onepool 0.3.0

Turn the laptops in the room into one pool of ML compute. Ad-hoc, zero-config LAN clusters for training and inference on whatever hardware you have.

onepool

Turn the laptops in the room into one pool of ML compute.

onepool makes any group of computers on the same local network — Windows, Linux, or macOS; NVIDIA, AMD, integrated graphics, or plain CPUs — into a single ad-hoc cluster for machine learning. Not just inference: real distributed training over ordinary WiFi is the headline feature.

pipx install onepool          # every machine, any OS

# machine A — anyone in the room
onepool up                    # start a pool, get a session code

# machines B, C, D
onepool join amber-fox-42     # zero config, auto-discovered

# machine A
onepool train run.yaml        # fine-tune across every machine in the pool
# Ctrl-C → clean teardown. Nothing persists. No accounts. No daemons.

Why

• Existing tools don't do this. exo (archived) was inference-only and Apple-first. hivemind targets internet-scale volunteer computing. Ray and Horovod need DevOps expertise and homogeneous clusters. Nothing lets a study group pool three mismatched laptops for an evening of fine-tuning.
• Heterogeneous is the default, not the edge case. A 6GB RTX 3050 and a 4GB GTX 1650 in the same pool, each doing work proportional to what it can actually handle — measured, not assumed.
• WiFi is enough. Training uses a DiLoCo-style low-communication algorithm (many local steps, rare synchronization of small pseudo-gradients) plus LoRA adapters, so a sync round is megabytes, not gigabytes.
• Session-based by design. A pool exists while its processes run and vanishes when they stop. Disposable clusters, not infrastructure.

Status

Pre-alpha, built in the open. Roadmap:

Milestone	Scope	Status
M0	CLI skeleton, hardware probe, onepool doctor	✅ done
M1	Zero-config discovery, join/leave, live dashboard	✅ done
M2	Single-node LoRA fine-tuning path	✅ done
M3	Distributed training (DiLoCo) across mixed hardware over WiFi	✅ done
M4	Sync compression, rebalancing, first release	🔜 next
v0.2	Distributed inference	planned

Try it now

git clone https://github.com/one-pool/onepool && cd onepool
uv sync
uv run onepool doctor    # what can this machine contribute to a pool?

onepool doctor detects your GPU(s) and tells you the exact PyTorch install command for your hardware — the one genuinely fiddly step on heterogeneous machines.

Design in one paragraph

Every node runs the same process. mDNS (plus a UDP-broadcast fallback) advertises presence; a human-readable session code carries a shared secret so only invited machines join. The node that submits a job coordinates it: it benchmarks each worker on the actual model, shards data proportional to measured throughput, and runs DiLoCo — each worker takes ~100 local AdamW steps, then the pool all-reduces int8-quantized pseudo-gradients (for LoRA runs, single-digit megabytes) into an outer Nesterov-SGD step. Workers that vanish mid-round are dropped and their shard redistributed; workers that appear are folded in at the next sync. The dashboard is a local web page served by the coordinator.
