Short answer: on Motionflare's video-generation agent, Claude Haiku 5.5 was about 3× cheaper and 2.6× faster than DeepSeek V4.1 Flash, with comparable output quality. Across 8 real projects tested on October 8, 2026, Haiku 5.5 averaged $0.046 and 4.6 minutes per video. DeepSeek V4.1 Flash averaged $0.142 (at its off-peak rate) and 11.8 minutes. Haiku was cheaper on all 8.
The surprise is where the savings come from. Per token, the two models cost about the same. Haiku 5.5 wins because it finishes the same job with one third of the output tokens.
Same website, same prompt, same pipeline. Left: DeepSeek V4.1 Flash. Right: Claude Haiku 5.5.
Why we ran this test
Since September, DeepSeek V4.1 Flash has been the default model behind Motionflare videos. We picked it for one reason: it was the cheapest model that consistently produced a video worth shipping (see Changelog 06).
Anthropic released Claude Haiku 5.5 on October 7, 2026, positioned as its cheapest and fastest small model. A per-token price sheet can't tell you what a model costs on a real workload, so we replayed real projects through both.
How we tested
Motionflare turns a website or a written brief into a short animated video. Each video is produced by a multi-step agent, and every step is an LLM call:
- Planning: read the source and plan the video, section by section.
- Sections: write the animation code for each section.
- Review: a reviewer pass checks the rendered result.
- Repair: fix what the reviewer flagged.
We took 8 projects that real users had made in production and replayed their exact inputs on our development environment, once with each model. Everything else was held fixed: same code, same prompts, same settings. The 8 inputs were 5 websites and 3 written briefs (in English, Spanish and Arabic). Each produced a video of 10 to 15 seconds.
Cost is the LLM bill for the whole video, computed from the token counts each provider reported, at each provider's published price. Time is wall-clock from start to finished video.
Results
Average per video
| DeepSeek V4.1 Flash | Claude Haiku 5.5 | Difference | |
|---|---|---|---|
| LLM cost (off-peak) | $0.142 | $0.046 | 3.1× cheaper |
| LLM cost (DeepSeek peak hours) | $0.283 | $0.046 | 6.2× cheaper |
| Time to generate | 11.8 min | 4.6 min | 2.6× faster |
| Output tokens | 229k | 75k | 3.1× fewer |
Every project
| Project | DeepSeek cost | Haiku cost | Cheaper | DeepSeek time | Haiku time |
|---|---|---|---|---|---|
| Website 1 | $0.115 | $0.047 | 2.4× | 9.6 min | 5.1 min |
| Website 2 | $0.126 | $0.049 | 2.6× | 12.8 min | 4.9 min |
| Brief (Arabic) | $0.120 | $0.037 | 3.3× | 10.3 min | 3.5 min |
| Brief (Spanish) | $0.202 | $0.051 | 4.0× | 13.2 min | 4.8 min |
| Website 3 | $0.150 | $0.044 | 3.4× | 12.0 min | 4.1 min |
| Brief (English) | $0.196 | $0.050 | 3.9× | 15.8 min | 5.8 min |
| Website 4 (Dutch) | $0.065 | $0.032 | 2.0× | 7.1 min | 3.3 min |
| Website 5 (the video above) | $0.159 | $0.056 | 2.9× | 13.6 min | 5.1 min |
DeepSeek costs in this table use its off-peak rate. Haiku 5.5 was cheaper on every project, by 2.0× to 4.0×, and faster on every project, by 1.9× to 2.9×.
Why Haiku 5.5 is cheaper: tokens, not price
Here are the published prices per million tokens:
| Per 1M tokens | DeepSeek V4.1 Flash (off-peak) | DeepSeek V4.1 Flash (peak) | Claude Haiku 5.5 |
|---|---|---|---|
| Input | $0.15 | $0.30 | $0.10 |
| Cached input | $0.003 | $0.006 | $0.01 |
| Output | $0.60 | $1.20 | $0.50 |
Off-peak, Haiku 5.5 is only slightly cheaper per token, and DeepSeek's cached input is actually cheaper. On a price sheet this looks like a tie.
On a real workload it isn't. An agent that writes code spends most of its bill on output tokens, and DeepSeek V4.1 Flash wrote 229k output tokens per video against Haiku 5.5's 75k. Same job, a third of the writing. Fewer tokens is also why Haiku finishes faster.
The lesson for anyone choosing a model for an agent: compare cost per finished task, not cost per token. A model that is terse and gets to the answer can beat a model with a lower list price.
A note on DeepSeek's peak pricing
DeepSeek bills on a clock. On weekdays from 01:00 to 04:00 and 06:00 to 10:00 UTC, its rates double. This test happened to run inside a peak window, so the raw bill showed DeepSeek at $0.283 per video, 6.2× Haiku's cost.
That is not a fair headline. Most of our production traffic lands off-peak, so every comparison in this post uses DeepSeek's off-peak rate unless it says otherwise. If your workload runs during Asian business hours or European mornings, the gap you see will be closer to 6×.
Limitations
- 8 projects, one run each. Generation is not deterministic, and a different set of inputs could shift the averages.
- Quality is our judgment, not a benchmark score. We reviewed every pair and found the output comparable. The video above is one real pair, unedited, so you can judge it yourself.
- One kind of workload. This is an agent that writes animation code. A task with long outputs that can't be shortened may see a smaller gap.
- Reasoning effort. Haiku 5.5 wrote its sections at low reasoning effort in this test. Our production settings have since changed, and results at other effort settings may differ.
What we changed
Claude Haiku 5.5 is now the default model for new videos on Motionflare. DeepSeek V4.1 Flash is still available in the model picker. Both cost the same 1× credits per scene, so the switch made videos faster for users and cheaper for us to run.
You can try it by turning any website into a video at motionflare.ai.
FAQ
Is Claude Haiku 5.5 cheaper than DeepSeek V4.1 Flash?
Per token, only slightly: $0.10 input and $0.50 output per million tokens for Haiku 5.5, against $0.15 and $0.60 for DeepSeek V4.1 Flash off-peak.

Is Claude Haiku 5.5 faster than DeepSeek V4.1 Flash?
Yes. In our test Haiku 5.5 finished a video in 4.6 minutes on average against 11.8 minutes for DeepSeek V4.1 Flash, 2.6× faster, and it was faster on all 8 projects.
Is the output quality the same?
In our review, yes: we found the two models' videos comparable.
Which model should I use for an AI agent?
Measure cost per completed task on your own workload. For our code-writing agent, Claude Haiku 5.5 beat DeepSeek V4.1 Flash on both cost and speed, as of October 2026.
