Reviewer scorecard
“RadixAttention and constrained decoding are powerful features. Performance benchmarks are competitive with vLLM.”
“Cheapest way to run Llama and Mistral models in production. The inference speed is competitive with major providers. OpenAI-compatible API makes switching easy.”
“Impressive research but smaller community than vLLM. The frontend language is interesting but adds complexity.”
“The pricing is genuinely good and reliability has improved. The fine-tuning workflow is straightforward. A solid choice for open-source model deployment.”
“Constrained decoding and structured generation are the future of reliable LLM outputs. SGLang leads here.”
“Together is betting that the future is open-source models. As Llama and Mistral improve, inference providers like Together become the AWS of AI.”
