<p>Provider selection is configured via
<code>HELIX_VISION_PROVIDER</code>:</p>
<ul>
<li><code>auto</code> — Probes all configured providers, uses
FallbackProvider</li>
<li><code>openai</code>, <code>anthropic</code>, <code>gemini</code>,
etc. — Use a specific provider</li>
<li><code>ollama</code> — Use local Ollama instance</li>
</ul>
<h3 id="local-model-support-ollama">Local Model Support (Ollama)</h3>
<p>The Ollama provider (<code>pkg/llmvision/ollama.go</code>) connects
to any Ollama instance:</p>
<ul>
<li>Configured via <code>HELIX_OLLAMA_URL</code> (e.g.,
<code>http://thinker.local:11434</code>)</li>
<li>Supports any vision model (e.g., <code>minicpm-v:8b</code>,
<code>llava:7b</code>)</li>
<li>Zero cost, no rate limits, full privacy</li>
<li>Auto-deployment via <code>pkg/remote/</code> ensures Ollama + model
are running on remote hosts</li>
</ul>
<h3 id="distributed-vision-llamacpp-rpc">Distributed Vision (llama.cpp
RPC)</h3>
<p>The <code>pkg/remote/</code> package manages distributed
inference:</p>
<ul>
<li><code>hardware.go</code> — Detects GPU (NVIDIA), CPU, and RAM on
remote hosts via SSH</li>
<li><code>llamacpp.go</code> — Manages llama.cpp RPC workers across
multiple hosts</li>
<li>Each worker contributes its VRAM/RAM to the inference pool</li>
<li>Configured via <code>HELIX_LLAMACPP_RPC_WORKERS</code> and
<code>HELIX_LLAMACPP_RPC_MODEL</code></li>
</ul>

<h2 id="thread-safety">Thread Safety</h2>
<ul>
<li>NavigationGraph uses <code>sync.RWMutex</code> for all
operations</li>
<li>FallbackProvider uses <code>sync.RWMutex</code> for provider list
access</li>
<li>All concurrent operations are race-detector safe</li>
</ul>
<h2 id="build-tags">Build Tags</h2>
<ul>
<li>Default build: No OpenCV, stubs return errors, LLM providers
work</li>
<li><code>vision</code> tag: Full OpenCV support via GoCV</li>
