How this service works
AI model capability, specs and limits table for 2,000+ LLMs — GPT-5, GPT-4o, Claude 5, Claude Sonnet, Gemini 3 Pro, Llama 4, DeepSeek V4 and more: context window size, max output tokens, vision/audio/function-calling/reasoning support. Compare model constraints side-by-side across every provider to pick the right model for long-context, multimodal, or tool-use workloads. Refreshed hourly.
Output
A table of 2,000+ LLM entries refreshed hourly, each row containing the model name, provider, context window size (in tokens), maximum output tokens, and boolean capability flags for vision, audio, function-calling, and reasoning support. Useful for programmatic model selection based on capability constraints.
Example use cases
Example prompt
“Show me a full comparison table of all LLMs — including context window size, max output tokens, and whether they support vision, audio, function-calling, and reasoning — so I can pick the right model for a long-context multimodal task.”
Technical details
Endpoint
GEThttps://modelprices.xyz/llm/limits?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to compare capability constraints (context window, max tokens, feature flags) across many models at once, rather than looking up a single model. Ideal for automated model-selection logic that must filter 2,000+ models by capability. Prefer over single-model lookup when the model name is not yet known and you need to search or filter the full catalog.
Side effects
- Payment not completed — 402 response if x402 payment header is missing or invalid
- Rate limit exceeded — too many requests in a short window
- Service temporarily unavailable — upstream data refresh failure
- Malformed response if query parameters are unexpected
