Groq API
Hacker ApprovedRanked 2 of 12 LLM inference APIs by recommenders
People recommend Groq for very fast, cheap model inference, especially open models like gpt-oss and Kimi K2. The most common caveat is inconsistent latency and reliability.

Very fast LLM inference
“When you use Cereberas (or Groq) to develop an API, the turn around speed of iterating on jobs is so much faster”
Comment from 25 Feb 2026 in “Mercury 2: The fastest reasoning LLM, powered by diffusion” “Its inferencing speeds are faster than those of H200s, and it has the lowest costs in the industry.”
Comment from 25 Dec 2025 in “Nvidia buying AI chip startup Groq for about $20B in cash” “Many hundreds of tokens per second of output is the norm, in my experience.”

Low cost per token
“they offer something different to most other providers (cheaper, faster, and until recently "we don't store your data by default")”

Runs large open models quickly
“I use them heavily in production because OSS 120B on Groq/Cerebras is one of the fastest models available”
Comment from 1 Mar 2026 in “Switch to Claude Without Starting Over” “They're running much larger models (orders of magnitude) and still reaching competitive speeds.”
Comment from 29 May 2026 in “Real-time LLM Inference on Standard GPUs: 3k tokens/s per request” “Currently the best performance I can get is the gpt-oss models on Groq or Cerebras”

Low latency for voice and pipelines
“We use Groq with gpt-oss-20b, which gives great results and only adds ~250ms to the processing pipeline.”
Comment from 25 Dec 2025 in “Using Vectorize to build an unreasonably good search engine in 160 lines of code” “TTFT with Groq and colocation are both real wins that don't get talked about enough”
Comment from 3 Mar 2026 in “Show HN: I built a sub-500ms latency voice agent from scratch” “inference is finally fast enough to be in the system loop”

What people warn about
Each mark is one comment
Inconsistent latency and reliability
“Groq is very fast, but the latency wasn't always consistent and I saw some very strange responses on a few calls”
Comment from 3 Mar 2026 in “Show HN: I built a sub-500ms latency voice agent from scratch” “My company had a really terrible experience trying to use Groq, and I would NOT recommend anyone use their service if you need reliability.”
Comment from 2 Jun 2026 in “How the hell is Groq raising more money?” “response times would vary so wildly that it just about erased any benefit in their throughput”
Comment from 2 Jun 2026 in “How the hell is Groq raising more money?” Suspected quantization and caching issues
“It is certainly fast, but I think there might be some caching issues somewhere.”
Comment from 20 Feb 2026 in “The path to ubiquitous AI (17k tokens/sec)” “I could swear they were doing some problematic quantization”
Comment from 24 Dec 2025 in “Nvidia buying AI chip startup Groq for about $20B in cash” “they are quantizing the models underneath. And they dont even disclose it.”
Comment from 2 Jun 2026 in “How the hell is Groq raising more money?” Few recent models supported
“Their website doesn't list them as offering any models that were released recently.”
Comment from 2 Jun 2026 in “How the hell is Groq raising more money?” “The problem with groq was they only allowed LORA on llama 8b and 70b”
Comment from 22 Feb 2026 in “How Taalas "prints" LLM onto a chip?”

“Groq has always been more efficient than Cerebras at running very small models”
“I agree that Groq with multilayer hybrid bonding could be a good idea.”
“Default (embedded) provider is Groq, because when I start the project, was the best free API service for AI.”
“response times would vary so wildly that it just about erased any benefit in their throughput”
“they were still extremely fast, which is still incredibly useful”
