Key Features

      GroqCloud - Pros & Cons

      Pros

      • Time-to-first-token under a second changes the feel of conversational UIs
      • Drop-in OpenAI client compatibility — switching costs near zero
      • Pricing roughly 10x cheaper than frontier APIs for similar-quality open models
      • Whisper STT lets one provider cover both fast LLM and ASR for voice agents
      • Generous free developer tier for prototyping

      Cons

      • No frontier closed models (no GPT-4, no Claude, no Gemini)
      • Open-model catalog rotates — production code should pin and watch for deprecations
      • Rate limits on Free tier hit fast in heavy agent loops
      • Very long contexts reduce throughput compared to shorter prompts

      SGLang - Pros & Cons

      Pros

      • RadixAttention is a real throughput win for agent loops with shared prefixes
      • Constrained decoding makes JSON/tool-call output cheap
      • Often leads vLLM on DeepSeek MoE and structured workloads
      • Apache 2.0 — no license cost, fully self-hostable
      • OpenAI-compatible API means most client SDKs work unchanged

      Cons

      • Operational complexity higher than vLLM
      • Smaller ecosystem of third-party guides and integrations
      • Parallelism sharding is unforgiving — misconfigurations hurt throughput badly
      • Smaller managed-service ecosystem than vLLM
      • Documentation assumes prior inference-serving experience
