Primate Vision watches video live and returns deterministic verdicts with evidence. These are genuinely different products — here's the honest head-to-head, with receipts." canonical: https://primateintelligence.ai/blog/primate-vision-vs-twelve-labs --- People compare us to Twelve Labs constantly, and the comparison is mostly a category error. Twelve Labs is the best-funded pure-play in video understanding — a $100M Series B closed July 2026 — and the category leader in **semantic search over stored video archives**. Primate Vision is the only managed API that watches video **live, at native frame rates**, and returns a **deterministic verdict** — yes / no / indeterminate — with a calibrated confidence score and evidence you can watch. Different products, answering different questions. If your videos are already recorded and your problem is *finding moments*, choose Twelve Labs. If your problem is *knowing whether something is happening* — on a camera, right now, with an answer you can act on — Twelve Labs cannot do it at all. Primate Vision was built for exactly that. *This is part of our [full 2026 video-AI landscape comparison](/blog/primate-vision-vs-video-ai-landscape-2026).* --- ## Two different questions Every product in this category is secretly an answer to one question. Twelve Labs answers: *"Where in my 10,000-hour archive does X appear?"* You upload videos into indexes (Marengo 3.0 embeddings), then search, summarize, or extract structured metadata (Pegasus 1.5) across the corpus — in natural language, across 36 languages, spanning visuals, speech, on-screen text, and audio. That's a real category, and they lead it. ([TwelveLabs docs](https://docs.twelvelabs.io/v1.3/docs/get-started/introduction)) Primate Vision answers: *"Is X happening — and can you prove it?"* Point it at a live stream (managed WebRTC) or a file (upload or URL ingest, up to 2 GiB), ask in plain English, and get a deterministic verdict (`yes` / `no` / `indeterminate`), a 0–1 confidence score, timestamped evidence segments, and an annotated overlay evidence video — at 45ms p50 per-frame inference, published on a public [/performance](https://www.primateintelligence.ai/performance) page. ## The head-to-head | Capability | Primate Vision | Twelve Labs | |---|---|---| | Live stream input | ✅ managed WebRTC, native frame rate | ❌ none — no WebRTC/RTSP/gRPC/WebSocket anywhere in docs ([upload methods](https://docs.twelvelabs.io/v1.3/docs/concepts/upload-methods.md)) | | Published latency | ✅ 45ms p50 / 316ms p95, 11.8 fps sustained | ❌ no latency numbers published anywhere | | Verdict contract | ✅ deterministic yes/no/indeterminate + calibrated 0–1 confidence | ⚠️ generative text or JSON-schema output — temperature-tunable, no calibration, no reproducibility guarantee | | Timestamped segments | ✅ | ✅ start/end per segment; strong | | Evidence artifacts | ✅ annotated overlay evidence video | ⚠️ thumbnails only; no rendered clips or overlays | | Semantic search / embeddings | ❌ none | ✅ flagship — 512-dim Marengo embeddings, vector-DB ecosystem | | Transcript / OCR / audio | ❌ visual only | ✅ core strength: speech search, OCR, logos, music | | Multi-video batch | ❌ (batch = up to 10 prompts on one video, 50% off after the first) | ✅ up to 1,000 videos per Analyze call | | Webhooks | ✅ Standard Webhooks signing, retries, redelivery + `Prefer: wait` | ✅ indexing notifications, dashboard-managed | | Agent accessibility | ✅ llms.txt, markdown docs twins, MCP server, sandbox key in one POST | ✅ best-in-class: llms.txt, .md docs, docs MCP server, Claude Code plugin | ## The real-time gap is total, not partial There is no live ingestion of any kind in Twelve Labs' documentation. No WebRTC, no RTSP, no streaming input path. Their "real-time" story is two things: token-by-token *text delivery* on sync Analyze (the video must be fully uploaded first), and a partner integration where VideoDB does the streaming and Pegasus does the analysis afterward. That's not real-time video analysis. That's fast typing. And even for stored video, there's index-first friction: since July 2026 every upload is async — you poll each asset to `ready` before you can ask anything. Ask-one-question-of-one-clip is a multi-step pipeline. On Primate Vision it's one API call with `Prefer: wait`, or a webhook when it's done. ## Verdicts: deterministic vs. generative When a Twelve Labs answer matters — "did the forklift enter the loading zone?" — you get generated text, or generated JSON shaped by a schema you define. The JSON-schema path (GA on Pegasus) genuinely gets close to a verdict shape. But it's still a generative approximation: temperature-tunable, uncalibrated, with no reproducibility guarantee in their docs. It's not that their model is worse — it's that a language model is the wrong instrument for a measurement. Primate Vision's verdict is a different kind of object: a **deterministic answer** from a closed vocabulary — `yes` / `no` / `indeterminate` — never free-form generation, with a calibrated 0–1 confidence score, model version pinning (`darwin-1.3`), and a fully deterministic test mode for CI. And every yes ships with proof: timestamped clips plus an annotated overlay evidence video a human can watch and forward. ## Pricing: two very different meters **Twelve Labs stacks meters.** One-time indexing at $0.042/min, **plus a perpetual infrastructure fee of $0.0015 per indexed minute per month** — a 10,000-hour archive costs $900/month just to stay searchable, before a single query — plus $4 per 1,000 searches, plus Pegasus analysis at $0.0292/min input and $0.0075/1k output tokens. And Segment multiplies: their own FAQ example shows a 60-minute video with 4 segment definitions billing **240 minutes**. ([Twelve Labs pricing](https://www.twelvelabs.io/pricing)) **Primate Vision has two lanes**, stated plainly: 1. **Metered — $0.01 per second of source video** ($0.60/min), flat and fps-independent. Queued time free; failed jobs free. A 30-second clip → verdict + confidence + timestamps + evidence video = $0.30. 2. **[Enterprise — contact us](https://primateintelligence.ai/pricing#enterprise)** for 24/7 continuous monitoring and camera fleets: dedicated capacity or on-site deployment at a small fraction of the metered rate, under highly discounted enterprise plans. The honest normalization: on recorded footage, Twelve Labs works out to roughly $1.75–$2.52 per camera-hour (estimate, batch-upload workaround — they have no live path at any price), versus $36/camera-hour† at Primate's metered rate. That's ~14–20× cheaper per raw hour of archive. If archive search is your workload, that gap is real and you should weigh it. But the meters buy different things: theirs buys searchability; ours buys answered questions with evidence, live or on demand. You don't buy camera-hours on our metered lane. You buy verdicts. † *Metered rate normalized for comparison. Primate does not sell 24/7 continuous monitoring at the metered rate — continuous and fleet workloads use enterprise plans; [contact us](https://primateintelligence.ai/pricing#enterprise).* ## Choose Twelve Labs instead when… We'd rather you pick the right tool than the wrong one of ours: - **You have a large stored archive and need to find moments in it.** Media libraries, sports footage, ad inventory, recorded bodycam/CCTV. Primate Vision has no search, no embeddings, no corpus features — this is Twelve Labs' home turf and they're the leader. - **You need speech, on-screen text, or audio understanding.** Interviews, broadcasts, lyrics, logos. Primate Vision is visual-only: no transcription, no OCR, no audio path. - **You're building a RAG/vector pipeline over video.** Marengo embeddings plus a dozen vector-DB partner integrations vs. nothing on our side. - **You need bulk structured extraction over recorded content** — chapters, scene metadata, custom JSON schemas — at low per-minute cost, up to 1,000 videos per batch call. Primate Vision doesn't batch across videos at all. ## Choose Primate Vision when… - **The camera is live.** Twelve Labs cannot ingest a stream at any price. Primate Vision is managed WebRTC at native frame rates, with mid-stream prompt changes over one WebSocket message. - **You need an answer, not a reading list.** A deterministic yes/no/indeterminate with calibrated confidence beats generated prose when the output feeds an alert, a workflow, or a compliance record. - **You need proof.** An annotated overlay evidence video plus timestamped clips — versus thumbnails. - **You need to know what it costs before you run it.** One flat meter (and a `validate_only` dry-run that estimates cost without touching GPU or credits) versus five stacking meters and a segment multiplier. - **Latency is a requirement, not a hope.** We publish 45ms p50 / 316ms p95 / 11.8 fps / 6.6s session setup. They publish nothing. ## Try it **[Try it for free](https://primateintelligence.ai/signup)** — real processing, no card required to start. **Your AI agent can do it for you — right from Claude.** Primate Vision ships an MCP server, llms.txt, markdown docs twins, and a sandbox key available in a single POST — your agent can get a key, upload a clip, and read back a verdict without a human touching a dashboard.
