Groq
Pros
- + 800-1,000 t/s measured on GPT-OSS 20B, matching the published speed figure within about 15%
- + Per-model speed, price, context and rate limits are all published in one table — rare transparency
- + Document summarisation workload priced under $2 vs $10-20 on frontier APIs for the same task
- + Whisper transcription at $0.04/hr on turbo is the cheapest speech input I have priced
- + OpenAI-compatible API means switching cost is mostly a base URL
Cons
- - Nvidia's ~$20B asset deal (Dec 2025) left Groq restructuring as a neocloud; roadmap risk is real
- - Llama 3.3 70B and 3.1 8B appear priced publicly but 'Contact Sales / Enterprise' in the docs — unresolved conflict
- - 131K context ceiling is a fraction of what frontier APIs offer
- - Open-weight models lag frontier reasoning on my logic smoke tests
- - Self-serve catalogue is a handful of production language models, not a broad library
OpenAI API
Pros
- + Lowest false-call rate on my 250-case tool-use evaluation, including the deliberate no-call cases
- + Single account covers text, reasoning, image, audio, transcription, embeddings and agent tooling
- + Framework integrations were config-only where rival providers needed adapter code I had to maintain
- + Official pricing page documents wrinkles (residency uplifts, Fast mode rename) that others bury
- + Streaming response times were consistent enough over a week of monitoring that I stopped tracking them
Cons
- - Tool metering ($10/1k search calls, $2.50/1k tool calls) became about a fifth of my search-heavy prototype's bill
- - Entry rate limits are tight; my batch job triggered a 429 burst until spend tier rose
- - 10% uplift on regional data-residency and FedRAMP endpoints adds to an already premium price list
- - Specialised model lines (Rosalind trusted-access, cyber tier) assume institutional buyers
- - Catalogue churn makes third-party tutorials stale within months
