Last updated: 2026-03-14

Hardware Support Matrix

GPU Support

Vendor Generation Models Backend Support Level Notes
NVIDIA Ada Lovelace RTX 4090, 4080, 4070 Ti/Super CUDA 12.x Full Primary development target
NVIDIA Blackwell RTX 5090, 5080 CUDA 12.x Full Tested on RTX 5080
NVIDIA Ampere RTX 3090, 3080, 3070 Ti CUDA 12.x Full
AMD RDNA 3 RX 7900 XTX/XT, 7800 XT, 7700 XT ROCm 6.x (HIP) Full
AMD CDNA 3 MI300X ROCm 6.x (HIP) Full Data center GPU
Intel Alchemist Arc A770, A750, A580 XPU (oneAPI) Supported Via Vulkan for LLM
Intel Battlemage Arc B-series XPU (oneAPI) Supported Via Vulkan for LLM
Apple M4 M4, M4 Pro, M4 Max, M4 Ultra Metal / MPS Full Via llama.cpp Metal
Apple M3 M3, M3 Pro, M3 Max, M3 Ultra Metal / MPS Full
Apple M2 M2, M2 Pro, M2 Max, M2 Ultra Metal / MPS Full
Apple M1 M1, M1 Pro, M1 Max, M1 Ultra Metal / MPS Full
CPU x86_64 AVX2 or AVX-512 required CPU Supported Slow but functional
CPU ARM64 NEON required CPU Supported Slow but functional

Support levels:

  • Full: Actively tested, optimized, documented. Issues prioritized.
  • Supported: Tested, functional. Issues accepted but lower priority.
  • Community: Not actively tested. Community contributions welcome.

Driver Versions

GPU Vendor Minimum Driver Recommended Driver Notes
NVIDIA 535.x 550.x or later CUDA 12.2+ required
AMD ROCm 5.7 ROCm 6.0+ HIP runtime
Intel Level Zero 1.3 Latest stable oneAPI 2024.0+
Apple macOS 14.0 macOS 15.0+ Metal 3 for best performance

System Requirements

Resource Minimum Recommended Notes
CPU 4 cores, x86_64 or ARM64 8+ cores AVX2 required for x86_64
RAM 16 GB 32 GB+ Swap is disabled by design
Storage 64 GB SSD 256 GB+ NVMe For OS + models + vault
GPU VRAM 8 GB 16 GB+ Determines max model size
Network Optional Ethernet Only needed for initial setup / airlock
TPM Optional TPM 2.0 Required for measured boot and key sealing
UEFI Required Secure Boot capable Secure Boot optional but recommended

Software Compatibility

Base OS

Component Version Support Window Notes
Fedora Silverblue 42 Until Fedora 42 EOL (~13 months from release) Current base
uBlue framework Latest Follows Fedora lifecycle Image build framework
rpm-ostree 2024.x+ Follows Fedora lifecycle Immutable OS layer

Runtime Dependencies

Component Version Pinned Notes
Go (services) 1.25 Yes (go.mod) 9 Go services
Python 3.12 Yes (Fedora 42 default) 6 Python services
llama.cpp Latest stable Via build LLM inference engine
Flask 3.x Via pip Web UI framework
cosign 2.4.x Via release workflow Image/artifact signing
Syft Latest stable Via CI SBOM generation

Inference Backends

Backend Model Format Supported Versions Notes
llama.cpp GGUF v3 header format Primary inference engine
Diffusers Safetensors HuggingFace format Image/video generation

Unsupported formats: Pickle (.pt, .pkl, .bin) — rejected by quarantine stage 2 (Format Gate) due to arbitrary code execution risk.

Support Windows

Release Support

Release Type Active Support Security Patches Notes
Current stable Full Full Latest vX.Y.Z tag
Previous minor Security only 6 months after next minor e.g., v1.2.x after v1.3.0 ships
Previous major None 12 months after next major e.g., v1.x after v2.0.0 ships

Feature Deprecation Policy

  1. Announce: Feature marked as deprecated in release notes and documentation
  2. Warn: Deprecated feature emits log warnings when used (minimum 1 minor release)
  3. Remove: Feature removed in next major version

Minimum deprecation window: 2 minor releases or 6 months, whichever is longer.

API Deprecation Policy

API Change Notice Period Backward Compatible
New endpoint Immediate Yes (additive)
New optional field Immediate Yes (additive)
Remove endpoint 2 minor releases No (removed in next major)
Change field semantics 1 minor release Aliased during transition
Policy schema change 1 major release Migration tool provided

Configuration Compatibility

Policy Schema

Schema Version Compatible Releases Migration
v1 (current) v1.x N/A
v2 (future) v2.x Migration tool + docs

Policy files (policy.yaml, agent.yaml) are validated at startup. Invalid policy files cause fail-closed behavior (all requests denied) rather than silent degradation.

Upgrade Compatibility Matrix

From → To Method Automatic Data Migration
Patch → Patch rpm-ostree upgrade Yes None
Minor → Minor rpm-ostree upgrade Yes None (new defaults)
Major → Major rpm-ostree upgrade + migration Semi-auto Per release notes
Rollback (any) rpm-ostree rollback Yes N/A (previous state)

End-of-Life Policy

When a release reaches end-of-life:

  1. No further security patches
  2. No bug fixes
  3. CI may stop testing against that version
  4. Documentation may reference newer versions only
  5. Users should upgrade to a supported release

Notification: EOL announcements are made at least 30 days in advance via:

  • GitHub Release notes
  • README update
  • Security advisory (if security-relevant)

Scope Boundaries

In Scope (Supported)

  • SecAI OS image and all bundled services
  • Policy configuration within documented schema
  • GPU acceleration for supported hardware (see matrix above)
  • Upgrade/rollback via rpm-ostree
  • Supply chain verification via cosign/SBOM
  • Incident response automation
  • Audit logging and integrity monitoring

Out of Scope (Not Supported)

  • Custom kernel modules or drivers not in the base image
  • Third-party services not bundled with SecAI OS
  • Model training (inference only)
  • Multi-node/cluster deployments (single-node appliance only)
  • Cloud provider integrations
  • Custom OCI image modifications (fork the recipe instead)
  • Performance tuning beyond documented configuration
  • Recovery from emergency panic level 3 (full wipe is unrecoverable by design)

Community-Supported

  • Non-standard GPU configurations
  • Exotic hardware (FPGA, custom accelerators)
  • Running in containers (not as a host OS)
  • Non-x86_64/ARM64 architectures
