FAL.ai model catalog access — image, video, audio, 3D, LoRA training, and more via fal-ai/ and bytedance/ and wan/ endpoints. Activate when the user configures any nebula node that routes through FAL (kling, sora, veo, flux, seedance, wan, luma, pixverse, ltx, moonvalley, hunyuan3d, recraft, nano-banana via FAL, and 30+ others), when the user mentions a fal-ai/ slug, or when they ask which FAL model to use for a task. Entry point for 160 curated per-model skills + category overviews at `.agents/skills/fal/`.
FAL (fal.ai) is Nebula's all-purpose generation gateway — one API key fronts 52 ready-to-use nodes for image, video, 3D, and audio generation (FLUX, GPT Image 1.5/2, Seedream, Ideogram 4 (gen + edit/remix/reframe/replace-background/character/upscale), Recraft, Sora 2, Kling, Wan, Luma Ray 2, PixVerse, LTX, Seedance, Hunyuan3D, Meshy, Stable Audio 2.5, ACE-Step, MMAudio V2, Demucs, Clarity Upscaler, SeedVR2 Video Upscale) plus the catch-all `fal-universal` slug node. Activate when the user configures any FAL node — flux-1-1-ultra, flux-2-pro, flux-schnell, fast-sdxl, flux-kontext, flux-fill-inpaint, gpt-image-1-5, gpt-image-1-5-edit, gpt-image-2-fal-generate, gpt-image-2-fal-edit, seedream-4-5, ideogram-v4, ideogram-edit, ideogram-remix, ideogram-reframe, ideogram-replace-background, ideogram-character, ideogram-upscale, recraft-v4-raster, recraft-v4-svg, sora-2, kling-v2-1, kling-v3, kling-o3, wan-2-6-t2v, wan-2-6-i2v, wan-2-6-r2v, luma-ray2-t2v, luma-ray2-i2v, luma-ray2-flash-modify, pixverse-v4-5, ltx-video
Anthropic (Claude) Messages API in Nebula — a single text-gen node (Claude / claude-chat) that turns a text prompt plus optional image(s) into streamed text, with system prompt, temperature/top_p/stop sampling, and extended-thinking. Use for captioning, summarizing, translating, rewriting, reasoning, and drafting prompts to feed other media nodes. Activate when the user configures the `claude-chat` node, wires a Claude/Anthropic node into a graph, or asks about Anthropic/Claude in Nebula. Sourced from the official Anthropic Messages API (platform.claude.com/docs/en/api/messages) and the Nebula audit guide docs/api-guides/anthropic.md on 2026-06-04.
ElevenLabs audio API in Nebula — text-to-speech, sound-effects-from-text, speech-to-speech voice changing, audio isolation (denoise), translated dubbing, and speech-to-text transcription, all as audio-gen nodes. Activate when the user configures any elevenlabs-tts, elevenlabs-sfx, elevenlabs-sts, elevenlabs-isolation, elevenlabs-dubbing, or elevenlabs-stt node, or asks about ElevenLabs in Nebula. Sourced from the official ElevenLabs API reference (elevenlabs.io/docs/api-reference) cross-checked against backend/handlers/elevenlabs.py + backend/data/node_definitions.json, and the Nebula audit guide docs/api-guides/elevenlabs.md, on 2026-06-05.
Best practices for prompting Google's Gemini-family APIs — Gemini text models, Imagen, Nano Banana (Gemini 3.1 Flash Image), and Veo video. Activate when writing prompts, building graphs, or configuring nodes that target any Gemini model, when editing files importing `google-genai` / `@google/genai`, or when the user asks about Imagen, Nano Banana, or Veo. Routes to topic files for deep guidance. Sourced from ai.google.dev with fetch dates noted — verify against the live docs for anything that smells stale.
Higgsfield video generation in Nebula — text-to-video and image-to-video short cinematic clips via the DoP ("Depth of Presence") model plus Kling v2.1 Pro and Seedance v1 Pro guest models, with duration and aspect-ratio control. Activate when the user configures the `higgsfield` node or asks about Higgsfield in Nebula. The node is video-output only (no Soul images, Speak lipsync, or motion-camera presets are wired). Sourced 2026-06-04 from the official Higgsfield API docs (docs.higgsfield.ai) plus the Nebula audit guide docs/api-guides/higgsfield.md.
Ideogram image nodes in Nebula — v4 generate, masked inpaint (ideogram-edit), maskless edit-prompt, remix, reframe, replace-background, character, upscale, transparent, remove-background, describe, magic-prompt. Activate when the user configures any ideogram-* node, asks about Ideogram in Nebula, or wants to wire or test mask-painter → ideogram-edit inpainting on the canvas. Covers dual-route auth (IDEOGRAM_API_KEY direct vs FAL_KEY fallback), mask polarity (BLACK = edit), the four-wire canvas graph, Inspector mask painting, expand_prompt, preset image execution, auto-wire of base image, and how to verify a visible inpaint result. Sourced from docs/api-guides/ideogram.md and live canvas E2E on feat/inpainting (2026-06-10).
MiniMax (Hailuo) video generation in Nebula — text-to-video, image-to-video (first frame), and subject-reference (face-consistent) video via Hailuo 2.3 / Hailuo 2.3 Fast / Hailuo 02 / S2V-01 on the async /v1/video_generation endpoint. VIDEO ONLY in Nebula (the API also offers TTS, voice clone, music, and image gen, but no Nebula node wires those). Activate when the user configures any minimax-t2v, minimax-i2v, or minimax-s2v node, or asks about MiniMax / Hailuo in Nebula. Sourced from the official MiniMax platform docs (platform.minimax.io) and the Nebula audit guide docs/api-guides/minimax.md, cross-checked against backend/handlers/minimax.py and node_definitions.json on 2026-06-04 (model enums updated 2026-06-10).
