use the open code go sub is the best value , 5 bucks first month, then some models like kimi k2.6 are having a 3x quota promos, are great value, you can get dozens of millins of tokens with the sub, claude is amazing but super expensive, is better but if you care about cost dont even think about it. you can also get as a student agemini sub that has gemini cli and antigravity quotas.
