GPT-5.2 Codex vs Nano Banana Pro

1. Optimized for Long-Horizon Coding Tasks

• OpenAI describes GPT-5.2 Codex as a highly intelligent coding model built for long-horizon, agentic coding work.
• Well suited to planning, refactoring, debugging, and multi-step implementation flows inside real codebases.

2. Adjustable Reasoning for Coding Work

• Supports configurable reasoning effort from low to xhigh depending on speed and quality needs.
• Accepts both text and image inputs while producing text output.

3. Large Context + Long Output

• 400 k token context window supports broad repository understanding and larger working sets.
• Allows up to 128 k output tokens for longer patches, code generation, and technical explanations.

4. Up-to-Date Model Snapshot

• Knowledge cut-off of Aug 31 2025 keeps it current with newer tools and frameworks.
• Supports streaming, function calling, and structured outputs for tool-driven coding workflows.

1. Studio-quality image generation

• Built on Gemini 3 Pro for exceptionally high fidelity.
• Improved accuracy in composition, physics, lighting, and artistic style.

2. Precise creative controls

• Fine-tune lighting, camera, color grading, focus, and physical realism.
• Ideal for professional production workflows requiring creative direction.

3. Advanced text rendering & localization

• Produces crisp, accurate text inside images (signs, menus, labels, UI elements).
• Can localize text across different languages while preserving layout and style.

4. Multi-input creative workflows

• Supports up to 14 reference images for composite ads or mockups.
• Generates consistent resemblance for up to 5 individuals.
• Works with 2K and 4K resolution outputs.

5. Strong world knowledge
