OpenCode Go doubles Gemini 4 Argon Contributor monthly limits to $60 and $240 through November 30

OpenCode Go added Gemini 4 Argon Contributor to its model list and doubled that model's monthly allowance through November 30. During the promo, the Go plan's allowance for this model goes from $30 to $60, and Go Plus goes from $120 to $240.

What you can use

Gemini 4 Argon Contributor is available on both Go and Go Plus. Token pricing is about $4 per million input tokens, $20 per million output tokens, and $0.20 per million cached reads, in line with public rates. The promo doubles the included monthly dollar allowance for this model; it does not cut the per-token price in half again.

The Contributor suffix means prompts and completions may be used to train future Google models, and the model is not ZDR. If your project cannot accept training use, pick another non-Contributor model on Go.

Allowance size

On the $10/month Go plan, this model has a $60 monthly allowance, so $10 buys $60 of usage.

On the $40/month Go Plus plan, this model has a $240 monthly allowance.

The 2x allowance runs through November 30. Limits still roll across the usual 5-hour, weekly, and monthly buckets. After you hit the cap, enabling balance fallback spends Console credits; otherwise you can keep working on free models that are still in a free window.
