FAQ: AMPLbot#

What is AMPLbot?#

AMPLbot is a specialized AI assistant for optimization modeling with AMPL and AMPL+Python workflows, available as a custom GPT on ChatGPT.

It helps you learn AMPL, draft models from natural language, debug formulations, and build optimization applications with amplpy.

Is AMPLbot free?#

Yes. You can access it here: AMPLbot on ChatGPT.

What can AMPLbot help me with?#

AMPLbot supports the full modeling lifecycle:

  • Learn AMPL syntax, installation basics, and modeling patterns.

  • Formulate LP, MIP, NLP, MINLP, CP, and multi-objective models from plain-language descriptions.

  • Build AMPL+Python applications and data pipelines using amplpy.

  • Diagnose infeasibility, unboundedness, and solver errors.

  • Improve performance with reformulations and solver-option guidance.

What makes AMPLbot different from other LLMs?#

AMPLbot is focused on AMPL and optimization workflows. It is designed to produce practical AMPL and amplpy guidance for modeling, debugging, and deployment-oriented use cases.

How do I get started with AMPLbot?#

Open AMPLbot on ChatGPT and start with prompts like:

“Quick guide on how to use AMPL”

or

“Help me formulate this optimization problem in AMPL and build a Python app around it.”

Is AMPLbot able to help with complex models?#

Yes. It is useful for large and complex models, but it is still important to validate assumptions and test the resulting model carefully.

Does AMPLbot execute optimization code?#

No. AMPLbot helps you model and write code, but it does not run your optimization jobs.

Do I need AMPL installed to use AMPLbot?#

No. You can use AMPLbot directly in ChatGPT without a local AMPL installation.

Is AMPLbot always accurate?#

AMPLbot is often effective for AMPL-related tasks, but like any LLM it can make mistakes. Review outputs critically, especially for production use.

How can I send feedback about AMPLbot?#

You can:

I don’t want to use AMPLbot. Any alternatives?#
