AI Self-Improvement Era Begins as Labs Use AI to Build AI
The latest issue of 'The Sequence Knowledge' newsletter delves into the emerging era of recursive self-improvement in AI. It highlights that in the past year, major AI labs have openly acknowledged that their AI systems are now integral to their own development processes. Notably, Anthropic reported that Claude authored over 80% of the code merged into its production codebase as of May 2026. OpenAI disclosed that GPT-5.3-Codex assisted in debugging its own training process and managing parts of its deployment, while DeepMind's AlphaEvolve has been generating algorithmic improvements that are incorporated into the infrastructure used to train other models. The article frames this as the end of abstract debates about AI self-improvement, shifting the focus to practical questions about which tasks AI performs, its effectiveness, and the oversight mechanisms in place.
Major AI labs (Anthropic, OpenAI, DeepMind) are openly integrating AI into their own development pipelines, signaling a shift in how AI systems are built and maintained, which has significant implications for the AdTech/MarTech industry's use of AI technologies.

AI self-improvement fears spark existential concerns at Anthropic and OpenAI
Researchers at Anthropic and OpenAI have raised fresh concerns about recursive self-improvement (RSI), where AI systems help develop more capable successors, potentially leading to rapid capability growth and loss of human control. Both companies report that autonomous model improvement is happening faster than expected. The concerns were triggered by Anthropic's alignment lead Evan Hubinger stating a >10% chance AI could kill all humans within a decade, and a colleague's resignation. OpenAI's chief scientist Jakub Pachocki warned about unpreparedness for rapid capability jumps. Researchers across both labs have echoed these warnings, emphasizing the lack of a scientific plan to address RSI risks. Anthropic outlined three possible future scenarios, including one where humans lose substantial control over AI development.
Musk Says AI Self‑Improvement Has Begun
At the Abundance Summit Elon Musk argued that AI has entered recursive self‑improvement, with newer models helping build successors and human involvement shrinking; he predicted fully automated AI improvement could appear within a year or two and linked this trend to humanoid robots like Optimus, forecasting a large boost to economic output. The newsletter also reports Sam Altman saying AI has become unpopular in the U.S., a German startup demonstrating sensor‑and‑edge‑AI backpacks for cockroach reconnaissance, and a journalist suing Grammarly over an “Expert Review” feature that attributed suggested edits to real journalists without permission. The issue’s TL;DR lists product updates and integrations from Anthropic, OpenAI, Google, Meta/Facebook Marketplace, Bumble, and Microsoft.
The Race to Recursive Self-Improving AI
An analysis piece published on 2026-05-26 argues that the AI conversation is shifting from AGI hype toward recursive self-improvement (RSI), which the author views as a likely industry theme by 2027. The article surveys startups and research activity — naming firms such as Anthropic, Recursive Superintelligence, DeepSeek and chip-focused players — and cites financing, alumni networks from DeepMind/OpenAI, and partnerships (e.g., Google/Blackstone) as factors accelerating enterprise AI and prospective RSI efforts. The author discusses potential economic and scientific implications, questions the commercial viability of buzzy RSI startups, and predicts 2027 as the start of a broader “Machine Economy” era driven by self-improving AI and enterprise adoption.
