Six AI engineering signals from the last 24 hours: Codex hits 7M users after 10x growth in six months. Anthropic's tokenizer inflates costs versus competing models. A Claude API budget cap reportedly overran its stated limit by 7x. Apple's pla…

"We’re launching the GPT‑5.6 family of models for general availability following our limited preview⁠: our new flagship, Sol, alongside Terra, a balanced model for everyday work, and Luna, our most cost-efficient model. GPT‑5.6 delivers a step cha…

The main conclusions from analysis were: The Pareto frontier for coding tasks (i.e. best quality for a given cost) includes models from OpenAI, Anthropic, and open source. This means today, only a mix of tools can provide frontier performance. Op…

Anthropic filed a confidential S-1 with the SEC this week, moving toward a public listing that will put disclosure obligations and investor return expectations directly in tension with its safety-first positioning. The IPO filing lands as GitHub Copilo…

GPT-next solved an 80-year-old Erdős combinatorics conjecture for under $1,000 in compute. That single fact reframes everything else happening this week. The Erdős unit distance problem resisted human mathematicians since 1946. A frontier model closed …

An AWS user just stared down a $30,000 invoice after a Claude adventure on Bedrock with no guardrails catching it. Cost Anomaly Detection failed entirely, which matters because this is the exact tooling AWS markets as the safety net for runaway spend. …
