Model overview
The special offer group model is implemented by partially eligible accounts, using specific parameter requests to invoke Gemini 3.8 Flash. It has been confirmed that upstream traffic is indeed routed to Gemini 4. These are different checkpoints within Gemini 4; reportedly, b performs slightly better than a, but b currently has a lower level of reasoning. The exact IQ should be assessed through actual customer testing.
The summary below is compiled from sources by an AI model, not our own testing. Verify selection decisions against original sources and your workload.
Key features
- Supports multimodal input of text and images
- It is nominally based on the Gemini 4 architecture, and in actual measurements, it routes to different checkpoints within Gemini 4 (Argon a/b).
- Possesses reasoning capabilities, structured output, and tool invocation support.
Limitations & considerations
- Only eligible accounts can trigger it via specific parameters; not publicly available for general access.
- Argon b version currently has a low thinking level; its actual intelligent performance must be verified by the user.
- The official documentation does not provide clear performance benchmarks or specifications of capability boundaries.

Frequently asked questions
Is Gemini 4 Argon the officially released model?
No. This model is a non-public routing path, with requests directed to Gemini 4’s internal checkpoints via special parameters by a third-party platform, and it is not an independent model officially released by Google.
Why might the user experience vary across different users?
Because the actual routing depends on account eligibility, request parameters, and dynamic backend allocation, and because there are two undisclosed checkpoints with Argon a/b differences, response quality may fluctuate.
What is its relationship with Gemini 3.8 Flash?
Gemini 4 Argon must be triggered indirectly by “requesting Gemini 3.8 Flash with specific parameters,” essentially leveraging a compatible interface to access the underlying checkpoints of Gemini 4.
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
