Fixes #27361 (CODAGT-832). ## Problem When an Agents model was configured under a non-gateway provider type (e.g. Anthropic or OpenAI) with a model ID whose first `/`- or `:`-segment matched a built-in provider name (`anthropic`, `azure`, `bedrock`, `google`, `openai`, `openai-compat`, `openrouter`, `vercel`), `chatprovider.ResolveModelWithProviderHint` parsed it as a canonical `provider/model` reference: the prefix was stripped and the request rerouted to the embedded provider type, overriding the provider the admin explicitly assigned. LLM gateways (e.g. LiteLLM) that namespace their catalogs as `bedrock/...` or `anthropic/...` behind an Anthropic- or OpenAI-type provider failed with an opaque upstream "Model not found", and escaping was impossible (`bedrock/bedrock/...` still rerouted). ## Fix A valid provider hint is now authoritative: `ResolveModelWithProviderHint` returns the assigned provider and the verbatim model ID whenever a hint is present. Canonical `provider/model` and `provider:model` parsing applies only to hint-less resolution paths. Every production call site derives the hint from the model config's explicitly assigned AI provider, so the assignment always wins. The save-time guard rejecting slash-namespaced models on OpenRouter-like providers typed as `openai` (provider named `openrouter` or hosted at `openrouter.ai`) is kept: that combination remains a misconfiguration whose correct fix is the `openrouter` provider type, and rejecting it early beats a confusing upstream error. Its wording no longer claims prefix stripping happens. ## Back-compat note A pre-existing config that relied on stripping (e.g. model `anthropic/claude-x` assigned to an Anthropic-type provider pointing at the real Anthropic API) now sends the prefixed ID verbatim and will get a clear upstream model-not-found error; the admin fixes it by editing the model ID. Nothing in the product ever suggested the canonical form for assigned models. ## Validation - Unit: `TestResolveModelWithProviderHint` updated (hints preserve `bedrock/...`, `anthropic/...`, `provider:...` verbatim; hint-less canonical parsing unchanged), red-green verified against the old ordering. Gateway and openai-type provider routing tests assert verbatim pass-through end to end. - Full `./coderd/x/chatd/...` suites plus `TestCreateChatModelConfig`, `TestUpdateChatModelConfig`, and `TestValidateChatModelConfigProviderModel` pass. - Remote dogfood UAT on real models (PASS): an openai-type provider pointed at a Vercel AI Gateway mount returned a real completion for `anthropic/claude-haiku-4.5`, with trace logs confirming `provider=openai model=anthropic/claude-haiku-4.5` (verbatim, not rerouted); gateway-type (`openai-compat`) routing with `deepseek/deepseek-v4-pro-0813` and the model catalog/picker regressions pass. > Mux acted on Mike's behalf to create this PR.
Coder is a self-hosted platform for cloud development environments and AI coding agents. Workspaces are defined with Terraform, connected through a secure Wireguard® tunnel, and automatically shut down when not used. Coder Agents runs a native AI coding agent whose loop executes in the control plane on your infrastructure, with no API keys in workspaces.
- Define cloud development environments in Terraform
- EC2 VMs, Kubernetes Pods, Docker Containers, etc.
- Automatically shutdown idle resources to save on costs
- Onboard developers in seconds instead of days
- Delegate coding work to AI agents on your infrastructure
- Bring any model (Anthropic, OpenAI, Google, Bedrock, self-hosted)
- No LLM credentials in workspaces, user identity on every action
- Centralized model governance, cost tracking, and audit logging
Quickstart
The most convenient way to try Coder is to install it on your local machine and experiment with provisioning cloud development environments using Docker (works on Linux, macOS, and Windows).
# First, install Coder
curl -L https://coder.com/install.sh | sh
# Start the Coder server (caches data in ~/.cache/coder)
coder server
# Navigate to http://localhost:3000 to create your initial user,
# create a Docker template and provision a workspace
Install
The easiest way to install Coder is to use the
install script for Linux
and macOS. For Windows, use the latest ..._installer.exe file from GitHub
Releases.
curl -L https://coder.com/install.sh | sh
You can run the install script with --dry-run to see the commands that will be used to install without executing them. Run the install script with --help for additional flags.
See install for additional methods.
Once installed, you can start a production deployment with a single command:
# Automatically sets up an external access URL on *.try.coder.app
coder server
# Requires a PostgreSQL instance (version 13 or higher) and external access URL
coder server --postgres-url <url> --access-url <url>
Use coder --help to get a list of flags and environment variables. See the install guides for a complete tutorial.
