Best OpenAI Models for Forms (AI Replies & Auto Emails)

1. What the Forms Module Needs #

Your Forms module:

• Generates shorter, focused responses:
  • Auto replies.
  • Email content.
• Often runs on many submissions (e.g. contact forms).
• Needs:
  • Good instruction following.
  • Low cost per request.
  • Stable formatting for emails / templated replies.

2. Recommended Models for Forms #

For Forms, we prioritize cheap + fast, but still need good quality.

Best default for Forms:

1. gpt-4.1-mini
   • Excellent instruction following.
   • Strong general reasoning.
   • Large context (1M tokens) – good if you include form context and long historical prompt. OpenAI Platform+2OpenAI+2
   • Good balance of quality vs cost.

High-volume / low-cost option:

2. gpt-4.1-nano
   • Fastest and cheapest 4.1 model; ideal if you have many forms submissions per day. OpenAI+2OpenAI Platform+2
   • Great for:
     • Simple auto-acknowledgements (“Thanks, we received your request…”).
     • Short, templated replies.

Premium option for important business forms:

3. gpt-4.1
   • Use if certain forms require:
     • Rich, detailed responses.
     • More nuance or sensitivity (e.g., complex support forms). OpenAI+1

Legacy / fallback:

4. gpt-4o-mini or gpt-4o
   • Solid if you already use them or if 4.1 is not yet available. OpenAI Platform+2Zapier+2
5. gpt-3.5-turbo
   • Only if you have no access to the 4.x family or are extremely budget-sensitive. OpenAI Platform+1

3. Models to Avoid for Forms #

• Heavy reasoning models (o1, o3, etc.):
  • Overkill for simple contact form replies; slower and more expensive. OpenAI Platform+2OpenAI+2
• Very old / deprecated models:
  • Might disappear or be redirected, causing unpredictable behavior over time. OpenAI Platform+1

4. Save changes.
5. Submit a test form and check:
   • AI reply.
   • Email generated content (if Auto Email is enabled).
