Open Models

Use auto, version-tracking aliases, fast tiers, or pinned Fireworks open models in coding workflows.

Use a Fireworks open model directly when you want Fireworks to serve every turn. FireConnect automatically registers the coding-ready catalog when you connect a harness.

Start with auto

auto chooses from frontier open models for each new user turn. It is the default on a standard Fireworks key.

Use auto-instant when you want a latency-first open-model mix. If fast models are disabled by model governance, use auto.

fireconnect claude

Restart Claude Code, open /model, and select Auto. No --model flag is required.

Choose a family, tier, or version

Use --model only when you want a specific family, tier, or version:

fireconnect claude --model glm-latest

Kind	Example IDs	Behavior
Latest	kimi-latest, glm-latest, deepseek-flash-latest	Tracks the current version in the model family
Fast	kimi-fast-latest, glm-fast-latest	Favors lower latency at a higher token price
Pinned	kimi-k3, glm-5p3, glm-5p3-flash	Stays on the named version

Prefer *-latest unless you need a pinned version.

Current aliases

These are all serverless aliases as of September 27, 2026. Aliases can move to newer models or be retired, so treat this list as a snapshot. The serverless models endpoint always shows the current set, and fireconnect model list shows the current coding aliases.

Alias	Current model	Tier	Input
kimi-latest	kimi-k3	Standard	Text and images
kimi-fast-latest	kimi-k3	Fast	Text and images
glm-latest	glm-5p3	Standard	Text
glm-fast-latest	glm-5p3	Fast	Text
glm-flash-latest	glm-5p3-flash	Standard	Text and images
deepseek-flash-latest	deepseek-v4p1-flash	Standard	Text and images
minimax-latest	minimax-m3	Standard	Text
qwen-max-latest	qwen3p8-max	Standard	Text and images

qwen-max-latest is not in the coding catalog, so fireconnect model list does not show it.

Aliases may change as Fireworks adds and retires models. For example, deepseek-pro-latest is deprecated. Check the current list before you hard-code an alias, as shown in Find a model ID.

Find a model ID

List current models and aliases with FireConnect:

fireconnect model list
fireconnect model list --search glm
fireconnect model list --refresh

The catalog is cached for one hour. --refresh fetches the latest copy.

Without FireConnect, call the serverless models endpoint:

curl "https://api.fireworks.ai/v1/serverless/models?use_cases=coding" \
  -H "Authorization: Bearer $FIREWORKS_API_KEY"

Each entry’s aliases field lists the aliases that point to that model, such as accounts/fireworks/routers/glm-latest for glm-5p3. Use the last part, glm-latest, as the model ID. Remove use_cases=coding to list every serverless model.

This command lists models for FireConnect. To construct a custom firerouter/... ID without FireConnect, use the FireRouter supported models.

Check image support

glm-latest and glm-fast-latest are text-only. Image support for other aliases depends on the model currently behind each alias. See the Input column in Current aliases, and check fireconnect model list before sending images.

If an image reaches a text-only model in Claude Code, use /rewind or switch to a vision-capable model such as Kimi or glm-5p3-flash.

Use US-only models

Use the current model IDs, endpoint, and pricing guidance from US-only Serverless.
