Morph

What it does

Morph is an inference API aimed at coding agents. Developers send requests through an OpenAI-compatible endpoint that serves open-weight models including Kimi K3, GLM-5.3, GLM-5.3-Flash, and DeepSeek V4 Flash. It also offers task-specific models: WarpGrep for parallel code search, Fast Apply for merging lazy edit snippets into original files, and Compact for context compaction.

Teams typically either point an existing OpenAI SDK client at the Morph base URL or install the Morph SDK or MCP server so an agent can call Fast Apply and WarpGrep. The quickstart includes a single setup command that migrates a project's LLM calls to Kimi K3, offering a 5% production trial or a full switch, and it can be reversed with morph-setup --restore.

It suits developers and engineering teams building production coding agents that need hosted open-weight models or edit-application tooling. A Morph API key from the dashboard is required. Fast Apply accuracy and speed figures come from Morph's own pages, and plan prices should be checked on the pricing page.

What it can do

• Serve open-weight models (Kimi K3, GLM-5.3, GLM-5.3-Flash, DeepSeek V4 Flash) through an OpenAI-compatible API
• Merge lazy edit snippets into original files with Fast Apply
• Perform parallel code search with WarpGrep
• Compact agent context with the Compact model
• Run a 5% canary trial or full migration of LLM calls to Kimi K3 via a setup command
• Self-host Morph on your own infrastructure

Works with

• OpenAI SDK (OpenAI-compatible endpoint)
• Morph SDK (@morphllm/morphsdk)
• Model Context Protocol (MCP)
• AI SDK
• OpenRouter

Before you choose

• Fast Apply accuracy (98%) and speed claims are reported by Morph on its own pages.
• Per-token rates for Kimi K3 and GLM-5.3 and plan pricing should be verified on the Morph pricing page.

Get started

Set MORPH_API_KEY and call the OpenAI-compatible endpoint or install the SDK.

1. Obtain a Morph API key from the dashboard.
2. Install the SDK with npm install @morphllm/morphsdk, or point the OpenAI SDK at https://api.morphllm.com/v1.
3. Call a model such as morph-kimik3 or use Fast Apply to merge edits into files.

Morph lists startup API credits of up to $5K. Confirm plan prices and any ongoing free usage on the pricing page.
