Recommended models

Browse live pricing and availability with fireconnect model list, then apply a choice with fireconnect <harness> on --model <id> or slot flags such as --sonnet.

fireconnect claude on --model glm-fast-latest --sonnet kimi-fast-latest

Serverless short IDs

These IDs apply to direct Fireworks routing and expand to full Fireworks paths automatically. With Microsoft Foundry, pass your Foundry model instead (for example, FW-GLM-5.2) via --model.

Short ID	Best for	Notes
`glm-latest`	All-around use, agentic tasks	Version-tracking router; strong reasoning, 1M context.
`glm-fast-latest`	Latency-sensitive agentic use	Default for `main`, `opus`, and `fable` slots in Claude Code. Version-tracking router on the high-speed Fast serving path (100+ tok/s), at a higher per-token price. 1M context.
`glm-5p2-fast`	Latency-sensitive agentic use	Same as `glm-fast-latest` but pinned to GLM 5.2 rather than version-tracking. 1M context.
`kimi-fast-latest`	General use (lighter)	Default `sonnet` slot in Claude Code. Fast Kimi variant with vision support.
`glm-5p1`	General use (lighter)	Pinned GLM 5.1; use with `--sonnet glm-5p1` if you prefer it over the default.
`deepseek-v4-flash`	Background / fast tasks	Default `haiku` and `subagent` slots in Claude Code. Lowest latency.
`firerouter`	Automatic cost routing	Sends simple work to open models and hard work to Claude Opus 4.8. See FireRouter.

Fire Pass keys

Fire Pass keys (fpk_...) default all slots to glm-fast-latest. The model browser shows Fire Pass-supported routers: glm-latest, glm-fast-latest, glm-5p2-fast, kimi-fast-latest, and kimi-k2p7-code-fast. Fire Pass works with direct Fireworks routing only. Fire Pass keys are not supported on Codex, Microsoft Foundry, or --model firerouter in FireConnect (on any harness).

Codex does not support Fire Pass keys yet. Use a standard Fireworks API key (fw_...) with Codex.

Per-harness defaults

Claude Code uses multi-slot aliases (main, opus, sonnet, haiku, fable, subagent). See Claude Code for the full mapping table. Other harnesses set a single default model on on. Pass --model <id> to override.
