1. What the Chatbot Needs from a Model #
Your Chatbot:
- Runs interactive, multi-turn conversations.
- Needs good instruction-following and stable tone.
- Must be fast enough for live chat.
- Might run many requests per day, so cost matters.
So, we need a model that balances:
- Quality (good answers, less hallucination).
- Latency (fast response).
- Price.
2. Recommended Models (Priority Order) #
Based on OpenAI’s docs and current model lineup: OpenAI Platform+3OpenAI+3OpenAI Platform+3
Best default choice for Chatbot:
gpt-4.1-mini- Very strong instruction following and tool-calling, with 1M-token context. OpenAI Platform+2OpenAI Platform+2
- Cheaper and faster than full
gpt-4.1, but still much smarter than earlier 4o/3.5 models. - Great for general support chat, Q&A, and your historic / technical content.
High-quality premium choice:
gpt-4.1- OpenAI’s flagship non-reasoning model, designed to outperform GPT-4o with better long-context and coding performance, while also being cheaper than older GPT-4.x. OpenAI+2OpenAI Platform+2
- Great if:
- You want maximum quality.
- You serve fewer users but care a lot about answer depth and nuance.
High-volume / cheapest choice:
gpt-4.1-nano- Smallest, fastest, and cheapest member of the 4.1 family; still supports long context. OpenAI+2OpenAI Platform+2
- Ideal if:
- You have many chatbot sessions per day.
- You prefer a very low cost over maximum intelligence.
Legacy / fallback options (if 4.1 not available in your account):
gpt-4o-miniorgpt-4o- GPT-4o and 4o-mini are powerful multimodal models; 4.1 series is designed to outperform them, but they may still be present in your account and your plugin docs probably refer to them. The Verge+3OpenAI+3OpenAI Platform+3
- Use if:
- Your account doesn’t expose GPT-4.1 yet.
- Or you already tuned prompts for GPT-4o.
gpt-3.5-turbo(last resort)- Now considered legacy and generally weaker than 4o/4.1 mini; up-to-date guidance from OpenAI suggests using 4.1 or 4o-mini instead for new workloads. OpenAI Platform+2OpenAI Platform+2
- Only use if:
- Your budget is extremely tight.
- Or your account/region does not support newer models.
3. Models You Should Avoid for Chatbot #
- Reasoning models like
o1,o3,o3-mini,o4-mini:- Designed for complex reasoning tasks, math, STEM, etc. Roboflow Blog+3OpenAI Platform+3OpenAI+3
- They often:
- Take longer per response.
- Cost more per token.
- Overkill and expensive for typical customer/user chat on your site.
- Obsolete / deprecated versions (e.g. older GPT-3.x or early 4.0 snapshots).
- OpenAI deprecates old model versions regularly; new models are cheaper and better. OpenAI Platform+2Portkey+2
4. How to Set the Chatbot Model in Davix #
- Go to Davix AI Engine → Chatbot.
- In the OpenAI settings section, find:
- “Chatbot model” or similar (this field is already documented in your earlier docs).
- Enter one of the recommended model IDs, e.g.:
gpt-4.1-minigpt-4.1gpt-4.1-nano
- Save changes.
- Open the chat bubble on the front-end and test.

If you get “model not found” errors:
- Your OpenAI project may not have access to that model yet.
- Try a different one from the recommendations list.
