I. Large Language Models (LLM / Foundation Model)

1. OpenAI GPT-5.6 Luna Becomes Default Model for Free Users, ChatGPT Gets Epic Upgrade

• Summary: Effective immediately, GPT-5.6 Luna becomes the default model for ChatGPT Free and Go users, offering unlimited text chat. For the first time, free users get a "Think" button to invoke higher reasoning effort.
• Source: OpenAI Official Blog / Future Turing Weibo · 2026-08-07
• Editor's Comment: ChatGPT, used by 1 billion users weekly, receives its largest-ever free upgrade. OpenAI is using a free strategy to solidify its user moat.

2. OpenAI Launches Agent Plugins Open Standard, A Gift for GPT-5's First Anniversary

• Summary: On the first anniversary of GPT-5's launch, OpenAI released Agent Plugins—a plugin packaging standard for AI agents. Amazon, Cursor, Microsoft, Vercel, and others have joined the steering committee.
• Source: IT Home / OpenAI Official Website · 2026-08-07
• Editor's Comment: From ChatGPT Plugins to Agent Plugins, OpenAI has finally turned the plugin standard into public infrastructure with open governance.

3. Meta Refuses to Sign EU AI Code of Conduct, Becoming Only Major AI Vendor Without Signature

• Summary: With EU AI Act enforcement starting August 2, over 180 organizations signed the GPAI Code of Conduct. Meta is the only Tier 1 model provider refusing to sign, citing "legal uncertainty."
• Source: AI Policy Desk · 2026-08-07
• Editor's Comment: Llama 4 has already excluded EU users. Meta is fighting regulation with "geo-fencing," but the fine cap of €15 million or 3% of global revenue cannot be ignored.

4. xAI Signs Only Safety Chapter of EU AI Code of Conduct, Missing Transparency and Copyright Sections

• Summary: xAI signed the safety and security chapters of the Code of Conduct but refused to sign the transparency and copyright chapters. Grok lacks the "presumption of compliance" protection regarding training data transparency and copyright compliance.
• Source: AI Policy Desk · 2026-08-07
• Editor's Comment: Signing halfway is more subtle than not signing at all—safety is compliant, but data provenance and copyright remain hanging in the air.

5. GPT-5.6 Sol Accuracy Improves Significantly: Error Rates in Finance/Medical/Legal Drop by 68%

• Summary: In tests across finance, healthcare, and legal fields, GPT-5.6 Sol reduced factual error rates by 68% compared to GPT-5.5 Instant, while Luna reduced them by 62%.
• Source: OpenAI Official / Future Turing · 2026-08-07
• Editor's Comment: Accuracy is the hidden focus of this update. OpenAI has finally made "making fewer mistakes" a core selling point rather than just "more features."

6. NVIDIA Releases Open-Source Cosmos 3 Physical AI Foundation Model Family

• Summary: NVIDIA released Cosmos 3, an open-source world foundation model family, including Super (64B), Nano (16B), and Edge (4B) variants. It ranks first in multiple benchmarks such as Artificial Analysis, PAI-Bench, and RoboLab.

6. Lemma Raises $2.3 Million Pre-Seed, Targeting Silent Failures of AI Agents in Production

• Summary: Lemma targets a very difficult class of problems: silent failures of AI Agents in production environments, building monitoring infrastructure to capture these anomalies.
• Source: Unite.AI · 2026-08-07
• Editor's Comment: Deploying an Agent is easy; keeping it error-free is hard; detecting errors promptly when they occur is even harder—Lemma is cutting into the final link in Agent operations.

7. Yellow.ai Goes Public via SPAC, Enterprise AI Agent Companies Take M&A Route

• Summary: Enterprise AI Agent company Yellow.ai went public through a merger with Bluerock Acquisition Corp, taking the SPAC route to list on Nasdaq.
