Susana Ferreira 48f07e6e13 feat: add user AI spend endpoint (#26978)
## Description

Adds the `GET /api/v2/users/{user}/ai/spend` endpoint returning the
user's current AI spend, effective budget, and period bounds.

## Changes

- Add `userAISpendStatus` handler under the same feature/experiment gate
as `/api/v2/users/{user}/ai/budget`.
- Add `codersdk.UserAIBudgetSummary` (embedded into `UserAISpendStatus`)
and a `UserAISpendStatus` client method.
- Move `LimitSource` from `coderd/aibridge/budget` to `codersdk` so the
type is shared across endpoints.

Closes https://linear.app/codercom/issue/AIGOV-472

Paweł BanaszewskiandDanny Kopping ccba3969ab feat: add ai-gateway start command (#26605)
> AI Tools were used to produce this PR

This PR adds `coder ai-gateway start` command that runs the AI Gateway
as an independent process.

- Standalone process doesn't have access to DB. Uses DRPC services under
`/api/v2/ai-gateway/serve`for auth, recording and provider
initialization.
- It only handles LLM traffic, other endpoints (eg. `/sessions`) are
only available though `coderd`.
- The standalone gateway reuses applicable flags from AI Gateway
deployment options. Provider-seeding and coderd-only options are
excluded.
- Only added to fat build, the slim build stub rejects the command.

Some wiring used by this new command is added.

**`NewWebsocketDialer`** - implements the standalone gateway's
connection to coderd's `/api/v2/ai-gateway/serve` endpoint. It upgrades
to a WebSocket, multiplexes with yamux, and wires all DRPC services.

**`AIGatewayDataPlaneMiddleware`** - extracts the per-request middleware
chain (concurrency limiting, rate limiting, BYOK gating) into a shared
function used by both the embedded route and the standalone gateway.

**`RootCmd.ResolveClientConnection`** - resolve the deployment URL and
builds an HTTP transport without requiring a session token. Used in
`ai-gateway start`command as it authenticates using different credential
type.

Susana Ferreira 5cae613af1 docs: rename AI Bridge to AI Gateway in swagger summaries (#26704)
Update `@Summary` and `@ID` annotations in
`enterprise/coderd/aibridge.go` from "AI Bridge" to "AI Gateway".
Regenerate swagger docs and API reference via `make gen`.

This was missed in the original API route aliases PR (#26475) which
renamed `@Tags` but not `@Summary` or `@ID` values. The `@ID` must also
change because a test (`assertConsistencyBetweenRouteIDAndSummary`)
enforces that the ID is the kebab-case form of the summary.

Susana Ferreira 970bd73691 feat: add /api/v2/ai-gateway API route aliases (#26475)
## Description

Registers `/api/v2/ai-gateway/*` as the new API path for AI Gateway, replacing `/api/v2/aibridge/*`. Both prefixes share the same route builder (`aiBridgeRoutes`) backed by a single in-memory handler, so existing `/aibridge` endpoints continue to work. New endpoints must be registered on the enterprise API handler under `/api/v2/ai-gateway` only.

Swagger annotations now point to `/api/v2/ai-gateway` paths with a backward-compatibility note referencing `/aibridge`. The legacy `/aibridge` routes are skipped in the swagger documentation test.

## Changes

- Store one raw handler (`aiGatewayHandler`) instead of two prefix-stripped handlers
- Register `/ai-gateway` and `/ai-gateway/proxy` route aliases alongside legacy `/aibridge` routes
- Move `/aibridge/keys` to `/ai-gateway/keys`
- Update in-process transport to use `/api/v2/ai-gateway` prefix
- Update SDK client URLs and proxy forwarding URL
- Swap `@Router` and `@Tags` annotations from `aibridge`/`AI Bridge` to `ai-gateway`/`AI Gateway`
- Rename user-facing error messages from "AI Bridge" to "AI Gateway"
- Define consts for route prefixes (`AIGatewayRootPath`, `AIBridgeRootPath`)
- Update tests and comments to use new paths

Note: the following will be addressed in follow-up PRs:
- Frontend API URLs
- Frontend routes and redirects
- Dogfood main.tf updates
- Hand-written documentation URL updates
- aibridge internal comments and nits
- Scale tests path updates

Danny Kopping a1330e3a8c refactor: rename Ai* database identifiers to AI* (AIGOV-369) (#26327)
Adds `ai` to sqlc's `gen.go.initialisms` in `coderd/database/sqlc.yaml`
so the generated DB code follows Go's initialism convention. Adds the
matching `ai` -> `AI` case to the dbgen PascalCase helper
(`scripts/dbgen/main.go`) so the corresponding `dbmem` / mock
identifiers stay in sync. `make gen` regenerates the rest; hand-written
call sites that consume DB-generated identifiers
(`enterprise/audit/table.go`, `coderd/database/modelmethods.go`,
`enterprise/coderd/aigatewaykeys.go`, `coderd/database/dbauthz/*`, etc.)
are updated to match.

Scope is deliberately limited to the database layer:

- `coderd/rbac/*` (resource and scope generators) is untouched —
`ResourceAi*` / `ScopeAi*` constants stay on main's casing.
- `codersdk/*` (Go SDK) is untouched — `codersdk.ResourceAi*` /
`codersdk.APIKeyScopeAi*` constants stay on main's casing, so external
Go SDK consumers see no source-level break.
- `Aibridge*` identifiers (one SQL token `aibridge`, not `ai_bridge`)
are out of scope.

On-the-wire values are unchanged: enum strings, RBAC resource type
strings, API key scope strings, and JSON tags all stay the same. The
HTTP/JSON surface is unaffected.

Danny Kopping 4a07f61c50 refactor!: remove interceptions API, request logs view, and associated code (#26213)
## Summary

Removes the deprecated `/api/v2/aibridge/interceptions` endpoint and the
Request Logs frontend page, both replaced by the session-based view.

Closes https://linear.app/codercom/issue/AIGOV-266
Closes https://linear.app/codercom/issue/AIGOV-324

## Changes

### Backend
- Remove `GET /api/v2/aibridge/interceptions` HTTP handler and route
- Remove SDK types and client method (`AIBridgeInterception`,
`AIBridgeTokenUsage`, `AIBridgeUserPrompt`, `AIBridgeToolUsage`,
`AIBridgeListInterceptionsResponse`, `AIBridgeListInterceptionsFilter`)
- Remove SQL queries `CountAIBridgeInterceptions` and
`ListAIBridgeInterceptions`
- Remove `searchquery.AIBridgeInterceptions` parser
- Remove dbauthz wrappers, in-memory implementations, metrics, and mocks
for the interceptions list queries
- Remove the `coder aibridge interceptions list` CLI command and golden
files
- Regenerate API docs, swagger, mocks, and metrics

The `/models`, `/clients`, and `/sessions` endpoints stay; the sessions
list page still consumes all three.

### Frontend
- Delete the entire `RequestLogsPage/` directory (page, view, row,
filter, stories, tests)
- Remove the `/aibridge/request-logs` route and its lazy import
- Remove the `getAIBridgeInterceptions` API method,
`paginatedInterceptions` query, and mock interception entities
- `git mv` the shared filter and icon components used by the sessions
pages:
- `RequestLogsPage/RequestLogsFilter/{Client,Model,Provider}Filter.tsx`
→ `AIBridgePage/filters/`
- `RequestLogsPage/icons/AIBridge{Client,Model,Provider}Icon.tsx` →
`AIBridgePage/icons/`
- Drop the `getProviderIconName` hack and the duplicate `anthropic-neue`
icon case now that the FIXME no longer applies

## Commits

1. `refactor: remove interceptions API and request logs view` — the bulk
removal, with explicit renames for the shared filter/icon files.
2. `refactor(site/src/pages/AIBridgePage): drop getProviderIconName
hack` — cleanup of the FIXME that depended on RequestLogsPage existing.

Yevhenii Shcherbina 360611ea15 feat: audit user AI budget override mutations (#25745)
Relates to
https://linear.app/codercom/issue/AIGOV-285/add-user-budget-overrides-table-and-crud-api

Adds audit-log support for `user_ai_budget_override` mutations. Without
it, an admin could quietly change a user's per-user spend cap (e.g. from
`$500` to `$50`), reassign it to a different group, or delete it
entirely with no record of who did it.

Both write (`create-or-update`) and delete actions now generate audit
log entries. Unlike group AI budgets, which only track `spend_limit`,
overrides also track `group_name`: an override can be reassigned to a
different attributed group, so that change needs to show up in the diff.
The raw `spend_limit_micros`, IDs, and timestamps are ignored in favor
of the human-readable `spend_limit` and `group_name`.

Depends on #25439.

Yevhenii Shcherbina 1a91d31793 feat: add user AI budget override endpoints (#25439)
Implements https://linear.app/codercom/issue/AIGOV-285
Follow the structure established in
https://github.com/coder/coder/pull/25203

## Summary

Adds the `user_ai_budget_overrides` table and CRUD API at
`/api/v2/users/{user}/ai/budget`. An override sets a custom per-user
spend cap that supersedes group-budget resolution, attributing spend to
a specific group.

## Schema

```sql
CREATE TABLE user_ai_budget_overrides (
    user_id            UUID        PRIMARY KEY REFERENCES users(id) ON DELETE CASCADE,
    group_id           UUID        NOT NULL REFERENCES groups(id) ON DELETE CASCADE,
    spend_limit_micros BIGINT      NOT NULL CHECK (spend_limit_micros >= 0),
    created_at         TIMESTAMPTZ NOT NULL DEFAULT NOW(),
    updated_at         TIMESTAMPTZ NOT NULL DEFAULT NOW()
);
```

## Membership lifecycle

The membership invariant — a user must be a member of the attributed
group, including when that group is "Everyone" — would naturally be
expressed as a composite FK on `(user_id, group_id) →
group_members_expanded(user_id, group_id)`. PostgreSQL doesn't allow
foreign keys to reference views, so enforcement is split across two
mechanisms:

- **Write-time check.** A CHECK constraint on the table
(`user_ai_budget_overrides_must_be_group_member`) calls a `STABLE`
function `is_group_member(user_id, group_id)` that queries
`group_members_expanded`. The view surfaces both regular group
memberships and the implicit "Everyone" group memberships from
`organization_members`. Any INSERT or UPDATE that violates the predicate
is rejected with a Postgres `check_violation`, which the handler maps to
a 400. `is_group_member` is defined as a general predicate, reusable by
any future table that needs the same check.

- **Cascade on removal.** Two `BEFORE DELETE` triggers handle membership
loss:
- `trigger_delete_user_ai_budget_overrides_on_group_member_delete` on
`group_members` — covers regular group removals (admin action, OIDC
sync).
- `trigger_delete_user_ai_budget_overrides_on_org_member_delete` on
`organization_members` — covers the "Everyone" group, whose membership
lives in `organization_members`.

The single-column FKs on `users(id)` and `groups(id)` remain to cascade
on user or group deletion (those paths don't pass through
`group_members`).

## Authorization

The dbauthz layer gates each operation against the `User` and (for
writes) `Group` resources:

| Operation | User resource  | Group resource |
|-----------|----------------|----------------|
| `GET`     | `ActionRead`   | —              |
| `PUT`     | `ActionUpdate` | `ActionUpdate` |
| `DELETE`  | `ActionUpdate` | `ActionUpdate` |

For `DELETE`, the dbauthz layer fetches the existing override first to
learn the attributed `group_id`, then runs both checks.

### Role matrix

| Role         | GET | PUT | DELETE |
|--------------|-----|-----|--------|
| Owner        |    |    |       |
| UserAdmin    |    |    |       |
| OrgAdmin     |    |    |       |
| OrgUserAdmin |    |    |       |

Relates to
https://linear.app/codercom/issue/AIGOV-284/add-group-budgets-table-and-crud-api

Adds audit-log support for `group_ai_budget` mutations. Without it, an
admin could silently lower a spend limit from `$500` to `$50` or delete
a budget entirely, with no record of who performed the action.

Both write (`create-or-update`) and delete actions now produce audit log
entries, including before/after diffs for `spend_limit_micros`.

Depends on #25203.

Yevhenii Shcherbina 238968cfa0 feat: add per-group AI budget table and endpoints (#25203)
Closes
https://linear.app/codercom/issue/AIGOV-284/add-group-budgets-table-and-crud-api

## Summary

Adds the `group_ai_budgets` table and the following endpoints:

- `GET /api/v2/groups/{group}/ai/budget`
- `PUT /api/v2/groups/{group}/ai/budget`
- `DELETE /api/v2/groups/{group}/ai/budget`

Each group may have at most one budget row. If no row exists, no budget
is enforced.

### Feature gate
  
Added `RequireFeatureMW(FeatureAIBridge)` on the `/ai/budget` sub-route.

## RBAC

Authorization reuses `rbac.ResourceGroup` with the existing
`.InOrganization(...).WithID(...)` scoping model.

The `dbauthz` wrappers load the parent `groups` row and authorize
against it.

No new resource type is introduced. As a result, anyone with
`group:update` permissions (Owner, OrgAdmin, or UserAdmin within the
organization) can manage AI budgets for that group.

## Read access for group members

`database.Group.RBACObject()` grants `policy.ActionRead` to all members
of the group through the group ACL:

```go
func (g Group) RBACObject() rbac.Object {
	return rbac.ResourceGroup.WithID(g.ID).
		InOrg(g.OrganizationID).
		// Group members can read the group.
		WithGroupACL(map[string][]policy.Action{
			g.ID.String(): {
				policy.ActionRead,
			},
		})
}
```

Because the `GET` endpoint authorizes against the same loaded `Group`
object, any group member can call:

```text
GET /api/v2/groups/{group}/ai/budget
```

`PUT` and `DELETE` remain admin-only. The group ACL grants only
`ActionRead`, so write operations continue to require role-based
`group:update` permissions.

## Alternative considered

A dedicated `rbac.ResourceGroupAiBudget` resource would allow budget
management to be separated from general group administration.

We decided not to add that complexity for now.

Danny Kopping dba9f68b11 chore!: remove members' ability to read their own interceptions; rationalize RBAC requirements (#23320)
_Disclaimer:_ _produced_ _by_ _Claude_ _Opus_ _4\.6,_ _reviewed_ _by_ _me._

**This is a breaking change.** Users who are not have `owner` or sitewide `auditor` roles will no longer be able to view interceptions.  
Regular users should not need to view this information; in fact, it could be used by a malicious insider to see what information we track and don't track to exfiltrate data or perform actions unobserved.

---

Changed authorization for AI Bridge interception-related operations from system-level permissions to resource-specific permissions. The following functions now authorize against `rbac.ResourceAibridgeInterception` instead of `rbac.ResourceSystem`:

- `ListAIBridgeTokenUsagesByInterceptionIDs`
- `ListAIBridgeToolUsagesByInterceptionIDs`
- `ListAIBridgeUserPromptsByInterceptionIDs`

Updated RBAC roles to grant AI Bridge interception permissions:

- **User/Member roles**: Can create and update AI Bridge interceptions but cannot read them back
- **Service accounts**: Same create/update permissions without read access
- **Owners/Auditors**: Retain full read access to all interceptions

Removed system-level authorization bypass in `populatedAndConvertAIBridgeInterceptions` function, allowing proper resource-level authorization checks.

Updated tests to reflect the new permission model where members cannot view AI Bridge interceptions, even their own, while owners and auditors maintain full visibility.

_Disclaimer:_ _initially_ _produced_ _by_ _Claude_ _Opus_ _4\.6,_ _heavily_ _modified_ _and_ _reviewed_ _by_ _me._

Closes https://github.com/coder/internal/issues/1360

Adds a new `/api/v2/aibridge/sessions` API which returns "sessions".

Sessions, as defined in the [RFC](https://www.notion.so/coderhq/AI-Bridge-Sessions-Threads-2ccd579be59280f28021d3baf7472fbe?source=copy_link), are a set of interceptions logically grouped by a session key issued by the client.  
The API design for this endpoint was done in [this doc](https://github.com/coder/internal/issues/1360).

If the client has not provided a session ID, we will revert to the thread root ID, and if that's not present we use the interception's own ID (i.e. a session of a single interception - which is effectively what we show currently in our `/api/v2/aibridge/interceptions` API).

The SQL query looks gnarly but it's relatively simple, and seems to perform well (~200ms) even when I import dogfood's `aibridge_*` tables into my workspace. If we need to improve performance on this later we can investigate materialized views, perhaps, but for now I don't think it's warranted.

Kacper Sawicki 6f86f67754 feat(coderd): add overload protection with rate limiting and concurrency control (#21161)
## Summary

This adds configurable overload protection to the AI Bridge daemon to
prevent the server from being overwhelmed during periods of high load.

Partially addresses coder/internal#1153 (rate limits and concurrency
control; circuit breakers are deferred to a follow-up).

## New Configuration Options

| Option | Environment Variable | Description | Default |
|--------|---------------------|-------------|---------|
| `--aibridge-max-concurrency` | `CODER_AIBRIDGE_MAX_CONCURRENCY` |
Maximum number of concurrent AI Bridge requests. Set to 0 to disable
(unlimited). | `0` |
| `--aibridge-rate-limit` | `CODER_AIBRIDGE_RATE_LIMIT` | Maximum number
of AI Bridge requests per second. Set to 0 to disable rate limiting. |
`0` |

## Behavior

When limits are exceeded:
- **Concurrency limit**: Returns HTTP `503 Service Unavailable` with
message "AI Bridge is currently at capacity. Please try again later."
- **Rate limit**: Returns HTTP `429 Too Many Requests` with
`Retry-After` header.

Both protections are optional and disabled by default (0 values).

## Implementation

The overload protection is implemented as reusable middleware in
`coderd/httpmw/ratelimit.go`:

1. **`RateLimitByAuthToken`**: Per-user rate limiting that uses
`APITokenFromRequest` to extract the authentication token, with fallback
to `X-Api-Key` header for AI provider compatibility (e.g., Anthropic).
Falls back to IP-based rate limiting if no token is present. Includes
`Retry-After` header for backpressure signaling.
2. **`ConcurrencyLimit`**: Uses an atomic counter to track in-flight
requests and reject when at capacity.

The middleware is applied in `enterprise/coderd/aibridge.go` via
`r.Group` in the following order:
1. Concurrency check (faster rejection for load shedding)
2. Rate limit check

**Note**: Rate limiting currently applies to all AI Bridge requests,
including pass-through requests. Ideally only actual interceptions
should count, but this would require changes in the aibridge library.

## Testing

Added comprehensive tests for:
- Rate limiting by auth token (Bearer token, X-Api-Key, no token
fallback to IP)
- Different tokens not rate limited against each other
- Disabled when limit is zero
- Retry-After header is set on 429 responses
- Concurrency limiting (allows within limit, rejects over limit,
disabled when zero)

Danny Kopping ff532d9bf3 chore: handle deprecated aibridge experimental routes (#20565)
In v2.28 we're [removing the aibridge
experiment](https://github.com/coder/coder/pull/20544).

We need to handle `/api/experimental/aibridge/*` until Beta (next
release).

Jake Howell d455f6ea2b fix: rename total to count in AIBridgeListInterceptionsResponse (#20410)
Thanks to the great work in #20393, we’ve successfully introduced
offset-based pagination for this endpoint. However, the frontend expects
a `count` field in the response rather than `total`. This PR updates the
response payload to rename the returned key to `count` for consistency
with frontend expectations and existing API patterns.

This is necessary to unblock the work in #20331

Dean Sheather 69c2c40512 chore: add user details to aibridge interception list endpoint (#20397)
- Adds FK from `aibridge_interceptions.initiator_id` to `users.id`
- This is enforced by deleting any rows that don't have any users. Since
this is an experimental feature AND coder never deletes user rows I
think this is acceptable.
- Adds `name` as a property on `codersdk.MinimalUser`
- This matches the `visible_users` view in the database. I'm unsure why
`name` wasn't already included given that `username` is.
- Adds a new `initiator` field to `codersdk.AIBridgeInterception` which
contains `codersdk.MinimalUser` (ID, username, name, avatar URL)
- Removes `initiator_id` from `codersdk.AIBridgeInterception`
    - Should be fine since we're still in early access

Dean Sheather ea261a1f7c chore: add offset-based pagination support to aibridge list endpoint (#20393)
Necessary for the frontend to be able to paginate easily. Cursor
pagination is good for fetching all events, but doesn't play very well
when a pagination component gets involved.

Adds support for `?offset=x` to the existing endpoint. The cursor-based
pagination (`?after_id=x`) is still supported. The two pagination modes
are mutually exclusive, and are documented as such. If both are
supplied, the request will be rejected.

Also adds a `total` property to the response that contains the full
count of items matching the filter. We already have indices in place so
I don't think this will impact performance (or we can revisit it before
GA).
