three.ws 3D Studio (free)

three.ws 3D Studio turns a text prompt or an image into an interactive, downloadable 3D model (GLB) — free. forge_free(prompt) generates a model from text; text_to_avatar and mesh_forge generate an avatar or art-directed mesh from text or a reference image; rig_mesh(glb_url) makes a static model animation-ready; forge_avatar does generate + rig in one step. Each result includes a glbUrl and a viewerUrl and renders inline in a 3D viewer widget. refine_model(glb_url, instruction) iterates on a generated model in plain language ("make it metallic") and keeps a version lineage you can branch or revert. If a result comes back with status "pending", the model is still rendering: call check_job(job_id) after the suggested wait to collect it. To give the assistant a LIVING body: create_agent_persona(glb_url, name) saves a rigged model as a named, persistent persona and returns a persona_id; persona_say(persona_id, text) makes that body lip-sync the reply and emote; get_agent_persona(persona_
