📝 Walkthrough

Walkthrough

This PR adds four new OpenAI GPT-5.6 model variants (base, Sol, Terra, Luna) to the configuration's chatgptApiModelKeys and Models mappings, adds corresponding English locale entries, and extends existing unit tests for config predicates, token parameters, and model name conversion to cover the new keys.

High-Level Assessment

The following are alternative approaches to this PR:

1. Data-driven model registry + derived test coverage

• ➕ Reduces repetitive updates across config, locale keys, and multiple test lists
• ➕ Makes it harder to forget adding a new model to one of the representative arrays
• ➖ Higher up-front refactor cost for a simple additive change
• ➖ May complicate explicit ordering/presentation logic if the UI relies on curated lists

2. Auto-generate locale model labels from model IDs

• ➕ Eliminates duplication between i18n strings and model registry descriptions
• ➖ Harder to localize non-English strings later if labels are no longer explicit i18n entries
• ➖ May produce less polished names (capitalization/tier naming) without manual curation

Recommendation: The PR’s explicit additions are consistent with the existing pattern and are appropriate for a small change. If model tiers continue to expand frequently, consider a follow-up to centralize preset definitions and derive representative test lists (and possibly UI labels) from that single source to avoid drift.

Pull request overview

This PR updates ChatGPTBox’s OpenAI (API) model presets to include the GPT‑5.6 family, exposing both the documented base alias (gpt-5.6) and the tiered variants (Sol/Terra/Luna) so they appear correctly in the UI and remain covered by existing model-name and token-parameter behaviors.

Changes:

• Added GPT‑5.6 preset keys to the OpenAI (API) model list and Models registry.
• Added English i18n labels for the new GPT‑5.6 presets.
• Expanded unit tests to cover model-name descriptions, config predicates, and token parameter selection for the new model IDs.
