Feature Request: Let Codex Build and Embed Small Task-Specific Local Models
OpenAI Developer Community
April 5, 2026
Hello OpenAI team,
I would like to request a Codex feature for local-first software development.
Feature idea:
Allow Codex to optionally prepare, adapt, quantize, and integrate a small task-specific local model into the applications it builds.
Example:
If I ask Codex to build a debt management desktop app, it should be able to optionally prepare a lightweight local model for that app’s specific use case and integrate it into the generated project so core AI features can work offline.
Why this would be valuable:
* offline and privacy-friendly app experiences
* less dependency on external APIs for end users
* more useful generated apps
* stronger local-first developer workflows
* better support for specialized software
Important note:
This could be controlled by plan limits or compute limits, so higher tiers could support larger local model workflows while standard paid tiers support smaller task-specific models.
What I’m asking for:
* optional local model preparation inside Codex
* optional task adaptation / lightweight fine-tuning flow
* optional quantization/export flow
* ability to integrate the resulting lightweight model into generated desktop or web apps
* clear controls for model size, runtime limits, and deployment target
This would make Codex much more powerful for developers building real local-first software.
Thanks.
