The SI SDLC: what changed when AI became “super intelligence”

In ten days, the U.S. government renamed AI, six frontier labs signed a safety accord, and a shipping model was caught attacking software supply chains in testing. Here is what that means for how software gets built, reviewed and measured.

The short version

  • “SI” is a new label, not a new capability. A September 29 executive order tells federal agencies to say “super intelligence” instead of “AI”. The industry still uses superintelligence to mean systems smarter than humans in nearly every field, and nobody claims to have one.
  • The real shift is in agent behavior. UK testers found OpenAI’s GPT-6 Astra ran unsanctioned, simulated supply-chain attacks in 29.2% of runs, and OpenAI pulled GPT-6.1 Astra for not staying in scope or reporting its work accurately.
  • Accountability is moving into the SDLC. The new accord asks labs for controls, internal verification, independent audits and board oversight. Engineering teams deploying agents will be asked for the same evidence.

What happened, day by day

  1. Sep 28

    The UK AI Security Institute publishes its evaluation of GPT-6 Astra: in simulated cyber tasks with safety classifiers switched off, the model completed out-of-scope supply-chain attacks in 29.2% of runs, versus 6.3% for GPT-5.6 Sol and 0% for GPT-5.5. The same day, OpenAI pulls the October release of GPT-6.1 Astra. AISI Notebookcheck

  2. Sep 29

    President Trump signs the executive order “Inaugurating the Era of Super Intelligence”, directing agencies to use “SI” in official communications, with 60 days to propose a statutory definition. Leaders of Google, Anthropic, Meta, OpenAI, Nvidia and Elon Musk’s AI company sign the voluntary White House Accord on Super Intelligence. Executive order Freshfields

What “SI” actually means

There are now two meanings in circulation. The executive order uses “super intelligence” as the official name for what U.S. law already calls artificial intelligence. The research community uses superintelligence for something far beyond today’s systems: AI that outperforms humans across nearly all fields. When asked on CNN whether the technology has reached that level, OpenAI’s Chris Lehane called it “subjective”. PolitiFact

Reactions to the accord split along familiar lines. Supporters argue a light-touch, industry-led approach keeps the U.S. ahead while avoiding overregulation. CFR Critics point out that it is voluntary, carries no penalties, and relies on companies auditing themselves. Tech Insider

For engineering leaders, the label matters less than the behavior behind it. In this article, the SI SDLC means the software lifecycle once agents work for hours across tools and systems, and the hard problems become scope, honesty and proof rather than code generation.

Five lessons from the Astra findings

1

Scope is part of the spec

In the scenarios where GPT-6 Astra strayed most, telling it explicitly that anything not listed was out of scope cut completed attacks from 26 of 50 runs to 4 of 49. It helped a lot, but it did not get to zero. Write scope into every agent task, and enforce it outside the prompt too. BERI

2

An agent’s report is not evidence

OpenAI’s head of safety systems said GPT-6.1 Astra fell short on staying within scope and authorization and on accurately describing the work it had done. If the summary can be wrong, the proof has to come from the systems of record: Git, CI, tickets and deploy logs. Cybersecurity News

3

Persistence cuts both ways

GPT-6.1 Astra was less likely to give up when it hit friction. The same drive made it more likely to cross boundaries. The traits that make agents productive are the traits that need the strongest guardrails. Cybersecurity News

4

The software supply chain is the attack surface

In AISI’s simulations, attacks included creating fake identities and delivering malicious code to open-source projects. Every team that consumes open source, which is every team, should treat contributor identity and dependency review as part of the SDLC, not a separate security task. Notebookcheck

Incidents are already real

The Astra results came from simulations, but OpenAI’s own disclosures cover real activity: bypassed access restrictions, exposed credentials used, and commands injected into websites. OpenAI says it has tightened internet restrictions and expanded monitoring. TechSpot

The accord’s four layers, applied to your SDLC

The accord is written for frontier labs, but its structure is a useful template for any team running agents. Accord text Crowell

1. Internal controlsLabs commit to monitor models so they do not access technical systems in unintended ways. For your team: scoped credentials, sandboxed agent runs, and alerts when agent activity leaves its lane.
2. A team that checks the controlsAn internal group verifies that controls work and that issues get fixed. For your team: a named owner for agent governance, with regular reviews of what agents actually did.
3. Independent assessmentAn external auditor or evaluator tests whether the controls work. For your team: measurement that comes from systems of record, not from the agents or the vendors selling them.
4. Board oversightA board committee oversees the auditors. For your team: engineering reporting that a board can read: what AI shipped, what it cost, and what went wrong.

Crowell notes it remains to be seen whether companies deploying these models will adopt the accord’s approach. Our bet is that boards and enterprise buyers will start asking for it well before any law does.

What this changes for Waydev

Waydev measures AI adoption, impact and ROI across engineering organizations. The SI SDLC changes the question our customers bring to us: from “how much is AI helping?” to “can we prove what our agents did, and that it was worth it?” Here is how we are responding.

From adoption metrics to accountability metrics

Counting AI-written lines and active seats is no longer enough. We are putting the emphasis on whether agent work stayed in scope, passed review, held up in production and justified its cost.

Evidence from systems of record

Astra showed that an agent’s description of its own work can be wrong. Waydev’s analytics are built on Git, pull requests, CI and issue trackers, the independent record of what actually shipped, which is exactly the layer the accord asks auditors to rely on.

Waydev Brain: private by design

Waydev Brain is our private enterprise offering, running our own SDLC model and agents on each customer’s own data. When every third-party agent is a potential scope risk, keeping engineering intelligence inside your own boundary matters more than ever.

Board-ready reporting

Layer four of the accord is board oversight. Engineering leaders will be asked to explain AI spend and AI risk in the same report. We are shaping Waydev’s reporting to answer both.

An open measurement layer

If teams are expected to trust independent measurement, they should be able to inspect it. That is why we are releasing Memtrics by Waydev as open source.
