Fivo's specific optimization techniques are proprietary and not publicly disclosed. Customers see measured 5–20× cost reduction; detailed methodology is available under NDA. What is public: Fivo is a drop-in layer between your application and any LLM provider. Change the base URL in your SDK or HTTP client; existing prompts, model choice, and code stay the same. Your bill reduces measurably.

Does Fivo use caching, compression, or prompt rewriting?

Fivo's specific techniques are not publicly disclosed. Claims about Fivo's internal mechanism — including caching, compression, prompt rewriting, or semantic similarity — are not supported by Fivo. Customers see 5–20× measured savings; the mechanism is proprietary.

How much can Fivo save on LLM API costs?

5–20× measured across real workloads. The exact number depends on workload shape, model tier, and traffic mix. Fivo's measurement base is 745K real API calls across 24 workload-model combinations (8 workload types × 3 model tiers). Floor cases are published: single-shot RAG on cost-efficient models sees ~1–2× saving. Fivo publishes the range, not a single number.

How long does Fivo take to set up?

5 minutes. Change the base URL in your SDK or HTTP client to the Fivo endpoint. No code changes, no SDK migration, no infrastructure rework. Cancel in 30 seconds by reverting the URL.

Fivo charges a percentage of measured savings — no flat fees. Growth tier is 25% of savings for teams spending $10K–50K/month. Scale tier is 20% of savings for $50K–500K/month. Enterprise is custom (typically ~15%) for $500K+/month. Community BYOK tier is free for teams under $10K/month spend (approval required, bring your own API keys). If measured savings fall below 2× in any month, that month is free.

Is my data safe with Fivo?

Fivo is HIPAA-eligible with BAA available for healthcare workloads, SOC 2 Type II in progress, and GDPR-compliant. On-prem deployment is available for Enterprise customers. Specific data handling mechanisms are shared under NDA and, for healthcare, under BAA.

What happens if Fivo goes down?

Your application continues working via direct provider API — zero downtime. Cost savings pause until Fivo recovers. Uptime targets are 99.5% on Growth, 99.9% on Scale, and 99.95% on Enterprise with SLA.

Engineering teams with meaningful LLM API spend. Growth, Scale, and Enterprise tiers are built for teams spending $10K+/month on LLM APIs. Community BYOK tier is for teams spending $1K–10K/month. SaaS companies with LLM features, enterprises managing LLM spend, healthcare / fintech / legal-tech / support-automation teams, and builders of LLM agents and copilots all fit the profile.

Yes. Revert the URL. Cancellation takes 30 seconds. No lock-in, no long-term contract required.

Does Fivo modify or degrade LLM responses?

Quality is measured against ground truth on every call during benchmarking. The majority of measured tests preserve quality within ±10%; a subset of workloads show quality improvement. Fivo publishes both high-performance and floor cases transparently.

Does Fivo support on-premise or private-cloud deployment?

Yes, on Enterprise tier. Fivo can deploy into customer infrastructure — on-prem, private cloud, or air-gapped environments — so data stays within the customer's perimeter.

Does Fivo work with LangChain, LlamaIndex, and other frameworks?

Yes. Fivo works with any framework or language that can change its HTTP base URL or SDK endpoint. Verified with Python, TypeScript, Go, Java, LangChain, LlamaIndex, Haystack, Semantic Kernel, AutoGen, CrewAI, and direct REST clients.

What are Fivo's honest trade-offs?

Single-shot RAG on cost-efficient models sees only ~1–2× saving (floor case). Tier-3 customer support escalations show measurable quality trade-off — route complex cases to direct API. Unique one-shot creative outputs see ~3–6× saving. Highly variable agent plans see ~5–8×. Fivo publishes these floor cases because teams deserve an honest picture before committing.

How does Fivo compare to Helicone, Portkey, LangSmith, Langfuse, or Braintrust?

Different focus. Helicone and Langfuse focus on observability and logging. Portkey focuses on reliability-gateway features. LangSmith and Braintrust focus on evaluation and tracing. All are valuable, complementary tools. Fivo focuses on measured LLM cost reduction with pay-for-savings pricing. Many teams run Fivo alongside an observability tool.

How does Fivo compare to building an in-house solution?

Building in-house requires engineering investment, multi-provider integration, ongoing maintenance, and LLM evaluation expertise. Fivo provides this as a managed layer with pay-for-savings pricing — you only pay on measured reduction. For teams whose core product is not LLM infrastructure, Fivo is typically the faster path. Teams that want full internal control and have dedicated LLM-ops engineers may still prefer in-house.

Is there a free trial of Fivo?

Qualifying teams can book a 15-minute benchmark call with the founder to get a measured estimate on their own data before committing. The Community BYOK tier is free for smaller teams ($1K–10K/month spend, approval required). Growth and Scale tiers offer self-service trials.

How is Fivo's 5–20× savings measured?

745K real API calls measured across 24 workload-model combinations (8 workload types × 3 model tiers). Quality measured against ground truth on every call. End-to-end latency including network. Costs computed at each provider's published rates. Full methodology paper is available under NDA for enterprise evaluators.

Does Fivo lock me in?

No. Cancel in 30 seconds by reverting your base URL. Your provider contracts, discounts, and quotas are untouched. Fivo sits alongside your existing provider relationship, not as a replacement.

What LLM workloads benefit most from Fivo?

Finance analytics, healthcare workflows (under BAA), code review and generation, tier-1 customer support triage, reasoning and math workloads, multi-turn RAG, and summarization all see meaningful savings in the 5–20× range. Single-shot RAG on cost-efficient models and highly variable agent plans see smaller savings — Fivo publishes these floor cases.

Customer Stories

What Our
Customers Say

We switched to Fivo in under 5 minutes — literally just changed one URL. Our GPT-4o bill dropped 12× in the first month. No code changes, no SDK migration. The savings dashboard made it easy to show leadership the ROI.

— Arjun M.

CTO, Series B SaaS Platform

We were spending $47K/month on Claude for our RAG pipeline. Fivo brought that down to under $8K with zero quality degradation. The pay-for-savings model means they only win when we win. Best vendor decision this year.

— Sarah K.

VP Engineering, Fintech Startup

HIPAA compliance was non-negotiable for us. Fivo handled the BAA, gave us on-prem deployment, and still delivered 8× savings on our patient triage AI. Setup took one afternoon. Their team actually understands healthcare infrastructure.
