What is Claude Opus 4.7?
Claude Opus 4.7 is Anthropic's flagship large language model, released April 16, 2026. It specializes in agentic coding, long-horizon reasoning, and high-resolution vision, offering a 1M-token context window and advanced tool-use capabilities for complex, autonomous software engineering and knowledge-work workflows.
Use it privately on Venice
On Venice, Claude Opus 4.7 runs under an anonymized privacy tier — your prompts are not stored, profiled, or used for training. You get the same frontier coding, reasoning, and vision capabilities with per-token billing and no subscription, while keeping your usage history private from Anthropic. It is not open-source and not uncensored, but it is permissionless to access.
What can it do?
- •Top-tier agentic coding and long-horizon software engineering capabilities.
- •Enhanced vision with higher-resolution image input and improved visual reasoning for documents, charts, and UI mockups.
- •1M-token context window for analyzing large codebases and extended multi-step workflows.
- •Advanced reasoning with native support for function calling, structured JSON output, web search, and multiple image inputs per turn.
- •Precise instruction following with self-verification on ambiguous, multi-step tasks.
- •Closed and proprietary — no open weights, so self-hosting or fine-tuning is impossible.
- •Premium per-token cost on Venice compared to open-weight rivals.
- •Not uncensored — Anthropic applies safety guardrails that block certain high-risk cybersecurity prompts and other restricted uses.
- •Some evaluations suggest regression on very long-context multi-needle retrieval compared to prior Opus versions.

Anthropic's flagship with vision, tool use, and the strongest coding performance in the Claude family.
What is it good for?
- •Autonomous software engineering and agentic coding across large codebases.
- •Multi-step research and knowledge-work workflows with web search and tool calling.
- •High-resolution document and chart analysis with vision inputs.
- •Long-form technical writing and content generation within 1M-token contexts.
- •Building structured-output pipelines with JSON schema compliance.
Prompting tips
- •Use explicit, detailed instructions — Opus 4.7 follows directions precisely and benefits from clear constraints.
- •Leverage its reasoning capabilities for difficult coding and agentic problems where step-by-step verification improves output quality.
- •Provide high-resolution images for visual reasoning tasks; the model accepts multiple image inputs in a single turn.
- •Break complex agentic workflows into verifiable sub-tasks — the model self-checks outputs when instructed.
