On the same V4 Pro model, QuickSilver Pro is $0.435 / $0.87 per 1M tokens versus Together's current $1.74/$3.48 rate — 80% lower on both input and output. The official V4 Flash 0731 build is $0.112 / $0.224 versus Together's $0.14/$0.28, 20% lower on both legs.
Change base_url from api.together.xyz/v1 to api.quicksilverpro.io/v1 and swap the API key. Model ID mappings: deepseek-ai/DeepSeek-V4-Pro -> deepseek-v4-pro.
If you fine-tune custom models, reserve dedicated GPU endpoints, use Llama or Mistral, or need embeddings — we do not serve those. Image generation we do: Gemini 3 Pro Image and FLUX.2 Pro.
Yes for chat: streaming, tools, json_schema, usage.cost all work through the official OpenAI SDK.
