Is Muse Spark 1.2 worth it in 2026?
Muse Spark 1.2 sits at rank 4 of 20 for general text with an Elo of 1498, backed by 3275 human votes, suggesting solid conversational quality. Its context window of 1,048,576 tokens is a standout feature for long-document work. The Artificial Analysis Intelligence Index is 56.8 out of 100 and the Coding Index is 72.2 out of 100, but the LM Arena coding Elo of 1535 places it at rank 19 of 20, meaning coding performance in head-to-head human preference is near the bottom of this field. Pricing at 1.25 USD per 1M input and 4.25 USD per 1M output tokens is moderate.
General chat and long-document work where the strong text Elo rank 4 of 20 and the 1,048,576-token context window are most relevant.
Coding rank is 19 of 20 with an Elo of 1535, making it a poor choice for coding-focused tasks despite a reasonable Artificial Analysis Coding Index score.
