☕ Support Project Maya - buy me a coffee

Models this size usually need a datacenter. Maya runs GLM-5.3-Flash (zai-org, MIT license) on the hardware you already have: 321 B parameters, about 18 B active per token, and a context of up to 1 M tokens. Its engine is built for this one model. It keeps the experts your conversation uses most on the GPU, the next ones in RAM and the rest on your NVMe SSD, and moves them as you chat. It measures your GPUs, CPU, RAM and SSD and tunes itself to them. Nothing leaves your machine.

• Fast: up to 118 tokens/s on four RTX 4090s, 30+ on a single RTX 5090. Real numbers from real users below.
• Close to the original: Maya's own quants keep 97.7-99.2% of the FP8 model's zero-shot accuracy.
• Plugs into your tools: OpenAI- and Anthropic-compatible API with tool calls, ready for coding agents.
• Several requests at once: up to 8 answered together - for agents that run several sessions, or several people on one PC.
• Everything in the box: a chat and a live monitor in the browser, pictures, thinking levels, a one-command setup.

Project Maya's own quants of GLM-5.3-Flash, made from Z.ai's FP8 release with statistics from the FP8 model. Each keeps the model's MTP block, which drafts tokens ahead.

The setup asks which one to download and recommends one for your PC. How they're made and measured: MAYA-S, MAYA-S24, MAYA-M, MAYA-L. On Hugging Face.

Real machines, real numbers, most of them measured with ./maya.sh --bench. A token is about ¾ of a word.

Prefill is an 8K-token prompt. The speed holds as a conversation grows, and the first answers after a start are the slowest while the caches fill with what you use. Share yours: --bench, then --report, in a GitHub issue.

Several requests at once (--parallel) add up: on one GPU a token of each goes through the model together, so the dense weights are read once for all of them. In tokens per second for all of them together, against the same questions one after another: x1.41 for two and x1.35 for four on a V100 that streams most of Maya-S's experts from RAM, x1.67 for two and x2.02 for four on a Strix Halo that holds every expert in GPU memory. The more of the model VRAM holds, the more it gains (how).

The setup checks all of this, prints the exact command for anything missing, and installs nothing system-wide.

git clone https://github.com/mw00/project-maya.git && cd project-maya
./setup.sh

Answer a few questions (Enter takes the recommended choice). The setup shows every download before it starts it, builds everything once (20-40 minutes plus the download) and starts the model. Then open http://127.0.0.1:8080. Ctrl+C stops it, and ./setup.sh starts it again right away.

• Windows: START-MAYA.bat instead of ./setup.sh - see docs/WINDOWS.md.
• AMD: docs/AMD_MAYA.md.
• Updating: the dashboard's About > Update, or git pull then ./setup.sh. The model isn't downloaded again.
• Every option (GPUs, context, a model folder you already have, remote access, ...): docs/SETUP.md.

The start takes a few minutes: the engine pins most of the free RAM (all but about 6 GB) for its expert tier, so other programs get little RAM while Maya runs.

• In the browser: chat (kept in your browser, per-chat instructions, edit and regenerate, HTML previews), a live Monitor of the model and your hardware, and a context size you can change in Settings.
• Your apps and coding agents: an OpenAI-compatible API at http://127.0.0.1:8080/v1, and Anthropic's at http://127.0.0.1:8080/v1/messages (Claude Code: ANTHROPIC_BASE_URL=http://127.0.0.1:8080). Tool calls are streamed as the model writes them. A web page served from another address can call it too once you allow its address ("cors_origins", docs/SETUP.md).
• Thinking: Off, Low, High (the default) or Max, in Settings or per request.
• Pictures: attach one in the chat, or send image parts through either API.
• From another device: ./maya.sh --setup --host 0.0.0.0 --api-key <secret>. Always set a key.
• Tuning: ./maya.sh --calibrate tunes the engine to your hardware in 10-15 minutes. Every setting: docs/SETTINGS.md.
• Several requests at once: ./maya.sh --parallel 4 (Windows: START-MAYA.bat --parallel 4; up to 8) keeps it in the config, and the dashboard shows how many answers are being written. Each extra request keeps its own context in VRAM, so a few fewer experts fit there (how).
• Faster answers with a DFlash2 drafter: ./maya.sh --setup --draft dflash2 (NVIDIA RTX 30 / A100 and newer) downloads a small drafter that drafts up to 7 tokens a round and gives the same answers - Maya-L +44% on nine GPUs and +12% on two (against the MTP block), +19% on one RTX 3090 (how). A speed calibration then measures it on your PC and keeps it only where it is faster. The drafter's license is non-commercial (CC BY-NC-ND 4.0).

Run ./maya.sh --report (Windows: START-MAYA.bat --report) right after a slow answer or an error, and attach the maya-report.txt it writes to a GitHub issue. It holds your hardware, your setup and the engine's speed lines; nothing is sent anywhere by itself. The engine's own log is maya-<model>.log in the Maya folder.

• "nvcc ... cannot build for these GPUs": Volta needs CUDA 12.x, Blackwell 12.8 or newer. The setup takes the newest installed toolkit that fits.
• "unsupported GNU version": ./maya.sh --setup --host-compiler g++-12 (install g++-12 first).
• Slow, with the SSD busy all the time: not enough free RAM for the experts. Close programs or add RAM.
• The download stopped: run ./maya.sh again; it continues where it stopped.
• Port 8080 is in use: Maya is already running, or --port 8081 starts another one.
