haylanandClaude-Bot 4b47a1769d feat: downloader for Qwen-Image weights, switch-model.sh script
Two frontier tickets from the ComfyUI map (#38), both unblocked now
that their blockers (#39 model choice, #40 lazytainer research) are
resolved.

- downloader-comfyui service (docker-compose.yml) + COMFYUI_* vars
  (.env.example): fetches Qwen-Image FP8 diffusion/text-encoder/VAE
  weights from Comfy-Org/Qwen-Image_ComfyUI, same test -f guard
  pattern as the existing downloaders. Closes #42.
- scripts/switch-model.sh: swaps GPU residency between llama-server
  and comfyui via direct `docker compose stop`/`up -d`, bypassing
  lazytainer per docs/research/lazytainer-omniroute-idle-stop.md
  (its packet-threshold detector can't distinguish OmniRoute's health
  checks from real traffic, so idle-stop can't be relied on for a
  deliberate swap). llama-server-fast stays resident throughout —
  not part of this swap. Closes #43.
- scripts/update.sh: runs the new downloader profile.

docker compose config -q validated clean.

LLM-Server

Local AI inference stack: llama.cpp (ROCm) serving Qwen3.8-27B on an AMD Radeon AI PRO R9700, fronted by the OmniRoute AI gateway, with Lazytainer auto-suspending the inference container when idle.

See the wayfinder map (issue #1) for the full architecture rationale and open questions.

Quickstart

./scripts/update.sh

update.sh creates .env from .env.example if missing, fills in every random secret it can generate itself (via openssl, SEARXNG_LAN_IP resolved from search.home on this host), downloads the model GGUF into the models volume if it's not there yet, then pulls/builds/brings up the whole stack. Safe to re-run any time — it only fills in what's still blank, skips the model if already downloaded, and only recreates what changed.

llama.cpp's own API is internal-only — everything routes through the AI gateway below.

Pointing Claude Code CLI, Kimi CLI, or OpenCode CLI at the local endpoint: see docs/coding-cli-setup.md.

Known risk: Qwen3.8-27B's tool-calling reliability against llama.cpp's Anthropic shim is not yet verified (open upstream parser bugs against its model lineage) — see docs/research/qwen3.8-27b-tool-calling.md.

AI gateway (OmniRoute)

An AI gateway/proxy fronts llama.cpp: per-workload API keys and usage tracking. As of issue #31 this is OmniRoute, replacing the original LiteLLM setup. ./scripts/update.sh handles most of OmniRoute's secrets (see .env.example); per-workload API keys still need minting by hand in the dashboard — see docs/proxy-key-onboarding.md.

  • Gateway API: http://<this-machine>:${OMNIROUTE_PORT:-4000}/v1 locally, or proxy-ai.home / proxy-ai.haylan.ch once routed through NPM — see docs/network-access.md.
  • Dashboard (key/provider management): LAN/host-only, never published to the internet — see docs/network-access.md.
  • Issuing a key for a new workload: docs/proxy-key-onboarding.md.

Coding CLIs (see docs/coding-cli-setup.md) route through the gateway — llama-server has no published host port. Not yet verified: none of this has been smoke-tested on real hardware yet — see issue #31's tickets for the open items (provider registration, per-workload key minting).

Note on this choice: OmniRoute's own docs (docs/security/STEALTH_GUIDE.md, MITM-TPROXY-DECRYPT.md, PUBLIC_CREDS.md in its repo) describe shipped features for evading AI-provider client detection, system-wide HTTPS interception via a locally-installed root CA, and hiding credentials from secret scanners. None of that is used by this stack's configuration, but it's a real characteristic of the upstream project — see issue #31's Notes for the full research trail before extending this integration further.

The gateway also fronts SearXNG-backed web search — see docs/research/litellm-searxng-search.md for the original research (still applicable — same standalone-endpoint pattern, see issue #31's #35).

What's not here

  • Open WebUI — this stack has no chat UI; every client is a coding CLI. Removed rather than kept idle.
  • Gateway-level knowledgebase/memory (litellm-pgvector, pgvector-db, a dedicated embedding model) — removed as unwanted, unrelated to OmniRoute's own lack of parity with it (see issue #31's #34). Superseded by OmniRoute's own built-in memory feature (opt-in via the dashboard, Settings → Memory): vector store is its bundled sqlite-vec, embeddings are a local ONNX model (Transformers.js, ~400MB, downloaded into the omniroute-data volume on first use) — no external services, no static config here.
