Best Overall
Claude 3.5 Sonnet
Best coding, writing, and agent tasks at a reasonable price. Used by most production AI apps.
Best Budget
Gemini 1.5 Flash
$0.075/1M input tokens. Largest context window (1M). Ideal for high-volume, long-document tasks.
Best Reasoning
o1
Spends extra time reasoning before responding. Best for math, science, and multi-step logic problems.
Best Long Context
Gemini 1.5 Pro
1M token context window. Process entire codebases, books, or long videos in a single call.
Best Open Source
Llama 3.3 70B
Fully open, self-hostable. Competitive with GPT-4 class models. Available on Groq, Together AI, and locally.
Best Speed
GPT-4o Mini
Ultra-fast with multimodal support at $0.15/1M. Great for real-time apps, chat, and classification tasks.
Prices are approximate as of Q1 2025 and change frequently. Verify at each provider's official pricing page. Llama prices are indicative of cloud inference APIs (Together AI, Groq).
Frequently Asked Questions
Which LLM is the best overall?▼
It depends on your use case. GPT-4o and Claude 3.5 Sonnet excel at reasoning and code. Gemini 1.5 Pro has the largest context window. For budget, Gemini Flash and Claude Haiku offer the best value. Llama 3 is ideal for self-hosted / private deployments.
What does context window mean?▼
The context window is the maximum amount of text (in tokens) an LLM can read at once — including your prompt, conversation history, and its response. 1,000 tokens ≈ 750 words. Larger windows allow processing full documents or long conversations.
Why are prices listed per million tokens?▼
LLM APIs charge per 1 million tokens processed. Input (what you send) and output (what the model generates) have separate rates. Output tokens are typically 3–5x more expensive than input tokens.
Are these prices up to date?▼
Prices shown are approximate as of Q1 2025 and change frequently. Always verify on the provider's official pricing page before budgeting: platform.openai.com/pricing, anthropic.com/pricing, ai.google.dev/pricing.
What is multimodal support?▼
Multimodal models can process images, audio, or video in addition to text. GPT-4o, Claude 3.5, and Gemini 1.5 Pro all support image inputs. Some models also support audio and video.
