UNDERSTAND IT.

AI-generated code is outpacing manual review, creating a verification bottleneck. To scale effectively, teams must shift from manual checks to an automated, source-agnostic verification layer. By utilizing automated enforcement of deterministic standards human reviewers can focus on high-level architecture and intent.

INTRODUCING CODEX PLUGIN FOR CLAUDE CODE

The Codex plugin for Claude Code gives users a simple way to pull Codex into their Claude Code workflow. It is useful for normal Codex reviews, a more adversarial review, and handing work off to Codex when a second pass from a different agent is required. The plugin delegates through the local Codex CLI and Codex app server, so it uses the system's existing local auth, configuration, environment, and MCP setup.

A MIRROR TEST FOR LLMS

The proposed "Mirror Test" assesses LLM self-awareness by challenging models to identify their own outputs without explicit cues. Testing reveals that Anthropic's Opus 4.6 model shows notable self-recognition capabilities due to its distinct token outputs, outperforming OpenAI's GPT models, which fail to recognize self-generated tokens. Despite indications of attempted self-marking, no LLM demonstrated consistent self-awareness, as none effectively communicated using message passing.

AI INFRASTRUCTURE ROADMAP: FIVE FRONTIERS FOR 2026

The first generation of AI was a world where progress meant bigger weights, more data, and stellar benchmarks. The landscape has now changed. Big labs are now designing AI that interfaces with the real world. Infrastructure optimized for scale and efficiency won't get us to the next phase. What's needed now is infrastructure for grounding AI in operational contexts, real-world experiences, and continuous learning.

AI APPLICATIONS AND VERTICAL INTEGRATION

AI application companies are increasingly becoming "full-stack" by vertically integrating either downward into the model layer or upward into the service layer. Companies like Cursor and Intercom achieve differentiation and cost efficiency by developing proprietary models, while others, such as Crosby AI and WithCoverage, focus on delivering end-to-end services. As AI capabilities evolve, these strategies allow companies to enhance performance, reduce costs, and offer comprehensive solutions.

PLENTIFUL, HIGH-PAYING JOBS IN THE AGE OF AI

AI might not eliminate high-paying human jobs due to potential constraints like limited computing power and energy usage. These constraints could lead to the principle of comparative advantage, where humans remain employed in roles despite AI's superior capabilities, because the opportunity cost of allocating AI to all tasks would be too high. As AI advances, human roles could change, but new tasks and increased wealth might sustain or even increase compensation for human jobs.

CLAUDE MYTHOS

'Mythos' is the name for a new tier of Anthropic models that are larger and more intelligent than Opus. The models get dramatically higher scores on tests of software coding, academic reasoning, and cybersecurity compared to Claude Opus 4.6. Mythos is a large, compute-intensive model that is very expensive to use and serve. Anthropic is working on making the model much more efficient before any general release.

The company appears to be running parallel experiments with multiple Avocado variants. The model appears to be able to solve complex math problems that earlier Llama models could not, but these problems have already been solved by other labs months earlier. Meta's AI leadership has reportedly discussed temporarily licensing Google's Gemini technology. Some requests within Meta AI are already being routed through Gemini models.

FUNCTION CALLING HARNESS: FROM 6.75% TO 100%

AutoBe is an open-source AI agent that takes a single natural language conversation and generates a complete backend. qwen3-coder-next has a 6.75% function calling success rate when asked to generate API data types for a shopping mall backend. AutoBe boosts that success rate up to over 99.8%. It uses a harness where type schemas constrain outputs, compilers verify results, and structure feedback pinpoints compactly where and why something went wrong so the agent can correct itself. This post dissects the engineering behind AutoBe.

AI'S CAPABILITY IMPROVEMENTS HAVEN'T COME FROM IT GETTING LESS AFFORDABLE

AI's capability improvements at the frontier have not led to increased inference costs relative to human labor. Despite rising per-task inference costs, current models achieve tasks at roughly 3% of human costs without any upward trend in median cost ratios. Models can continue advancing even under strict cost constraints, enabling profitable automation with AI cost ratios remaining well below human levels.
