Auto-synced from OpenRouter — no editorial write-up yet.

GPT-5.4

Excellent general-purpose reasoning and broad world knowledge, with strong performance on coding, math, and multi-modal (image + file) inputs.

Output tokens are priced well above input tokens, so verbose responses dominate cost — tight max-token limits and prompt caching matter.
