2026-10-13-gemini-cli-stable-v0-61-0-rewrites-explicit-flash-model-ids
Stable v0.61.0 rewrites explicit Flash model IDs. Since v0.61.0 the client rewrites an outgoing gemini-3.5-flash or gemini-3-flash model ID to gemini-3.8-flash, and gemini-3.1-flash-lite to gemini-3.5-flash-lite, when latest-Flash access is enabled. API-key, Vertex and Gateway auth return true for that gate in client code; Google login uses experiment flags. No exposed setting opts these exact IDs out of the mapping. This establishes request rewriting, not a measured served model or improved quality/latency. Other IDs pass through this table unless the separate experimental dynamic-model configuration changes resolution. The v0.61.0 narrative changelog omitted the mapping change while highlighting versioned-model preservation.
Channel: tagged-release. Half: both. Date: 2026-09-23.
Operator consequence: Re-baseline Flash evaluations when upgrading past 0.60.0, even if the configured ID is unchanged. Record the request and returned modelVersion separately; the latter was not observed here. Retaining 0.60.0 also retains this report’s older security/reliability defects, so it is not an unqualified remedy. Read preview cherry-picks rather than assuming every stable change had a week of preview exposure.
