• Ai daily

Grok 4.5 Officially Released by xAI and Cursor xAI in collaboration with Cursor has released Grok 4.5 — a mixture-of-experts model trained on trillions of tokens of data from Cursor and SpaceX. This is the most intelligent model to date from xAI, capable of handling complex programming tasks, data science, finance, and law. On Hacker News, this post reached 401 points. With a price of $2/$6 for input/output, it is considered to be four times more cost-effective than Claude 3 Opus.

AI Daily Newsletter: Microsoft Copilot Ditches GPT for In-House Model and Mind-Reading Tool Claude

📰 Microsoft: Copilot Switches to In-House Models to Optimize Costs In an effort to cut down the massive operating costs of its AI system, Microsoft is replacing high-end language models from OpenAI (such as GPT-4o, GPT-4 Turbo) and Anthropic (Claude 3.5 Sonnet) with smaller models (SLMs) developed in-house, including the MAI line (such as MAI-1) and the improved Prometheus model. This transition is taking place quietly across popular Office products like Outlook, Excel, and Word, where the system has processed tens of thousands of queries each week through the new model.

🧠 GLM 5.2 Initiates the Era of Margin Collapse for AI Inference Zhipu AI releases GLM 5.2 – the first open-weight model considered a true competitor to Claude Opus and GPT for agentic tasks, but at only 15-20% of the inference cost. Concurrently, they launch ZCode, a coding agent platform directly competing with Claude Code and OpenAI Codex, offering a free 5-day trial. An analysis by Martin Alderson calls this the “beginning of the AI margin collapse” as open-weight models have caught up with closed-source models in terms of agentic work quality.

• Ai daily

🔴 Zuckerberg Admits AI Agents Are Slower Than Expected Mark Zuckerberg recently held an internal town hall meeting at Meta, acknowledging that AI agents are not developing as quickly as he had hoped. Despite plans to spend up to $145B in 2026 and 8,000 layoffs, Meta’s agentic AI development is falling behind schedule. He stated that “replacing people with AI” is much harder than initially imagined. This is a notable signal from one of the companies currently investing the most in AI.

AI Daily Newsletter: Mistral Launches Math Problem Solving Model and Anthropic Develops Medicines Autonomously

• Ai daily

🧮 Mistral Releases Leanstral 1.5 - A Formal Verification Model, Apache-2.0 Mistral AI has released Leanstral 1.5, a language model specializing in formal verification and proof in Lean 4. The model has 119B parameters in total but only 6B active (MoE), and is fully open-sourced under the Apache-2.0 license. Leanstral 1.5 achieves state-of-the-art results on miniF2F (saturate), solves 587/672 PutnamBench problems, and reaches 87% on FATE-H. Notably, the model discovered 5 previously unknown bugs in 57 open-source codebases tested. Mistral also provides a free API for this model.

AI Daily Newsletter: Anthropic Creates Its Own Medication and Students Receive Lower Test Scores Due to AI Use

• Ai daily

🧬 Anthropic Develops Its Own Medicines, Showing AI is Not Just a Chatbot Anthropic has announced that it will develop its own medicines for diseases that Big Pharma has overlooked due to lack of profitability. At the launch event of Claude Science (an AI workspace for researchers), Anthropic clarified that this timeline aims to support its non-profit mission and help them better understand how AI can be applied in science.

AI Daily Newsletter: Microsoft Invests 2.5 Billion USD in AI Deployment and OpenAI Wants to Donate Shares

🔥 1. Microsoft Launches Frontier Company — $2.5 Billion, 6,000 Engineers to Deploy AI Microsoft has officially established Microsoft Frontier Company, a new business unit with a $2.5 billion commitment and 6,000 technical experts, focusing on deploying AI for businesses. Unlike AWS’s ($1B) Forward-Deployed Engineer model, Microsoft calls this the largest “outcome-driven engineering” organization in the industry. Initial partners include the London Stock Exchange Group, Unilever, and Land O’Lakes.

AI Daily Newsletter: Together AI Raises $800 Million in Funding and Ford Rehires Veteran Engineers

🔥 1. Together AI Successfully Raises $800M, Valued at $8.3 Billion Together AI, a neocloud platform specializing in providing infrastructure for AI training and inference, has just concluded an $800M funding round, raising the company’s valuation to $8.3B. This is a signal that the demand for specialized AI cloud infrastructure is still booming, despite the cost-cutting wave in other areas.

AI Daily Newsletter: Claude Sonnet 5 Launches and AI Chip Etched Valued at 5 Billion USD

🔥 1. Anthropic Launches Claude Sonnet 5 — Cheaper, Stronger, Focus on AI Agent Sonnet 5 is Anthropic’s new mid-size upgrade, specifically designed to run AI agents at a lower cost. For just $2/M input token (reduced to $3 after August), this model achieves 63.2% on the agentic coding benchmark — nearly equal to Opus 4.8 (69.2%) while being significantly cheaper. As of today, Sonnet 5 becomes the default model for both Free and Pro plans. Anthropic is proving that agentic capability has become the baseline — the game is now about price and reliability.

AI Daily Newsletter: Claude Code Refutes Doctors and GLM 5.2 Surpasses Claude in Security

🔥 1. GLM 5.2 surpasses Claude for the first time in security benchmark Zhipu AI launched GLM 5.2 — a 750B parameter MoE model (40B active), MIT license, 1M token context — and it defeated Claude Code by 7 F1 points in the IDOR vulnerability detection task on Semgrep’s benchmark. The cost is only ~$0.17 per vulnerability found, 6 times cheaper than frontier models. This is the first time an open-weight model on a prompt surpasses a commercial coding agent in a security reasoning-heavy task.
