More about this project

Capability-aware Auto routing. Keep configured order for deterministic control, or explicitly enable Auto to prioritize already-configured models using measured capability evidence. Auto never infers capability from model names, and enabling Auto alone does not start benchmarks. - Verifiable model profiling. Exact Test Vision sends one request to one exact model; Quick and Full benchmark OCR / general / structured / document / grounding capabilities. Background profiling is separately authorized and yields to real foreground vision work. - Original pixels, real answers. The vision chain reads the image at original resolution (auto-downscaled only to protect latency/quota); the agent's question travels with the image, so answers are about your question, not a generic description. - Automatic failover with classified errors. Region blocks, ToS filtering, 402 quota, 429 rate limits, context overflow, network failures — the chain walks providers one by one and only reports after all of them failed, with actionable advice. A 429 immediately advances to the next backend and opens a Retry-After-aware cooldown instead of sleeping inside the request. - Image memory. Vision answers are cached by attachment content hash; later text turns substitute the recorded description (marked as untrusted evidence), so DeepSeek genuinely remembers earlier images without re-spending vision calls.…
