Modellix vs WaveSpeed are both single-key API aggregators for AI media generation, and the honest answer to which one you should pick is: it depends on whether you optimize for catalog breadth or for pricing transparency and observability. WaveSpeed offers the largest catalog in the category — 1,000+ models across image, video, audio, 3D and LLMs, plus consumer tools — while Modellix offers a smaller, fully price-transparent catalog (210+ media models plus an LLM gateway) with parameter-level price tables and per-call logs.
This is from Modellix, so here is the disclosure up front: we have a commercial interest in this comparison, and we are going to show you where WaveSpeed genuinely beats us. Every WaveSpeed fact below was checked against its live pricing page, docs and homepage on August 12, 2026. Where a claim is a vendor claim rather than something we could verify, we say so.
Modellix vs WaveSpeed at a glance
| Dimension | WaveSpeed | Modellix |
|---|---|---|

| Call observability | Not detailed publicly | Per-call logs with cost and latency |
Both platforms verified live on August 12, 2026. Catalog and pricing change frequently on both sides.
What each platform actually is
WaveSpeed (wavespeed.ai) is a unified AI media generation platform. Its own materials describe 1,000+ models accessed through one API key, with a REST API, Python and JavaScript SDKs, a CLI, ComfyUI and N8N integrations, a desktop app, and browser tools. It is unusual among API aggregators because it also runs consumer-facing products — image and video generators, a desktop app, and a catalog of free tools — which is how it built a large organic footprint (third-party traffic estimates put it near 63,000 monthly organic visits, with about 2,000 referring domains, as of July 2026).
Modellix (modellix.ai) is a model-as-a-service aggregator focused on media generation. It exposes 210+ image, video and audio models from 12 provider brands (Alibaba, Kling, Google, ByteDance, Vidu, MiniMax, PixVerse, xAI, Skywork, OpenAI, Microsoft, Reve) behind one API key, with pay-as-you-go billing, a browser Playground on every model page, webhooks, a CLI, and a free File API for uploads. As of August 2026 it also operates a separate LLM gateway at llm.modellix.ai with OpenAI- and Anthropic-compatible endpoints.
Both are distribution layers, not model developers: neither trains the models it hosts. That means the real comparison is about catalog, pricing structure, developer experience, and trust — not about who invented better models.
Model catalog: breadth versus focus
The catalog gap is real and WaveSpeed wins it. 1,000+ models versus 210+ is a five-to-one difference, and it shows up in the long tail: WaveSpeed’s model directory is deeper on nearly every family both platforms carry. For example, WaveSpeed lists over 140 Kling model pages (through V3 and motion-control variants) against roughly 40 Kling routes on Modellix — a difference we confirmed from third-party sitemap counts in July 2026 rather than from our own catalog. The same pattern holds for Wan, Seedance and Vidu families.
That breadth matters if your product needs an obscure variant, a niche capability (3D generation, avatars, speech synthesis), or a model that one platform adds first. New releases also land on both sides quickly — both WaveSpeed and Modellix were showing Seedance 2.5-era models in August 2026 — but WaveSpeed’s pipeline for adding and listing models is visibly larger.
Breadth has a cost, and it is not hidden: a 1,000+ model catalog is harder to audit. Which variants are maintained? Which prices changed this week? Which model is the current default for a task? On Modellix every model page shows a routing note (“use this model for X, prefer that one for Y”), a per-parameter price table, and a recommendation of what to use instead — the catalog is smaller partly because it is curated. For a team that cares about being able to justify every model call in a review, that trade-off is worth counting.
Pricing: per-parameter transparency versus headline rates
Both platforms are pay-per-use with no monthly fee, and both publish prices publicly. The difference is the level of granularity.
WaveSpeed’s pricing page lists one headline price per model. Modellix’s model pages list a price table per model, with different prices for different resolutions, audio settings, image sizes, and prompt options. WaveSpeed’s own page highlights entry examples of $0.005 per image (Z-Image Turbo) and $0.01 per second (Wan 2.2 Ultra Fast); among the overlapping models verified today, Modellix’s low-end displayed prices are $0.0092 per image (Z-Image Turbo at default settings) and $0.0580 per second (Kling V3 at 720p, audio off). Neither is “cheaper” as a blanket statement — a per-second video price at 720p is not the same product as one at 4K, and a $/image price at 512px is not the same as one at 4K. But the comparison below is useful: it shows what each platform displays for the same named models, checked from live pages on August 12, 2026.
| Model | Unit | WaveSpeed listed | Modellix displayed (live) |
|---|---|---|---|
| Nano Banana 2 | per image | $0.07 | $0.0403–$0.1248 (by image size) |
| Seedream 4.5 | per image | $0.04 | $0.0414 |
| Z-Image Turbo | per image | $0.005 | $0.0092–$0.0185 (prompt extend on/off) |
| Seedance 2.0 | per second | $0.10 (Fast) | $0.0805–$0.8970 (by resolution) |
| Kling V3 / 3.0 | per second | $0.084 (3.0 Std) | $0.0580–$0.2898 (by resolution + audio) |
| Veo 3.1 Fast | per second | $0.15 | $0.0805–$0.2415 (by resolution) |
Sources: WaveSpeed pricing and Modellix’s pricing page and model pages (e.g. Nano Banana 2, Kling V3), all accessed August 12, 2026. WaveSpeed’s column is its headline list price; Modellix’s is the full displayed range. A matched-parameter comparison — same model, same resolution, same audio setting — is the only honest way to compare a specific workload.
Low-end displayed price per unit for overlapping models, both platforms, August 12, 2026. Units are per image or per second as each model is billed; image and second units are not interchangeable. The chart shows entry prices only — resolution-matched costs may differ.
The pattern you should take away is not “Modellix is cheaper.” It is that Modellix’s displayed prices are parameterized, so you can budget precisely before you build, while WaveSpeed’s headline numbers are starting points that vary by settings. On several of the overlapping models checked today, Modellix’s low-end displayed price is below WaveSpeed’s headline (Nano Banana 2, Seedance 2.0, Kling V3, Veo 3.1 Fast); on a couple (Seedream 4.5, Z-Image Turbo) WaveSpeed’s headline is lower. Always recheck the live pages before committing budget — both platforms change prices without notice.
The free-trial story also differs. WaveSpeed gives new accounts $1 in credit with no card required (its FAQ notes some premium models are not available with trial credit). Modellix’s docs do not currently publish a free-credit tier; instead, first top-ups earn a 10% discount per tier (up to six tiers), and every model can be tested in the browser Playground before you fund an account. Both platforms tier their rate limits by account funding level: WaveSpeed has Bronze/Silver/Gold/Ultra levels tied to top-up size, and Modellix publishes concurrency and RPM entitlements per top-up tier.
Developer experience: API, SDKs, and tooling
On the API surface, both platforms use the same mental model: submit a generation task, poll or receive a webhook when it completes. Both offer REST endpoints, streaming where the model supports it, and webhook notifications. Both are documented with runnable examples.
Where they diverge:
- Integration surface. WaveSpeed ships REST, Python SDK, JavaScript SDK, CLI, ComfyUI and N8N integrations, and a desktop app — the widest set of access paths in the category. Modellix ships REST, a CLI (
modellix-cli), an Agent Skill for coding agents, webhooks, a Playground with one-click export, a docs-retrieval MCP, and a free File API for uploading input media. - Observability. Modellix records per-call logs with input, output, cost and latency — useful for cost attribution when one API key is shared across a team or a product. WaveSpeed does not detail call-level logging in its public docs.
- Result retention. Modellix stores generation results for 7 days by default; WaveSpeed’s retention policy is not stated in its public docs. Both expect you to download results promptly.
- LLM access. WaveSpeed lists LLM models (Claude, GPT, Gemini, Qwen, DeepSeek) on its pricing page alongside media models. Modellix’s LLM gateway offers OpenAI-compatible Chat Completions and Responses plus Anthropic-compatible Messages, with displayed discounts of 3–20% off list prices on the models it carries. If you need one account for both media and LLM calls, both platforms now qualify — verify the specific models each carries before assuming overlap.
One caveat on integration depth: WaveSpeed’s SDKs and ComfyUI/N8N support are real and documented, but they are also what a large catalog vendor is expected to provide. For a simple image-or-video pipeline, both platforms are roughly equivalent; the DX difference shows up when you need per-call cost tracking (Modellix) or a no-code/desktop workflow (WaveSpeed).
Where WaveSpeed genuinely wins
To be direct about it:
- Catalog breadth. 1,000+ models, including 3D, avatars, speech and creative tools, plus deeper coverage of the Chinese model families both platforms carry. If you need a niche variant or want to explore models quickly, WaveSpeed is the better home.
- Consumer products. Image generator, video generator, tools, apps and a desktop app mean a team can try models without writing code, and a product team can ship a consumer surface off the same account.
- LLM + media in one place. Its pricing page lists both media and LLM models, so a single integration can cover text, image, video and audio.
- Trial credit. A $1 no-card credit is a real, friction-free way to validate the API. (We could not find an equivalent published free credit on Modellix.)
- Scale signals. WaveSpeed states sub-second image generation, up to 4x faster video rendering than alternatives, 99.99% uptime, and SOC 2 Type II compliance. These are vendor claims — we did not independently verify them — but they are public commitments, and the platform’s third-party traffic and referring-domain footprint (about 63,000 monthly organic visits and ~2,000 referring domains per July 2026 third-party estimates) are far larger than Modellix’s.
Where Modellix wins — and its honest limits
Modellix’s advantages are the ones a small engineering team tends to feel during a build, not during a demo:
- Parameter-level price tables on every model page, with the exact price for the exact resolution/audio/size you will call. Budgets are computable before the first request.
- Per-call logs with cost and latency for every request under one key — useful for internal cost attribution and for auditing what a product actually spends.
- A smaller, curated catalog with routing guidance: each model page says what it is best for and what to prefer instead, which removes a real decision cost that a 1,000+ model catalog creates.
- Discounted LLM gateway with clearly displayed percentage savings on carried models.
- Free File API for uploading input media (no charge, ~7-day retention), and Playground export to webhook/Drive/Dropbox.
- 10% first-top-up discount per tier for funded accounts.
Its honest limits: the catalog is roughly one-fifth the size; there is no consumer/desktop app; results expire after 7 days; no published free-credit tier; and the brand is young (the domain was registered at the end of 2025), so enterprise buyers will find fewer references and less third-party validation than WaveSpeed’s.
When to pick WaveSpeed
Pick WaveSpeed if your workload needs any of these: the broadest model catalog (including 3D, avatars, speech, or niche variants), consumer-facing generation tools and a desktop app for your own team, LLM and media models from one account, a no-card trial to validate the API quickly, or an established platform whose scale claims and enterprise options (custom plans, SLAs) matter to your stakeholders. If a required model exists on WaveSpeed and not on Modellix, the decision is already made.
When to pick Modellix
Pick Modellix if your decision hinges on cost predictability and observability: you want to budget from exact per-parameter prices before building, you need per-call cost and latency logs for attribution, you prefer a curated catalog where every model page explains what it is for, or you want a discounted LLM gateway alongside your media calls. If you are migrating from another aggregator and the models you need are on both platforms, Modellix’s displayed entry prices were lower on several overlapping models at the time of writing — worth pricing out for your actual mix before deciding.
How to test both before committing
You can validate both platforms in under an hour without a card on WaveSpeed’s side:
- WaveSpeed: sign up, use the $1 trial credit, run one image and one short video through the API or the browser tools. Note which premium models the trial excludes.
- Modellix: open the model directory, run the same models in the Playground without funding an account, and export the exact price table for the resolution you will ship.
- Run the same prompt on the same model family (e.g. Nano Banana 2, Seedance 2.0, Kling V3) on both, at the same resolution, and compare billed cost and end-to-end latency for your actual workload — not for a single short clip.
- Check rate tiers against your expected concurrency: WaveSpeed’s account levels and Modellix’s published entitlements both tie limits to funding, so pick the tier your spend actually lands in.
FAQ
Which is better, Modellix or WaveSpeed?
Neither is universally better. WaveSpeed wins on catalog size, consumer tooling, and LLM-plus-media breadth; Modellix wins on per-parameter pricing transparency, per-call observability, and a curated catalog. Choose by workload, not by brand.
Is WaveSpeed cheaper than Modellix?
It depends on the model and parameters. On the overlapping models checked August 12, 2026, WaveSpeed’s headline price was lower for Seedream 4.5 and Z-Image Turbo, while Modellix’s low-end displayed price was lower for Nano Banana 2, Seedance 2.0, Kling V3 and Veo 3.1 Fast. Recheck live pages for your exact mix.
Can I migrate from WaveSpeed to Modellix?
Mostly yes — both expose REST APIs with the same async task pattern, and both host the major media families (Kling, Seedance, Wan, Nano Banana, Veo). Migration is a client-side change: swap base URL, key, and model IDs, then re-verify prices and rate limits. Modellix’s per-call logs make the cost side of that migration easier to audit.
Does Modellix have LLM models?
Yes — as of August 2026, Modellix operates an LLM gateway at llm.modellix.ai with OpenAI-compatible and Anthropic-compatible endpoints and displayed discounts of 3–20% on carried models.
Does WaveSpeed have a free tier?
WaveSpeed does not offer a permanent free tier; it grants $1 in trial credit to new accounts (no card required), with some premium models excluded. Modellix does not publish a free-credit tier either; it offers Playground testing without funding and a 10% first-top-up discount per tier.
