Nex-N2-Pro — Nex multimodal model with an Intelligence Index of 41, a 400K-token context window and a blended price of $0.43/1M tokens (open weights).
Gemini 3.1 Flash-Lite vs Nex-N2-Pro: Nex-N2-Pro scores higher on the Intelligence Index. Nex-N2-Pro leads overall capability (Intelligence Index 41.0 vs 28.0). Gemini 3.1 Flash-Lite is the cheaper model to run at $0.22/1M blended tokens — about 2.0× cheaper.
Capability: intelligence, coding and agentic work
On the composite Intelligence Index the Nex-N2-Pro scores 41.0 versus 28.0. For software development, the Coding Index puts Nex-N2-Pro ahead (59.1 vs 34.7). On agentic, multi-step tool-use tasks, Nex-N2-Pro measures stronger. Composite indices summarize many evaluations, but always test on your own workload before committing.
Context window and speed
The Gemini 3.1 Flash-Lite accepts up to 1 million tokens per request, which sets how much documentation, transcript or code it can reason over at once. In measured throughput, Gemini 3.1 Flash-Lite generates faster (278 vs 142 tokens/s), which matters for interactive apps and high-volume pipelines.
Pricing and access
At blended per-token rates, Gemini 3.1 Flash-Lite is the cheaper model to run ($0.22 vs $0.43 per 1M tokens). Gemini 3.1 Flash-Lite is proprietary api and Nex-N2-Pro is open weights. Open-weight models can be self-hosted, trading per-call cost for infrastructure you manage; for production also weigh rate limits, throughput and data-residency requirements.
The verdict
Both are credible choices in the ai model comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Large language models are compared on independent leaderboard metrics: an Intelligence Index (a composite of reasoning and knowledge evaluations), Coding and Agentic indices where measured, community arena Elo, maximum context window, a blended API price per million tokens (weighted across cache-hit, input and output rates), and measured output speed in tokens per second. Where a model ships multiple reasoning-effort variants, we report its strongest variant. Benchmarks capture only part of real-world quality, which also depends on tool use, latency, safety and task fit — and this space moves quickly, so figures reflect the leaderboard snapshot on the page date.
