AI Generation overview — what you can create

Wevion's Creative Hub supports 5 generation types powered by 12 verified providers. All generation is async: POST returns 202 Accepted with a job_id; client polls GET /api/v1/creative-hub/jobs/:jobId until status = completed. Output stored in your Drive folder + recorded to creative_job table with cost_cents for credit accounting.

Who is this for

Anyone considering AI generation. Reference page for what's possible and which provider to pick.

The async job pattern

All generation endpoints behave identically at the lifecycle level:

  1. Submit: POST /api/v1/creative-hub/generate/{type} with params → returns 202 Accepted + {job_id, status: "pending"}

  2. Process: SQS worker picks up; status flips pending → processing

  3. Complete: worker writes result_urls, cost_cents, marks status: completed

  4. Or fail: on error, status: failed + error_message populated

  5. Poll: client polls GET /api/v1/creative-hub/jobs/:jobId every 5-10 sec

  6. Download: once completed, client fetches result_urls

Generation time varies:

  • Images: 10-60 sec

  • Short videos (5-10s clips): 1-5 min

  • Avatar videos: 2-10 min (longer scripts = longer)

  • TTS: 5-30 sec

  • Compositing: 30 sec - 5 min depending on complexity

creative_job table

Each generation creates a creative_job row with:

  • id (UUID), user_id, team_id

  • type (image / video / avatar / tts / composite)

  • status (pending / processing / completed / failed)

  • provider (one of the 12 verified)

  • prompt (text input)

  • settings (JSON — provider-specific params)

  • result_urls (JSON array of output file URLs)

  • cost_cents (Int — charged amount)

  • drive_folder_id (where output stored)

  • metadata (JSON), error_message (on failure)

  • created_at, completed_at

Used by /jobs/:id for status + by Jobs panel UI.

Cost accounting

Each generation deducts from team credit balance:

  • Cost varies by provider + type + duration + resolution

  • Recorded in cost_cents (integer cents)

  • Ledger entry in credit_transaction (debit)

  • Failed jobs do not charge (cost_cents = 0)

View balance + transactions at /settings/team/billing. See ch-112 AI credits.

Choosing a provider

For images

  • Product photography: flux_2_pro

  • Posters with text: gpt_image_1_5

  • Artistic / stylized: seedream_4_5

For videos

  • Cinematic ads: luma_ray3

  • Text-to-video first try: runway_gen4

  • Physics-heavy scenes: kling_2_6 / kling_3_0

  • Highest quality (Google): veo_3_1

For avatars

  • Only heygen — no choice. Pick avatar + voice in HeyGen library first.

For TTS

  • Premium / cloned voice: elevenlabs

  • Baseline / multilingual default: openai_tts

Best practices

Generate variants

AI is cheap relative to manual. Generate 3-5 per concept, pick winners.

Match aspect ratio to placement

  • 9:16 for Reels / Stories / TikTok

  • 1:1 for feed

  • 16:9 for in-stream

Pair generations

  • TTS narration + video (compositing in ch-117)

  • AI image background + uploaded logo (compositing)

  • Multiple language variants of same avatar (different voice_id per locale)

Watch your credit balance

Generations add up. Set alerts at /settings/team/billing for low-balance warnings.

Common mistakes

  • Picking provider blindly: each has strengths; match to use case

  • Generating long videos for short ad placements: 30s video for a 6s placement = waste of credits; generate target duration

  • Forgetting failed jobs are free: don't over-engineer retries

  • Polling too aggressively: every 5-10 sec is plenty; faster polling doesn't speed up generation
