Which should you choose?
Which is better: Seed 1.6, Llama 3.1 Nemotron 70B Instruct or Gemma-SEA-LION-v4-27B-IT?
Seed 1.6 is the better all-round choice, scoring 55/100 against Llama 3.1 Nemotron 70B Instruct (45) and Gemma-SEA-LION-v4-27B-IT (39). It leads on inputs & features and context window. The score weighs price 50%, inputs & features 30%, context window 20%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, Seed 1.6, Llama 3.1 Nemotron 70B Instruct or Gemma-SEA-LION-v4-27B-IT?
Seed 1.6 is cheaper at $0.119 input / $1.19 output per million tokens (official Volcengine Ark API price). Gemma-SEA-LION-v4-27B-IT costs $0.351 input / $0.555 output per million tokens (median across 2 API providers); Llama 3.1 Nemotron 70B Instruct costs $0.478 input / $0.504 output per million tokens (median across 2 API providers; free on Nvidia). At a typical mix of three input tokens to one output token, that is $0.386 per million tokens for Seed 1.6 versus $0.402 for Gemma-SEA-LION-v4-27B-IT (1× as much) and $0.485 for Llama 3.1 Nemotron 70B Instruct (1.3× as much).
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Seed 1.6 has not been scored yet, Llama 3.1 Nemotron 70B Instruct has not been scored yet and Gemma-SEA-LION-v4-27B-IT has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Seed 1.6, Llama 3.1 Nemotron 70B Instruct and Gemma-SEA-LION-v4-27B-IT yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. Note that Gemma-SEA-LION-v4-27B-IT does not support tool calling, which most coding agents need.

Seed 1.6 accepts text; Llama 3.1 Nemotron 70B Instruct accepts text; Gemma-SEA-LION-v4-27B-IT accepts text. They handle the same number of input types.
Are any of these open source?
Llama 3.1 Nemotron 70B Instruct and Gemma-SEA-LION-v4-27B-IT publishes its weights and can be self-hosted; Seed 1.6 is proprietary.
Which is newer?
Seed 1.6 is the newest, released Oct 15, 2025. Gemma-SEA-LION-v4-27B-IT came out Sep 23, 2025; Llama 3.1 Nemotron 70B Instruct came out Apr 15, 2025.
How do you decide the winner?
Each model gets a 0–100 score on capability (50%, independent benchmark results); price (25%, blended price per million tokens (3 input : 1 output), log scale); inputs & features (15%, image, PDF, audio and video input, tool calling, structured output and reasoning); context window (10%, maximum tokens per request, log scale). Dimensions missing for any model are dropped and the remaining weights rescaled, so every model is judged on the same evidence. Specs and prices come from public model listings and the labs’ own API pages; capability scores come from independent benchmark runs. Data updated Oct 4, 2026.
