Venice

Venice provides an OpenAI-compatible API for hosted text models. Fabro enables the venice provider in its built-in catalog and maps stable Fabro model slugs to Venice’s API model IDs.

Prerequisites

A Venice account
An inference API key from venice.ai/settings/api
A running Fabro server

Configure credentials

Store the API key in the target Fabro server vault:

fabro provider login --provider venice

# For a non-default remote server:
fabro provider login --server https://your-fabro.example --provider venice

# Or set the vault token directly:
fabro secret set VENICE_API_KEY
fabro secret --server https://your-fabro.example set VENICE_API_KEY

Standalone SDK usage outside a Fabro server can use an env-backed credential source explicitly:

export VENICE_API_KEY=<api-key>

Fabro sends bearer-authenticated Chat Completions requests to https://api.venice.ai/api/v1.

Fabro model slug	Venice API ID	Context	Max output	Role and aliases
`kimi-k3`	`kimi-k3`	1,000,000	131,072	Alias `kimi`
`kimi-k3-fast`	`kimi-k3-fast-api`	1,000,000	131,072	Alias `kimi-fast`
`grok-4.6`	`grok-4-6`	500,000	32,000	Aliases `grok`, `grok46`, `grok-46`
`glm-5.3`	`z-ai-glm-5-3`	1,000,000	131,072	Aliases `glm`, `glm5`, `glm53`, `glm5.3`, `glm-5-3`
`deepseek-v4-flash`	`deepseek-v4-flash-0731`	1,000,000	32,768	Provider default; aliases `deepseek`, `deepseek-v4`, `deepseek-flash`
`deepseek-v4-pro`	`deepseek-v4-pro-0813`	1,000,000	32,768	Alias `deepseek-pro`
`qwen3.8-max`	`qwen-3-8-max`	1,000,000	131,072	Aliases `qwen`, `qwen-max`, `qwen3.8`, `qwen-3.8`, `qwen38`, `qwen-3.8-max`, `qwen38-max`
`qwen3.8-27b`	`qwen-3-8-27b`	262,144	131,072	Aliases `qwen-27b`, `qwen-3.8-27b`, `qwen38-27b`

Venice API IDs are also valid provider-scoped selectors. Fabro persists the stable Fabro slug and the selected provider when it creates a run.

Select Venice explicitly

Some Venice models use the same stable slugs as direct providers. An unqualified selector chooses the highest-priority ready provider. For example, deepseek can select the direct DeepSeek provider when both API keys are configured. Pin Venice when the run must use Venice:

fabro model list --provider venice
fabro model test --provider venice --model deepseek-v4-flash --deep
fabro run workflow.fabro --provider venice --model deepseek-v4-flash

In a workflow stylesheet:

workflow.fabro

digraph Example {
    graph [
        model_stylesheet="
            *         { provider: venice; model: deepseek-v4-flash; }
            .complex  { provider: venice; model: qwen; }
            .fast     { provider: venice; model: kimi-fast; }
        "
    ]

    start [shape=Mdiamond, label="Start"]
    work  [label="Implement", class="complex"]
    check [label="Check", class="fast"]
    exit  [shape=Msquare, label="Exit"]

    start -> work -> check -> exit
}

The generic Qwen aliases qwen and qwen3.8 select Qwen 3.8 Max. Use a size-specific alias such as qwen-27b to select Qwen 3.8 27B.

Capabilities and reasoning

All included models support tool calling and reasoning. Kimi K3, Kimi K3 Fast, Grok 4.6, Qwen 3.8 Max, and Qwen 3.8 27B also accept image input. Fabro exposes native reasoning-effort controls only when Venice supports them:

Model	Reasoning effort values
`grok-4.6`	`low`, `medium`, `high`, `xhigh`
`glm-5.3`	`low`, `high`, `max`
`deepseek-v4-flash`	`low`, `high`, `max`
`qwen3.8-27b`	`low`, `medium`, `xhigh`

The other models reason by default but do not expose a Venice reasoning-effort control. Fabro omits sampling parameters for Kimi and DeepSeek because those routes do not use them with their configured reasoning behavior.

Pricing and prompt caching

The built-in catalog uses Venice’s published prices per million tokens:

Model	Uncached input	Cache hit	Output
`kimi-k3`	$3.75	$0.375	$18.75
`kimi-k3-fast`	$4.50	$0.45	$22.50
`grok-4.6`	$2.27	$0.57	$6.80
`glm-5.3`	$1.75	$0.325	$5.50
`deepseek-v4-flash`	$0.175	$0.035	$0.35
`deepseek-v4-pro`	$1.65	$0.165	$4.95
`qwen3.8-max`	$2.50	$0.3125	$7.50
`qwen3.8-27b`	$0.45	n/a	$3.20

Fabro reports cached input separately when Venice returns cache usage for the selected model. Prices and model availability can change upstream; use fabro model list --provider venice to inspect the catalog shipped with your Fabro version and the Venice model catalog for the current upstream service.

Troubleshooting

“No credential was found for provider ‘venice’” — Store VENICE_API_KEY in the server vault with fabro provider login --provider venice. Pass --server when configuring a remote Fabro server. A shared model used another provider — Pin Venice with --provider venice or provider: venice in the workflow stylesheet. Unqualified selectors use provider priority. A Venice API model ID is rejected without a provider — Use the stable Fabro slug for portable selection, or qualify the API ID with the provider, such as venice:qwen-3-8-max.
