FireConnect routes OpenCode through Fireworks AI models. See the FireConnect overview for install and CLI basics.

Prerequisites

Enable Fireworks routing

fireconnect login
fireconnect opencode on
Restart OpenCode after enabling, then confirm routing:
fireconnect opencode status

Using Fire Pass

Use your fpk_... key during login or with --api-key:
fireconnect opencode on --api-key fpk_...
FireConnect detects Fire Pass keys and defaults OpenCode to glm-fast-latest.

Default model

OpenCode routes a single default model (no opus/sonnet/haiku alias slots). The default is glm-fast-latest, written to config as fireworks-ai/glm-fast-latest. Short model IDs like glm-5p1 are expanded to full Fireworks paths (for example, accounts/fireworks/models/glm-5p1).

What gets written

FireConnect merges a fireworks-ai provider block into ~/.config/opencode/opencode.json:
  • An OpenAI-compatible adapter pointed at https://api.fireworks.ai/inference/v1
  • A default model set to fireworks-ai/<model-id> (for example, fireworks-ai/glm-fast-latest)
  • Your other providers are left untouched
FireConnect snapshots your original opencode.json before the first change. The snapshot lives in ~/.fireconnect/opencode/. Running fireconnect opencode off restores the file byte-for-byte.

API key handling

  • The API key is stored as {env:FIREWORKS_API_KEY} — never a literal in the config file
  • Keychain mode installs a shell profile hook that exports FIREWORKS_API_KEY="$(fireconnect key export)" when you launch OpenCode
  • OpenCode’s auth.json is never touched

Browsing and picking models

fireconnect opencode model list              # browse serverless endpoints
fireconnect opencode model select            # pick OpenCode's default model
fireconnect opencode model select --search glm
fireconnect opencode model list resolves the API key from the OS keychain or global config. Fire Pass keys (fpk_...) show Fire Pass-supported routers only.

CLI reference

fireconnect opencode on              # Enable Fireworks routing
fireconnect opencode off             # Restore original config
fireconnect opencode status          # Check current provider and model
fireconnect opencode model list      # Browse serverless endpoints
fireconnect opencode model select    # Pick a model interactively
fireconnect opencode model reset     # Reset model to default
fireconnect opencode help            # Show harness-specific help
Run fireconnect opencode help for all options.

Switch models

fireconnect opencode on --main glm-5p1

Turn off Fireworks routing

fireconnect opencode off
This restores your previous opencode.json from the backup in ~/.fireconnect/opencode/.

Use a non-default config file

fireconnect opencode on --config-path /path/to/opencode.json

Fireworks on Microsoft Foundry

OpenCode supports Fireworks on Microsoft Foundry (CLI: --provider azure or on --azure). See the FireConnect overview and Microsoft Foundry integration guide for portal setup.

Configure and enable

export AZURE_API_KEY=<your-azure-api-key>

fireconnect configure \
  --provider azure \
  --base-url https://<resource>.services.ai.azure.com \
  --api-key $AZURE_API_KEY

fireconnect opencode on --main FW-GLM-5.1
One-off routing without changing global config:
fireconnect opencode on \
  --azure \
  --base-url https://<resource>.services.ai.azure.com \
  --main FW-MiniMax-M2.5
Pass your Foundry deployment name with --main — not a Fireworks serverless short ID like glm-latest.

What gets written

FireConnect adds a fireworks-azure provider labeled Fireworks on Microsoft Foundry to opencode.json, pointed at your Foundry OpenAI-compatible endpoint (.../openai/v1). The default model reference becomes fireworks-azure/<deployment-name>. fireconnect opencode model list and model select browse the Fireworks serverless catalog only. With Foundry, switch deployments with on --main <deployment-name>.

Turn off Foundry routing

To switch back to the Fireworks gateway, change the global provider and re-enable:
fireconnect configure --provider fireworks
fireconnect opencode on
To remove FireConnect entirely and restore your original opencode.json:
fireconnect opencode off
See Turn off Foundry routing for details on global config behavior and uninstall.

Built-in provider connection

OpenCode also supports connecting to Fireworks directly without FireConnect:
  1. Type /connect in OpenCode and search for fireworks.ai
  2. Paste your Fireworks API key and press Enter
  3. Type /models and select a model (for Fire Pass, choose a supported model such as GLM Fast Latest)
