Operating guide

The generation stack

What Higgsfield and Lovable actually cost, what they can and cannot do, and which one to reach for per job. Every price here was measured against our own account, not read off a pricing page.

The bottom line.

At our volume, generation cost is a rounding error. A full site's imagery, the entire pending Meta creative set, and ad video all land under $25. Do not subscribe to either tool yet.

Spend the attention on two things instead: use a model ladder (explore at $0.003 a try, finish on the model that has the control you need), and hold the line that Lovable never writes code that ships to octomonic.com.

01Two corrections to numbers I gave you

Both were mine, and both came from trusting the API's dollar field instead of its credit field.

Cheapest still, real cost
$0.003125
I said $0.004. At 0.050 credits it sits below the API's display precision, which rounds up. Cheap calls are overstated by up to 28%.
soul/v2 vs soul/standard
30×, not 23×
I divided the rounded dollars. The credits are 0.050 against 1.500. Budget in credits, treat dollars as display.
Credit rate
$0.0625
Flat across 22 endpoints. Exactly 16 credits per dollar, or $5 per 80 credits.

02The finding that saves you money

The locked models are not a plan gate. Upgrading would not unlock them.

Sora 2, Veo 3.1, Nano Banana, Seedance and FLUX all return 404 model_not_found on our key. Higgsfield's own comparison matrix says those unlock at Plus ($59/mo). It would be natural to buy Plus.

That would be wasted. Our account already holds models the same matrix marks Plus-only, including DoP Turbo, Kling 2.1 Master and Wan 2.5. So we are at Plus-or-better on entitlements and the API still refuses. The Cloud API keeps a per-account allowlist independent of the subscription tier, and their FAQ says as much.

The fix is an email to support@higgsfield.ai, not a purchase. Worth naming in it: two Veo image-to-video paths answer 503 rather than 404, which suggests Veo may be half-provisioned already.

03Which job, which tool, what it costs

Costs at the $0.0625 list rate. On a plan they fall further, but see decision 1.

JobHowCost
Hero image, octomonic.com Explore on soul/v2 until the prompt lands, then finish the winner 2 to 3 times on soul/standard at 4K with the exact aspect ratio. Composite the yellow in our own code, not in the generation. ~$0.33
per finished hero
Section imagery (14 assets) soul/v2 only. Roughly 10 tries per usable asset. No 4K finish needed below hero size. ~$0.44
$0.031 each
Meta static ads
3 concepts × 3 ratios
soul/standard, not v2. It is the only still model exposing the aspect-ratio enum covering 4:5, 1:1 and 9:16. Generate each ratio natively rather than cropping. ~$6.75
largest single line
Meta video ad
5 to 6s vertical
Still first: art-direct frame one on soul/standard at the ad ratio, upload it, animate with dop/lite. Image-to-video inherits the framing, which is the only reliable way to get an on-brand vertical. ~$0.47
per finished clip
Video where motion fidelity matters Same still-first pipeline but kling v2.5-turbo. The only family with negative_prompt and cfg_scale, the prompt-adherence dial. Use when DoP drifts off the product. ~$0.72
Internal animatic hailuo-02, the cheapest moving image we have. Storyboard a motion idea before committing.
Never for a shipped ad: no aspect ratio, no seed, so effectively 16:9 and not reproducible.
$0.090
per 6s
Flagship hero film kling v2.1 master, and only after the shot is fully locked elsewhere. Never iterate here. $1.40
per 5s
Website first draft Lovable. Write the whole brief in Claude Code first, which is free, then paste it as one long opening message. Do not think inside Lovable. $0
~2 of 30 free credits
Three layout variants to compare Three projects in one turn, then deploy each. Deploying is free and returns three live URLs to put in front of a client. $0
~6 free credits
Refining a Lovable draft GitHub sync, then edit locally and push. Lovable picks the push up in seconds. Credits are spent only on generation, never on local editing or deploys. $0
Anything shipping to octomonic.com Our own repo. Harvest structure from a Lovable draft using the free read tools, then rebuild against our token system. $0

Ten exploratory tries on the master model costs $14. The same $14 buys 4,480 cheap stills. That ratio is the whole argument for the ladder.

04Access paths, and which to use

PathVerdictWhy
Higgsfield REST
(our client)
use this Already has the free pre-flight estimate, the download step against the 7-day expiry, and the spend gate. Roughly 40 lines do what the SDK does.
Higgsfield Python SDKdo not adopt Its one real advantage over ours is file upload, and that upload is broken at v0.1.0. Adopting it would also delete our spend gate, since its subscribe() spends the moment it is called.
Higgsfield CLI + Claude Code pluginoptional Real and official. Logs in as an account rather than an API key, and its tokens are short-lived, so it is unsuitable for anything unattended.
Lovable MCPuse this Live for every Claude on this Mac. 40 tools. Reading files, diffs and deploys are all free.
Lovable browser UIunavoidable Some things have no MCP equivalent: connecting GitHub, billing, custom domains, and renaming a workspace. Expect to open a browser for those.

05Decisions

noSubscribe to Higgsfield

Starter is $0.0704 per credit, which is worse than the API's own $0.0625 list rate. Plus only pays for itself above roughly 1,100 credits a month; our entire projected usage is about 130. Plan credits do not roll over, so an unused tier is pure loss. Stay on prepaid.

yesEmail support@higgsfield.ai

Free, and the only documented route to the locked models. Ask specifically for API provisioning of Veo 3.1 and Nano Banana. See section 02 for why upgrading would not work.

yesLog into cloud.higgsfield.ai once

Two minutes, and it closes four unknowns at once: plan, credit balance, concurrency cap, and top-up rates. There is no balance endpoint, confirmed three ways, so the dashboard is the only place these exist. Every number in this guide is a unit price, not a runway.

noLovable Pro, $25/mo

Every paid wall we would hit (custom domain, code download, badge removal) is routed around by GitHub sync, which is free on all plans, plus hosting on our own Vercel. Revisit when generation volume exceeds 30 credits a month, not for features.

yesLovable output never ships to octomonic.com

Not a taste judgement. Lovable cannot import an existing repository, new projects are TanStack SSR rather than our Vite SPA, and its build messages carry no cost estimate and no refund, so every failed pass at accessibility 100 or Hebrew RTL is billed. Harvest ideas with the free read tools; write the code ourselves.

your callReplace per-batch approval with a standing ceiling

At $0.003 a still, asking permission per batch is friction with no protective value. A $25 a month ceiling is more than the entire projected annual creative spend. The code-level gate stays either way, and every batch still gets quoted before it runs.

06What research could not settle

Stated plainly rather than papered over. The first two are the ones that matter.

Do plan credits and prepaid API credits share one pool?The docs imply one balance but never say it. If the API runs on a separate pool, every plan-rate comparison above is irrelevant and the real rate is simply the flat $0.0625. This is the single assumption most worth testing before any purchase.
What is our actual balance, plan and concurrency cap?No endpoint exists. Only the dashboard knows. Until someone logs in we are budgeting against a balance nobody has seen.
Does Lovable Free accept inbound git pushes?The entire $0 workflow rests on this. Git sync is documented on all plans, but Free's in-browser editor is read-only. Test on a throwaway project before promising a client anything.
What do soul/reference and soul/character cost?Neither returned a price. They are the only stills with a seed, so the only reproducible ones, which matters for brand-matched client work. Free to resolve now that upload works.
What parameters does soul/v2/standard accept?It is absent from the OpenAPI spec despite being the docs' own quickstart model, so its schema is unverified. The cheap half of the stills recipe assumes only that it takes a prompt.
Lovable Cloud and AI-gateway rates are unpublished.For any client app hosted on Lovable Cloud this is an unbounded, unquotable line item. Hosting on our own Vercel makes it disappear.
