Strengths & Best Use Cases

Nano Banana 2

Google

1. High-efficiency counterpart to Gemini 3 Pro Image

Google describes Nano Banana 2 as the high-efficiency counterpart to Gemini 3 Pro Image.
Optimized for speed and high-volume developer use cases rather than maximum pro-grade fidelity.

2. Native image generation + understanding

Accepts text and image inputs and can output both text and images in a conversational workflow.
Useful for quick iteration, editing, remixing, and interactive visual applications.

3. Strong throughput with practical image controls

Supports up to 14 input images per prompt, 128 k input tokens, and 32,768 output tokens.
Handles multiple aspect ratios and can generate or edit images while keeping latency and cost lower than higher-end image models.

4. Grounded, developer-friendly image workflows

Supports Google Search grounding and Content Credentials (C2PA) for image outputs.
All generated images include SynthID watermarking as part of Google's native image stack.

Claude 4.5 Sonnet

Anthropic

1. Best-in-class coding performance

#1 on SWE-bench Verified (77.2% standard, 82.0% high-compute).
Excels at debugging, architecture, and multi-file code generation.
Maintains coherence for extremely long tasks (30+ hours).

2. State-of-the-art computer use & agents

Leads OSWorld at 61.4%.
Strongest model for agentic workflows, multi-step tool use, and real computer control.
Powering Claude Code, the new Claude Agent SDK, and Chrome agent actions.

3. Advanced reasoning & math

Large improvements across reasoning-heavy benchmarks (AIME, MMMLU, τ2-bench, Terminal-Bench).
Deep multi-step reasoning with extended or interleaved thinking.

4. High alignment & safety

Most aligned Claude model to date with reduced deception, hallucinations, sycophancy, and harmful compliance.
Strong protections against prompt injection for agentic tasks (ASL-3 safeguards).

5. Domain-expert performance

Notable gains in finance, law, medicine, and STEM tasks.
Trusted by early customers for long-context legal analysis, multi-file engineering, security research, and red-teaming.
