Vision Agents
Open-source Python framework for building real-time voice and video AI agents with any model.
Choose Vision Agents when your agent has to see as well as listen — per-frame YOLO or Roboflow processing inside a live conversation is the reason this exists, and few open-source options give you that with model choice intact. The cost is ownership: you run the server, metrics, and provider keys. If you just need a fast voice bot and don't want Python infrastructure on your plate, a managed platform gets there sooner.

Skip Vision Agents if you want a no-code builder or a managed platform to run your infrastructure — this framework expects you to deploy the server, hold the provider API keys, and maintain the Python yourself.
Each of the 35+ provider integrations bills on its own account — LLM tokens, STT minutes, TTS characters, and vision inference all land on separate invoices you manage.
Free and open-source with no licensing fees, so the framework itself is cheaper than managed voice-agent platforms like Vapi or Retell that charge per minute. The real cost comparison is total cost of ownership: you add compute for the HTTP server and Kubernetes deployment plus separate bills from each of the 35+ model providers you wire in. For a small Python team already running its own cloud infrastructure, that's often cheaper at volume; for a team without DevOps capacity, managed platforms

What is Vision Agents?
Vision Agents — Open-source Python framework for building real-time voice and video AI agents with any model. Best for Python developers building low-latency voice and video agents with full model choice, Teams that need frame-level computer vision inside a realtime conversation loop, Telehealth, live coaching, and sports commentary products where latency is the product. Free to use.
Vision Agents is an open-source Python framework for teams building low-latency voice and video AI agents without adopting a managed agent platform. You choose the models — any LLM, speech, or vision provider from 35+ integrations including OpenAI, Gemini, Anthropic, Deepgram, ElevenLabs, YOLO, and Roboflow — and ship agents for telehealth, voice support, live coaching, and interactive avatars. The framework gives you two construction paths. Use Realtime APIs over WebRTC/WebSocket when you want streaming handled for you, or wire a custom STT → LLM → TTS pipeline when you need control over each hop. Core classes — Agent, LLM, Realtime, Processors, and Avatar — plus an events reference cover the wiring. Video is the differentiator. You can run YOLO, Roboflow, or your own models on every frame, which is what the shipped examples demonstrate: a golf coach scoring your pose while Gemini coaches live, a security camera doing face and package detection, a sports commentator tracking ball and players, and Decart Lucy-2 virtual try-on. Production scaffolding includes an HTTP server, Prometheus metrics, Docker and Kubernetes deployment guides, Twilio for bi-directional phone calls, TurboPuffer or Gemini FileSearch for RAG, MCP for tool use, and Anam interactive avatars. Latency targets sub-500ms on Stream's edge network, with 333,000 free participant minutes. Against managed platforms like Vapi or Retell, this trades speed-to-launch for model freedom and frame-level perception.

Behind the verdict
Where Vision Agents earns its place is the video loop. Running a detector on every frame while a speech pipeline keeps talking is genuinely fiddly to build yourself, and the shipped examples — golf swing coach, package-detecting security cam, live sports commentator — are useful starting points rather than toy demos. If your product's value depends on the agent reacting to what it sees within the same conversation, this is a strong fit. Pick it when you're a Python team that wants to own the stack. Model choice across 35+ providers matters here: you can swap a TTS vendor, drop in Gemini FileSearch or TurboPuffer for retrieval, and keep Twilio phone calls in the same framework. The two-mode design (realtime APIs versus a hand-built STT → LLM → TTS chain) is the part we'd actually stress-test early, since it determines how much latency and cost tuning you can do later. Pass if nobody on the team wants to run servers, manage API keys, and own deployment. A managed voice-agent platform will get a working bot live faster, and the frame-level vision advantage is wasted on a text-only chatbot. In practice, the sub-500ms target rides on Stream's edge network, so treat that as a dependency to plan around rather than a number you inherit for free. Self-hosting also means you're the one watching Prometheus metrics when a provider has a bad day. Budget real time for provider key management and for tuning your chosen pipeline before you promise customers a latency figure.
Models under the hood
as of 2026-11-14
Limitations
- Open-source and self-hosted: you manage your own infrastructure and API keys.
- Latency targets depend on Stream's edge network; external WebRTC transports may not achieve sub-500ms.
- Requires Python expertise, with no no-code surface, and the documentation lists 35+ integrations but does not provide built-in rate limiting or an SLA.
- Model providers each bill separately, so your cost stack is per-provider rather than a single invoice.

Where the pricing makes sense
The company stage and team size where Vision Agents's pricing actually pencils out — and where peers do it cheaper.
Free and open-source with no licensing fees, so the framework itself is cheaper than managed voice-agent platforms like Vapi or Retell that charge per minute. The real cost comparison is total cost of ownership: you add compute for the HTTP server and Kubernetes deployment plus separate bills from each of the 35+ model providers you wire in.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Vision Agents actually fits — and what changes day-one when you adopt it.
You scaffold a project with the CLI, wire a Twilio number for bi-directional audio, point the LLM at your provider of choice, and add TurboPuffer vector search so the agent answers from your knowledge base instead of improvising.
Outcome: A working inbound call agent within a day, with the transcript and retrieval path under your own control and no per-minute platform fee layered on top of provider costs.
You register a YOLO model as a Processor so it runs on every incoming frame, use face recognition and package detection to trigger events, and ship the agent in a Docker container with Prometheus metrics for alerting.
Outcome: Detection and response happen inside the same realtime loop rather than in a separate batch pipeline, so alerts fire while the event is still happening.
You use the Anam Avatar class alongside a realtime LLM and TTS provider, so the avatar sees the camera feed, hears the user, and responds with synced voice and video.
Outcome: A demo-grade interactive avatar running on your own infrastructure, with the freedom to swap the LLM or TTS provider without rewriting the agent.
Use cases
- Build a real-time AI phone support agent with Twilio and RAG-backed knowledge bases.
- Create an interactive Anam avatar that sees, hears, and responds with voice and video.
- Deploy a smart security camera with YOLO face recognition and package detection alerting.
- Develop a live sports commentator using Roboflow object tracking plus LLM play-by-play.
- Implement a virtual try-on experience using Decart's Lucy-2 model with reference images.
- Wire up a multi-modal coach that watches your golf swing via pose detection and gives live feedback.
Setup time & first value
How long it actually takes to get something useful out of Vision Agents — broken out by persona, not the marketing-page minute.
Python developers: the CLI scaffolds and runs a first agent in under five minutes per the docs, and a Twilio phone agent can be live the same day using the phone setup guide. Teams adding video: budget longer for YOLO or Roboflow model wiring and frame-rate tuning. Production deployment with Docker, Kubernetes, and Prometheus metrics is a separate engineering pass measured in days, not minutes.
Switching to or from Vision Agents
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From Vapi or Retell: rebuild the conversation loop on the Agent and Realtime classes, then move prompt logic and tool definitions into your own Python instead of the managed dashboard.
- →From a raw WebRTC build: keep your transport, add the Processors class so YOLO or Roboflow runs per frame, and let the framework handle STT → LLM → TTS orchestration.
- →From a text-only chatbot stack: add a realtime class or an STT/TTS pair and reuse your existing RAG index via TurboPuffer or Gemini FileSearch.
- ↗To Vapi or Retell: port conversation logic into the managed dashboard and drop your own server, metrics, and deployment tooling.
- ↗To a single-vendor realtime API: replace the multi-provider setup with one vendor's model and transport, accepting less model choice for fewer API keys to manage.
