dpnp and Taichi compared on what their own pages say, how each is installed, what each costs and what to check before choosing either one or PyOverdrive.

dpnp and Taichi compared on what each one's own pages say it does, how each is installed, what is published about cost and what to check, next to PyOverdrive. The table sets the license, price and install route for each side by side.

| Option | What it is | License | Price | Install |
|---|---|---|---|---|
| dpnp | Described as a library on its page [^1] | BSD-3-Clause license [^1] | not published | conda, mamba or pip package managers [^1] |
| Taichi | A language built into Python for writing portable, high-performance parallel programs [^2] | not published | not published | pip install taichi -U [^2] |
| PyOverdrive | Patches supported NumPy functions so existing code uses faster paths [^3] | Open source under the MIT License [^3] | not published | pip, straight from the GitHub repository [^3] |

## The short answer

dpnp is described on its page as a library, and it can be installed with conda, mamba or pip package managers [^1]. The sources here say nothing more about what it does, so check its repository before you rely on it. Taichi's ahead-of-time mode enables deployment on platforms without Python, including PCs, mobile devices and web browsers [^2]. PyOverdrive patches supported NumPy functions so your existing code uses faster paths. [^3] Calls it does not support run on stock NumPy [^3].

On needs, Taichi's sources cover running a program on PCs, phones and browsers without Python [^2]. PyOverdrive's claims cover faster paths for existing NumPy code [^3]. dpnp's sources name its license and its install routes, but they do not say which needs it meets, so this page does not match it to one.

## What Taichi is built for

dpnp's sources say it is published under the BSD-3-Clause license [^1] and can be installed with conda, mamba or pip package managers [^1]. Those are the only facts available for it here, so this page names no features for it.

Taichi's sources describe an ahead-of-time mode that enables deployment on platforms without Python, including PCs, mobile devices and web browsers [^2]. Taichi can be installed with pip [^2].

## What PyOverdrive is built for

PyOverdrive is made by the team that publishes this site. Calling pyoverdrive.enable() patches supported NumPy functions so your existing code uses faster paths, and calls it does not support run on stock NumPy. [^3] A faster path runs only when a check confirms the input is in its measured range; anything else, or a fast path that raises an error, goes to stock NumPy [^3].

Threaded paths for sine, cosine, tangent, exponential, logarithm and tanh run on float arrays stored as one continuous block of memory, above a size floor set for each operation and data type [^3]. For large stacks of 3x3 matrices, np.linalg.qr uses a vectorized closed-form formula, and np.linalg.eigvalsh has closed-form paths for 2x2 and 3x3 batches above a size threshold [^3]. Large np.einsum calls go through NumPy's own optimize=True planner once they pass a measured size threshold [^3]. np.isin on one-dimensional string or object arrays can use hash-set membership, a faster lookup method [^3].

## Pricing and fees

The sources here give no price for dpnp, so none is published on this page. Its license is BSD-3-Clause [^1], and its sources state no cost for installing it.

No price or paid plan is stated in the sources for Taichi, so none is published here. Its sources give an install command, pip install taichi -U [^2], but no cost for it.

PyOverdrive's claims state no price, so none is published here. It is open source under the MIT License [^3]. Each project's own pages are the place to confirm current pricing and terms.

## Setting it up and daily use

dpnp can be installed with conda, mamba or pip package managers [^1]. The sources here say nothing about using it day to day. Taichi can be installed with pip install taichi -U [^2], and its ahead-of-time mode enables deployment on platforms without Python [^2].

PyOverdrive is installed with pip straight from the GitHub repository [^3] and needs Python 3.12 or newer [^3]. Its version is 1.0.0 and its status is Beta [^3]. Running python -m pyoverdrive --demo times the headline operations with stock NumPy and with PyOverdrive on your machine, in about 20 seconds [^3]. Running python -m pyoverdrive --selfcheck compares every fast path with stock NumPy on your own machine [^3], and python -m pyoverdrive --calibrate re-times the threaded paths on your CPU and switches off any that do not pay there [^3]. pyoverdrive.explain() tells you which path a call would take and why, without running the call [^3]. You can turn off one fast path with disable_path() or PYOVERDRIVE_DISABLE, or call pyoverdrive.disable() to restore the original NumPy functions [^3].

## Things to check before you choose

Check the license against your project. dpnp is under the BSD-3-Clause license [^1] and PyOverdrive under the MIT License [^3]. Taichi's license is not stated in the sources, so look it up on its own pages.

Check your Python version. PyOverdrive needs Python 3.12 or newer [^3].

Check your operating system. PyOverdrive is marked OS independent, and its test suite has been run on Windows and on Linux x86-64 [^3]. The sources here say nothing about which operating systems dpnp supports.

Check where your program has to run. If it must run on phones or in a browser without Python, Taichi's sources cover that [^2]. Ask whether your code calls the NumPy functions PyOverdrive supports, since it only changes those [^3].

## How to choose

If you want existing NumPy code to use faster paths with stock NumPy as the fallback, PyOverdrive's claims describe that [^3] [^3].

If you need a program to run on PCs, mobile devices or web browsers without Python, Taichi's sources describe that [^2].

If you want a library under the BSD-3-Clause license that installs through conda, mamba or pip, dpnp's sources state both [^1] [^1].

If you want to check on your own machine how PyOverdrive compares with stock NumPy, its demo times the headline operations in about 20 seconds [^3].

## Frequently asked questions

### Is dpnp free to use?

dpnp is published under the BSD-3-Clause license [^1]. The sources available here state no price for it, so none is published on this page. Before you rely on dpnp for paid work or a commercial product, check the project's own pages for its current terms and any cost. This page cannot confirm either one.

### Does Taichi have a paid plan?

The sources available here state no price or paid plan for Taichi, so none is published on this page. Its pages do give an install route, pip install taichi -U [^2], and a community of over 200 contributors from around the world [^2]. For current pricing, check Taichi's own pages before you decide, since this page cannot confirm any cost.

### How do you install PyOverdrive?

You install PyOverdrive with pip straight from the GitHub repository [^3]. It needs Python 3.12 or newer [^3]. Once it is in place, calling pyoverdrive.enable() patches supported NumPy functions so your existing code uses faster paths [^3]. Running python -m pyoverdrive --selfcheck then compares every fast path with stock NumPy on your own machine [^3].

### Can PyOverdrive fall back to stock NumPy? [[c:pyoverdrive-stock-fallback]]

Yes. [^3] A fast path runs only when a check confirms the input is in its measured range, and anything else goes to stock NumPy [^3]. A fast path that raises an error also goes to stock NumPy [^3]. Calls PyOverdrive does not support run on stock NumPy as well [^3]. To see which path a call would take and why, pyoverdrive.explain() reports that without running the call [^3].

### Which of dpnp or Taichi can run in web browsers?

Taichi's ahead-of-time mode enables deployment on platforms without Python, including PCs, mobile devices and web browsers [^2]. The sources for dpnp say nothing about where it can be deployed, so this page does not say it runs in a browser. Check dpnp's own pages before you choose it for that use.
