Foundation models

Robot foundation models

Named vision-language-action and world-action policies, with versioned parameters, licences and public artefacts—not a leaderboard, the 3D catalogue or the SDK / simulator inventory.

Class definition

A policy is not a robot body; hardware numbers stay on class pages.

Demos, parameters and gaps

Company demonstrations are not benchmarks. Blog parameter counts remain press unless a paper or model card confirms them. Missing artefacts stay —; unpublished licences and backbone-licence conflicts remain explicit.

Identity. Genesis AI supports, but is not, the Apache-licensed Genesis-Embodied-AI/genesis-world engine.
GENE-26.5 and GR00T N1 identity

GENE-26.5 is not Galbot GraspVLA, LDA-1B or GroceryVLA. GR00T N1’s paper names Fourier GR-1 and thanks 1X; it does not name Galbot bodies or Genesis Eno.

Genesis AI — the lab

Stealth exit

Genesis AI emerged from stealth on 2025-07-01 with a $105M seed co-led by Eclipse and Khosla Ventures. Participating names in contemporaneous coverage include Bpifrance, HSG, Eric Schmidt, and Xavier Niel.

CEO Zhou Xian (CMU robotics Ph.D., 2024); co-founder Théophile Gervet (ex-Mistral; press also names Skild AI). Stated goal: a universal robotics foundation model plus a horizontal platform. [P1]

GENE-26.5

Announced 2026-05-06 as the company’s VLA / “robot brain.” Company materials describe a human-scale five-finger hand and a tactile e-skin data-collection glove.

Claimed for the glove (company / internal testing):

  • a 1:1:1 glove→human-hand→robot-hand mapping;
  • “100× cheaper” than typical teleop rigs;
  • up to 5× data-collection efficiency.

The company blog assigns Genesis Hand 1.0 “20 active, back-drivable degrees of freedom.” That figure is a hand claim, not a robot-body DoF, and is not copied into any hardware table. [P2] [P3]

GENE-26.5 gaps. Parameters, success rates, benchmarks, API, model card and released weights were unpublished when checked.
Demos and the Eno body

Demos: 20-step meal prep with one-handed egg cracking, pipetting, wire harnessing, Rubik’s cube, piano and four-object one-handed grasp. The later Eno body remains announced, without a numeric column.

Policy models — what is actually public

Helix architecture figures are company claims, not paper results.

Skild S1 and GR00T versions

Skild S1’s in-context-learner post publishes neither parameters nor weights. GR00T here means the N1-2B paper checkpoint; N1.6 and N1.7 remain separate versions.

OpenVLA inherits Llama 2’s Community License despite its card’s MIT label.

Helix 02, π0.5 and suites

Helix 02 remains a later release. π0.5’s parameter split comes from its paper, not π0’s blog. Suite identities live in the Benchmarks atlas; policy rates stay here.

Smaller open VLAs and papers without public weights

SmolVLA and SpatialVLA are later checkpoints or papers. OpenVLA-OFT fine-tunes OpenVLA 7B; it is not a new pretrain. Gemini Robotics publishes a paper and company blog, but no parameter count or public weights.

Gemini Robotics has no model card. SpatialVLA’s project page establishes identity; no weight dump is copied here. OFT suite checkpoints remain fine-tunes, separate from OpenVLA 7B. See the documented LIBERO-Spatial pair.

FAST tokenizer

FAST is a DCT + BPE action tokenizer, not a standalone VLA; do not invent policy parameters. Physical Intelligence’s /blog/fast returned HTTP 404 when checked; the research page is cited instead.

Open X-Embodiment (arXiv:2310.08864) is a dataset, not a policy.

RT-2, π0 and RDT-1B

RT-2 released no weights with its paper. π0’s blog does not establish π0.5’s parameter split. RDT-1B is Tsinghua TSAIL research, not Galbot or Genesis. Current openpi checkpoint names remain separate.

Parameter count and π0.5 weights

Do not transfer N1’s 2.2B count to N1.6/N1.7. π0.5 base weights remain gs://openpi-assets/checkpoints/pi05_base in the family column.

Documented evaluation pair — not a ranking

The pinned recipe defines the model, suite and checkpoint protocol. It does not reproduce the paper’s four-suite averages. Unknown fields are not zero; openpi’s π0.5 LIBERO results use a different protocol.

Bounded native evidence. A site-run OpenVLA-OFT trial succeeded 1/1 on Spatial task 0, policy seed 7 / environment seed 0. This is not the 500-episode protocol or a suite score.
Result provenance

Paper-reported, upstream-reproduced and site-run results stay distinct; other models’ rates are not comparable here.

Galbot / EPIC models and version records

Galbot / EPIC models stay on the research cards above unless a compatible public artefact is published. Machine-readable version records live in worlds/models.json; this page does not fetch that file.
