📝 Walkthrough

Walkthrough

The PR adds two new members to the SupportedOpenAIModel enum: gpt-5.5 and gpt-5.5-pro. It also updates OpenAIChatNode's price_badge expression by inserting conditional branches for gpt-5.5-pro (usd: [0.03, 0.18] per 1K tokens) and gpt-5.5 (usd: [0.005, 0.03] per 1K tokens) before the existing gpt-5-* pricing branches.

744-753: 💤 Low value

Pricing values are correct; $contains ordering is correct.

Confirmed against OpenAI's official pricing page: gpt-5.5 is priced at $5 per 1M input tokens and $30 per 1M output tokens ($0.005/$0.030 per 1K — matches lines 751), and gpt-5.5-pro is priced at $30 per 1M input tokens and $180 per 1M output tokens ($0.030/$0.180 per 1K — matches line 746).

The branch order (gpt-5.5-pro before gpt-5.5) is correct: since "gpt-5.5" is a substring of "gpt-5.5-pro", reversing the order would misroute the pro model to the base pricing.

One minor forward-looking note: if gpt-5.5-mini or gpt-5.5-nano variants are introduced later, the current $contains($m, "gpt-5.5") branch would silently absorb them with pro pricing before any dedicated branches could be added. This is the same pattern used elsewhere in the expression (gpt-5, gpt-4.1, etc.), so it's consistent — just worth keeping in mind when adding sub-variants.

In `@comfy_api_nodes/nodes_openai.py` around lines 744 - 753, Pricing values and
ordering are correct, but to prevent future sub-variants (e.g., gpt-5.5-mini)
from being misclassified, tighten the gpt-5.5 branch condition: replace the
loose $contains($m, "gpt-5.5") check with a stricter matcher such as a regex
$match($m, "^gpt-5\\.5($|[^-])") or add a negative check like $contains($m,
"gpt-5.5") && !$contains($m, "gpt-5.5-"); keep the gpt-5.5-pro branch first and
leave its condition unchanged.

Looks like these models will be deprecated soon?
