SubQ launches 12M-token SSA model with SubQ Code early access

SubQ launched a sub-quadratic sparse-attention model with a 12 million token context window and opened early access alongside SubQ Code. The company claims 52x faster 1M-token performance than FlashAttention and under 5% of Opus cost, putting long-context coding workflows into a new price and latency band.
