问题背景

gemini-4-hydrogen 引入了新的 -xhigh 思考档位后缀（gemini-4-hydrogen-xhigh），但上游同步源（如 models.dev / litellm）仅包含裸模型名 gemini-4-hydrogen。

目前 database/model_pricing_override.go 中的 antigravityCanonicalPricingModel 仅剥离 "-high", "-medium", "-low", "-tiered"，导致 gemini-4-hydrogen-xhigh 无法映射回 gemini-4-hydrogen 继承同步定价（仍回落为 $1/$2 默认价），而同系列的 -low / -medium / -high 均可正常同步为 $1.50/$0.075/$7.50。

修改内容

• database/model_pricing_override.go：在 antigravityCanonicalPricingModel 的 gemini- 后缀列表中加入 "-xhigh"（置于 "-high" 之前）。
• database/model_pricing_override_test.go：补充 gemini-4-hydrogen-xhigh 在 TestPricingManagementModelKeyPreservesIndependentAlias 与 TestAntigravityPricingAliasInheritance 中的测试用例。

测试验证

go test ./database -run 'TestPricingManagementModelKeyPreservesIndependentAlias|TestAntigravityPricingAliasInheritance' -v

以上用例全部 PASS。

Walkthrough

Gemini pricing canonicalization now strips the -xhigh suffix. Tests cover the management key, alias target, and inheritance of synced prices from the base model.

Changes: Gemini xhigh pricing alias

Layer / File(s)	Summary
Canonicalization and price inheritance database/model_pricing_override.go, database/model_pricing_override_test.go	Canonicalization strips the -xhigh suffix. Tests verify that gemini-4-hydrogen-xhigh remains a management key, aliases to gemini-4-hydrogen, and inherits its synced input, output, and cache-read prices.

Explanation

The title names the actual change: the Antigravity Gemini alias mapping now recognizes the -xhigh suffix. The raw summary confirms that antigravityCanonicalPricingModel now strips -xhigh for Gemini models, and the tests cover the gemini-4-hydrogen-xhigh alias inheritance. The title is specific, concise, and free of file lists or vague terms.
