Which engine makes each picture, film and voice in Brew, in what order they fall back, what each costs, what each is good at, and the rule that drafts are cheap and automatic while finals are paid, quoted and made only on a person's yes.

Higgsfield first where routed, Vertex second, Brew's own cut-out

Picture
gemini-2.5-flash-image, then gemini-3-pro-image, then OpenAI gpt-image-1; GPT Image goes first when the jam's image chip picks it, but never with a look reference
veo-3.1-fast-generate-001; a filtered clip is tried once with the plainest motion; an outage or quota moves to Veo 3.1; a priced job never falls to the dearer Veo

Partners are interchangeable; data/engines.json orders them per capability, and a partner that is not connected is skipped, never faked brew/jam2/engines.js:1-9.

Higgsfield goes live once HF_API_KEY_ID and HF_API_KEY_SECRET exist in Secret Manager; deploy adds them only if the secret exists brew/deploy.sh:37. On 23 Oct the Higgsfield API was funded with $100 and the keys were not yet in Secret Manager memory brew-jam-v2.

Studio styles
The library is data/studio-styles.json plus Higgsfield's own ad presets brew/jam2/studio.js:25-31.
Image groups: product shot with 13 styles, Higgsfield ads presets, marketplace with 4, graphic with 3, Amazon A+ with 5 brew/data/studio-styles.json.
Video groups: UGC with 6 styles of 10 to 12 s, motion with 9 of 5 s, recreate with 1, TikTok with 3 including a 30 s viral short brew/data/studio-styles.json.
Studio opens on three styles picked from the card's angle and recipe brew/jam2/studio.js:34-60.
Each style has one example picture made once on a neutral bottle: 43 made for $1.64 memory brew-setup-v2.
Sloosh finals
Models on Sloosh: Nano Banana Pro, Nano Banana 2, GPT Image 2.5, Flux 2 Pro at 1K only, Ideogram 4.5, Seedance 2.5 and 2.0, Gemini Omni; no Veo memory brew-sloosh-finals.
When Sloosh cannot quote an image, the same button makes it on Gemini at zero credits, labelled; a video falls back to Veo on a Gemini still; Spaces have no fallback brew/finals.js:8-13.
A reel over the day's room is asked one resolution down, never under 720p, before Veo brew/finals.js:155-160.
Strengths and lessons
Nano Banana Pro sets the words in the picture, so the Studio overlay must not set them again memory brew-sloosh-finals.
Vertex ignores a 2K image size; multi-item kits failed fidelity on Gemini 3 Pro Image memory brew-jam-v2.
Veo's filter reacts to people, words and fast action; sleep words with a woman on camera got the output deleted; some generated faces are refused on input; Veo standard filtered far more than fast brew/media.js:51memory ugc-factory-pipeline.
Seedance takes a start frame or references, not both; Kling needs a start frame; Omni, Grok and MiniMax refuse any sound setting memory brew-sloosh-finals.
The 360 turn invents the back label when no photo shows it memory brew-jam-v2.
A UGC run once cast a Western presenter for an Indian brand; art direction now gets the market memory brew-jam-v2.

How we do it
Change partner order in data/engines.json, never in code brew/data/engines.json.
Before a new Sloosh call, read data/sloosh-tools.json; re-run the probe when Sloosh changes a schema memory brew-sloosh-finals:
node tools/sloosh-probe.mjs
A new style needs its example picture, which is paid; ask first memory brew-setup-v2:
node tools/style-examples.mjs --only <id>
Never run paid generations while building; verify with mock runs and ask before one minimal paid probe memory no-spend-while-building.
Test paid Studio and Sloosh video on Arata, Nutrova or Puma India with the team's yes, never on Cozy memory brew-jam-v2memory brew-viral-remakes.

Proposed
media.js tried
Brew calls Higgsfield's keyed REST API (84 workflows). Marketing Studio video modes, the product-photoshoot and marketplace-card prompt helpers, audio, upscale, background removal, Nano Banana, Veo, Seedream and GPT Image 2.5 are CLI or MCP only, on a personal login; the terms make one login for many brands risky memory brew-higgsfield-wiring.
The catalog refresh (tools/hf-catalog.mjs) refuses to write an empty or shrunken catalog, or one missing a routed workflow brew/tools/hf-catalog.mjsgit 91c392b.
Open
Higgsfield keys. Proposal: add HF_API_KEY_ID and HF_API_KEY_SECRET to Secret Manager so Studio runs on its first choice, with the existing per-make price and yes.
What is a Sloosh credit in dollars? No source gives it. Proposal: write the plan price into Finance and show finals in dollars to the team.
Sloosh or Higgsfield for finals? Both make finals-grade work. Proposal: run the partner bench on 10 briefs and keep the cheaper one that passes the eval bar.
Higgsfield Enterprise for the CLI-only tools? Needs a word with Higgsfield sales before Brew wires Marketing Studio video or audio. Waits on Param memory brew-higgsfield-wiring.
