Meta’s Muse Spark 1.3 raises the pressure on Gemini with stronger benchmark scores and lower pricing
Meta has launched Muse Spark 1.3, putting fresh pressure on Google’s Gemini 3.8 Flash in both benchmark rankings and pricing. According to the source article, Meta CEO Mark Zuckerberg described the release as the company’s biggest jump so far in coding and agent work, while Meta Superintelligence Labs lead Alexandr Wang said the new version cuts unnecessary turns, reduces tool calls by about 20%, lowers token use by about 25%, and holds requirements better in long-running tasks. The model’s reported scores were a major part of the launch narrative. Muse Spark 1.3 posted 75.4 on DeepSWE v1.1, ahead of Claude Opus 5 at 74.0 and GPT-5.6 Sol at 73.0. It also scored 59.4 on SWEAtlas CodeBase QnA, 88.8 on Terminal-Bench 2.1, 98.1 on MRCR 512K-1M, and 62 on the Artificial Analysis intelligence index. On cost, the article said Meta kept pricing at $1.25 per million input tokens and $4.25 per million output tokens, while a contributor tier drew attention for especially low pricing. The report also noted skepticism. BridgeMind said recent AI launches have delivered surging benchmark numbers without matching gains in real-world experience. Artificial Analysis data cited in the article also showed weaker results for Muse Spark 1.3 in AA-Omniscience, where a higher abstention rate reduced hallucinations but pointed to limits in absolute knowledge gains.
