RapidFire vs Google Cloud

Google Cloud runs your agents. RapidFire finds the version worth shipping.

The Gemini Enterprise Agent Platform, formerly Vertex AI, covers tuning, RAG, agents, and production optimization. Vizier runs one trial per worker, and RAG Engine runs a single retrieval configuration. RapidFire runs many configurations on shared hardware and compares retrieval setups side by side.

Where Google Cloud leads today

Where RapidFire goes further

RapidFire is strong here; Google Cloud is partial or not available.

Hyper-parallel execution

Hundreds to thousands of configurations sharing one machine's GPUs at once, not one job per worker

Strong1,000+ configurations run concurrently on a single multi-GPU machine, scaling out to a cluster.
Not availableTask-parallel only (one trial per worker); no hyper-parallel execution on shared hardware.

Live mid-run human steering

Stop, clone, or modify one running configuration without waiting for the batch

StrongIC Ops: stop, resume, or clone-and-modify any individual run from a live dashboard while it's still executing.
Not availableNo mid-trial steering described for Vizier or the Gen AI Evaluation Service.

Online aggregation of eval metrics

Stop an eval early, say at 20% of the data, with confidence intervals, instead of scoring the full set

StrongEvals are split into shards and partially aggregated live, with confidence intervals, so a decision can be made on a fraction of the eval set.
Not availableEvals process the full set.

Natural-language experimentation control (Action Bot)

Run or fully automate experiments in plain English, Do It For Me, Do It With Me, Do It Myself

StrongAn Action Bot steers experiments from plain-English instructions, with three selectable modes, Do It For Me (full automation), Do It With Me (alerts and drafted actions when something meaningful shows up), Do It Myself (manual control).
Not availableNo natural-language experiment control or selectable automation modes found.

Hybrid workflows

One pipeline mixing closed-API models and self-hosted open models

StrongA single pipeline can mix closed-API and self-hosted open models, and experiment across the mix.
PartialSupports both model types, but mixing them in one pipeline means stitching across separate services.

Explainability: what worked and what didn't

An exhaustive record of every configuration tried, so a team can show a result is the best its data and models allow

StrongBecause every configuration is run and logged, RapidFire can show what didn't work as well as what did, answering 'why only this accuracy?' with evidence.
Not availableLogs what was deployed or evaluated, not an exhaustive record of alternatives tried and rejected.

On-prem (customer-owned hardware)

Runs on hardware the customer owns, a hard requirement for many Fortune 500 buyers

StrongSelf-hosted on customer-owned GPUs, using Ray for distributed on-prem execution. Shipped data-layer integrations: Pinecone, Postgres (pgvector), FAISS.
Not availableCloud regions aren't on-prem; no deployment on customer-owned hardware.

Open core

An open-source core with proprietary layers on top, matters most to tech companies and tech-savvy enterprises that want to see the code

StrongOpen-source rapidfireai package, with a proprietary tier (RapidFireAI Pro) on top.
Not availableNo open core for these services.

GPU-efficiency focus

Explicitly optimizes GPU utilization, distinct from token-spend or trial-count savings

Strong5x cost reduction and up to 20x faster time-to-accuracy, plus '16-24x experimentation throughput on existing GPUs'.
Not availableVizier's efficiency is about running fewer trials, not GPU utilization.

Where Google Cloud leads today

Google Cloud is stronger here today.

Post-deployment monitoring & remediation

Keeps watching production after go-live; the strongest loops also fix what they find

RoadmapContinuous production monitoring with remediation proposed or applied automatically.
StrongGemini Enterprise Agent Platform's Agent Optimizer clusters real-world production failures and suggests refined instructions, plus continuous Agent Evaluation on live traffic.

On RapidFire's roadmap

Near-term, not yet shipped.

Automated eval creation

Generates eval metric code for a specific use case, instead of the user writing it

RoadmapToday users supply their own eval metric code. Converge Create aims to generate application-specific eval code from a plain-English description, drawing on a growing library of use cases.
Not availablePrebuilt generic metrics only; no generation of use-case-specific eval code found.

Where both are strong

Table stakes most buyers expect.

Experiment tracking & observability

Table stakes: live dashboards, run history, metric logging, buyers expect it everywhere

StrongMLflow-based dashboard with live per-run metrics and full run history.
StrongVertex AI Experiments plus Google Cloud observability tooling.

Task-parallel execution

Many independent jobs or trials run at once, spread across a cluster

StrongRuns configurations concurrently across GPUs and nodes, using Ray for distributed execution.
StrongVertex AI Vizier and custom training run trials in parallel.

Automated early-termination of losers

Kill weak configurations mid-run and reallocate their compute

StrongCore IC Ops behavior: stop weak configs automatically, reallocate freed compute to promising ones.
StrongVizier supports automated early stopping of unpromising trials.

End-to-end RAG pipeline

The whole retrieval pipeline, chunking, embedding, retrieval, reranking, generation, as one process. Comparing retrieval configurations is RapidFire-only.

StrongFull RAG pipeline in one script, and sweepable across many retrieval configurations at once. Retrieval-config comparison isn't available from any other vendor here.
StrongVertex AI RAG Engine provides an end-to-end RAG pipeline. Single configuration; no built-in comparison of retrieval configurations.

Fine-tuning / post-training

SFT, DPO, GRPO, and LoRA-adapter training runs

StrongExplicit support for SFT, DPO, and GRPO, with hyperparameter and LoRA-adapter experimentation across runs.
StrongVertex AI supports supervised and preference tuning.

Agent workflow execution

Running multi-step agent workflows with tool calls, table stakes, offered everywhere

StrongRuns agentic workflows, including tool calling, as part of experiments.
StrongGemini Enterprise Agent Platform runs agent workflows.

Audit trail / logging for compliance

Table stakes: logged runs and decisions for auditors, nobody gets off the ground without it

StrongEvery run, configuration, and result is logged.
StrongCloud Audit Logs and service-level logging.

Open + closed model neutrality

Doesn't care whether you use open models or closed APIs

StrongWorks with closed APIs and self-hosted open models alike.
StrongVertex Model Garden: 'hundreds of LLMs,' including Gemini, Llama, and Claude.

Customer VPC (cloud)

Deploys inside the customer's own cloud account

StrongDeploys in the customer's cloud account (e.g. the dedicated-VM RapidFireAI Pro setup).
StrongNative VPC deployment.

Using RapidFire with Google Cloud

RapidFire deploys in your own Google Cloud project and works with the open and closed models you already call there. Find the winning configuration with RapidFire, then run and monitor it on Google Cloud.
