Hello.
The main topics this week include:
- OpenAI and Anthropic announcing new models (GPT-5.3 Codex / Opus 4.6) on the same day
- GitHub launching "Agent HQ" with multi-agent support
- The arrival of "Kling 3.0" video generation AI
It feels almost coordinated how OpenAI and Anthropic released their powerful coding-capable models on the exact same day. "Agency" (or being "Agentic") is the key keyword here, prominently shifting focus from mere code suggestions to executing entire tasks.
The Shift from "Co-pilot" to "Agent"
Until now, AI coding assistance has mainly played the role of a "Co-pilot," suggesting the next lines of code that a human is writing. However, looking at this week's flow with GPT-5.3 Codex, Opus 4.6, and the GitHub Agent HQ hosting them, the evolution towards "Agents" that proactively plan and execute tasks has become clear.
OpenAI releasing a dedicated macOS app also suggests an intention to include the entire local environment as an operation target, rather than just working inside a browser. It felt like a week signaling the full-scale arrival of a development style where developers become commanders, issuing instructions to AI agents and overseeing their work.

New AI Models, Services, and Updates
OpenAI: Announces Autonomous Coding Model "GPT-5.3 Codex"
OpenAI has announced "GPT-5.3 Codex," a new autonomous coding model. It made headlines by being released on the same day as Anthropic's new model (Opus 4.6).
This model excels at autonomously handling everything from planning to executing complex coding tasks. Going beyond traditional code completion, it understands the engineer's intent and can perform cross-file modifications, promising to significantly streamline the development process.
Anthropic: Releases Flagship Model "Opus 4.6"
Almost simultaneously with OpenAI's announcement, Anthropic released its flagship model, "Opus 4.6".
Competition in agent capabilities is intensifying, and Opus 4.6 also boasts high performance in complex reasoning and coding abilities. For developers, this means two powerful options have been added at once, and choosing the right one for specific characteristics is likely to become a topic of discussion.
OpenAI: Releases Codex-Dedicated macOS App
OpenAI has released a native macOS app dedicated to Codex.
This is not just a chat app, but provides a hub function that can run and manage multiple AI agents in parallel. By running on the desktop environment, access to local files and tool integration becomes smoother, potentially refreshing the development flow itself. Integration is advancing at the OS level, going beyond the framework of browser or IDE extensions.

Kling AI: Announces Video Generation Model "Kling 3.0"
Kling AI has released its latest multimodal video generation model, "Kling 3.0".
It is possible to generate videos from diverse inputs such as text, images, and audio. The improvement in video generation quality is remarkable, enabling the generation of longer and more consistent videos. The range of applications in creative fields is likely to expand even further.
Web Development Topics
GitHub: Supports Multiple Agents like Claude and Codex with "Agent HQ"
GitHub announced a new feature, "Agent HQ," allowing users to freely choose coding agents to use within GitHub and VS Code.
This allows developers to switch between models like GitHub Copilot, Anthropic's Claude, and OpenAI's Codex according to their preferences or task suitability. This move by the platform to explicitly provide "model choices" is welcomed as it eases vendor lock-in and improves the developer experience.

Anthropic vs OpenAI: Conflict in Super Bowl Ads
In the advertising slots for the Super Bowl, America's largest sports event, a "field battle" has become a hot topic, with Anthropic airing a commercial appearing to mock OpenAI, and Sam Altman responding to it.
The fact that competition between AI companies is taking place in a venue visible to the general public, beyond the tech community, symbolizes the high social influence of AI technology. Fierce battles are being waged not only in technological development but also in branding and marketing.
