Compare LLM APIs by model quality, input/output price, cached and batch discounts, context, multimodal support, tool calling, hosting choices, privacy, and eval workflow.
Start with the use case: for Product team needing one broad default, pick ChatGPT; for Document-heavy reasoning workload, pick Claude; for Google Cloud or Workspace-aligned team, pick Gemini; for Developer choosing open-model infrastructure, pick Replicate.
OpenAI is the broadest product/API default when modality and tooling breadth matter.
Pick ChatGPTClaude is the better shortlist item for long-context reasoning and careful writing.
Pick ClaudeGemini fits teams already comparing Google pricing, models, and multimodal docs.
Pick GeminiReplicate is the practical hosted-model API path when infrastructure should disappear.

The best LLM APIs for Apps, Agents, Open Models, and Multimodal Workloads include ChatGPT, Claude, Gemini, Hugging Face, Replicate, and Mistral Models. LLM API choice is a workload decision. OpenAI/ChatGPT is the broad multimodal/product default, Claude is the long-context reasoning row, Gemini is strong for Google pricing and multimodal workflows, while Hugging Face, Replicate, and Mistral/open-model paths matter when hosting and model choice are the point.
Normalize cost by input tokens, output tokens, cached input, batch discounts, tools, search, audio, containers, and failed/retried calls. Use provider docs for current model names and prices; LLM API pricing changes fast enough that stale tables can mislead buyers. Evaluate privacy, training defaults, data retention, region, eval tools, rate limits, and support before moving production traffic. For open-model hosting, compare Hugging Face, Replicate, Mistral/open-weight, and local LLM paths instead of assuming one frontier API fits every workload.
Product team needing one broad default → ChatGPT; Document-heavy reasoning workload → Claude; Google Cloud or Workspace-aligned team → Gemini; Developer choosing open-model infrastructure → Replicate.
