Market and catalogue signals · secondary, never the language Index rank
The bounded 0–100 capability score blends each source’s competitive placement with its published achievement, then combines capability families. Evidence breadth adds a modest uncertainty adjustment; price and popularity are not part of benchmark-led rank.
Market Gravity uses OpenRouter’s full-catalogue popularity order. Sparse Vercel top-ten observations appear only when published and do not affect the score.
How does GPT-4o (2024-05-13) rank among AI models?
GPT-4o (2024-05-13) is a superseded version and is not on the current board as of 22 September 2026. Its archive position, where one exists, is shown on the page; the newer version carries the current rank.
How much does GPT-4o (2024-05-13) cost per 1M tokens?
GPT-4o (2024-05-13) is listed at $5.00 per 1M input tokens and $15.00 per 1M output tokens as of 22 September 2026 across 2 providers. Prices come from the OpenRouter catalogue and re-observe on every refresh. For 1,000 requests using 2,000 input and 500 output tokens each, the listed rates imply $17.50 total (2M input + 0.5M output). This excludes caching, batch discounts, prompt-length tiers, tool charges and retries; verify the chosen endpoint's rate and limits before budgeting.
What is the context window of GPT-4o (2024-05-13)?
GPT-4o (2024-05-13) has a published context window of 128K tokens (128,000) and a maximum output of 4K tokens. Individual providers can serve less than the published maximum; the providers table lists each endpoint's own limit.
Is GPT-4o (2024-05-13) open-weight?
