Croche runs the model for you; usage is charged to your project’s credit. Your app chooses which model to use through its config.
For coding agents: this page is available at https://docs.croche.ai/models.md.

Recommended models
Section titled “Recommended models”| Model | When to use it | USD / 1M tokens (input / output) | Latency in the comparison below |
|---|---|---|---|
deepseek/deepseek-v4.1-flash | Recommended default for text + images and low-latency chat | $0.2002 / $0.9856 | Median 0.9 s, p90 1.6 s; observed ~$0.00013/turn |
openai/gpt-6-luna | Text + image alternative; fallback subject to the reasoning limits below | $0.1114 / $0.5571 | Not measured in this comparison |
deepseek/deepseek-v4-flash-0731 | Text-only apps seeking cheaper output than V4.1; not for image input | $0.1773 / $0.6584 | Not measured in this comparison |
xiaomi/mimo-v2.6-flash | Low token cost, but only background or latency-tolerant work | $0.14 / $0.29 | Median 11.2 s, p90 23.5 s, max 54 s |
anthropic/claude-opus-5.5 | Work/productivity where quality justifies higher cost; not recommended for entertainment/chat companions | $4.5455 / $22.7273 | Not measured in this comparison |
openai/gpt-6.1-sol | Work/document agents that accept higher cost for quality; not recommended for entertainment/chat companions | $2.2286 / $11.1429 | Not measured in this comparison |
Prices are estimates from the Studio catalog’s 2026-10-05 snapshot, in USD per million input/output tokens, not a fixed per-turn charge. MiMo has the lowest output price in this shortlist, but the lowest token price is not the fastest response.
Latency and observed turn cost above come from one 32-turn Croche Chat comparison on 2026-10-13, not a service guarantee or a general benchmark. Prompt size, output length and workload affect both time and cost. Measure your app; do not extrapolate those timings to the models marked unmeasured.
Set project-level config.model explicitly using this table. A coding agent should infer
whether the app sends images from the feature or existing code, and preserve a model the user
explicitly chose. Do not select the text-only option for an app that sends images.
Set the model
Section titled “Set the model”Your app can choose the model. Set model inside the config passed to Croche.open,
not as a top-level open option:
const config = { model: 'deepseek/deepseek-v4.1-flash', instructions: 'You are a friendly guide. Keep replies brief.',};// Use this as the config option in your existing Croche.open call.| Scope | Config field |
|---|---|
| Project | config.model |
| Project language | config.languages.<tag>.model |
| Agent | config.agents.<agentId>.model |
| Agent language | config.agents.<agentId>.languages.<tag>.model |
For the selected agent and language, later applicable levels override earlier ones in that
order: project → project language → agent → agent language. Omitting model at one level
inherits the preceding applicable value. Modes do not declare model.
See the quickstart for a complete Croche.open call with project setup and
storage, or app config for language selection and config updates.
When model is unset
Section titled “When model is unset”The default when no applicable config level sets model is
deepseek/deepseek-v4.1-flash, with openai/gpt-6-luna as fallback.
That fallback applies only when reasoning is default or off. With low, medium,
or high, the fallback is dropped; do not promise an automatic switch to the alternative.
This default is live. Set config.model explicitly when your app needs a particular model.
Listing an alternative is not a guarantee that every explicit model choice automatically
falls back to it. Public SDK package availability remains a separate release check.
Allowed model IDs
Section titled “Allowed model IDs”Use an exact ID below. This list reflects the current SDK candidate, checked on 2026-10-13; public package availability remains pending verification. Match it to the SDK version you ship. The full supported selection is also available in Studio.

An ID outside this list is not a supported app config choice. Do not guess IDs from another product’s catalog. An allowed ID is not a claim that every model accepts every input type; use the recommendations above for text and image input.
