Models

Learn which models Sculptor supports and how to configure your API keys.

Overview

Sculptor supports a range of Anthropic and OpenAI models. Depending on how you configure your API keys, Sculptor can run tasks using Claude models or the Codex model. Some model families are currently in beta and have limited feature support.

This page explains which models Sculptor supports and how to configure them.

Anthropic model support

Sculptor supports all major Anthropic models. You can configure Anthropic access using any of the following:

  • Claude Console API key

  • ClaudeMax Team Pro key (beta)

  • AWS Bedrock key (beta)

  • Anthropic API key

Once configured, Anthropic models appear in the model selector when creating or modifying a task.

Anthropic API configuration

Supported Anthropic models

Sculptor currently supports:

  • Claude 3.7 Sonnet

  • Claude 3.5 Sonnet

  • Claude 3.5 Haiku

  • Claude 3 Opus

  • Claude 3 Sonnet

  • Claude 3 Haiku

  • Claude Code 3.7

  • Claude Code 3.5

Model configuration

You can configure Anthropic usage in:

Settings → Account → Manage Claude Access

Once a valid credential is added, all supported Claude/Claude Code models become selectable in the model selector.

You can also set a default model in Settings, which will be used for new tasks.

OpenAI Codex model support (beta)

Sculptor provides beta support for the OpenAI Codex model. This allows you to run tasks using Codex instead of Claude Code, provided you configure an OpenAI API key. Codex behaves similarly to Claude Code for most agent-agnostic features (such as pairing and merging), but several agent-specific capabilities are not yet supported in beta.

To enable Codex:

  1. Go to Settings → Account → Manage OpenAI Access.

  2. Add your OpenAI API key. (OpenAI OAuth is not supported; API key only.)

  3. Codex will appear in the model selector (initially greyed out). After credentials are provided, the model becomes selectable.

  4. You can optionally set your default model to Codex in Settings so future tasks start with it automatically.

Codex model configuration

Codex support is still in early beta. We currently do not support model family swapping mid-session or during fork operations; a chat will only show models belonging to the same family as the one it started with. We also do not support multiple Codex variants or reasoning levels.

Supported features

Codex currently supports:

  • Sending messages

  • Viewing conversation context

  • Compaction

  • Interrupting messages

  • Merge workflows

  • Pairing mode

  • Forking

These features are generally shared with Claude Code and behave similarly.

Unsupported features (beta limitations)

Codex does not currently support:

  • Swapping between model families or reasoning levels

  • MCP servers

  • Custom configurations (e.g., custom slash commands, custom agents, plan mode)

  • Model switching between Codex and Claude Code within the same session or during fork operations

  • OpenAI OAuth (API key only)

Notes

Codex should match Claude Code for most non-agent-specific workflows. However, features that rely on Claude Code’s extended agent system—such as MCP, custom configurations, plan mode, and other container-level capabilities—may not function when using Codex during the beta period.

Summary

Sculptor supports:

  • Full Anthropic model support, including all Claude 3.x and Claude 3.5/3.7 variants

  • Claude Code models (beta) for code-aware workflows

  • OpenAI Codex (beta) with limited feature support

Configure your keys in Settings → Account to enable the model families you want to use.
