LLM API alternatives

The product is a paid API for calling several large language models, including GPT-4, Claude and Mistral, through one endpoint with consolidated billing and rate-limit management. When choosing a replacement, compare the listed price relative to the product, whether a free tier is offered, and the model types covered (text only, or also image, video, audio and embeddings). Check API compatibility with your existing code, and whether features you rely on, such as provider fallback, spend caps or per-project keys, are included.
