Nex AGI: Nex-N2-Pro (free)

Nex-N2-Pro is a free text-and-image model from Nex AGI with a 262,144-token context window and a 256,000-token output ceiling. It supports tool use and reasoning, which puts it in the same functional tier as several paid alternatives. Structured output support is unconfirmed, so developers who depend on guaranteed JSON schemas should verify that separately before committing. The cost argument is straightforward: zero dollars per token at both input and output makes it worth testing for budget-conscious teams or solo developers doing early-stage work. The tradeoff is that no independent benchmark coverage exists yet, so there is no third-party evidence to compare its quality against competing models. Users who need verified performance data before deployment should treat it as unproven for now, while those comfortable running their own evaluations have little to lose by trying it.
