Verdict: The Tesla Optimus V2.5 ($90,000 projected) outmuscles the Fourier GR-3 ($80,000 pre‑order) on payload and battery life, but the GR‑3’s dominant 55 degrees of freedom and tangible pre‑order availability make it the smarter choice for dexterity‑intensive tasks and anyone who needs a humanoid robot now. If you require raw strength and are already deep inside the Tesla AI stack, Optimus has potential — once it ships.
The core tension is clear: Tesla’s prototype muscle versus Fourier’s production‑ready dexterity. This article breaks down every spec, the real‑world availability gap, and which use cases each machine fits, so you can decide whether to wait for the Tesla Optimus V2.5 or secure a Fourier GR‑3 today. Both robots are profiled in full on the Tesla Optimus V2.5 and Fourier GR‑3 database pages.
Quick Verdict: Who Wins?
- Best overall value: Fourier GR‑3 — $80,000 pre‑order, 55 DOF, and shipping in 2025‑2026.
- Best for fine manipulation: Fourier GR‑3 — 55 DOF gives near‑human dexterity.
- Best for heavy payload tasks: Tesla Optimus V2.5 — 20 kg arm payload vs. 15 kg.
- Best battery endurance: Tesla Optimus V2.5 — 4 hours vs. 3 hours.
- Best if you need a robot today: Fourier GR‑3 — pre‑orderable, while Optimus remains a prototype.

Tesla Optimus V2.5: The AI‑Heavy Prototype
Announced by Tesla in 2025, the Optimus V2.5 is the latest iteration of the company’s humanoid platform, engineered in Austin, Texas. Standing 173 cm tall and weighing only 57 kg, it can carry a 20 kg payload per arm at a walking speed of 7.2 km/h. Its battery runs for up to 4 hours, and it packs 28 degrees of freedom. While Tesla lists a $90,000 projected price, the robot is not openly for sale; it remains in prototype development, with Tesla inviting collaboration but no public purchase channel. The on‑board computer is a custom Tesla‑designed AI chip, presumably leveraging the FSD (Full Self‑Driving) architecture, but detailed specs remain under NDA.
Fourier GR‑3: The Dexterity Champion on Pre‑Order
The Fourier GR‑3, built by Fourier Intelligence in Shanghai, China, is a 168 cm, 60 kg general‑purpose humanoid with a staggering 55 degrees of freedom — over twice as many as the Optimus V2.5. It lifts 15 kg, walks at 6.5 km/h, and operates for 3 hours on a charge. Unlike Optimus, the GR‑3 can actually be ordered: Fourier has set a pre‑order price of $80,000 and aims to begin shipping units in 2025‑2026. Its sensor suite typically includes cameras, LiDAR, and an IMU, and the company is actively building a Fourier SDK with ROS2 compatibility on the roadmap. This makes the GR‑3 one of the most promising commercially available humanoids for research and early‑stage industrial pilots.
Price & Total Cost of Ownership
Tesla has projected the Optimus V2.5 at $90,000, but no orders are being taken; the price is aspirational and could change. The Fourier GR‑3 is an $80,000 pre‑order, with a clear path to delivery. Neither company publicly breaks down software subscription or maintenance costs, so a genuine 3‑year TCO is impossible to calculate today. However, the GR‑3’s pre‑order model suggests earlier access to spare parts and support, whereas Optimus’s prototype status means any service network is purely hypothetical.
Winner: Fourier GR‑3 — it’s actually buyable and $10,000 cheaper.
Performance & Specs: Head‑to‑Head
Payload
Optimus V2.5 lifts 20 kg per arm; GR‑3 manages 15 kg. That 33% advantage matters in industrial material handling, where every kilogram counts.
Winner: Tesla Optimus V2.5
Speed
Optimus walks at 7.2 km/h vs. GR‑3’s 6.5 km/h — a minor edge, unlikely to decide a purchase except in strictly timed logistics.
Winner: Tesla Optimus V2.5 (marginal)
Battery Life
A 4‑hour runtime on Optimus outlasts the GR‑3’s 3‑hour battery. In continuous‑shift scenarios, that extra hour reduces recharge downtime.
Winner: Tesla Optimus V2.5
Degrees of Freedom (Dexterity)
This is the headline differentiator: 28 DOF on Optimus vs. 55 on Fourier GR‑3. The GR‑3’s articulated hands and full‑body mobility enable intricate tasks — bin picking, fine assembly, tool manipulation — that a 28‑DOF robot simply cannot perform as fluidly. In human‑like dexterity, the GR‑3 is a generation ahead.
Winner: Fourier GR‑3
Software & SDK Ecosystem
Tesla has not yet released an SDK or ROS2 driver for Optimus. The robot will almost certainly run a proprietary stack tightly coupled with Tesla’s AI and simulation tools, promising powerful deep‑learning capabilities but requiring developers to work within Tesla’s walled garden. Fourier, on the other hand, is developing a public Fourier SDK and has stated plans for ROS2 integration, which will make the GR‑3 far more accessible to the global robotics research community.
Winner: Fourier GR‑3 (openness and timeline)
Autonomy & Sensors
Optimus V2.5 relies on Tesla’s vision‑based autonomy — a strategy that has proven remarkably capable in its electric vehicles. While sensor details are scant, the robot is expected to use multiple cameras and the in‑house AI chip. Fourier GR‑3 ships with a richer sensor array out of the box: cameras, LiDAR, and an IMU give it depth perception and 3D mapping from day one. For navigation in unstructured environments, the GR‑3’s multi‑modal sensing is more robust.
Winner: Fourier GR‑3 (more complete sensor stack)
Build Quality & Durability
Optimus V2.5 is lighter (57 kg vs. 60 kg) and built for a 20 kg payload, hinting at a sturdy drive train. However, as a prototype, no public durability data exists. Fourier GR‑3 is designed for general‑purpose commercial use from the start and is expected to ship with industrial‑grade joint motors rated for continuous duty. No IP rating has been published for either robot, so any conclusion is tentative.
Winner: Draw — both are unproven outside the factory floor.
Which Should You Buy? Tesla Optimus V2.5 vs Fourier GR‑3 by Use Case
Choose the Tesla Optimus V2.5 if… - You need maximum arm payload (20 kg) for material transport. - Your environment is tightly integrated with Tesla’s AI and data ecosystem. - You can wait 1‑2 years for commercial availability. - Battery endurance (4 hours) is a priority.
Choose the Fourier GR‑3 if… - Dexterity is non‑negotiable — 55 DOF unlocks complex manipulation. - You want a robot you can pre‑order today and receive within months. - You need a rich sensor suite (LiDAR + cameras) out of the box. - You value an evolving, developer‑friendly SDK and ROS2 roadmap.
Choose neither if… - You require a robot with a proven deployment record (both are too new). - Your budget is below $50,000 — keep an eye on lower‑cost humanoids like the Unitree G1.
Real‑World Deployments & Track Record
Tesla Optimus V2.5: No public deployment data. The robot remains in Tesla’s R&D labs; there are no named commercial sites, operating hours, or units shipped.
Fourier GR‑3: As of mid‑2026, Fourier has not disclosed specific pilot customers or shipped units. However, the pre‑order program signals imminent production, and the company has a track record with its GR‑1 and GR‑2 series, which have been tested in university and research settings.
Note: All deployment claims here are limited by manufacturer silence; any advertised numbers would be speculative.
SDK, Software & Developer Ecosystem
Tesla’s approach is famously vertically integrated. The Optimus V2.5 will almost certainly run a proprietary software stack with tight AI/hardware co‑optimization, but open SDKs and ROS2 support are not guaranteed. Fourier is taking the opposite path: a dedicated Fourier SDK is in the works, and the company has publicly committed to ROS2. For researchers and integrators who want to hack, simulate, and adapt, the GR‑3’s software openness is a massive advantage.
Winner: Fourier GR‑3
Support, Warranty & Availability
Tesla does not offer a public warranty or support plan for Optimus because it is not sold. Enterprise partners may negotiate custom arrangements. Fourier is building a commercial sales channel, so pre‑order customers can expect a standard warranty and service package, though specifics have not been published. Shipping lead times for the GR‑3 are estimated 3‑6 months after order, while Optimus has no timeline at all.
Winner: Fourier GR‑3
