How We Evaluate
Our reviews are based on publicly available documentation, API specifications, and benchmark results. We evaluate models across five dimensions:
- Context capacity — maximum input tokens and practical retrieval accuracy at scale.
- Output quality — coherence, factual accuracy, and instruction following based on published benchmarks.
- Pricing transparency — clarity of per-token costs, free-tier limits, and hidden fees.
- Multimodal breadth — native support for text, image, audio, and video inputs/outputs.
- Ecosystem maturity — SDK quality, documentation depth, and third-party integrations.
