antigravity: model ID 1417 (Gemini 4 Argon) reported as model_placeholder_m417 with no pricing #1893
Description
model_name_from_id in rust/adapters/antigravity/src/parser.rs has no entry for Antigravity model ID 1417 (Gemini 4 Argon). It falls through to the 1_000.. branch and is reported as model_placeholder_m417. That name isn't in the pricing catalog, so the cost is $0:
WARN Missing pricing for model_placeholder_m417; cost excludes this model.
gemini-4-argon is already in models-dev-pricing.json, so the fix is just the mapping:
1417 => "gemini-4-argon".to_string(),- ccusage 20.0.33 (
npx ccusage --breakdown), macOS - About 4.6M tokens unpriced (1.42M input, 30.6k output, 3.14M cache read). Rows Antigravity labels
gemini-4-argonby name are priced correctly. - IDs 1277 and 1050 also show up as placeholders (a few hundred tokens each); I don't know which models they are.
- Workaround:
pricingOverrideskeyed bymodel_placeholder_m417.

Pullfrog triage: priority:high
Kind: bug
Maintenance fit: maintainable
Confidence: high
Antigravity model ID 1417 falls through to model_placeholder_m417 with missing pricing warning and $0 cost for about 4.6M tokens. Verified parser.rs has no 1417 mapping and models-dev-pricing.json already contains gemini-4-argon, so this is a material cost misreport in existing supported behavior.
Decision: kept open; Pullfrog will attempt a focused implementation PR.
