What changed
Baseten cut per-1M-token rates for its Reflection Beam Model API: input from $1.30 to $0.40, cached input from $0.13 to $0.04, and output from $4.30 to $1.20 - up to 72% off the launch rates. Reflection Beam was added to Baseten's Model APIs catalog on Oct 17, 2026 alongside Meta Muse Spark Open, at those same $1.30/$0.13/$4.30 launch prices now being cut.
Why it matters
For buyers evaluating Baseten's Model APIs, the lesson is that launch-day rates aren't necessarily the floor - Reflection Beam's price has already moved since it was added to the catalog. Watch whether this cut holds or Baseten keeps adjusting individual model rates as usage and competitor pricing shift; the company has been changing its pricing roughly every 15 days since Jul 20, 2026, and this catalog looks likely to keep moving.
In context
Baseten added Reflection Beam to its Model APIs lineup on Oct 17, 2026 at $1.30 input, $0.13 cached input and $4.30 output per 1M tokens, alongside Meta Muse Spark Open. Those launch rates are already gone: this diff cuts them to $0.40, $0.04 and $1.20. Baseten made a similar move on DeepSeek V4.1 Flash, cutting its cached-input price 77% to $0.007 per 1M tokens on Sep 22, 2026, and this cut lands 3 days after Baseten added DeepSeek V4.1 Flash 1017 at $0.30 input, $1.20 output. Usage-based pricing is common across the index: 241 changes across 175 companies touched credits and usage billing in the last 180 days.
