「開発者は、1976 年の Zilog Z80 CPU 搭載システム上の 64KB の RAM で実行できる「会話型 AI」を開発しました。小さなチャットボットと 20 問の推測ゲームを備えています。

由緒あるZilog Z80 CPUは1976年から存在し、電卓や家庭用コンピュータからアーケード筐体まで、あらゆる機器に搭載されてきました。しかし、この8ビットマイクロプロセッサは、現在使用されているCPUと比べると、必ずしも高性能とは言えません。そこで、開発者のHarryR氏が、この名高いマイクロプロセッサ用の実用的な「AI」、Z80-μLMを開発しました。

⁉️ [HarryR] はチューリングテストには合格しないと断言していますが、ちょっと面白いですね。ちなみに、Z80 の価格は AI の影響を受けません 。⁉️ 」：

👾According to the readme file, "Z80-μLM is a 'conversational AI' that generates short character-by-character sequences, with quantization-aware training (QAT) to run on a Z80 processor with 64kb of RAM." [HarryR]'s goal is to see how small an AI project can go, while still having a "personality". Can the AI be trained and fine-tuned? It seems that [HarryR] has done it in just 40KB, including inference, weights, and chat style user interface.👾 ⁉️[HarryR] has kindly detailed the features of this Z80 AI project⁉️ • Trigram hash encoding: Input text is hashed into 128 buckets - typo-tolerant, word-order invariant • 2-bit weight quantization: Each weight is {-2, -1, 0, +1}, packed 4 per byte • 16-bit integer inference: All math uses Z80-native 16-bit signed arithmetic • ~40KB .COM file: Fits in CP/M's Transient Program Area [TPA] • Autoregressive generation: Outputs text character-by-character • No floating point: Everything is integer math with fixed-point scaling • Interactive chat mode: Just run CHAT with no arguments

Attached: 3 images Developer creates 'Conversational AI' that can run in 64kb of RAM on 1976 Zilog Z80 CPU-powered System — features a tiny Chatbot and a 20-Question guessing Game. The venerable Zilog Z80 CPU has been around since 1976, and it has powered everything from calculators and home computers to arcade cabinets. But the 8-bit microprocessor isn't exactly a powerful CPU compared to what we use today. That said, developer HarryR has created Z80-μLM, a working "AI" for the well-respected microprocessor. ⁉️[HarryR] confirms that it won't pass the Turing test, but it is a bit of fun. And no, the price of Z80s will not be impacted by AI.⁉️ https://github.com/HarryR/z80ai #zilog #z80 #conversational #ai #retrocomputing #engineering #media #retro #tech #news
