $2 billion in monthly revenue, but the post says it remains unprofitable.

Hokkaido farmer Hiroki Tomiyasu uses ChatGPT and Codex for 8 farm tasks, including broccoli disease recognition, NDVI monitoring, ESP32 greenhouse control, LINE chatbots, sowing-count tracking, RTK-GPS steering study, and an Airtable farm database.

UIUC and Chroma released Harness-1, a 20B-parameter retrieval subagent trained with reinforcement learning inside a stateful search harness, reporting 0.730 average curated recall across 8 benchmarks, 11.4 percentage points above the next-best open-source subagent and behind only Opus-4.6.

Jack Clark said Claude now produces 80% of Anthropic’s merged code and projected the share may reach 100% within two years; the article also says Anthropic engineers merged 8 times more code per person per day in Q2 2026 than in 2024.

FusionRoute proposes a token-level multi-LLM collaboration method that freezes expert models and trains a lightweight router to select an expert for each token while merging router logits with expert logits. The paper evaluates it on GSM8K, MATH-500, HumanEval, MBPP, IfEval, and 500 PerfectBlend prompts.

JD open-sourced JoyAI-Echo, a long audio-video generation framework for 5-minute consistent videos, using cross-modal memory, DMD post-training for about 7.5x faster inference, and real-time upscaling from 720P to 1K or 2K output.

Coinbase, Lindy, Harvey, and Cursor shifted workloads to cheaper models; Harvey reported Kimi 2.6 reached a 15% all-pass rate on Legal Agent Benchmark, versus Opus at 14%, with 100 tasks costing $84 versus $954.

The article reverse-engineers Claude Design from Anthropic’s open-source Design plugin and describes a six-layer structure; the snippet only discloses mechanisms such as workflow decomposition, aesthetic injection, evaluation transfer, and connector abstraction.

OpenAI introduced Lockdown Mode for ChatGPT, disabling live web browsing, web image retrieval and display, deep research, and agent mode for self-serve ChatGPT Business accounts and eligible personal accounts.

Thousand Token Wood v2 uses four small models from different labs to drive agents in a financial simulation game, with vLLM 0.22.1’s CUDA toolkit dependency identified as the main serving friction, while a fine-tuned 0.5B Qwen reached 0% self-trading and 100% valid quotes.

GitHub released the open-source Spec Kit, shifting AI coding from direct implementation to product specifications, gap clarification, technical planning, task breakdown, and agent execution, with support for 30+ agent integrations including Copilot, Claude Code, Codex, Gemini, Cursor, and Qwen, and 109K+ GitHub stars.

The author compared five coding-agent setups on a Laravel 12 + Livewire Playwright E2E task; Claude Opus 4.7 with 1M context produced 203 tests, while the strongest local OpenCode arm on a 24GB RTX 4090 produced 140 tests, compacted context four times, and needed seven manual nudges.

The author retired an OpenClaw AI assistant after more than one month of use; the post says it required self-hosting, API setup, and keeping one home computer running 24 hours a day.

Anthropic is using Snorkel’s Marlin project to recruit about 1,000 software engineers who review Claude Code outputs for $280 per task, with a workflow covering GitHub repository pull requests, A/B comparisons of two generated code versions, and scoring for correctness, security, reliability, and maintainability.

Lion Rock AI Lab won first place in the ICRA 2026 LeHome Challenge real-robot final, using LiOS to connect training, deployment, trajectory sampling, and Real2Sim teleoperation in one data iteration loop.

Princeton researchers released Goedel-Architect, an agent framework for Lean formal theorem proving. Using DeepSeek-V4-Flash, it reached 75.6% pass@1 on PutnamBench, with $294 in API cost for 672 problems, compared with Hilbert’s 70.0% and about $170,000 cost.

JD open-sourced JoyAI-Echo, a long audio-video generation framework that supports up to 5 minutes of cross-shot audiovisual consistency, local repainting, 8-step DMD distillation, and output up to 1472×2560 resolution.
