Deep dive
The capability footprint differs most on vision: Gemini Robotics-ER 1.6 Preview, multimodal input: Gemini Robotics-ER 1.6 Preview, reasoning mode: Gemini Robotics-ER 1.6 Preview, function calling: Gemini Robotics-ER 1.6 Preview, tool use: Gemini Robotics-ER 1.6 Preview, and structured outputs: Gemini Robotics-ER 1.6 Preview. Both models share the core language-model surface, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.
Pricing coverage is uneven: Code Davinci 002 has no token price sourced yet and Gemini Robotics-ER 1.6 Preview has no token price sourced yet. Provider availability is 0 tracked routes versus 0. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Code Davinci 002 when coding workflow support are central to the workload. Choose Gemini Robotics-ER 1.6 Preview when reasoning depth are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
FAQ
Is Code Davinci 002 or Gemini Robotics-ER 1.6 Preview open source?
Code Davinci 002 is listed under Proprietary. Gemini Robotics-ER 1.6 Preview is listed under Proprietary. License labels affect whether you can self-host, redistribute weights, or rely only on hosted APIs, so confirm the upstream license before deployment.
Which is better for vision, Code Davinci 002 or Gemini Robotics-ER 1.6 Preview?
Gemini Robotics-ER 1.6 Preview has the clearer documented vision signal in this comparison. If vision is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for multimodal input, Code Davinci 002 or Gemini Robotics-ER 1.6 Preview?
Gemini Robotics-ER 1.6 Preview has the clearer documented multimodal input signal in this comparison. If multimodal input is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for reasoning mode, Code Davinci 002 or Gemini Robotics-ER 1.6 Preview?
Gemini Robotics-ER 1.6 Preview has the clearer documented reasoning mode signal in this comparison. If reasoning mode is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
Which is better for function calling, Code Davinci 002 or Gemini Robotics-ER 1.6 Preview?
Gemini Robotics-ER 1.6 Preview has the clearer documented function calling signal in this comparison. If function calling is mission-critical, validate it against the provider endpoint because model-level support and API-level exposure can differ.
When should I pick Code Davinci 002 over Gemini Robotics-ER 1.6 Preview?
Gemini Robotics-ER 1.6 Preview is safer overall; choose Code Davinci 002 when coding workflow support matters. If your workload also depends on coding workflow support, start with Code Davinci 002; if it depends on reasoning depth, run the same evaluation with Gemini Robotics-ER 1.6 Preview.
