## Summary Consolidate chat model management and runtime availability into a single organization model collection contract. The organization model response now includes provider availability, unavailable reasons, and unsupported-provider details, so callers no longer need a separate availability request. Depends on #28439. ## Problem The organization-scoped API exposes two overlapping representations of the same chat models: ```text GET /api/experimental/organizations/{organization}/chats/models GET /api/experimental/organizations/{organization}/chats/models/available ``` The collection route returns organization-owned model configurations and redacted provider descriptors. The availability route returns a second catalog-oriented response with provider availability and synthetic catalog entries. Callers must fetch, reconcile, and cache both responses even though they describe the same effective set of models. This creates duplicated server logic and separate SDK, OpenAPI, and frontend types. It can also produce inconsistent client state when one request succeeds while the other fails or when the two responses are refreshed at different times. ## Fix Return all model-management and runtime-availability information from the organization model collection route: ```text GET /api/experimental/organizations/{organization}/chats/models ``` `OrganizationChatModelsResponse` continues to return the caller-readable organization model configurations and redacted provider descriptors. Provider descriptors now also include: - `available` - `unavailable_reason` The response additionally includes `unsupported_providers`, allowing clients to explain configurations that the Agents harness cannot use. Frontend model settings, agent creation, existing chat recovery, and model override surfaces now consume this single collection query. This keeps model ownership, caller visibility, provider availability, and unsupported-provider guidance in one cache entry and one authorization path. The default-organization compatibility route remains available: ```text GET /api/experimental/chats/models ``` It now returns the same consolidated `OrganizationChatModelsResponse` contract instead of the former availability response. ## Breaking change This removes the separate organization model availability endpoint: ```text GET /api/experimental/organizations/{organization}/chats/models/available ``` Clients using that endpoint must migrate to: ```text GET /api/experimental/organizations/{organization}/chats/models ``` This PR also removes the corresponding public experimental client and schema surface: - `ExperimentalClient.ChatModelAvailability` - `ChatModelAvailabilityResponse` - `ChatModelProvider` - `ChatModelCatalogEntry` - The generated OpenAPI schema and frontend API/query types for the availability endpoint Callers must use `ExperimentalClient.ChatModels` and `OrganizationChatModelsResponse` instead. Availability is now reported on each `ChatModelProviderDescriptor`, and unsupported providers are returned in `OrganizationChatModelsResponse.UnsupportedProviders`. The default-organization compatibility route retains its URL, but its response schema changes from `ChatModelAvailabilityResponse` to `OrganizationChatModelsResponse`. Direct HTTP clients and generated clients that decode the previous response type must be updated even if they do not use the removed organization-scoped `/available` route.

About
Coder is a self-hosted platform for running AI coding agents and cloud development environments on infrastructure you control. It works with any cloud, IDE, OS, Git provider, and IDP.
Coder Workspaces
Coder Workspaces are cloud development environments defined with Terraform, connected through a secure Wireguard tunnel, and automatically shut down when not in use. Agents and developers share the same workspace infrastructure.
- Defined in Terraform: Templates describe the infrastructure for each workspace, from EC2 VMs and Kubernetes Pods to Docker containers.
- Any architecture and OS: Support ARM and x86-64 across Windows, Linux, and macOS from a single deployment.
- Managed by admins: Platform teams create and maintain templates that enforce approved images, resource limits, and security policies.
- Accessed from any IDE: Connect through VS Code, JetBrains, Cursor, a web terminal, remote desktop, or SSH.
- Automatic shutdown: Idle workspaces stop automatically to reduce cloud spend, and restart in seconds when needed.
Coder Agents
Coder Agents is a native AI coding agent built into Coder. The agent loop runs in the Coder control plane on your infrastructure, not in the workspace and not in a vendor's cloud. Developers interact with agents through the web UI or the REST API for programmatic and CI-driven workflows.
- Self-hosted agent loop: The control plane handles planning, model calls, and tool dispatch. Workspaces have zero AI awareness.
- No API keys in workspaces: LLM credentials stay in the control plane.
- Any model: Anthropic, OpenAI, Google, Bedrock, or self-hosted endpoints. Switching is a configuration change.
- Governance and cost controls: Centralized model approval, per-user spend limits, and audit logging.
- Open source and inspectable: The full platform is available to audit and extend.
IDE support
You can use:
-
Any Web IDE, such as
- code-server
- JetBrains Projector
- Jupyter
- And others
-
Your existing remote development environment:
-
A file sync such as Mutagen
Why remote development
Provisioning consistent development environments for a large engineering team is difficult. Each developer has preferences for operating systems, editors, and toolchains, and ensuring a reliable build environment across all of them is a maintenance burden. A missed step during onboarding or an unsupported local configuration can cost hours of debugging.
Remote development solves this by moving the environment off the developer's machine and into managed infrastructure. The developer's laptop becomes a portal into the actual compute where work happens. If a device is lost or replaced, access is simply revoked; no source code or credentials are stored locally.
This approach provides:
- Speed: Server-grade hardware accelerates builds, tests, and large workloads without requiring expensive local machines.
- Consistency: Infrastructure tools such as Terraform, nix, Docker, and Dev Containers produce identical environments for every developer.
- Security: Source code stays on private servers. Users and groups are managed through SSO and RBAC.
- Compatibility: Workspaces share infrastructure configurations with staging and production, reducing configuration drift.
- Accessibility: Browser-based IDEs and remote IDE extensions let developers work from any device, including lightweight laptops, Chromebooks, and tablets.

Why Coder
The key difference between Coder and other platforms is that the entire system, agent loop, control plane, model routing, and workspace provisioning, runs on infrastructure you control.
For agents, this means platform teams can:
- Run the entire agent loop on their infrastructure, with no SaaS dependency for orchestration.
- Define MCP servers, skills, and system prompts centrally so every agent session starts with the same tools, policies, and context.
- Keep LLM credentials out of workspaces entirely.
- Tie every agent action to an authenticated user identity.
- Support air-gapped and restricted-network deployments with self-hosted models.
For workspaces, this means admins can:
- Support any architecture (ARM, x86-64) and operating system (Windows, Linux, macOS).
- Modify pod/container specs, such as adding disks, managing network policies, or setting/updating environment variables.
- Use VM or dedicated workspaces, developing with Kernel features (no container knowledge required).
- Enable persistent workspaces, which are like local machines, but faster and hosted by a cloud service.
Pricing
Coder is free and open source under the GNU Affero General Public License v3.0. All developer productivity features are included in the open source version. A Premium license is available for enhanced support and custom deployments.
How Coder works
Coder workspaces are represented with Terraform, but you do not need to know Terraform to get started. The Coder Registry provides production-ready templates for AWS EC2, Azure, Google Cloud, Kubernetes, and other providers.
Providers and compute environments
Workspaces can include more than just compute. Terraform can add storage buckets, secrets, sidecars, and other resources.
See the templates documentation for details.
What Coder is not
-
Coder is not an infrastructure as code (IaC) platform.
- Terraform is the first IaC provisioner in Coder, allowing Coder admins to define Terraform resources as Coder workspaces.
-
Coder is not a DevOps/CI platform.
- Coder workspaces can be configured to follow best practices for cloud-service-based workloads, but Coder is not responsible for how you define or deploy the software you write.
-
Coder is not an online IDE.
- Coder supports common editors, such as VS Code, vim, and JetBrains, all over HTTPS or SSH.
-
Coder is not a collaboration platform.
- You can use Git with your favorite Git platform and dedicated IDE extensions for pull requests, code reviews, and pair programming.
-
Coder is not a SaaS/fully-managed offering.
- Coder is a self-hosted solution. You must host Coder in a private data center or on a cloud service, such as AWS, Azure, or GCP.
