Model summary

AIGENCY V4 is the multimodal successor to AIGENCY V3, developed by eCloud Yazılım Teknolojileri and released to production in Q2 2026. The model retains V3's four sovereignty principles — zero external parameter dependency, sovereign data residency, transparent architectural documentation, and Turkish morphological context fidelity — and adds a sovereign 8B-parameter vision encoder for image, document, chart, and visual-math understanding.

Evaluation

A comprehensive single-session evaluation was conducted on 27 April 2026 against the production API. 13,344 real API calls across 22 distinct benchmarks were executed; every result is reported with a Wilson 95% confidence interval, deterministic subsampling (seed=42), and an open dataset identifier.

V4 is at frontier level on grade-school math and scientific reasoning, upper-mid frontier on code generation, lower-mid frontier on general academic and instruction following, and in active development on graduate-level expert knowledge and multimodal. The V4.1 roadmap (Q4 2026) targets MMLU-Pro 0.65, GPQA Diamond 0.55, and average latency 4 s.

Operational performance (single-session, 27 April 2026)

Total API calls: 13,344
Persistent error rate: 0.3%
Average latency: 9.55 s · p50 4.39 s · p95 32.77 s · p99 33.59 s

Intended use

Primary deployment domains:

Public-sector and government workloads requiring KVKK residency
Legal and legal-tech (statute search, contract analysis — Tural model integration)
Education and higher education (Turkish academic, exam prep, course assistants)
Banking, finance and insurance (Turkish-heavy KYC/AML)
Healthcare administrative workloads (KVKK-compliant document handling)
Media, publishing and editorial (Turkish grammar precision)
Defence and critical infrastructure (sovereign architecture)
Software, R&D and engineering (code generation, large-codebase analysis)

Out-of-scope or non-recommended:

Clinical diagnosis or medical advice (administrative use only)
Autonomous critical decisions without human review
Graduate-level scientific research where GPQA-Diamond–class accuracy is required (use frontier model + V4 hybrid)
High-fidelity multimodal reasoning where MMMU > 75 is required (await V4.1)

Safety and compliance

KVKK §5 / §12 (Turkish PDPA) compliant — KVKK-resident hosting (TR DC)
ISO/IEC 27001 — IT-ISMS, risk and control matrix
NIST SP 800-207 (Zero-Trust) — mTLS, least privilege, continuous monitoring
EU AI Act (ratified 2025) — high-risk classification with model card
Memory encryption: AES-256-XTS (RAM), ChaCha20-Poly1305 (LTM disk)
Image cache: AES-256-GCM, 30 MB limit, 24h TTL
Pre-encoding visual safety filter + post-encoding output check

Known limitations

GPQA Diamond / MMLU-Pro gap — 35-50pp behind frontier; graduate-level expert knowledge is a V4.1 target.
First-generation multimodal — vision encoder is 8B; V4.1 plans to scale to 16B.
Latency 2-3× frontier — vision-encoder overhead, multimodal safety filter; V4.1 targets ≤ 4 s avg.
Multimodal subsample size — DocVQA n=24, MMMU n=30 (HF cache constraints); CIs are wide.
Multilingual non-TR evaluation not published — global-scale claim is currently Turkish-anchored.

Hukuk ve hukuk teknolojileri (mevzuat arama, sözleşme analizi)
Eğitim ve yükseköğretim (Türkçe akademik, sınav hazırlık)
Bankacılık, finans ve sigorta (Türkçe-yoğun KYC/AML)
Sağlık idari iş yükleri (KVKK uyumlu belge işleme)

Bilinen kısıtlar

GPQA Diamond / MMLU-Pro frontier'ın 35-50pp gerisinde — V4.1 hedefi.
Multimodal ilk üretim sürümü — V4.1'de 16B vision encoder planlandı.
Latency frontier'ın 2-3 katı — V4.1 hedefi ≤ 4 s ortalama.
Multimodal subsample boyutu küçük (DocVQA n=24, MMMU n=30); CI geniş.
TR-dışı çok-dilli profil yayımlanmadı — küresel iddia şu an TR-merkezli.
