Rebranding Migration

On this page

AI Bridge has been renamed to AI Gateway. This is a cosmetic rebrand to make the feature easier to understand. It changes user-visible names, configuration options, the canonical HTTP API path, and the Prometheus metric names.

Note

Deprecated aliases remain available for gateway and proxy controls. Provider configuration through environment variables, flags, and YAML has been removed under both names; refer to Provider configuration.

Adopt the ai_gateway names for gateway and proxy settings so your configuration matches the current documentation.

Important

New settings added in every area except the database (configuration options, environment variables, CLI flags, and API paths) will use only the new ai_gateway name, with no aibridge alias.

At a glance

Area	Old name	New (canonical) name	Old name still works?
Environment variables	`CODER_AIBRIDGE_*`	`CODER_AI_GATEWAY_*`	Yes, except provider setup
CLI flags	`--aibridge-*`	`--ai-gateway-*`	Yes, except provider setup
YAML config group	`aibridge:` / `aibridgeproxy:`	`ai_gateway:` / `ai_gateway_proxy:`	Yes, except provider setup
HTTP API	`/api/v2/aibridge`	`/api/v2/ai-gateway`	Yes (legacy route retained)
Prometheus metrics	`coder_aibridged_` / `coder_aibridgeproxyd_`	`coder_ai_gateway_` / `coder_ai_gateway_proxy_`	Yes (both emitted, old deprecated)
Database	(no change)	(no change)	n/a

What did not change

No database changes. Table and column names (for example, aibridge_interceptions) are unchanged. No migration runs and no data is rewritten on upgrade.
Gateway and proxy settings. Renaming options for logging, retention, or listener addresses does not change their behavior or defaults.
Internal/library references. Some internal package names, log fields, and library identifiers still use the aibridge name. These are not part of the supported configuration surface and do not affect operators.

Configuration (env vars, flags, YAML)

The aliases listed below apply only to gateway and proxy controls, not provider setup.

If both a previous name and a new name are set for the same setting, set only one (prefer the new name).

Naming rules

The rename is a mechanical substitution:

Environment variables: CODER_AIBRIDGE_ becomes CODER_AI_GATEWAY_.
CLI flags: --aibridge- becomes --ai-gateway-.
YAML: only the top-level group key changes (aibridge: becomes ai_gateway:, aibridgeproxy: becomes ai_gateway_proxy:). The keys nested under the group are unchanged.

YAML example

Before:

aibridge:
  enabled: true
  retention: 60d
aibridgeproxy:
  enabled: true
  listen_addr: ":8888"

After:

ai_gateway:
  enabled: true
  retention: 60d
ai_gateway_proxy:
  enabled: true
  listen_addr: ":8888"

CLI flags follow the same mapping with the --aibridge-* to --ai-gateway-* prefix change.

HTTP API

The canonical API path is now /api/v2/ai-gateway (and /api/v2/ai-gateway/proxy). The legacy /api/v2/aibridge and /api/v2/aibridge/proxy routes are retained for backward compatibility and continue to serve the same handlers.

If you have external integrations or agents calling the API directly, update them to the new path at your convenience. No immediate action is required.

AI clients (such as Claude Code, Codex, and other tools) that are configured with a base URL pointing at the legacy /api/v2/aibridge path continue to work, but should be updated to the new /api/v2/ai-gateway base URL.

Metrics

The metric prefixes have been renamed:

Deprecated prefix	New prefix
`coder_aibridged_*`	`coder_ai_gateway_*`
`coder_aibridgeproxyd_*`	`coder_ai_gateway_proxy_*`

Both the old and new metric names are emitted simultaneously today. Every series is exported under both prefixes from the same underlying collector, so existing dashboards, alerts, and recording rules keep working immediately after upgrade with no changes.

The old prefixes are retained for backward compatibility with no planned removal date. To keep your observability aligned with the new names:

Update Grafana dashboards, Prometheus alerting rules, and recording rules to reference the new coder_ai_gateway_* and coder_ai_gateway_proxy_* names.
Verify the new series are present in your monitoring stack (they are emitted as of this release).

Optional: dropping the old names

If you have already migrated to the new names and do not want both prefixes ingested (for example, to avoid doubling cardinality in your time-series database), you can drop the deprecated series at scrape time with Prometheus metric_relabel_configs:

metric_relabel_configs:
  - source_labels: [__name__]
    regex: 'coder_aibridged_.*|coder_aibridgeproxyd_.*'
    action: drop

This keeps the canonical coder_ai_gateway_* and coder_ai_gateway_proxy_* series and discards the deprecated coder_aibridged_* and coder_aibridgeproxyd_* ones before they are stored. Only do this once your dashboards, alerts, and recording rules reference the new names.
