## How they compare

Meta pitches Muse Spark at agentic coding, tool use and computer use, which makes it a candidate for the main model in a coding agent. Morph sits next to that model. Its Fast Apply takes the changed lines a large model writes, marked with existing-code comments, and merges them into the full file at 10,500+ tokens per second with up to 98% accuracy. Around it, Morph offers WarpGrep for repository search, Compact for context compression and Reflex for classification, plus fine-tuning. Muse Spark writes the plan and the diff. Morph applies it.

Together they cut cost on the expensive part of the bill. Muse Spark 1.3 output costs $4.25 per million, and Morph reports about 40% fewer tokens when the big model writes diffs instead of full-file rewrites. Morph's approach also avoids brittle search-and-replace tool calls. Its 2 to 4% merge error rate means tests or linting should check edits before they ship. Meta's API is still in preview, so teams should keep a fallback model in mind, which Morph's model-agnostic apply step makes easy.

## What each one does

### Meta

Meta has moved from open Llama releases toward its own closed API. Meta Superintelligence Labs builds the Muse family, and in July 2026 Meta opened a public preview of the Meta Model API with Muse Spark 1.1, a multimodal reasoning model aimed at agentic coding, tool use and computer use. The current lineup runs through Muse Spark 1.3 with a 1M token context. Standard pricing is $1.25 in and $4.25 out per million tokens, with cached input at $0.15, and the endpoint speaks OpenAI Chat Completions, Anthropic Messages and a stateful agentic format.

### Morph

Morph builds small, very fast specialist models that sit beside a big coding model inside an agent. Its flagship is Fast Apply. The frontier model writes only the changed lines with // ... existing code ... markers, and Morph merges them into the full file at 10,500+ tokens per second with up to 98% accuracy. It is the same idea behind Cursor's instant apply, offered as an OpenAI-compatible API.

## Which is best, and when

### Choose Meta for
