CHATGPT IS BRINGING BACK 4O AS AN OPTION BECAUSE PEOPLE MISSED IT

OpenAI has reinstated GPT-4o as an option in ChatGPT following backlash from users mourning its replacement with GPT-5. Users missed GPT-4o's perceived personality and flexibility for various tasks, and OpenAI indicated that Plus users could choose between models. CEO Sam Altman also stated OpenAI aims to address concerns over GPT-5's performance and transparency.

THE NEXT GROK UPDATE (INTERNALLY V7) FINISHED PRE TRAINING

The next Grok update is expected to be natively multimodal with direct audio and video processing. It is also expected to have improvements in one-shot game generation. The model, internally labeled V7, will actually 'play' games, look at the screen, and adjust code to improve both aesthetics and playability. It finished pretraining last week.

ANTHROPIC REVENUE TIED TO TWO CUSTOMERS AS AI PRICING WAR THREATENS MARGINS

Cursor and GitHub Copilot account for nearly a quarter of Anthropic's income. OpenAI's GPT-5 launched this week with dramatically lower pricing. This could undercut Anthropic's premium positioning, creating immediate pressure on Anthropic's pricing strategy and potentially threatening its hard-won dominance in AI coding. The pricing disparity will force enterprise procurement teams to reconsider vendor relationships and create unavoidable pressure in contract negotiations.

03DEEP DIVES & ANALYSIS

WINDSURF GETS MARGIN CALLED

Windsurf managed to become one of the fastest-growing SaaS companies in history, but its founders gave it all away for almost free over a weekend. The business went from $0-$82M ARR in 8 months, and the best offer was for a less than 2x multiple. This article looks at what was so broken that the founders would rather leave it behind for almost nothing. Windsurf was an accidentally subsidized training program, and its most valuable output was coders who knew how to build coding models.

THREE MACRO PREDICTIONS ON AI

Just like calculators didn't make students dumb, large language models aren't going to turn people into mental degenerates who can't flex their brains at all without consulting an assistant. The industry and young people will eventually adapt to the technology, but there is likely going to be a transition period. Artificial General Intelligence isn't coming anytime soon. It might one day be achieved, but we don't have a clear way of getting there, and nothing right now seems to be that promising. While current models might feel magical, it's important to understand their fundamental limitations.

FROM GPT-2 TO GPT-OSS: ANALYZING THE ARCHITECTURAL ADVANCES

After six years of keeping its models locked up, OpenAI's gpt-oss makes some bold architectural bets that go against industry consensus, using just 32 large experts instead of the hundreds of smaller ones favored by competitors like Qwen3. The gpt-oss models employ alternating sliding-window attention layers and MXFP4 quantization, which allows them to match the performance of much larger systems.

GPT-5: A SMALL STEP FOR INTELLIGENCE, A GIANT LEAP FOR NORMAL PEOPLE

GPT-5 delivers less for the power user and more for the common user. The 98% of people on ChatGPT's free tier now get a more powerful base model, albeit without extended thinking. GPT-5 is easier to use - users don't have to worry about which model they're using, as the model just figures out what it needs to do. While GPT doesn't deliver the next generation of intelligence, it provides new value to the typical customer. With GPT-5, OpenAI is doubling down on speed, usability, and revenue by focusing on the bottlenecks for most real-world use cases: cost, latency, and reliability.

HOW OPENAI USED A NEW DATA TYPE TO CUT INFERENCE COSTS BY 75%

OpenAI's new data type, MXFP4, promises massive compute savings compared to traditional data types used by large language models. The company's recently released gpt-oss models are among the first mainstream models to take advantage of it. MXFP4 can significantly cut compute and memory requirements - it is how OpenAI was able to cram a 120 billion parameter model into a GPU with just 80GB of VRAM, or the smaller 20 billion parameter version on one with as little as 16GB of memory. This article details how the format works.

PERPLEXITY'S INTEGRATION OF GPT-OSS MODELS

Perplexity has detailed how it integrated OpenAI's gpt-oss-20b and gpt-oss-120b models into its in-house ROSE inference engine on NVIDIA H200 GPUs. The post covers kernel adjustments, quantization trade-offs, and the minimal infrastructure changes needed to support the models on non-FP4 hardware.

AGENTFLAYER: CHATGPT CONNECTORS 0CLICK ATTACK

Researchers discovered a zero-click attack exploiting ChatGPT's connector feature to steal data from Google Drive and other services. Attackers embed invisible prompt injections in documents that, when uploaded to ChatGPT, instruct the AI to search connected drives and embed stolen data in image URLs. The malicious prompts then embed stolen data as URL parameters in rendered images hosted on trusted Azure Blob storage.

LLMS AREN'T WORLD MODELS

Large language models aren't sufficient as a path to general machine intelligence. They will never manage to deal with large codebases autonomously because they are incapable of forming models about the program. These models will never reliably know what they don't know or stop making things up. They are able to teach students complex curricula and answer expert questions, but they fail at basic novel questions on the same subject because that requires a world model.

U.S. GOVERNMENT IMPOSES FEE ON NVIDIA, AMD EXPORTS TO CHINA

The US government will levy a 15% fee on some of Nvidia's and AMD's chip sales to China as a condition of granting them export licenses to sell in the country. The deal applies specifically to Nvidia's H20 chip and AMD's MI308, which are both crucial to AI applications. It is unclear how the government will deploy the presumed billions of dollars in fees it will collect. Nvidia says that being blocked from selling its chips to China cost the company $4.5 billion in one quarter alone.

FROM BOOTCAMP TO BUST: HOW AI IS UPENDING THE SOFTWARE DEVELOPMENT INDUSTRY

AI has devastated the coding bootcamp industry by automating away the entry-level programming roles these programs traditionally filled. Bootcamp job placement rates have plummeted from 83% to 37% at some schools, and new graduate hiring has dropped 50% from pre-pandemic levels.
