Original GitHub issue: https://github.com/ollama/ollama/issues/16025

What is the issue?

Environment:

Ollama: 0.23.1
Claude Desktop: 1.6259.1
macOS: arm64 (Apple Silicon)
Mac: MacBook Air

Description:
ollama launch claude-desktop successfully puts Claude Desktop into 3P gateway mode and writes a valid config to ~/Library/Application Support/Claude-3p/configLibrary/, but Claude Desktop rejects all Ollama Cloud models during discovery.
Steps to reproduce:

export OLLAMA_API_KEY=<valid_key>
ollama launch claude-desktop
Claude Desktop opens in Cowork 3P · Gateway mode
Model dropdown shows only "Legacy Model" with no selectable models
Sending a message fails with: There's an issue with the selected model (claude-sonnet-4-6). It may not exist or you may not have access to it.

Diagnostic details:
The gateway config is correctly written:
json{
"disableDeploymentModeChooser": true,
"inferenceGatewayApiKey": "",
"inferenceGatewayAuthScheme": "bearer",
"inferenceGatewayBaseUrl": "https://ollama.com",
"inferenceProvider": "gateway"
}
The API key works — curl to /v1/models returns 39 models in valid OpenAI-compatible format:
json{"object":"list","data":[{"id":"kimi-k2.6","object":"model","created":1774915200,"owned_by":"ollama"},{"id":"deepseek-v4-pro","object":"model","created":1776988800,"owned_by":"ollama"},...]}
curl to /api/tags also returns all 39 models successfully.
Key log line from ~/Library/Logs/Claude-3p/main.log:
[warn] [custom-3p] Gateway /v1/models returned 0 usable models { rawCount: 39 }
[info] [custom-3p] Model discovery: not supported by provider; picker = 0 (empty)
Claude Desktop fetches all 39 models but filters every single one out as "not usable." It then falls back to claude-sonnet-4-6 which doesn't exist on Ollama Cloud.
What I tried (none worked):

Restore and relaunch with fresh API key
Full quit and restart of Claude Desktop
Manually adding inferenceGatewayModels array to the config — ignored by Claude Desktop
Multiple API keys — all return models via curl but fail in Claude Desktop

Additional context:
This was working previously. It broke after a recent update (Claude Desktop 1.6259.1 or Ollama 0.23.1). The /v1/models response appears to be standard OpenAI-compatible format, so Claude Desktop's model validator may now require additional fields (e.g., capabilities, context_length) that Ollama Cloud doesn't provide.

I have the same problem, unfortunately I couldn’t solve it, we produced some solutions to see what we can do with codex, but it doesn’t work, the last claude update broke the system.

Unfortunately, Anthropic has removed support for non Claude models. Removed the integration.
