Best OpenAI Models for AI Writer (Gutenberg Sidebar)

1. What AI Writer Needs #

Your AI Writer:

• Works in the Gutenberg editor.
• Generates:
  • Draft blog posts/pages.
  • Rewrites paragraphs.
  • Summaries or expansions.
• Needs:
  • High text quality.
  • Ability to handle long context (full articles).
  • Good style control for tone and SEO.

So we prioritize quality + long context more than raw speed.

2. Recommended Models #

Primary recommendation for AI Writer:

1. gpt-4.1
   • OpenAI’s top non-reasoning model, with up to 1 million tokens of context. Reuters+3OpenAI+3OpenAI Platform+3
   • Great for:
     • Long article drafting.
     • Rewriting large sections with consistent style.
     • Complex SEO-driven structure.

Balanced, cheaper alternative:

2. gpt-4.1-mini
   • Still very strong; cheaper and faster than full 4.1. OpenAI Platform+1
   • Ideal if you:
     • Write many posts.
     • Want good quality without the cost of full 4.1.

Fast outline / brainstorming option:

3. gpt-4.1-nano
   • Good for:
     • Quick outlines.
     • Idea lists, bullet points. OpenAI Platform+1
   • Less ideal for final polished drafts; better used for “first pass”, then refine with 4.1/4.1-mini.

Fallback options:

4. gpt-4o / gpt-4o-mini
   • If your project still uses them and 4.1 isn’t available, they remain solid general-purpose text models. OpenAI Platform+2The Verge+2
5. gpt-3.5-turbo
   • Only if nothing else is available; quality and coherence are noticeably weaker for long-form content vs 4.x. OpenAI Platform+1

3. Models Not Recommended for AI Writer #

• Reasoning models (o1, o3, o3-mini, o4-mini):
  • Excellent at complex math/logic, but:
    • Slower.
    • More expensive.
  • Overkill for general content writing and could make your costs explode for long drafts. Roboflow Blog+3OpenAI Platform+3OpenAI+3
• Old GPT-3-style base models (davinci/curie/etc.):
  • Largely superseded by GPT-4.x and GPT-3.5/GPT-4.1 lines. OpenAI Platform+1

4. How to Set the AI Writer Model in Davix #

The AI Writer module uses its own settings page (Pro-only).

1. Go to Davix AI Engine → AI Writer.
2. Find the field labeled “AI Writer model” or similar.
3. Set:
   • gpt-4.1 (recommended), or
   • gpt-4.1-mini (cheaper/balanced), or
   • gpt-4.1-nano (fast outline mode).
4. Save.
5. Open any post in Gutenberg:
   • Open the Davix AI Writer sidebar.
   • Run a test: generate an outline or rewrite a paragraph.

If drafts fail to generate:

• Check:
  • OpenAI key.
  • Model name spelling.
• Enable AI Writer debug logs (we described this in the Debug Logs section) and reproduce the error.
