# Hermes Ollama Models
|
|
|
|
Native-like Hermes dashboard plugin for local Ollama model management and chat.
|
|
|
|
## Chat capabilities
|
|
|
|
- Select an installed Ollama model and load it into memory
|
|
- Chat through Ollama's native `/api/chat` endpoint
|
|
- Attach screenshots and JPEG/PNG/WebP images for vision-capable models
|
|
- Attach text PDFs; PDF text is extracted with `pypdf`
|
|
- Add public HTTP/HTTPS URLs for HTML/text, images, or PDFs
|
|
- View live host RAM and swap statistics
|
|
- View Ollama's loaded-model memory split: total, GPU VRAM, and normal RAM/offload
|
|
- View NVIDIA GPU telemetry when `nvidia-smi` is available
|
|
- Chat is the default view when the Ollama Models plugin opens
|
|
- Natural composer behavior: Enter sends; Shift+Enter creates a new line
|
|
- Paste images directly into the composer and drag/drop images, PDFs, and text files
|
|
- Streamed Ollama responses with a real Stop action that cancels the active request
|
|
- Minimized-by-default expandable thinking/progress details with live stage, elapsed time, event, and character counters
|
|
|
|
The chat transcript and selected model are persisted in the Hermes server's SQLite database at `~/.hermes/ollama-manager/chat.sqlite3`, so conversations can be listed and resumed from another browser or after a dashboard restart. Use **New conversation** to start a separate thread and **Clear chat** to delete the selected shared conversation. Uploaded files remain temporary; attachment names/types/URLs are retained as metadata, not raw file contents.
|
|
|
|
## Performance metrics
|
|
|
|
Each completed request records Ollama-provided counters and timing when available:
|
|
|
|
- Time to first token (TTFT)
|
|
- Total request latency
|
|
- Prompt/input token count and prompt tokens/sec
|
|
- Output token count and output tokens/sec
|
|
- Total tokens
|
|
- Ollama total/load/prompt-evaluation/generation durations
|
|
- Model, request status, request ID, and error details
|
|
|
|
The dashboard shows per-conversation metrics and rolling aggregates across the latest 100 requests. Values are shown as unavailable when Ollama does not provide them; the plugin does not estimate token counts.
|
|
|
|
## Catalog and download filters
|
|
|
|
The Popular and Available downloads views only show models with known size and expected RAM estimates that fit the running host's installed RAM, detected from `/proc/meminfo` and reported in the API filter metadata. The limit is calculated at runtime, so it follows RAM upgrades or downgrades without a hard-coded threshold. Available downloads also includes known fitting variants from installed model families.
|
|
|
|
The Available downloads controls support:
|
|
|
|
- Dense or MoE model type
|
|
- Abilities such as completion, thinking, tools, vision, audio, and video when supplied by the catalog
|
|
- Organization by upstream popularity, newest (`modified_at`), smallest size, largest size, or name
|
|
- Search across model names, families, strengths, and capabilities
|
|
|
|
Popularity and date ordering use upstream metadata only; the plugin does not invent popularity, dates, RAM requirements, or token metrics.
|
|
|
|
## Installation
|
|
|
|
This plugin is installable from the Hermes dashboard Plugin Section using the repository URL:
|
|
|
|
```text
|
|
https://gitea.beyondcloud.solutions/dennii/Hermes-Ollama_Models.git
|
|
```
|
|
|
|
In Hermes Dashboard, open **Plugins**, choose **Install from repository**, enter the URL above, and install. The repository contains the root `plugin.yaml`, dashboard manifest, backend API, compiled frontend bundle, stylesheet, and an opt-in prerequisite declaration. On Linux, the Hermes installer will verify Ollama, install it with the official Ollama installer when missing, and install the plugin's `pypdf` dependency before committing the plugin into `~/.hermes/plugins/`. Ollama installation needs root or passwordless `sudo`; if the host cannot provide that, the plugin install stops without enabling a partially configured plugin. After installation or an update, restart only the Hermes dashboard service if requested by the installer.

|
## Security limits
|
|
|
|
- Uploaded files are limited to 20 MiB each
|
|
- Fetched URLs are limited to 15 MiB and a 30-second timeout
|
|
- Private, loopback, link-local, reserved, multicast, and unspecified URL targets are blocked, including redirect destinations
|
|
- Remote documents are inserted as untrusted content, not system instructions
|
|
- Only locally installed models can be selected or loaded; chat does not download models
|
|
|
|
## Dependency
|
|
|
|
The Hermes Plugin Section installs the declared `pypdf` dependency automatically before the plugin is committed. For a manual checkout, install it with:
|
|
|
|
```bash
|
|
pip install -r requirements.txt
|
|
```
|
|
|
|
`pypdf` is required for text-based PDF extraction. Scanned/image-only PDFs need OCR and are not converted to text by this plugin.
