Code Davinci 001 vs Gemini 3.5 Pro
Code Davinci 001 (2021) and Gemini 3.5 Pro (2026) compare a coding-specialized model against a standalone API model. Code Davinci 001 ships a not-yet-sourced context window, while Gemini 3.5 Pro ships a 2m-token context window. This page treats the result as workflow and deployment fit, not a universal model winner.
Treat this as a product-type comparison: Code Davinci 001 is coding-specialized model, while Gemini 3.5 Pro is standalone API model. Choose based on workflow fit before reading any benchmark or price row as decisive.

Deep dive
The capability footprint differs most on vision: Gemini 3.5 Pro, multimodal input: Gemini 3.5 Pro, and reasoning mode: Gemini 3.5 Pro. 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 001 has no token price sourced yet and Gemini 3.5 Pro 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 001 when coding workflow support are central to the workload. Choose Gemini 3.5 Pro 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. It also helps separate model capability from provider packaging, which can change cost and latency. For teams standardizing a stack, that distinction is often the difference between a benchmark win and a reliable deployment.
FAQ
Is Code Davinci 001 or Gemini 3.5 Pro open source?
Code Davinci 001 is listed under Proprietary. Gemini 3.5 Pro 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 001 or Gemini 3.5 Pro?
Gemini 3.5 Pro 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 001 or Gemini 3.5 Pro?
Gemini 3.5 Pro 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 001 or Gemini 3.5 Pro?
Gemini 3.5 Pro 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.
When should I pick Code Davinci 001 over Gemini 3.5 Pro?
Treat this as a product-type comparison: Code Davinci 001 is coding-specialized model, while Gemini 3.5 Pro is standalone API model. Choose based on workflow fit before reading any benchmark or price row as decisive. If your workload also depends on coding workflow support, start with Code Davinci 001; if it depends on reasoning depth, run the same evaluation with Gemini 3.5 Pro.
