Giga vs Vapi (2026)

Agents carry out transactions in the business's systems inside the conversation, issuing refunds, updating accounts, applying discounts and managing subscriptions, and send follow up emails. Giga does not publish the list of supported systems.

Function tools call the customer's server logic, and API Request tools call any HTTPS API directly with credentials held by reference. MCP tools connect an assistant to external MCP servers at runtime. Built in tools transfer calls, end calls, send SMS and press DTMF keys, and prebuilt integrations include Google Calendar event creation, Make and n8n. Deepgram, OpenAI and other providers are model layers, not integrations.

Agent Canvas defines support rules and multi step workflows in plain language for voice, chat or multimodal agents, deploys them through versioned, git synced releases, and Scout, a second agent, reads conversations and proposes and tests changes to the first.

Squads split a call across specialized assistants that hand off to each other through handoff tools with declared destinations, resolved at runtime. Context passing, variable extraction and rejection rules are all configurable, and the squad examples route callers by verification and inquiry type. Vapi's older Workflows builder has been retired and its flows moved to Squads.

Inbound calls, chats, emails and messages (SMS, WhatsApp, iMessage) from the business's customers start the agent without anyone at the business prompting it, and the agent sends follow up emails that carry the conversation's context.

Outbound campaigns carry a schedulePlan with an earliest and latest dispatch time, so Vapi starts dialing a contact list on its own schedule, with pre dial webhooks. Assistant hooks run actions on call events. Agents also answer on Vapi, Twilio, Telnyx and SIP numbers, in web calls and over SMS chat.

Each agent has a knowledge base that the CLI and SDK manage alongside agents and deploys, and Scout drafts agents from the business's policies and knowledge. How retrieval works is not public. A managed, updatable knowledge base points to a maintained retrieval layer, though Giga does not say so.

SourceGiga, giga.ai CLI post (14 Jul 2026) and Scout pageread 2026-09-28

Knowledge bases are the customer's uploaded files, such as txt, pdf, docx, csv, md and more, added through the dashboard or the file API, kept in Vapi and attached to assistants. During a call the query tool searches them by file ID, with Google Gemini models doing the retrieval, and new knowledge is added by uploading a file instead of retraining. A custom knowledge base can swap in the customer's own retrieval server.

Context carries across channels and conversations for each customer, so a customer who called yesterday and chatted this morning gets an email that picks up where they left off. That context is kept per customer, though Giga gives no lifetime or delete path for it.

For chat and SMS, a sessionId groups chats under one persisted conversation that expires 24 hours after creation by default (expirationSeconds). Sessions can be read in session logs and deleted through the API, and within a call, squads carry context across handoffs. Nothing the agent learns about a caller is kept beyond the session.

Scout tests only safe changes on a slice of traffic and routes risky ones to human review, and nothing it proposes goes live until the team approves it. The Browser Agent takes control of a website only with the user's approval, and the user can stop it at any time. Teams also set when the agent answers, asks a question or hands off to a person.

A tool rejection plan attaches conditions to any tool and blocks the call when the recent conversation state matches them, and handoff rejection rules block unwanted transfers between assistants. Transfer tools hand a caller to a person by blind or warm transfer. There is no approval step that holds an action until a person signs off, so escalation hands over the whole conversation.

Giga reports SOC 2 Type II, ISO 27001 and ISO 42001 and runs a trust center at trust.giga.ai, and the CLI uses API keys and rotates credentials. There are no roles, SSO or other controls over who in the customer's organization can change an agent, and the developer docs sit behind a login.

Vapi supports SSO through any SAML 2.0 or OIDC identity provider on the Enterprise and Premier plans, and RBAC with Admin, Editor and Viewer roles assigned per member. SCIM is not supported. Vapi's SafeBase trust center announces a completed SOC 2 Type II examination, with the report under NDA, and a public SOC 3, and lists HIPAA, PCI DSS v4.0.1, GDPR and CCPA. HIPAA mode and zero data retention are organization settings.

Each ticket records the customer's intent, the actions the agent took and how the exchange ended (resolved, transferred or abandoned). Full transcripts with intents and tags are pulled from the CLI, Insights explains patterns across conversations, and every Browser Agent step is visible as it runs.

Call logs hold the transcript, messages, analysis, costs, latency, recordings and downloadable pipeline logs for each call, with chat, session, webhook and API request logs beside them. Monitors evaluate call data against thresholds and open issues. Raw data is kept for 14 to 180 days depending on the package.

There is no region choice and no customer hosted or customer cloud option. Hosting runs on AWS, Microsoft Azure and Google Cloud, which Giga names as its hosting subprocessors.

Each organization belongs to the United States or the European Union region, with its own dashboard, API and SIP hosts, such as api.eu.vapi.ai and sip.eu.vapi.ai in the EU. Every resource stays in its region, and each region is an isolated environment. The service is hosted only, with no self hosted or customer tenant option.

Agents are drafted for each business, by Scout from its policies and knowledge or in Agent Canvas from transcripts, recordings or SOPs. Each customer assembles its own agents this way, and Giga offers no named prebuilt agents or template catalog.

Cloneable example builds cover appointment scheduling, medical triage and scheduling, ecommerce order management, property management routing, lead qualification and multilingual support. Each does a different job, but the customer builds each one step by step instead of adopting a packaged agent. Model Intelligence presets are settings.

Giga names no language or voice model provider and offers customers no choice of model. Its subprocessor list is kept in the trust center.

Each assistant's transcriber, model and voice can be swapped for any supported provider. Customers can use their own provider keys, Azure OpenAI and Bedrock credentials, or their own server acting as the LLM. Transcriber and voice fallback plans switch providers automatically on failure.

The Giga CLI and Python SDK (giga-sdk, MIT licensed on PyPI) run over a REST API authenticated with API keys and cover agents, tickets, tests, KPIs, secrets, the knowledge base and deploys, with JSON output for scripting. Its API reference at docs.giga.ai sits behind a customer login.

The API covers assistants, squads, calls, chats, campaigns, sessions and phone numbers, with server SDKs, a Web SDK and a CLI beside it. The Vapi MCP Server at mcp.vapi.ai, authenticated by bearer token, manages assistants, phone numbers and calls from any MCP client.

Agent Canvas runs simulated test cases, the CLI runs test suites with CI gates before deploy, rollouts start on 1 percent of traffic and scale on KPI results, and Scout tests changes on a slice of live traffic against the KPI the team sets.

The Browser Agent drives a real browser. It launches a secure cloud browser, logs in to browser based and legacy tools without APIs, and clicks, selects and validates inputs through the workflow. With the user's approval it can also take control of the cursor on the business's website, with every action visible.

Browser, desktop and computer control are not described. IVR navigation presses DTMF keys to walk a phone menu on a telephone keypad, not a screen. Web SDK client side tools trigger side effects in the customer's own web app, which is the product running in a browser.
