Together AI → QuickSilver Pro
Both APIs speak the OpenAI chat-completions shape, so the move is a base-URL swap. QuickSilver Pro serves the latest DeepSeek V4 wave — V4 Flash for low-cost chat and V4 Pro for premium reasoning — well below Together's own-GPU rates. For the full side-by-side analysis, see /vs/together-ai.
The steps
- 1
Get a QuickSilver Pro API key
Sign up at quicksilverpro.io/dashboard. Launch bonus: top up between $5 and $50 and we match it 100% — pay $5, get $10; pay $50, get $100.
- 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
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
Rename model IDs
Together prefixes model IDs with the originating org. Drop the prefix and use the QuickSilver Pro short name.

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. Any behavioral difference is a bug — report it.
