If you want frontier open-weight quality you pay for it; if you want free, there are 25 free models on the platform and several show up in this exact list.

Top picks

GLM 5.2

Ranks #1 on design_arena 3d (elo 1376), the best benchmark result of any model in this list. It's also the newest top-tier release here (2026-06-16), with a 1,048,576-token context window and $0.93/$3.00 per million input/output — OpenKey price $0.9579/$3.09 after the 3% fee.

DeepSeek V4 Pro

Rank 7 on design_arena 3d (elo 1327) at $0.435/$0.87 per million tokens — roughly half GLM 5.2's price for a top-10 3d result. 1M context. Good pick if you want near-frontier design benchmarks without the premium rate.

Nemotron 3 Ultra (free)

Same model, same benchmark (design_arena 3d rank 40, elo 1213) as its paid twin, but $0 in/out. 1,000,000-token context. If budget is the constraint and you can tolerate a rank-40 result instead of top-10, this is free capacity, not free-tier gimmick.

How to choose

First tradeoff: price per token vs. benchmark rank. GLM 5.2 sits at $0.93/$3.00 per million and rank 1 on design_arena 3d; DeepSeek V4 Flash is $0.09/$0.18 with a much lower rank (23) on the svg benchmark. Second: context window isn't free performance — GLM 5.2 and several Qwen3.5/Nemotron models offer 1M+ tokens, but a big window doesn't move the elo score. Third: free tiers (Nemotron 3 Ultra free, Laguna M.1 free, Gemma 4 free variants) usually mirror a paid model's exact benchmark — use them to test before committing spend, not as a permanent substitute if you need frontier rank.
