|
| Customization & Branding |
-
Designed as an internal tool with its own UI, so only minimal branding tweaks (logo/colors) are available.
-
No white-label or domain-embed options—Pyx lives as a standalone interface rather than a widget on your site.
-
The look and feel stay “Pyx AI” by design; public-facing brand alignment isn’t the goal here.
-
Emphasis is on security and user management over front-end theming.
|

- Lets you shape the AI’s persona and tone using pre-prompts and system instructions.
- Uses domain allowlisting to ensure the chatbot appears only on approved sites.
|
| LLM Model Options |
-
Doesn’t expose model choice—Pyx likely runs GPT-3.5 or GPT-4 under the hood, but you can’t switch or fine-tune it.
-
No toggles for speed vs. accuracy; every query uses the same model configuration.
-
Focuses on its RAG engine with a single, undisclosed LLM—less flexible than tools that let you pick GPT-3.5 or GPT-4 explicitly.
-
No advanced re-ranking or multi-model routing options are mentioned.
|
- Pick GPT-4o-mini for speed or full GPT-4o for deeper answers. Model options
- Select the mode per chatbot, balancing response time against depth as you like.
