<harness> is one of: claude, opencode, codex, pi, cursor, vscode, deepseek.
There is no model select command. Always use on --model.
--model sets main only; use slot flags or --interactive for the rest. Claude adds [1m] on 1M-context models (not subagent). Re-running on without flags keeps your current mapping.
Latest vs Fast
FireConnect short IDs follow the same Serverless serving paths as the API:
Prefer
*-latest / *-fast-latest unless you need a pin. Browse live IDs and prices with fireconnect model list.
Which model when
Also useful from
fireconnect model list: minimax-latest / qwen-plus-latest (cheaper vision), kimi-k2p7-code / kimi-k2p7-code-fast (code-focused Kimi).
The pinned
deepseek-v4-flash serverless model is deprecated. FireConnect v0.9.3+ migrates existing Claude defaults to deepseek-flash-latest, which currently resolves to deepseek-v4-flash-0731. Prefer the -latest alias so future model upgrades do not require another config change.US-only
For US-only inference (compliance), pass the full router path withon --model. FireConnect does not yet expand the short US slugs to routers (unknown short IDs map to accounts/fireworks/models/..., which is wrong for these endpoints).
Limits
- Fire Pass (
fpk_...): Claude defaults tokimi-fast-latest. Catalog is limited. Not on Codex. FireConnect rejects--model firerouterwith a Fire Pass key on every harness; use anfw_...account key for FireRouter. - Foundry: pass the Azure deployment name (
FW-GLM-5.2), not a short ID. Claude Code and DeepSeek Harness do not support Foundry. - FireRouter: standard key only (
fw_...), not Fire Pass. Cursor / DeepSeek Harness need workspace BYOK for Anthropic pass-through.
Troubleshooting
Nothing changed after on --model
Nothing changed after on --model
Restart the harness. For Cursor and VS Code, fully quit the IDE before running
on.Stuck on FireRouter / Fire Pass
Stuck on FireRouter / Fire Pass
FireConnect rejects
--model firerouter when your stored key is Fire Pass (fpk_...), on every harness. Switch to an fw_... account key, then run fireconnect <harness> on --model firerouter and restart the harness.Foundry says the model was not found
Foundry says the model was not found
Pass the Azure deployment name (for example
FW-GLM-5.2), not a serverless short ID.
