Groq Cloud API
Ultra-fast LLM inference API powered by custom LPU (Language Processing Unit) hardware delivering 300-500+ tokens/second for Llama, Mixtral, and Gemma models.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
Simple API key auth, no scope granularity. Data sent to Groq servers — review data handling policies for sensitive workloads.
⚡ Reliability
Best When
You need the fastest possible inference for open-weight models (Llama 3.x, Mixtral) and latency is a critical constraint for your agent.
Avoid When
You need proprietary frontier model quality, very long contexts, or guaranteed enterprise uptime — use OpenAI, Anthropic, or cloud providers instead.
Use Cases
- • Real-time agent reasoning loops where latency matters — Groq delivers 10-50x faster tokens than GPU inference
- • Interactive voice AI applications requiring <200ms response time using Groq's low-latency inference
- • High-throughput batch inference for agent evaluation pipelines needing fast model calls
- • Streaming code generation where token-by-token speed dramatically improves UX
- • Fallback inference layer for latency-sensitive agents when primary model is slow
Not For
- • Proprietary frontier models (GPT-4o, Claude, Gemini) — Groq only serves open models
- • Agents needing large context windows >128K tokens (Groq has smaller context support)
- • Production workloads requiring enterprise SLA — Groq is still scaling infrastructure
Interface
Authentication
API key as Bearer token. OpenAI-compatible: set base_url to api.groq.com/openai/v1 and use OpenAI SDK.
Pricing
Significantly cheaper than OpenAI for comparable open model quality. Rate limits are the main constraint on free tier.
Agent Metadata
Known Gotchas
- ⚠ Tool calling is supported but model quality for tool use varies — Llama 3.3 70B is best for structured tool calls
- ⚠ Context window limits vary by model — verify max_tokens before using for long-document agents
- ⚠ Free tier RPM limits are very low (30 RPM) — production agents hit limits quickly; upgrade before deploying
- ⚠ Model availability changes frequently as Groq adds/removes models — check available models list before hardcoding model IDs
- ⚠ Response streaming is fast but first-token latency still applies — don't assume zero latency even at 500+ tokens/second
