Which should you choose?
Which is better: Laguna XS.2, Gemini Robotics-ER 1.6 Preview or Nemotron 3 Nano Omni 30B A3B Reasoning?
Nemotron 3 Nano Omni 30B A3B Reasoning is the better all-round choice, scoring 68/100 against Gemini Robotics-ER 1.6 Preview (64) and Laguna XS.2 (36). The score weighs inputs & features 60%, context window 40%. None of the shared benchmarks cover every model here yet, so capability is left out of this verdict.
Which is cheaper, Laguna XS.2, Gemini Robotics-ER 1.6 Preview or Nemotron 3 Nano Omni 30B A3B Reasoning?
Nemotron 3 Nano Omni 30B A3B Reasoning is cheaper at $0.25 input / $0.85 output per million tokens (median across 4 API providers; free on Nvidia). Gemini Robotics-ER 1.6 Preview costs $1.00 input / $5.00 output per million tokens (median across 1 API provider). At a typical mix of three input tokens to one output token, that is $0.40 per million tokens for Nemotron 3 Nano Omni 30B A3B Reasoning versus $2.00 for Gemini Robotics-ER 1.6 Preview (5× as much). Laguna XS.2 has no published per-token price.
Which scores higher on benchmarks?
There is no independent benchmark that covers all three models yet. Laguna XS.2 has not been scored yet, Gemini Robotics-ER 1.6 Preview has not been scored yet and Nemotron 3 Nano Omni 30B A3B Reasoning has not been scored yet.
Which is better for coding?
There are no published SWE-bench Verified results for Laguna XS.2, Gemini Robotics-ER 1.6 Preview and Nemotron 3 Nano Omni 30B A3B Reasoning yet, so there is no like-for-like coding score. Test both on a sample of your own tasks. All three support tool calling for agent workflows.
Which has the bigger context window?
Laguna XS.2 has the largest context window at 262,144 tokens, against 256,000 for Nemotron 3 Nano Omni 30B A3B Reasoning and 131,072 for Gemini Robotics-ER 1.6 Preview. Maximum output per response: Laguna XS.2 up to 32,768, Gemini Robotics-ER 1.6 Preview up to 65,536, Nemotron 3 Nano Omni 30B A3B Reasoning up to 65,536 tokens.
Which can read images, PDFs, audio or video?
Laguna XS.2 accepts text; Gemini Robotics-ER 1.6 Preview accepts text, images, audio and video; Nemotron 3 Nano Omni 30B A3B Reasoning accepts text, images, audio and video. Gemini Robotics-ER 1.6 Preview handles the widest range of inputs.
Are any of these open source?
Laguna XS.2 and Nemotron 3 Nano Omni 30B A3B Reasoning publishes its weights and can be self-hosted; Gemini Robotics-ER 1.6 Preview is proprietary.
Which is newer?
Laguna XS.2 is the newest, released Apr 28, 2026. Nemotron 3 Nano Omni 30B A3B Reasoning came out Apr 28, 2026; Gemini Robotics-ER 1.6 Preview came out Apr 14, 2026. Knowledge cutoff: Gemini Robotics-ER 1.6 Preview Jan 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.
