GroqCloud Model Deployment for Open-Source LLMs

Stash, a US-based personal finance and investing platform, deployed Groq to power its AI agent network serving legal-compliance-aware Money Coach and investment features. Stash is legally obligated to act in users' best interests, requiring every AI interaction to pass rigorous compliance guardrails including pre-checks, data validation, post-checks, and outbound filtering at every layer of the pipeline. Challenge: Each compliance step required a separate round trip to the model, and with OpenAI's slower inference speeds, latency accumulated quickly, putting the entire real-time experience at risk. "With OpenAI, it was roughly 300 milliseconds just to start a request," said Stash's engineering lead Parrish. "When you're doing multi-step decision-making in real time, that becomes a serious problem. We had to pause some features that needed upfront validation. We even ran batch checks overnight to catch anything we missed." The team was forced to simplify by cutting agent reasoning steps, consolidating tasks into single prompts, and accepting tradeoffs in intelligence and safety assurance. Solution: Stash evaluated alternative AI providers and identified Groq as a standout. After extensive evaluation and nearly 80 emails exchanged with the Groq team, they integrated GroqCloud into the heart of their architecture. Today, Groq powers Stash's entire agent network, described as a "virtual company" working on behalf of each user. Built on GPT OSS 120B and GPT OSS 20B (with experimentation underway on Qwen), the Groq-powered network handles upfront decision-making, intelligent task routing, agent handoffs, compliance validation, and memory updates about each user. Results: "Before, we were using a mix of OpenAI and Gemini — OpenAI for intelligence, Gemini for speed," Parrish said. "With Groq and the OSS models, we're able to achieve the same level of intelligence at dramatically higher speeds. Now we can do 12 to 15 times the tasks we were doing before. And, we do this all with the highest standards of security and compliance." Within a week of switching on Groq in test mode, Stash saw measurable improvements and fast-tracked full implementation.
