Multi-Model Cost Comparison Tool
This tool lets you paste a single prompt and instantly see the estimated cost across all major LLMs. Token counts vary by model because each uses a different tokenizer — GPT-4o uses the o200k_base tokenizer, Claude uses Anthropic's custom BPE tokenizer, and Gemini uses SentencePiece with a 256K vocabulary.
Key Takeaways from Model Pricing
- DeepSeek V3 is typically the cheapest API-available model with GPT-4-class quality.
- GPT-4o-mini & Gemini Flash are best for high-volume tasks needing fast, cheap responses.
- Claude Opus 4 & GPT-4 are the premium options — best for complex reasoning and creative tasks.
- Gemini 1.5 Pro has a very large context window (1M tokens) and competitive pricing.
