Claude Code có thể tự động retry đến khi hết token limit và đốt hàng chục đô âm thầm. Bài viết chỉ ra pattern đốt tiền và 5 chốt chặn dev nên bật ngay.

Across 10 May 2026 benchmarks, frontier AI agents averaged below 60 percent on production tasks. Codex CLI hit 82.7 percent. ITBench fell under 50.

Skip the allowlist queue. Five production-ready defensive AI tools — open weights, hosted APIs, and self-hostable stacks — that protect real apps today, with cost and integration notes.

The GPT-5.5-Cyber capability profile beyond OpenAI's marketing: Simon Willison's evals, the Trusted Access Program scope, and what the Five Eyes briefings actually covered.

Mythos and GPT-Cyber are locked. Open-source alternatives (CodeLlama Guard, Llama Guard 3, Cisco AI defense) are not. We compared both stacks on 4 defensive tasks—the honest results.

We compared what Anthropic Mythos and OpenAI GPT-5.5-Cyber actually do on offensive testing tasks. Capabilities, refusal patterns, evals, and where each model breaks down.

Anthropic's Mythos and OpenAI's GPT-5.5-Cyber both ship locked behind allowlists. Here's what's inside each model, who actually gets access, and what the rest of us can build today.

Microsoft APM v0.9.2 (Apr 23) makes AI agent context portable — one apm.yml pins skills, prompts, MCP servers across Claude Code, Copilot, Cursor.

OpenAI Agents SDK 0.14.3 adds Sandbox Agents - Python agents that edit real files, run commands, and resume in Docker. Wire one up in 15 minutes.

Anthropic's Claude Design goes live in preview, Q1 2026's biggest web+AI launches get a full debrief, and three DX tools quietly saving engineering hours surface.

AI coding agents are no longer experimental — two deep-dives from the past 48h map the real costs, tooling landscape, and what fullstack teams are actually shipping.
