Muse Spark 1.3 improves Meta's coding tools
Meta released Muse Spark 1.3 late Wednesday, the newest iteration of its AI model. The company says it is better at coding and at agentic tasks -- work that AI can do work with less human help.
The model scored well on benchmark tests, placing it among the leading models from OpenAI and Anthropic. Meta AI chief Alexandr Wang said the release lays the groundwork for future personal AI assistants.
Meta still needs people to use what it builds
Meta has been spending an enormous amount on AI, so investors understandably want to see something come out of it. Muse Spark 1.3 is not a dramatic new iteration, but it is a sign that Meta's models are improving and that it can compete with offerings from frontier labs.

The bigger test is whether these improvements lead to products consumers actually use and, eventually, products that can help pay for Meta's massive AI investment.
