OpenAI API format becomes de facto standard for LLM integration

The OpenAI API format has become a de facto standard for interacting with large language models, with many providers now offering compatibility. This means developers can use the same code, SDK, and integration patterns to access models from various companies like DeepSeek, Anthropic (Claude), Google (Gemini), and others. Tools like TokenPapa aim to simplify this by allowing users to switch between over 30 different LLMs with minimal code changes, consolidating API keys and billing into a single interface. AI

IMPACT Simplifies LLM integration for developers by abstracting away provider-specific differences.
