Python SDK Phase 1

Python 3.11+ client for the DAIT chain. Includes the dait-cli command for one-off operations from a shell. Sync and asyncio APIs both supported.

Install

pip install dait-sdk

Quick tour

import os
from dait_sdk import DaitChainClient, ComputeSession

dait = DaitChainClient(
    rpc_url="https://rpc.daitchain.io",
    evm_rpc_url="https://rpc.daitchain.io",
    mnemonic=os.environ["DAIT_MNEMONIC"],
)

with ComputeSession.open(
    dait,
    model_id="qwen2.5-32b-instruct",
    max_calls=10_000,
    escrow_uDAIT=5_000_000,
) as session:
    out = session.infer(prompt="Summarize this PDF", attachments=[pdf_bytes])
    print(out.text)
    print(out.receipt.tokens_out, "tokens billed at", out.receipt.price_uDAIT)

CLI

dait-cli auction submit --model qwen2.5-32b-instruct --max-price 25
dait-cli channel open --host dait1abc... --escrow 5000000
dait-cli receipt verify ./receipt.b64
dait-cli pouw credits --address dait1xyz...
dait-cli tier register --tier node --gpu-uuid GPU-XXXX

The CLI reads $DAIT_MNEMONIC from the environment and the chain endpoint from $DAIT_RPC_URL (or ~/.dait/config.toml).

Async API

import asyncio
from dait_sdk.async_ import AsyncDaitChainClient, AsyncComputeSession

async def main():
    async with AsyncDaitChainClient(rpc_url="https://rpc.daitchain.io") as dait:
        async with AsyncComputeSession.open(dait, model_id="qwen2.5-32b-instruct") as s:
            async for chunk in s.stream(prompt="Tell me a story"):
                print(chunk.text, end="", flush=True)

asyncio.run(main())

Receipt verification

from dait_sdk import verify_receipt

next_state = verify_receipt(headers, request_bytes, response_bytes, channel_state)
# returns an updated ChannelState, or raises a typed exception

Direct chain access

from dait_sdk.cosmos import MsgRegisterTier

tx = dait.tx.broadcast([
    MsgRegisterTier(signer=dait.address, tier_id=3),  # Node
])
print(tx.tx_hash)

Provider mode (dait-host)

The provider daemon at github.com/dait-chain/dait-host shares the same dait_sdk primitives. If you are running a host you typically use dait-host (the daemon) rather than the SDK directly. See run a compute host.

Status

Phase 0 scaffold. Cryptography primitives stubbed; public publish to PyPI aligns with Phase 1 alpha.
