Higgsfield Alternative for Developers

Looking for a Higgsfield alternative you can build on? ModelsLab is an API: one key for Kling, Seedance, MiniMax H3 and Wan video, plus open-source Wan 2.2 and LTX 2.3 at $0.075 per clip, or with no per-clip charge on the $149/month Open Source Unlimited plan.

Higgsfield vs ModelsLab: the short answer

Higgsfield is best known for its creator app, and it also sells an API at open.higgsfield.ai with per-second video prices. So the honest comparison is API against API. On 2026-09-23 Higgsfield was cheaper for some third-party models, Kling 3.0 above all, while it ran a 50% promotion. ModelsLab was cheaper where it runs the model on its own GPUs.

Choose ModelsLab if you want open-source video at a flat cost, image, voice and LLM endpoints on the same key, or a fixed monthly bill for high volume. Choose Higgsfield if you only need its headline models at its current discounts, or its own models such as Cinema Studio and Soul.

Video API prices, model by model

Per second of output at the base resolution. Higgsfield prices read from open.higgsfield.ai on 2026-09-23; several were promotional that day.

Higgsfield figures are the 'from' prices its API page listed on 2026-09-23, with the list price in brackets where a discount was shown. ModelsLab figures are the base per-second price on each model page; higher resolutions cost more on both. On ModelsLab, third-party calls first use the usage included in a plan from $21/month, then wallet balance.

Where ModelsLab costs less

Open-source video that ModelsLab runs itself. Wan 2.2 and LTX 2.3 cost $0.075 per clip, drawn from the usage included in your plan: about 280 clips on Basic ($21) and 626 on Standard ($47). On the $149/month Open Source Unlimited plan they have no per-clip charge, with 15 requests in parallel. Measured on production traffic from 19 to 23 September 2026, a 12-second LTX 2.3 clip had a median render time of 42 seconds.

ModelsLab also runs its own MiniMax H3 builds at $0.050 per second, against $0.0715 on Higgsfield and $0.096 for the MiniMax-hosted version.

Where Higgsfield costs less

Kling 3.0, LTX 2.5 Pro, the MiniMax-hosted H3 and, by a fraction of a cent, Seedance 2.0 while Higgsfield's promotions last. On 2026-09-23 Kling 3.0 was $0.042 per second on Higgsfield and $0.084 on ModelsLab. If Kling is most of your spend, compare the two again on the day you decide.

How to work out a real cost

Multiply the per-second price by the clip length, then by the resolution factor on the model page. A 5-second Kling 3.0 clip in standard mode on ModelsLab is 5 x $0.084 = $0.42. On Basic and Standard, third-party calls first use the usage included in the plan, then wallet balance. The $149 Unlimited plan covers only the self-hosted models, so third-party calls on it are billed from wallet balance.

For developers, yes. Higgsfield is best known for its creator app, and it also sells an API at open.higgsfield.ai. ModelsLab is API-first: one key covers the same third-party video models plus open-source video, image, audio and LLM endpoints, and a flat $149/month plan covers the self-hosted open-source models.

Yes. On 2026-09-23 open.higgsfield.ai listed per-second API prices for Kling 3.0, Seedance 2.5 and 2.0, MiniMax H3, Wan 3.0, LTX 2.5 and others. If you only need those models and Higgsfield's current discounts, its API is a reasonable choice.

It depends on the model. On 2026-09-23 Higgsfield's API listed Kling 3.0 at $0.042 per second (a 50% promotion) against ModelsLab's $0.084, so Higgsfield was cheaper for Kling. ModelsLab was cheaper where it runs the model itself: its own MiniMax H3 build is $0.050 per second against $0.0715, and Wan 2.2 and LTX 2.3 are $0.075 per clip or unlimited on the $149 plan.

Self-hosted open-source video: Wan 2.2 and LTX 2.3 at $0.075 per clip, and ModelsLab's own MiniMax H3 text-to-video build at $0.050 per second. These are the models the $149 Open Source Unlimited plan covers without per-call charges, with 15 requests in parallel.

Yes. The same key calls /api/v7/video-fusion for video, the image endpoints, text to speech and voice cloning, and the OpenAI-compatible LLM endpoint at /api/v7/llm.

Per call. On Basic ($21/month) and Standard ($47/month) the usage included in the plan is used first, then wallet balance; on the $149 Unlimited plan third-party calls are billed from wallet balance. Most are priced per second of output, scaled by resolution, so a 5-second Kling 3.0 clip in standard mode costs about $0.42. The $149 Unlimited plan does not cover third-party models.
