Colleagues keep their existing +upstream LiteLLM key and model name and change only their gateway base URL. They +need no plugin or client-side memory tools. Choosing the pilot URL opts them into +the pilot; returning to the original URL stops using and collecting pilot memory. + +Every preparation and answer call uses that caller's upstream key. The upstream +gateway continues to enforce its model permissions, budgets, rate limits, and +guardrails. The pilot checks the key against the upstream model catalog, then +registers its hash as a local virtual key so LiteLLM's normal authentication and +memory authorization still apply. No upstream key or provider credential is +configured on Render. The administrator credential belongs only to this pilot. + +The forwarding pilot isolates memories by virtual key. Upstream management APIs +may deny ordinary keys access to user/team/org details, so the pilot does not +infer those identities from client metadata. Install the feature directly in an +organization's gateway to use its existing user/team/project/org policies. +Never connect this pilot to an older gateway's production database. + +## Create the service + +1. Create a separate Render Postgres 16 database in the same region as the web + service. Restrict public database access; use its internal connection URL. +2. Create a Python web service from this repository and the Memory V2 branch. + A Standard service and the smallest paid Postgres plan are sufficient starting + points for a small pilot. They incur Render hosting charges. +3. Set the build command to `bash deploy/memory-pilot/build.sh`, the start command + to `bash deploy/memory-pilot/start.sh`, and the health path to + `/health/readiness`. The build includes the dashboard from this branch. +4. Set these environment variables in Render: + + | Variable | Value | + | --- | --- | + | `DATABASE_URL` | The new database's internal connection URL | + | `UPSTREAM_LITELLM_BASE_URL` | Your original gateway URL, without `/v1` | + | `LITELLM_MASTER_KEY` | A new random `sk-` administrator key | + | `LITELLM_SALT_KEY` | A separate random encryption secret; preserve it across deploys | + | `PYTHON_VERSION` | `3.12.14` | + | `NODE_VERSION` | `24.19.0` | + | `NEXT_TELEMETRY_DISABLED` | `1` | + | `PORT` | `4000` | + +5. After deployment, open `/ui/memory`, sign in as `admin` using the pilot's master + key, and save a policy for **Whole gateway**, **Enabled automatically**, + **Private to each virtual key**. This policy persists across restarts. Memory + stays disabled until an administrator enables it. + +Equivalent activation through the API, with secrets supplied in shell variables: + +```bash +curl --fail-with-body "$PILOT_URL/v2/memory/policies" \ + -H "Authorization: Bearer $PILOT_ADMIN_KEY" \ + -H 'Content-Type: application/json' \ + -X PUT \ + -d '{"target_type":"gateway","target_id":"*","activation":"automatic","scope":"key"}' +``` + +Administrators can instead require opt-in, disable a particular registered key, +or disable the whole gateway. Under an opt-in policy, callers set their preference +with `PUT /v2/memory/preference` and `{"enabled":true}` using their own key. + +## Try it + +Set an OpenAI-compatible client's base URL to `https://YOUR-SERVICE.onrender.com/v1`. +For Claude Code, set `ANTHROPIC_BASE_URL` to `https://YOUR-SERVICE.onrender.com`. +Retain the same gateway key and model setting. + +In one conversation, say “Remember that my demo project is Cobalt Heron and its +staging port is 8347.” In a **new conversation**, ask “What is my demo project and +its staging port?” Check actual saved entries with `GET /v2/memory/entries` using +the same key. An unrelated key must not see them. Administrators can inspect, +correct, or delete entries in Memory; callers can use the self-service API. + +## Behavior and limits + +- Supported surfaces: Chat Completions, Responses, and Anthropic Messages, + including their native streaming responses and client tool continuation. +- The selected model must support function calling. Memory preparation adds up + to three billed model calls before the visible answer, with a 60-second bound. + It uses the original conversation, so long coding sessions can add substantial + prompt-token usage and latency. Existing upstream quotas apply to these calls. +- Preparation stores durable facts supported by the conversation, then searches + and reads relevant entries. Search is bounded keyword matching in Postgres. + There is no vector database, extraction model, scheduler, or nightly process. +- Stored references are untrusted data. They cannot grant API permissions or + change the namespace derived from authentication. Current user corrections + take precedence. Replacements require the current revision. +- Memory/model preparation errors fail the request rather than silently claiming + successful memory. Administrators can disable memory to restore ordinary calls. +- Switching away or disabling memory stops automatic use; it does not delete + existing entries. Delete memories explicitly through Memory or the API. +- Shared upstream keys share a pilot namespace. Give each person a distinct key + when their memories must be private from each other. +- Other API surfaces are outside this forwarding pilot. Use the original gateway + for embeddings, images, realtime, batches, and administration. diff --git a/deploy/memory-pilot/build.sh b/deploy/memory-pilot/build.sh new file mode 100755 index
