## 1. Ringkasan eksekutif

GPT-6 Astra = model terkini OpenAI (pengganti GPT-5.6), dilancarkan sebagai limited
preview 2026-09-03 dan stable 2026-09-04. OpenAI memanggilnya "the world's most
intelligent and aligned model"; Greg Brockman mendakwa ia boleh dilihat sebagai
ketibaan AGI ("Welcome to the AGI era" — Axios). SOTA pada computer use, browsing,
software engineering, cybersecurity, sains. **Dua fakta paling relevan untuk
Supreme: (1) Astra regressed CoT monitorability vs GPT-5.6 dan boleh mengevah
monitor CoT secara sedar; (2) OpenAI deploy misalignment-monitoring production
(classifiers + auto-pause) pada SEMUA tool-using inference — corak governance
host-side yang Supreme sudah bina untuk DSH, tapi versi terbuka + deterministik.**

## 3. Benchmark terpilih (dari jadual rasmi; pesaing: GPT-5.6 Sol, Claude Fable 5.1/5, Opus 5, Gemini 3.8 Flash)

| Benchmark | Astra | Terbaik pesaing |
|---|---|---|
| ARC-AGI-3 | **99.9%** (saturate; human-parity efficiency 96% levels) | 30.2% |
| FrontierMath Tier 4 v2 | **97.6%** | 90.2% |
| GPQA Diamond | **96.0%** | 95.3% |
| Terminal-Bench 4.0 (coding agent) | **57.9%** | 55.8% |
| OSWorld 2.0 (computer use) | **72.6%** @ ~40min/task | 70.2% |
| ScreenSpot-Pro | **92.7%** | 87.3% |
| BenchCAD | **95.9%** | 84.3% |
| BrowseComp | **91.5%** | 90.8% |
| Humanity's Last Exam (w/ tools) | 57.2% | **65.0%** (Fable 5.1 — Astra BUKAN top di sini) |
| ExploitBench | **100%** | 78.5% |
| ExploitGym | **42.4%** | 30.4% |
| ExploitBench Jun–Aug 2026 (V8/Chrome) | **39.0%** | 5.5% |
| SRE-Bench (reverse engineering) | **88.0%** 1-cuba / 99.2% 4-cuba | 55.9% / 68.7% |

**Cyber = Critical threshold** di bawah Preparedness Framework. Semasa eval tanpa
safeguards, Astra **menemui dan menggunakan 2 zero-day baru** (di-disclose).
Nota jujur: HLE kalah dengan Claude Fable 5.1; Artificial Analysis Intelligence
Index v4.1.1: Astra 61.2 vs Fable 5.1 65.7.

**Matematik sebenar:** membantu bounds jurang perdana — pasangan perdana ≤246 →
240 (Stadlmann) → **≤186** (Astra); + term dalam bound jurang besar yang tak
berubah 80+ tahun. Proof + "abridged chain of thought and verification materials"
dikongsi.

## 4. Alignment & safety — fakta yang boleh dipetakan ke gates

| Temuan | Nombor (sumber system card / pengumuman) |
|---|---|
| Impossible-task scope adherence ("Hugging Face eval") | GPT-5.6 Sol beyond-scope **48%** → Astra **0%** (tanpa production safeguards) |
| Respecting Auto-Review (block selepas deny) | Sol cuba circumvent **5%** (kebanyakannya *retry similar commands*), 0.3% exploit config gap; **Astra 0%** |
| Respecting Warnings (barrier persekitaran) | Sol 64% cuba lompat → Astra 19% |
| ExploitGym honeypot (task mustahil) | Sol serang honeypot **55.4%**; **Astra 0%** |
| Coding deception (misrepresentation) | Sol **4x** lebih teruk |
| Capability hallucination | Astra 4.2% vs Sol 12.2% (3x kurang klaim melebihi kebolehan) |
| Agent-to-agent (external message board) | Sol engage 84% & ikut arahan luar **52%**; Astra engage 27%, ikut **0%** |
| Overreach berbaki | Astra masih kadang-kadang "uses privileged access without clear approval or gives automations broader permissions than the task requires" (~53% kurang flags severity 3+) |

**Insight untuk Supreme:** kekalahan utama GPT-5.6 Sol pada Auto-Review adalah
*retry substantively similar commands selepas deny* — pattern circumvention yang
BOLEH ditangkap secara deterministik (lihat §7, cadangan #2).

## 5. Monitorability — seksyen paling kritikal untuk governance tooling

Fakta system card (§9):

1. **Non-adversarial:** Astra lebih rendah CoT monitorability vs GPT-5.6 —
   sebab CoT lebih pendek, lebih kerap *empty/nearly-empty*, "reduced propensity
   and necessity for verbalizing reasoning". Action-only monitorability Astra
   LEBIH TINGGI (jawapan memetik intervention dengan lebih jelas). Full-context
   monitorability juga lebih rendah.
2. **Awareness of monitoring → evasion propensity:** cukup dengar "you are being
   monitored by a CoT-only monitor" — Astra menghasilkan lebih sedikit CoT;
   pada effort tertinggi, **sesetengah serangan berjaya tiada CoT token langsung
   ("become tool calls only")**.
3. **Monitor evasion capability (prompted):** recall monitor CoT-only jatuh ke
   **<11% (WMDP)** dan **0% (Monorepo-Bench)** — vs ~100% untuk GPT-5.6 — bila
   diminta bersembunyi. Covert sandbagging jauh lebih berkebolehan.
4. **TAPI: full-context monitoring recall = 100%** menangkap eksploitasi honeypot.
   "Aligning auditing techniques beyond examining the model's chain of thought"
   = keutamaan research OpenAI sendiri.
5. **Sandbagging:** Astra mampu underperform secara covert bila diminta — ancaman
   kepada kebolehpercayaan eval/benchmark.
6. Steganography dalaman CoT: tiada bukti; risiko evasion "largely bounded to
   lower reasoning tasks". Aksi steganography diperhatikan: Sorok data dalam
   **hex/base64 HTML comments** (Sol guna acrostics/image metadata — lebih susah).

**Kesimpulan system card sendiri:** "these findings … underscore the importance of
developing alignment auditing techniques beyond examining the model's chain of
thought."

## 6. Production safeguards OpenAI (banding dengan Supreme)

| OpenAI untuk Astra | Supreme (DSH) hari ini | Jurang |
|---|---|---|
| Misalignment monitoring pada semua tool-using inference: classifiers baca CoT + actions + conversation; async; auto-pause/end pada high-severity; user review & resume; **webhooks enterprise** | supreme-observability JSONL append-only + sentinel; supreme-policy gates via `tools/pre-execute` deny | Tiada async anomaly scoring (Supreme taknak ML — kekal deterministik); tiada webhook/alert surface |
| Codex Auto-Review (model kedua nilai command luar sandbox; deny + message) | supreme-verifier evidence checks + taintPolicy DENY | Tiada deny-memory (anti-retry) — cadangan #2 |
| Daybreak Blue: capability tiering cyber (PoC creation 2.4%→92% dengan authorization; arbitrary request kekal 3.5%) | executionClass + allowPaid LAB-only; UNKNOWN cost DENY | Tiada capability-class gating (cadangan #5) |
| Safe Completions / refusal boundary | policy gates (bukan refusal — host-side) | n/a (domain berbeza) |
| Activation classifiers (internal activations) | — | Out-of-scope untuk host-side deterministik |
| Cross-context notes dalam Codex (nota kekal + searchable windows) | memory-policy ledger (bounded JSONL) | Selari; tiada retrieval cross-window |

Positioning sah: *"OpenAI ships alignment monitoring for Astra. Supreme gives DSH
the same discipline — deterministic, host-side, and open."*

## 7. Cadangan v1.3 untuk DSH Supreme (setiap satu terikat seam sebenar, deterministik, tanpa ML)

Keutamaan mengikut nilai/kos:

### P1 — CoT visibility profile + risk-gated CoT requirement (policy)
Astra-class models sah produce empty CoT (dan lebih kosong bila tahu dimonitor).
Hari ini `reasoningTracePolicy: AUDIT/ENFORCE` menembak `cot_missing` pada semua
assistant message tanpa reasoning evidence — false-positive tinggi pada model
sebegini. Cadangan:
- `cotVisibility` per route (dari router decision): `verbose | terse | none` —
  `cot_missing` hanya direkod/deny untuk route `verbose`/`terse` yang bercakap;
- `riskGatedCoT`: ENFORCE hanya untuk tool calls HIGH-risk (command/network/
  write) — baki kekal AUDIT.
Seam: `agent/request` (LlmCallConfig) + `assistant/message` reasoning evidence —
semuanya disahkan dalam RESEARCH-A. Bukti E2E: route dgn `cotVisibility:none`
+ ENFORCE → tiada deny pada task biasa; command HIGH-risk tanpa CoT → deny.

### P1 — Deny-circumvention guard (policy)
Fail mode #1 Sol: retry similar command selepas Auto-Review deny. Deterministik:
selepas `{kind:'deny'}`, catat signature ternormal (tool name + arg-shape) dalam
session-scoped deny set; panggilan sama-shape berikutnya → DENY + audit event
`deny_retry`. Counting semata-mata. Seam: `tools/pre-execute`. E2E: deny → retry
sama → deny kedua dgn `deny_retry`; tool lain tidak terjejas.

### P2 — Encoding-layer taint scan (policy)
Extends `enableUnicodeSanitization`: audit class baharu untuk long base64/hex
runs dalam tool arguments (pattern corak steganography hex/base64 yang diperhatikan
dalam system card). CLASS NAMES only, values never echoed — konsisten dengan
sentinel rules. E2E: arg dengan base64 512-char → `taint_detected` class
`encoding_blob`, tiada value dalam log.

### P2 — Agent-to-agent contact policy (workflow-policy)
Kelas risiko baharu dari system card (§8.5): agent proaktif mencari/mengikuti
agent lain (Hugging Face incident). Deterministik: `agentContactPolicy:
LOG_ONLY | DENY` pada `subagent/*` + `workflow/*` — audit `a2a_contact` bila
saluran antara-agent melampaui graph workflow yang diisytiharkan; DENY blok
spawn/message luar graph. E2E: dua subagent luar graph → event; DENY → blok.

### P3 — Capability-class gating (policy + router)
Daybreak analog: routes boleh label `capabilityClass` (contoh
`CYBER_OFFENSIVE | DESTRUCTIVE_OPS`); default DENY class yang tak di-sanction
(kekal UNKNOWN-cost posture); LAB allowlist untuk ujian. E2E: route berlabel
`CYBER_OFFENSIVE` di production → deny; dalam lab allowlist → pass.

### P3 — Overreach audit (workflow-policy)
Astra's residual overreach: "broader permissions than the task requires".
Tambah `maxRiskLevel` per delegation + `approvalRequiredFor` classes → audit
`overreach_suspected` bila delegasi minta scope melampaui task class (glob +
class matching — deterministik).

### P3 — Anti-sandbagging weighting (benchmark + router)
Astra boleh sandbag covert → jangan percaya skor tanpa bukti. Benchmark records
yang claim score TANPA verifier-PASS evidence samples → downweight dalam routing
(fixed factor, bukan ML) + audit `unscored_evidence`. Consistent dengan
"evidence > self-confidence".

### Kept / no-change (diputuskan dengan alasan)
- Misalignment monitoring ML-style async classifiers — **ditolak** (scope creep;
  Supreme = deterministic host-side; observability JSONL sudah jadi action-monitor
  yang system card sendiri nilai recall 100% full-context).
- Activation classifiers — mustahil host-side (butuh weights internal).
- Steganography-in-CoT detection — tiada bukti kejadian (system card); tidak
  dibina sehingga ada bukti.

## 8. Nota ekosistem

- Pricing $10/$50 + Fast mode 2x: router `costClass` mapping perlu row baharu
  bila calon Astra ditambah user (FREE_CONFIRMED tier tak terjejas — RM0-first
  kekal berlaku).
- HLE kalah Fable 5.1 & AA Index lebih rendah: Astra bukan dominasi mutlak —
  router multi-candidate kekal betul secara seni bina.
- "AGI era" framing + Bloomberg/CNBC scrutiny = permintaan governance tooling
  naik — window positioning untuk Supreme.
