In March 2026, three LLM agents generated over 600,000 lines of code, ran 850 experiments, and helped secure a first-place finish in a Kaggle playground competition. Success in modern machine learning competitions is increasingly defined by how quickly you can generate, test, and iterate on ideas. LLM agents, combined with GPU acceleration, dramatically compress this loop. Historically… Source

GPT-5.5 launches via Codex and ChatGPT with strong coding performance; API access delayed pending safety review.

Meta is planning to layoff around 10 percent of employees in May, according to a memo from the company's chief people officer, Janelle Gale, published by Bloomberg. That means approximately 8,000 people will see their jobs cut. Meta will also be closing around 6,000 open roles, according to Gale. The cuts follow Meta's significant investments in AI, including spending huge sums to hire top talent and build data centers. The company forecast in January that it will spend $115 billion to $135 billion in capital expenditures in 2026 - a significant increase from its $72.22 billion in capital exp...

Sam Altman highlights GPT-5.5 improvements in token efficiency, latency, and new Codex features.

Anthropic's tightly controlled rollout of Claude Mythos has taken an awkward turn. After spending weeks insisting the AI model is so capable at cybersecurity that it is too dangerous to release publicly, it appears the model fell into the wrong hands anyway. According to Bloomberg, a "small group of unauthorized users" has had access to Mythos - whose existence was first revealed in a leak - since the day Anthropic announced plans to offer it to a select group of companies for testing. Anthropic says it is investigating. That's a rough look for a company that has built its brand on taking AI ...

OpenAI just announced its new GPT-5.5 model, which the company calls its "smartest and most intuitive to use model yet, and the next step toward a new way of getting work done on a computer." OpenAI just released GPT-5.4 last month, but says that the new GPT-5.5 "excels" at tasks like writing and debugging code, doing research online, making spreadsheets and documents, and doing that work across different tools. "Instead of carefully managing every step, you can give GPT-5.5 a messy, multi-part task and trust it to plan, use tools, check its work, navigate through ambiguity, and keep going," ...
