Verdict & Recommendation for Developers
For Complex Code & Agent Workflows: Claude 3.5 Sonnet remains the developer preference due to its high architectural adherence and precise function call parameter execution.
For Low-Latency Interactive Chat & Vision: GPT-4o delivers the fastest decoding speed (84.1 t/s) and lowest frontier TTFT (275ms), making it ideal for consumer chat apps and vision parsing.
For Large Codebases & Multimedia: Gemini 1.5 Pro’s 2-million-token context window allows developers to ingest entire repositories or multi-hour audio/video transcripts at half the price of GPT-4o.
With API100, developers do not need to choose a single vendor. You can route coding requests to Claude, streaming chat to GPT-4o, and document ingestion to Gemini using the same API key and wallet.
