Together AI → QuickSilver Pro

The steps

1. 1

   Get a QuickSilver Pro API key

   Sign up at quicksilverpro.io/dashboard. First top-up bonus: we match your first top-up 100%, up to $50 — added to your balance when you top up again (any amount from $5).

2. 2

   Change the base URL

   In your OpenAI SDK init, swap the base_url.

   - base_url="https://api.together.xyz/v1"
   + base_url="https://api.quicksilverpro.io/v1"

3. 3

   Swap the API key

   Replace your Together token with a QuickSilver Pro key.

   - api_key=os.environ["TOGETHER_API_KEY"],
   + api_key=os.environ["QSP_KEY"],

4. 4

   Rename model IDs

   Together prefixes model IDs with the originating org. Drop the prefix and use the QuickSilver Pro short name.

   Together AI	QuickSilver Pro
   deepseek-ai/DeepSeek-V4-Pro	deepseek-v4-pro

5. 5

   Test your core flows end-to-end

   Run one representative request for each feature you use — chat, streaming, tool / function calling, and json_schema strict mode. Apart from the known difference below, any behavioral difference is a bug — report it.

   One known difference: json_schema strict mode is model-dependent. The Claude models do not support it, so a schema there is advisory and the enforced path is a tool with strict: true — structured output.
