Google Gemini API vs GPT vs Claude vs DeepSeek: Best Model Comparison

Introduction

Selecting the right large language model (LLM) is no longer just about choosing the most hyped name—it’s about measurable ROI, operational fit, and vendor reliability. CTOs and engineering managers increasingly face cross-vendor deliberations as Google Gemini, OpenAI GPT, Anthropic Claude, and DeepSeek all position themselves for enterprise adoption.

Evaluation Criteria

Vendor Coverage

You’ll need to compare:

• Google Gemini API – Google’s flagship multimodal model
• OpenAI GPT – Mature ecosystem with consistent updates
• Anthropic Claude – Safety-first design with strong conversational capabilities
• DeepSeek – Research-heavy focus on reasoning depth

Performance Dimensions

Key benchmarks to consider:

• Latency: Time from request to completion
• Factual Accuracy: Reliability in delivering correct information
• Reasoning Depth: Ability to perform complex, multi-step problem solving
• Code Generation: Quality and correctness of produced code

Cost Efficiency

Review both input and output token costs:

• OpenRouter vs Wisdom-Gate: Wisdom-Gate rates are notably lower in many cases
• Example Savings:
  • GPT-5: ~20% lower via Wisdom-Gate
  • Claude Sonnet 4: ~30% lower
  • gemini-3-pro: ~30% lower

Integration Ease

Check for:

• Uniform REST endpoints
• Quality documentation
• SDK coverage for your languages

Real-World Benchmark Results

Test Setup

• Unified prompt set to measure summarization, reasoning, and code generation
• API platform: Wisdom-Gate
• Endpoint example:

curl --location --request POST 'https://wisdom-gate.juheapi.com/v1/chat/completions' \
--header 'Authorization: YOUR_API_KEY' \
--header 'Content-Type: application/json' \
--data-raw '{
  "model": "gemini-3-pro",
  "messages": [{"role": "user", "content": "Hello, how can you help me today?"}]
}'

Latency Findings

• Fastest: GPT-5
• Close second: DeepSeek
• Gemini and Claude slightly longer due to processing for multimodality/safety layers

Accuracy & Consistency

• Claude leads in low hallucination rates
• GPT a close second with broad-topic reliability
• Gemini showed strength in multimodal reasoning
