Prefer GeminiConfig.fromValues, which validates the values, normalises baseUrl and resolves contextWindow and reserveCompletion from the bundled model catalogue. The constructor is private: build one with the companion apply and adjust it with the with* setters. Java and Kotlin, which cannot see Scala default arguments, use GeminiConfig.apply(apiKey, model) and the setters, so adding a field never breaks them.
Value parameters
apiKey
Google API key; redacted in toString.
apiKeyProvider
asked for the key on every request instead of sending apiKey, so a rotated key is used without rebuilding the client (#2477): a section's apiKeyFile sets one
Model's total token capacity (prompt + completion combined).
googleSearch
whether to ground answers in Google Search: the section's googleSearch key. When set, every request carries Gemini's google_search tool, the model may search before answering, and the sources it used arrive on Completion.citations. Off by default; billed by Google.
model
Model identifier, e.g. "gemini-2.0-flash".
reserveCompletion
Tokens held back from prompt history for the completion.
timeouts
how long a request and a stream may take: the section's timeouts block. An absent value keeps the client's own default (ProviderTimeouts)
The endpoint this config will contact, when it is known statically.
The endpoint this config will contact, when it is known statically.
Used by policy checks and diagnostics that need to know where traffic will go without knowing which provider it belongs to. None means the config carries no single URL — not that it makes no network calls.
The same config, its client asking provider for the key on each request, so a rotated key is used without rebuilding the client.

The loader calls this for a section that sets apiKeyFile. The default returns this: a config whose client cannot take a provider ignores it, and its apiKeyProvider stays None - which the loader reports as an error for apiKeyFile and code setting a provider should check. A config that supports it overrides this with its own return type.
The same config with the given proxy and TLS settings.
The same config with the given proxy and TLS settings.
The loader calls this on every config a descriptor builds, as it does withTimeouts, so a descriptor does not read the http block itself. The default returns this: a config that does not carry the setting ignores it. A config that does overrides this with its own return type.
The loader calls this on every config a descriptor builds, passing the section's timeouts block, so a descriptor does not read the block itself. The default returns this: a config that does not carry timeouts, such as one supplied by another module, ignores them. A config that does overrides this with its own return type.
