Morph serves open-weight models on inference kernels built for coding agents. Same weights, a different engine. How →

Run an open-weight model

Point any OpenAI SDK at https://api.morphllm.com/v1. Existing code only needs a new model string. The Anthropic SDK works too, at /v1/messages (see Endpoints).

Models

Every model supports tool calls, JSON mode and JSON schema, logprobs, and reasoning. Per-token rates are on the pricing page and live at /api/models/json. DeepSeek V4.1 Flash Abliterated is served behind approval.

Built for agent loops

Three things change when the caller is an agent rather than a chat window.
  • Prefix caching is on for every model with no configuration. Set an x-session-id header and each turn lands on the worker already holding its prefix.
  • Agent programs: tag turns with a run_id and the scheduler pins the run to its KV cache, resumes it first after a tool call, and admits the whole run under load.
  • Standby: service_tier: "standby" runs on spare capacity at half price. Sheds a fast 429 when a region is busy. Built for crons, batch jobs, and evals.
Speed comes from a speculator trained on each model’s own coding output (3.07x vs. 1.93x for a generic draft) and FP4 kernels tuned per GPU. How we optimize for codegen →

Specialized models

Small models that take one job off the main agent. Same key, same base URL. Fast Apply and WarpGrep also ship as the morph CLI with skills for Claude Code, Cursor, Codex, and OpenCode (an MCP server remains for hosts without a shell):

Dedicated endpoints

Reserve capacity for one model on its own pool. Hourly plans, your own endpoint URL, same OpenAI client. Dedicated endpoints →
