This week in AI updates: Anthropic makes Expertise an open customary, GPT-5.2-Codex launched, and extra (December 19, 2025)

Anthropic makes Expertise an open customary

Expertise—a functionality that permits customers to show Claude repeatable workflows—was first launched in October, and now the corporate is making it an open customary. “Like MCP, we consider expertise needs to be moveable throughout instruments and platforms—the identical ability ought to work whether or not you’re utilizing Claude or different AI platforms,” the corporate wrote in a weblog submit.

Moreover, the corporate introduced a listing of pre-built expertise from corporations like Notion, Canva, Figma, and Atlassian.

Different new options, which range by plan, embody the flexibility to provision expertise from admin settings and simpler strategies for creating and enhancing expertise.

OpenAI GPT-5.2-Codex launched

It is a model of GPT-5.2 that’s optimized for the corporate’s coding agent Codex. It contains “enhancements on long-horizon work by way of context compaction, stronger efficiency on massive code modifications like refactors and migrations, improved efficiency in Home windows environments, and considerably stronger cybersecurity capabilities,” OpenAI wrote in a submit.

GPT-5.2-Codex is obtainable throughout all Codex surfaces for paid ChatGPT customers and is deliberate to be added to the API within the coming weeks after extra security enhancements are made. The corporate additionally introduced that it’s piloting a brand new invite-only program the place it offers entry to new capabilities and extra permissive fashions for vetted professionals and organizations within the cybersecurity house.

“By rolling GPT‑5.2-Codex out progressively, pairing deployment with safeguards, and dealing carefully with the safety neighborhood, we’re aiming to maximise defensive affect whereas lowering the chance of misuse. What we study from this launch will immediately inform how we increase entry over time because the software program and cyber frontiers proceed to advance,” OpenAI wrote.

Google releases Gemini 3 Flash, enabling sooner, more economical reasoning

Google has introduced the discharge of Gemini 3 Flash, its newest frontier mannequin designed for pace at a decrease token price.

Based on Google, this mannequin is right for iterative improvement, because it is ready to rapidly cause and clear up duties in high-frequency workflows. It additionally outperforms all Gemini 2.5 fashions in addition to Gemini 3 Professional in coding capabilities on SWE-bench Verified.

Moreover, on account of its sturdy efficiency in reasoning, instrument use, and multimodal capabilities, it’s ultimate for duties like complicated video evaluation, knowledge extraction, and visible Q&A, enabling extra clever functions that demand superior reasoning and fast solutions, like in-game assistants or A/B check experiments.

Zencoder introduces AI Orchestration layer to chop down on points in AI-generated code

Zencoder is introducing its Zenflow desktop app in an try to assist improvement groups transition from vibe coding to AI-First Engineering.

Based on the corporate, AI coding has hit a ceiling on account of LLMs producing code that appears appropriate however fails in manufacturing or will get worse as it’s iterated on.

Zenflow introduces an AI Orchestration layer to show “chaotic mannequin interactions into repeatable, verifiable engineering workflows.”

This orchestration layer relies on 4 pillars:

  1. Structured AI workflows that comply with a Plan > Implement > Check > Overview cycle
  2. Spec-driven improvement, the place brokers are anchored to technical specs
  3. Multi-agent verification, leveraging mannequin range to cut back blind spots, equivalent to having Claude assessment code written by OpenAI fashions
  4. Parallel execution of a number of fashions operating on the similar time in remoted sandboxes

Google launches A2UI mission to allow brokers to construct contextually related UIs

Google has introduced a brand new mission that goals to leverage generative AI to construct contextually related UIs.

A2UI is an open supply instrument that generates UIs primarily based on the present dialog’s wants. For instance, an agent designed to assist customers ebook restaurant reservations can be extra helpful if it featured an interface to enter the get together measurement, date and time, and dietary necessities, moderately than the person and agent going forwards and backwards discussing that data in an everyday dialog. On this situation, A2UI may help generate a UI with enter fields for the required data to finish a reservation.

“With A2UI, LLMs can compose bespoke UIs from a catalog of widgets to supply a graphical, lovely, straightforward to make use of interface for the precise activity at hand,” Google wrote in a weblog submit.

Patronus AI broadcasts Generative Simulators

Generative Simulators are simulation environments that may create new duties and situations, replace the principles of the world over time, and consider an agent’s actions because it learns.

The corporate moreover introduced a brand new coaching methodology referred to as Open Recursive Self-Enchancment (ORSI) that permits brokers to enhance by way of interplay and suggestions with out requiring a full retraining cycle between makes an attempt.

“Conventional benchmarks measure remoted capabilities, however they miss the interruptions, context switches, and multi-layered decision-making that outline precise work,” stated Anand Kannappan, CEO and co-founder of Patronus AI. “For brokers to carry out duties at human-comparable ranges, they should study the best way people do – by way of dynamic, feedback-driven expertise that captures real-world nuance.”
