Cycle 2 Agent Memory Challenge Participation Guide

Agent Memory Challenge is the second public evaluation cycle of Agent Memory Leaderboard. It is open to researchers, open-source maintainers, and commercial product teams worldwide. Participants provide Add and Search; the platform runs Answer, Eval, result review, and leaderboard publication.

Cycle 2 at a glance

Participation is free, with no team-size requirement. Participants cover the cost of their own APIs, databases, bandwidth, and compute; the platform covers unified Answer, Eval, and evaluation orchestration.

Evaluation types

Textual, Coding, and Multimodal Memory

Step 1: Choose an evaluation type

The evaluation type determines the tasks your system receives; the participant division determines where the result is listed. These are two independent dimensions.

Evaluation typeWhat it evaluatesAvailable divisionsCycle 2 schedule
Textual MemoryLong conversations, cross-session history, facts, multi-hop relations, temporal events, personalization, rules, memory governance, and Streaming memory.Open-source Methods / Commercial ProductsMaterials close October 31 at 23:59
Coding MemoryRetrieving, filtering, and reusing engineering experience from the same repository under relevant and noisy conditions.Open-source Methods / Commercial ProductsMaterials close October 31 at 23:59
Multimodal MemoryWriting, retrieving, and using evidence from text-and-image memories through ordered text and Base64 image content arrays.Open-source Methods / Commercial ProductsMaterials close October 31 at 23:59

Step 2: Deploy and submit your APIs

In Cycle 2, every participant division must host stable Add / Search APIs. An Eval Key is issued after the submitted online endpoints and materials pass review.

Open-source Methods · API

Host your own Add / Search APIs

Submit fixed Add / Search endpoints, authentication and operational details. A public repository supports openness and attribution review but cannot replace deployed endpoints.

Commercial · API

Provide a stable product API

Submit a fixed product version, Add / Search endpoints, authentication, and capacity details. Internal implementation may remain closed; an Eval Key is issued after approval and results enter the Commercial Products board.

Unified integration requirement

Open-source and commercial entries integrate through participant-hosted Add/Search APIs. Cycle 2 does not accept repository-only or Docker-only submissions for AML deployment. Open-source materials remain part of openness and attribution review.

Step 3: Prepare your submission

Freeze a clear evaluation version before applying. Once a formal Full evaluation is accepted, the version may not be replaced or withdrawn because of an unfavorable result.

For everyone

Common materials

System name and version, contact details, organization or team, intended evaluation type, method or product description, information approved for public display, and complete submission notes.

Open-source Methods

API and openness materials

Deployed Add/Search endpoints, authentication and capacity declarations, plus a public repository, fixed commit, attribution of prior work, and method changes.

Commercial Products

API and operations

Fixed product version, Add / Search APIs, authentication, a dedicated evaluation credential, capacity, timeout, and rate-limit details.

From request to leaderboard

1

Submit a request

Choose an evaluation type, participant division, and submission route, then provide a fixed system version and complete materials.

2

Complete integration

The platform reviews the live API and submitted materials, then issues an Eval Key. AML does not deploy participant systems.

3

Run Smoke and Full

Validate Add / Search, authentication, and the end-to-end path before the formal Cycle 2 Full evaluation.

4

Review and publish

The platform reviews the version, results, and compliance status before publishing the entry to its corresponding public board.

Eval Key and Memory System Key

These credentials are issued by different parties and serve different purposes. Never place either credential in a public repository, URL, screenshot, email body, or group chat.

CredentialProvided byPurposeWho needs it
Eval Key / Leaderboard KeyAgent Memory LeaderboardVerifies participant access, starts evaluations, and unlocks private results.Open-source and commercial participants whose self-hosted Add / Search APIs pass review.
Memory System KeyParticipantAllows the platform to call the participant's Add / Search APIs.Required when the submitted API uses authentication; not required for an unauthenticated endpoint.

Rewards

The second Agent Memory Challenge provides a total prize pool of US$22,000 across the Textual, Coding, and Multimodal tracks. Prizes are available only to eligible Open-source Methods teams that pass review; Commercial Products entries are not eligible.

First Prize

1 winner per track

≈ USD 3,000. The Textual, Coding, and Multimodal tracks are judged separately.

Second and Third Prizes

5 winners per track

Second Prize: 2 winners, ≈ USD 1,200 each. Third Prize: 3 winners, ≈ USD 450 each.

Best Technical Innovation

1 winner per track

≈ USD 750. The total prize pool across all three tracks is US$22,000.

What counts as a valid submission?

Complete materials

Participant identity, system version, and all required materials are complete, truthful, and verifiable.

Smoke passes

Add / Search, authentication, and the end-to-end path follow the current integration contract.

Full completes

The formal evaluation and required tasks complete successfully without missing or duplicated results.

Version matches

The code, image, or API used for the formal evaluation matches the declared version.

Review passes

The version, results, and compliance status pass organizer review before the submission is considered valid.

Core participation requirements

1

Return memory evidence

Search must not generate final answers or disguise answers as memory records.

2

Preserve sample isolation

Do not share or retrieve evaluation memories across user IDs, tasks, samples, or teams.

3

Disclose sources and changes

When reusing a paper, repository, or codebase, identify the original authors, technical report, and every method change.

4

Do not manipulate evaluation

Hard-coding, data leakage, prompt injection, live human answering, result manipulation, and leaderboard abuse are prohibited.
