I just learned today that opencode zen have deepseek v4 flash for free

WTF, I could just use the expensive ai models of opencode go for planning, writing specs and then use opencode zen deepseek v4 flash max for implementation. I am loving this opencode, loving the freebies

DeepSeek V4 Flash Free in OpenCode Zen

OpenCode Zen - Big-Pickle and DeepSeek V4 Flash Free still rate limited after 24h + paid $20. Anyone know the reset window?

Hit the free tier limit on both 'big-pickle' and \`deepseek-v4-flash-free\` yesterday. Still getting \`FreeUsageLimitError\` today. I've since funded the account with $20 (paid models work fine), but the free model remains locked.

Does the free tier reset daily, weekly, or is it a one-time cap per account? Anyone know the actual reset window?

So I Created a new Account on opencode and trying to use opencode api key with a curl it shows 429 FreeusageLimitError but when I use same api key with opencode IDE in terminal, it works. Can somebody tell how to fix it ? I am using the free models like deepseek-v4-flash free and minimax m2.5 free
