FireConnect routes LangChain Deep Agents Code (dcode) through Fireworks AI models. See the FireConnect overview for install and CLI basics.

​
Prerequisites

Azure routing not implemented yet for Deep Agents. fireconnect deepagents on always configures direct Fireworks, even when global config has --provider azure. See Microsoft Foundry in FireConnect.

​
Enable Fireworks routing

fireconnect login
fireconnect deepagents on
source ~/.zshrc   # keychain mode: load FIREWORKS_API_KEY for dcode
Or pass the key once: 
fireconnect deepagents on --api-key fw_...
Restart dcode after on, model select, model reset, or off if it is already running. 
fireconnect deepagents status

​
Default model

Deep Agents routes a single default model. The default is glm-fast-latest, written to config as fireworks:<model-id>.

​
What gets written

FireConnect edits ~/.deepagents/config.toml:
  • Sets [models].default to fireworks:<model> and configures [models.providers.fireworks] with the Fireworks OpenAI-compatible base URL (https://api.fireworks.ai/inference) and api_key_env = "FIREWORKS_API_KEY"
  • Stores your Fireworks API key in the FireConnect keychain (via login or deepagents on --api-key) and installs a shell hook that exports FIREWORKS_API_KEY for dcode
  • FireConnect does not write ~/.deepagents/.state/auth.json — use dcode’s /auth for credentials stored in that file
FireConnect snapshots config.toml under ~/.fireconnect/deepagents/ before the first change. Running fireconnect deepagents off restores it byte-for-byte.

​
Browsing and picking models

fireconnect deepagents model list              # browse serverless endpoints
fireconnect deepagents model select            # pick Deep Agents' default model
fireconnect deepagents model select --search glm
Fire Pass keys (fpk_...) show Fire Pass-supported routers only.

​
CLI reference

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

​
Switch models

fireconnect deepagents on --main glm-5p1

​
Turn off Fireworks routing

fireconnect deepagents off
This restores your previous config.toml from the backup in ~/.fireconnect/deepagents/.

​
Use a non-default config file

fireconnect deepagents on --config-path /path/to/config.toml
