I really enjoy the Rumi and Hafez voices; they capture a unique abstract texture that feels like genuine poetry. The browser version is super easy to use. My only hesitation is the small 32-character memory window. It makes sustained conversation difficult, but for quick bursts of inspiration, it works wonderfully. The integer-only approach adds a distinct charm to the output.

The engineering behind 8bitGPT is remarkably well-documented and impressive. The team achieved a ~43x optimization to fit the model into 64 KB, using techniques like KV caching and quarter-square multiplication via table lookups. The hand-written 6502 assembly further reduces latency, though the context window remains limited to 32 tokens. This architecture prioritizes texture over coherent prose, creating a dream-like association effect. The open-source pipeline allows for deep technical scrutiny, making it a valuable resource for understanding minimal viable neural networks on constrained hardware. It effectively captures the Sufi verse aesthetic through precise integer arithmetic.
The browser version offers instant access, while the emulated Commodore 64 run provides an authentic 1 MHz experience. The JavaScript port is convenient, but the real .prg file captures the original hardware feel much better for enthusiasts.
It seems cool, but the site doesn't clearly state how many characters or tokens you get per session. The context window size is listed as a question mark, which feels like a missing detail. For a technical project, I need to know the exact limits before committing time to test the voice options.
The convenience of running 8bitGPT directly in my browser is genuinely impressive. I love that this tiny model, with its roughly eighteen thousand weights, requires no server setup or complex configuration. It loads instantly on any device, allowing me to pick a voice and start typing immediately. The fact that this integer-only architecture runs smoothly on JavaScript makes the experience seamless and accessible, turning a niche technical demo into a delightful, on-demand creative tool that feels truly portable and effortless.

About 8bitGPT
8bitGPT is a small-scale GPT model designed to run on a 1982 Commodore 64 computer, using around 18,000 integer-only weights on a 1 MHz MOS 6502 chip. The project offers two ways to interact with the model: a browser-based JavaScript port that runs instantly on any device, and an emulated Commodore 64 environment that boots the hand-optimized .prg program. Users can select different output voices, including styles inspired by Rumi & Hafez and Shakespeare, and provide a starting word to let the model generate text in a free-association style. The model's text-generation voices are trained on actual translations, allowing the tiny model to approximate the texture of the source material as evocative, abstract dream-babble. The project draws conceptual inspiration from Hamid Ismailov's novel "We, Computers," which imagines a 1980s machine generating Sufi-influenced poetry.
