Gentoo Logic · Modeling Warehouse↗ Modeling reference

Architecture intelligence · organized by the model

Which foundational model powers what — and how close they run to it.

Each model is a center of gravity. Companies orbit every model they use; distance = how directly they consume it (inner = Native, outer = Middleware). Dot size = whether that's their primary, secondary or tertiary model. Tap a company to peek; expand for the full stack; turn on Compare mode to diff up to three.

▶ Tap a model pill to raise its orbit to the top · tap a dot for a quick peek (then ⤢ for full detail) · Compare mode → tap up to 3 dots → diff their stacks.

Foundational models: Pharia 1 / Pharia-1-LLM-7B — Native (own / self-hosted weights) (primary); Luminous (legacy family) — Native (own / self-hosted weights)

Stack: object

Compliance: sovereign, EU-compliant, access control, monitoring

Aleph Alpha’s current product layer appears to be PhariaAI, a sovereign enterprise stack that includes knowledge capture, development, operation, access control, and monitoring components. Public materials also show first-party API access and containerized deployment patterns, but the exact production datastore and hosting mix are not fully disclosed, so the infrastructure is best characterized as hybrid rather than purely on-prem or purely cloud.[2][5][10]

Anduril

Defense · Hybrid · Off the LLM map (in-house non-LLM ML)

Foundational models: in-house non-LLM ML only

Stack: Proprietary internal telemetry stores (Lattice platform), Data lake/warehouse for long-term sensor/log storage (likely cloud + on-prem, exact vendors undisclosed), Streaming/message bus layer (Kafka/Pulsar-like per system design guidance, not confirmed as production)

Compliance: ITAR (International Traffic in Arms Regulations) – required for US defense exports and autonomous weapons systems, DoD cybersecurity controls (e.g., NIST SP 800-53 / FedRAMP-aligned baselines for handling defense telemetry), SOC 2–style controls for hyperscale manufacturing and software-defined facilities (inferred from defense SaaS norms), Defense-specific secure manufacturing and export controls for Arsenal-1 and international facilities

Anduril’s production architecture is built around its proprietary **Lattice** autonomy platform as the software backbone for autonomous systems and the **Arsenal** software-defined manufacturing stack, integrating sensor fusion, decision logic, and production control across a mix of cloud and tightly controlled on‑prem deployments.[10][12][13] Public material focuses on capabilities and manufacturing rather than concrete cloud/database vendor disclosures, so specific underlying services (e.g., exact clouds and DB engines) remain intentionally opaque.[3][10][12]

Anthropic

AI/LLM · Multi-Cloud · Native (own / self-hosted weights)

Foundational models: Claude 3.5 family (Opus / Sonnet / Haiku variants) — Native (own / self-hosted weights) (primary); Claude 3.x / Claude Instant (legacy/previous generations) — Native (own / self-hosted weights)

Stack: PostgreSQL[13], vector databases (e.g., Qdrant)[4][13], Redis/Valkey (cache)[5][9][13], object storage (cloud blob storage, e.g., S3/GCS)[1][13]

Compliance: SOC 2 (inferred, typical for enterprise AI SaaS; not explicitly confirmed)[2][3], ISO 27001 (inferred, typical for scale enterprise workloads; not explicitly confirmed)[2][3], privacy-preserving sandbox perimeter for agents (policy/architecture control rather than formal cert)[2][11], network, application, and API security enforcement via distributed infrastructure (Akamai)[12]

Anthropic runs **Claude** and related services on a safety-first **multi-cloud** compute fabric spanning AWS Trainium2, Google TPUv7 and NVIDIA GPUs, fronted by Kubernetes‑based microservices (API gateways, orchestration, rate limiting, caching, and safety filters), with state held in PostgreSQL, vector stores, Redis, and cloud object storage.[1][10][13] Production offerings like Claude API and Managed Agents expose a fully managed orchestration and agent runtime, while emerging self‑hosted sandboxes move tool execution into customer infrastructure but keep Claude inference, routing, and session state on Anthropic’s cloud.[2][3][11]

Asana
