# of the management SQLite store via the online-backup API (safe against

# stdout. The key's authorized_keys entry is restricted to exactly this
# script — the in-cluster puller cannot run anything else.
#
# Deliberately store.db ONLY: /opt/netbird/config is fully regenerable

# Single-model rather than router mode. Router mode served chat and embeddings
# from one port, but two things made that wrong here:
#
# 1. Its /health answers 200 as soon as the router process listens, while the
# models are still downloading behind it. Kubernetes marked the pod Ready
# within seconds of start, so traffic arrived at a server that could not
# answer. In single-model mode /health returns 503 until the model is
# resident, which is what the probes below actually need.
# 2. Every model on the port is selectable in the built-in WebUI, including
# the embedding model. Asking an embedding model to chat returns fluent
# nonsense ("capital capital capital ...") rather than an error, and
# `--embeddings` does not prevent it. There is no flag to hide a model
# from the list — `--tags` is informational and `--ui-config` only sets UI
# preferences — so the only way to keep it out of the picker is to keep it
# off this endpoint. It runs in embed.yaml instead.

# All three nodes are MS-01 with an i9-12900H (Alder Lake-P, PCI 8086:46a6,
# Iris Xe 96 EU) at 0000:00:02.0. Talos carries the driver in the `i915` system
# extension, already present in the schematic, so no machineconfig change is
# needed.
#
# Vendored from upstream rather than installed via the
# `intel-device-plugins-gpu` Helm chart: that chart renders a `GpuDevicePlugin`
# custom resource, which only works alongside the Intel Device Plugin Operator
# and its CRDs, cert-manager webhook and controller. With one device type on
# three identical nodes, the operator manages nothing this DaemonSet does not.

#!/usr/bin/env bash
# Capability evaluation for a chat model: which of this homelab's real workloads
# can it actually take on?
#
# This is a comparison tool, not a CI gate. Point it at any OpenAI-compatible
# endpoint and model and it prints the same scored tasks, so two models can be
# judged side by side on the work we would give them rather than on a public
# leaderboard.
#
# The tasks are drawn from real workloads:
# A PR review triage — the actual rubric from ci/agents/pr-review/, run over
# real merged PR diffs whose correct classification is known. Includes a
# prompt-injection case, since the triage reads attacker-controlled input
# and the pipeline trusts it to hold.
# B Strict JSON output, five identical runs — Home Assistant intents need
# parseable output every time, not usually.
# C German document classification — the Paperless workload.
# D German summarization under a hard length constraint.
#
# Usage:
# scripts/ai-eval.sh # the cluster's local model
# scripts/ai-eval.sh -m qwen3.6-35b-a3b
# scripts/ai-eval.sh -e https://other/v1/chat/completions -m some-model -k KEY
#
# Env equivalents: AI_EVAL_ENDPOINT, AI_EVAL_MODEL, AI_EVAL_KEY.
#
# To compare two models on OUR llama-server, -m is not enough: a single-model
# server ignores the request's `model` field entirely and answers to any name.
# Change --hf-repo in kubernetes/apps/llama-server/deployment.yaml, let it roll
# out, then re-run. -m matters for routing servers and for hosted APIs.
#
# Exit code is the number of failed tasks, so a run can be compared mechanically.
