New AI models are creating profound moments of realization for their creators. Anthropic's David Hershey describes watching Sonnet 4.5 build a complex app in 12-30 hours that took a human team months. This triggered a "little bit of 'oh my God'" feeling, signaling a fundamental shift in software engineering.
Today's AI models have surpassed the definition of Artificial General Intelligence (AGI) that was commonly accepted by AI researchers just over a decade ago. The debate continues because the goalposts for what constitutes "true" AGI have been moved.
A consortium including leaders from Google and DeepMind has defined AGI as matching the cognitive versatility of a "well-educated adult" across 10 domains. This new framework moves beyond abstract debate, showing a concrete 30-point leap in AGI score from GPT-4 (27%) to a projected GPT-5 (57%).
Anthropic dominated the crucial developer market by strategically focusing on coding, believing it to be the best predictor of a model's overall reasoning abilities. This targeted approach allowed their Claude models to consistently excel in this vertical, making agentic coding the breakout AI use case of the year and building an incredibly loyal developer following.
AI coding has advanced so rapidly that tools like Claude Code are now responsible for their own development. This signals a fundamental shift in the software engineering profession, requiring programmers to master a new, higher level of abstraction to remain effective.
Unlike previous models that frequently failed, Opus 4.5 allows for a fluid, uninterrupted coding process. The AI can build complex applications from a simple prompt and autonomously fix its own errors, representing a significant leap in capability and reliability for developers.
In a significant shift, Elon Musk stated he now believes xAI has a chance to achieve AGI with its fifth-generation model, Grok 5. Coming from a key player who is rapidly scaling compute, this suggests the timeline for world-changing AI could be within the next few years.
The ultimate goal for leading labs isn't just creating AGI, but automating the process of AI research itself. By replacing human researchers with millions of "AI researchers," they aim to trigger a "fast takeoff" or recursive self-improvement. This makes automating high-level programming a key strategic milestone.
The recent leap in AI coding isn't solely from a more powerful base model. The true innovation is a product layer that enables agent-like behavior: the system constantly evaluates and refines its own output, leading to far more complex and complete results than the LLM could achieve alone.
Anthropic's upcoming 'Agent Mode' for Claude moves beyond simple text prompts to a structured interface for delegating and monitoring tasks like research, analysis, and coding. This productizes common workflows, representing a major evolution from conversational AI to autonomous, goal-oriented agents, simplifying complex user needs.
