Olympus
Olympus turns a Multimodal LLM into a task router that dispatches 20+ computer vision tasks to specialist models.
If you are researching multi-model routing or want a benchmarked, no-cost starting point for a multi-model vision pipeline, Olympus is an easy download — CVPR 2025 Highlight, published code, dataset and a benchmark with reported numbers you can try to beat. If you need a managed vision service with an SLA, this is the wrong shelf; Olympus is a framework you run yourself, and the project page describes no hosting or API.

Skip Olympus if you need a managed vision API with an SLA and someone else operating the models — this is a research framework you run and maintain yourself, and its published results are benchmark numbers, not a service guarantee.
Routing through a controller MLLM plus specialist modules means GPU compute for every request, and that bill scales with the number of chained actions rather than with a flat fee.
Olympus is released as open-source code, dataset and benchmark with the paper, so the relevant comparison is not vendor tiers but research frameworks and managed vision APIs. Against paid managed services such as Google Cloud Vision or AWS Rekognition, Olympus costs no licence fee but you supply the compute and the engineering.

About Olympus
Olympus is an open-source research framework from University of Oxford and Microsoft, presented as a CVPR 2025 Highlight, that reframes a Multimodal Large Language Model as a controller for computer vision work. Instead of scaling one giant generative model, it uses instruction-based routing: your prompt goes to the controller MLLM, which emits task-specific routing tokens plus a refined prompt, then schedules a dedicated specialist module for the job. The split of labor is the interesting part. Multimodal understanding — visual question answering, for instance — is answered directly from the MLLM's inherited capacity, while generative and classic vision work like image generation, image editing and depth estimation is handed to expert modules. The published framework covers more than 20 tasks spanning images, videos and 3D content, and it supports chained actions, so a single prompt can trigger a sequence such as VQA to image editing to style transfer. Evidence comes from OlympusBench, the benchmark released alongside the work: an average routing accuracy of 94.75% across 20 tasks and 91.82% precision in chained-action scenarios, plus multimodal evaluation across 11 distinct benchmarks and a human evaluation section. Olympus integrates with existing MLLMs without architectural changes, and the authors published the paper, arXiv preprint (arXiv:2412.09612), video, dataset and code. Who it suits: computer vision researchers and developers who want a reproducible testbed for stacking specialist vision models behind one instruction interface. It is not a turnkey product — the project page describes a framework, code and a benchmark, not a hosted runtime — so expect to run code and provision models yourself. Compared with a managed vision API, the tradeoff is control and zero license cost in exchange for doing the engineering.
Behind the Verdict
We'd reach for Olympus when the research question is routing itself. The framework's premise — keep the MLLM as the controller, farm the actual pixels out to specialists — is a practical answer to the cost of training heavy generative models, and the reported 94.75% average routing accuracy across 20 tasks gives you a number to attack rather than a vague claim. The chained-action support is what makes it more than a routing demo. One prompt can walk from VQA into image editing into style transfer, and the 91.82% chained-action precision is the figure to scrutinize first, because chains are where routers usually fall apart. If your pipeline is a single task, a plain specialist model will be simpler. Pick Olympus if you are an academic or applied researcher with GPUs, a reason to compare routing strategies, and tolerance for wiring modules together yourself. The code and dataset are released, and the arXiv preprint is public, so replication is on you in the ordinary open-source sense. Pass if you need a hosted endpoint, an uptime commitment, or something a non-engineer can operate. The project page documents a framework, a benchmark and a paper — not a service. Nothing here promises a managed runtime, and there is no usage documentation to onboard against. Closest alternatives depend on the job. For a managed general vision API, the cloud vendors are the obvious comparison and they win on operations. For research on tool-using MLLMs, Olympus differentiates by breadth: over 20 tasks across images, video and 3D, evaluated across 11 benchmarks. Where it bites: this is research code from a paper release, so expect to provision specialist models, manage their dependencies, and accept that coverage stops at the documented vision tasks.

Real-world workflow fit
Concrete scenarios for the personas Olympus actually fits — and what changes day-one when you adopt it.
You clone the released code and dataset, point the controller MLLM at your own set of specialist models, and evaluate routing on OlympusBench.
Outcome: You get routing accuracy numbers comparable to the paper's reported 94.75% across 20 tasks and can iterate on the controller without training any heavy generative model.
You wire a single prompt interface in front of specialists for image editing, depth estimation and VQA, and test a chained flow of edit to caption.
Outcome: One instruction drives a multi-step vision workflow instead of you hand-coding each model call.
You use the released dataset and OlympusBench to compare your own router against Olympus under both single-task and chain-of-action settings.
Outcome: You have a published baseline — 91.82% chained-action precision — to report against rather than an untested setup.
Use Cases
- Route a prompt like 'Generate a 3D model of this chair' to the right specialist module.
- Chain image editing into captioning: edit an image, then describe the result.
- Classify objects in a video frame and follow up with VQA about them.
- Run depth estimation on an image and then generate a 3D point cloud.
- Apply style transfer to a video while keeping object detection annotations intact.
- Use the controller MLLM to break a complex multimodal query into routed sub-tasks.
- Benchmark routing accuracy on your own task set using OlympusBench.
Models Under the Hood
as of 2026-10-18
Limitations
- Olympus is a research framework presented at CVPR 2025 (Highlight) from University of Oxford and Microsoft, not a production service; the project page publishes the paper, arXiv preprint, video, dataset and code rather than deployment or usage documentation.
- It relies on a trainable controller MLLM that routes prompts to specialist modules across images, videos and 3D content, which can demand significant computational resources.
- Reported results — 94.75% average routing accuracy across 20 tasks and 91.82% precision in chained-action scenarios on OlympusBench — are self-reported from the paper and are not independently verified here.
- Olympus stays within its 20+ vision domains; tasks outside them, such as NLP or audio, are not covered.

Where the pricing makes sense
The company stage and team size where Olympus's pricing actually pencils out — and where peers do it cheaper.
Olympus is released as open-source code, dataset and benchmark with the paper, so the relevant comparison is not vendor tiers but research frameworks and managed vision APIs. Against paid managed services such as Google Cloud Vision or AWS Rekognition, Olympus costs no licence fee but you supply the compute and the engineering.
Setup time & first value
How long it actually takes to get something useful out of Olympus — broken out by persona, not the marketing-page minute.
There is no signup and no hosted environment: you start from the released code, dataset and arXiv paper. Expect researchers to reach a reproducing routing result in hours to days depending on GPU access, while a developer wiring their own specialists into a working pipeline should budget days to weeks, since setup is code-level rather than configured.
Switching to or from Olympus

- ↗To a managed vision API such as Google Cloud Vision or AWS Rekognition: rewrite your pipeline against the provider's endpoints when you need an SLA.
