Opening a session = “buying a bid.” You stake MOR for a fixed duration; the proxy-router routes prompts to the chosen provider until the session closes (or you close it). The MOR is escrowed, not spent up-front — see Sessions: stake, close, claim before you panic about a dropping wallet balance.

Via MorpheusUI

1

Confirm wallet funding

Lower-left of MorpheusUI shows your wallet address; the Wallet tab shows MOR and ETH balances. You need at least 5 MOR for a session and a small ETH balance for gas.
2

Pick a remote model

Chat tab → Change Model → pick from the remote dropdown (anything other than “Local Model”). The dropdown lists models registered in the Diamond marketplace contract.
3

Open a session

Click Open Session. Enter a stake (minimum 5 MOR). Confirm.
4

Watch for the on-chain confirmation

A transaction will be submitted. Once confirmed, the session is open and you can prompt.
5

Close when done (or let it expire naturally)

Two paths:
  • Natural expiration — if you let the session run to its endsAt, your consumer node submits closeSession ~1 minute later (assuming it’s online) and your full share lands back in your wallet inside that one transaction.
  • Early close — click the time icon next to the model line; click X next to the session. The contract may park a slice in userStakesOnHold (1-day timelock); the rest comes back immediately. After the timelock you must call withdrawUserStakes to claim the held slice.

curl -X POST 'http://localhost:8082/blockchain/models/<modelId>/session' \
  -H 'Content-Type: application/json' \
  -H 'Authorization: Basic <base64(user:pass)>' \
  -d '{"sessionDuration": 600, "failover": false, "directPayment": false}'
Response:

Close it: 
curl -X POST 'http://localhost:8082/blockchain/sessions/<sessionId>/close' \
  -H 'Authorization: Basic <base64(user:pass)>' -d '{}'

What you should expect

  • Wallet balance drops by the staked amount the instant the open transaction is mined. The MOR is now in the Inference Contract on Base for the duration of the session.
  • Natural expiration: at endsAt, your consumer node submits closeSession ~1 minute later and the full share of your stake lands in your wallet inside that single transaction. No separate withdraw needed.
  • Early close: a slice may go to userStakesOnHold with releaseAt = startOfTheDay(closedAt) + 1 day (≈ “after the end of the next full UTC day”). The rest is returned immediately. After releaseAt, call withdrawUserStakes(yourAddress, iterations) directly on the Diamond contract — there is no HTTP route on the proxy-router.
  • The provider is paid from a separate protocol funding account, not from your stake in real time. If that funding account is empty or under-approved, every closeSession fails — yours included. The session sits “active” past endsAt until operators top it up. See Why is my MOR locked? and Sessions: stake, close, claim.
  • For a hosted read-only wallet checker that splits your MOR across the three on-chain buckets (wallet / active session / on-hold), see tech.mor.org/session.html.

Picking a good bid

There is no single right answer; consider:
  • pricePerSecond — lower is cheaper but providers compete on quality and uptime.
  • Provider reputation / stake — higher provider stake means more skin in the game.
  • TEE vs non-TEE — tee-tagged models give you cryptographic guarantees about the running software (see TEE overview).
  • Throughput / capacity — see live data at active.mor.org.
