Code execution

from OpenAI, Google and AnthropicCodedocs.opper.ai

Give the model a sandbox and it writes and runs code to answer: maths, data analysis, charts and file transforms, with the output folded into its reply. OpenAI's code interpreter, Gemini's code execution and Claude's code execution all run through Opper on the same key, passed through as each provider defines them. Claude's runs on Anthropic's own route, not on Bedrock or Vertex.

Add code execution on Opper

Set up with agents

Paste this into your coding agent (Claude Code, Cursor, Codex, and more) and it will set up and build with Opper for you.

Code execution tools on Opper

Each one has its own page with setup, code and the models it works with.

OpenAI code interpreter

GPT models write and run Python in a sandbox, on the Responses endpoint.

Codecode_interpreter

Gemini code execution

Gemini runs code to work out its answer, on generateContent.

CodecodeExecution

Claude code execution

Claude runs code in Anthropic's sandbox, on Anthropic's own route.

Codecode_execution

OpenAI: code_interpreter on /v3/compat/responses
Google: codeExecution on /v3/compat/v1beta/models/{model}:generateContent
Anthropic: code_execution (Anthropic's own route only) on /v3/compat/v1/messages

More tools on Opper

Web search

Let any model search the web mid-answer and cite its sources. Native search where the model has it, Jina, Searchbase, Exa or Linkup everywhere else.

Searchopper:web_search

Web fetch

Turn any URL into clean markdown a model can read. Runs on Jina in the EU.

Read/v3/tools/web/fetch

Rerank

Reorder search results by relevance before they reach the model. Cohere Rerank and BGE.
