⚡ LLM API Pricing & Value Comparison 2026
📊 Understanding Token Pricing
LLM providers charge based on tokens, not words. A token is a small piece of text. As a rough approximation:
1 token ≈ 0.75 English words → 100 tokens ≈ 75 words → 1,000 tokens ≈ 750 words → 1M tokens ≈ 750,000 words.
For Indonesian and many Asian languages, the ratio varies but is generally similar.
The prompt + response together may consume around 50–100 tokens. When providers advertise prices such as "$0.10 per 1M input tokens," sending one million tokens costs only ten cents.
🏛️ Major LLM Providers in 2026
The market is currently dominated by four major providers: OpenAI, Anthropic (Claude), Google Gemini, and DeepSeek. Each occupies a different position in quality, speed, and cost.
💰 Cost Comparison per 1M tokens
| Provider | Model | Input Cost (per 1M tokens) | Output Cost (per 1M tokens) | Relative Quality |
|---|---|---|---|---|
| OpenAI | GPT-4.1 Nano | $0.10 | $0.40 | Medium |
| OpenAI | GPT-4.1 Mini | $0.40 | $1.60 | High |
| OpenAI | GPT-5 | $1.25 | $10.00 | Very High |
| Anthropic | Claude Sonnet 4.6 | $3.00 | $15.00 | Excellent |
| Anthropic | Claude Opus 4.6 | $5.00 – $15.00 | $25.00 – $75.00 | Frontier |
| Gemini Flash-Lite | $0.10 | $0.40 | Medium | |
| Gemini 2.5 Pro | $1.25 | $10.00 | Very High | |
| DeepSeek | DeepSeek V3.2 | $0.14 | $0.28 | High 🔥 |

📄 Real-world cost example: OCR Project
Suppose an OCR system processes 100,000 pages per month with average 1,000 tokens per page. Total monthly usage = 100 million tokens.
| Model | Estimated Monthly Cost (100M tokens) |
|---|---|
| DeepSeek V3.2 | ~$21 |
| Gemini Flash-Lite | ~$25 |
| GPT-4.1 Nano | ~$25 |
| GPT-5 | ~$560 |
| Claude Sonnet 4.6 | ~$900 |
💡 For OCR correction, text extraction, entity recognition, and translation, the cost difference becomes dramatic as volume grows. DeepSeek V3.2 delivers ~95% savings vs premium models.
