Language Model APIs
Model reviews and comparisons covering context, tool use, coding workflows, pricing, and API access.
The language-model guides compare APIs by the work they need to perform, including structured output, tool use, coding, long-context processing, latency, and price. They avoid treating a single benchmark as a universal ranking. Use the articles to understand tradeoffs and the linked model pages to inspect current capabilities before selecting a model for an application or agent workflow.
