Comparison
GPUBox vs Together.ai
Both serve open-source models behind an OpenAI-compatible API. The honest difference: catalog breadth vs jurisdiction. Together hosts hundreds of models in US infrastructure. We host a curated few in the UK.
If catalog breadth matters more than where the data lives, Together wins on that axis. If your stakeholders ask "is the inference happening in the UK?" and "adequate" isn't the answer they want, GPUBox is the answer.
