A production AI assistant requires a systems-level architecture beyond a single LLM invocation, splitting responsibilities into five layers: LLM, Memory, Tooling, Routing, and Observability. OpenAI and Anthropic define a…
Anthropic surpassed OpenAI to become the world's most valuable AI startup at a $965 billion valuation, driven by enterprise adoption of Claude Code. The proliferation of AI coding agents continued with new open-source to…
AI newsletter author Zvi Mowshowitz reports that OpenAI's upcoming Astra model uses a technique called recurrent depth, which shifts thinking outside the Chain of Thought, raising interpretability concerns. Meanwhile, th…
A new technical reference documents that AI model APIs, including Anthropic, OpenAI, and vLLM, return HTTP 200 with well-formed bodies when generation hits the max output token ceiling, making truncation indistinguishabl…
Ctxdiff, a new open-source debugger for LLM agents' context windows, lets developers see exactly what an AI model saw turn by turn, block by block, and identify the character that broke a prompt cache. The local-first to…
Anthropic's Claude Code team members Cat Wu and Thariq Shihipar said during a fireside chat at the AI Engineer World's Fair that coding agents have shifted engineering from months-long planning cycles to one-week build t…
Anthropic announced higher rate limits on the Claude API, including increased monthly spend caps across usage tiers—Start ($500), Build ($1,000), and Scale ($200,000)—and clarified that only uncached input tokens count t…
OpenAI CEO Sam Altman told staff on June 24 that GPT 5.6 will first be released as a limited preview to a small group of partners because the federal government asked OpenAI to stagger the rollout, according to The Infor…
Anthropic co-founder Ben Mann estimated a 5-10% chance of successfully aligning AI, prompting a framework for evaluating existential risk from frontier AI systems. The framework urges developers and regulators to assess …
A developer guide outlines 11 stages to build a self-running Claude assistant, progressing from a basic chat prompt to a cron-scheduled system that classifies emails, calls tools, and runs autonomously. The guide emphasi…
The Trump administration imposed export controls on Anthropic's new AI model, Fable, forcing it offline due to a security vulnerability. The move, which blocks foreign nationals from accessing the model, marks a shift fr…
Anthropic launched Claude Fable 5 on June 9, 2026, but the US government issued an export control directive on June 12 that forced the company to pull the model globally, including for US users and employees with foreign…
Anthropic published research on recursive self-improvement (RSI) while OpenAI's ChatGPT crossed 1 billion monthly active users five months behind schedule and announced improved memory features. NVIDIA released the open-…
Anthropic CEO Dario Amodei stated in a Davos interview that the world is not prepared for the magnitude of artificial intelligence's impact, describing the technology as following a "Moore's law for intelligence" that wi…
Anthropic released Claude Opus 5.5, the first model in its new Claude 5.5 family, which the company says performs at the level of Claude Fable 5.1 for most tasks while costing 40% less to run than Opus 5 and running abou…
A new npm package called 190proof provides a unified interface for calling models from OpenAI, Anthropic, Google, Groq, OpenRouter, and AWS Bedrock through a single `provider:model-id` string format. The package handles …
A new benchmark testing eight headless coding-agent CLIs on a single Python task found that seven of eight agents passed on both runs, but list prices per run varied 18-fold, from $0.0165 (DeepSeek V4 Flash off-peak) to …
A new ledger documenting model aliases and retirements in 2026 lists 19 floating aliases and 89 retirement rows across ten vendor groups, with notice periods ranging from 39 to 184 days. The dataset, as of 22 August 2026…
A new measurement study of prompt cache keepalive economics across Anthropic, OpenAI, Gemini, and DeepSeek finds that the common practice of pinging every 30 seconds costs 8x more than necessary, and at a ten-minute paus…
A developer's guide details how to run Anthropic's Claude Code CLI for free using third-party API proxy services AgentRouter and HCNSEC. The guide provides step-by-step instructions for installation, configuration, and t…
