What changed
Baseten's Model APIs catalog gained two new entries: Reflection Beam, priced at $1.30 per 1M input tokens, $0.13 for cached input, and $4.30 for output; and Meta Muse Spark Open, at $1.25 input, $0.15 cached, $4.25 output. Both join Baseten's existing model lineup as pay-per-token, instant-access options with a "Try Model API" link.
Why it matters
For teams comparing inference providers on price and model breadth, Baseten's two-new-models-in-two-days pace is worth tracking against its typical ~21-day gap between changes. Watch whether Baseten keeps this faster cadence or returns to its historical pace once the current wave of catalog additions settles.
In context
This is Baseten's second model-catalog addition in two days, coming right after Nemotron 3.5 Super VL was added at $0.20 per 1M input tokens on Oct 16 — a sharp acceleration from its typical ~21-day gap between changes. Baseten's other recent moves in this pattern include a 77% cut to DeepSeek V4.1 Flash's cached input price in September and Kimi K3's addition in July. Market-wide, 201 pricing changes across 153 companies have touched credits-and-usage billing in the last 180 days, 11.6% of everything tracked.
What people are saying
“Muse Spark Open costs $0.84 per Intelligence Index task at current API pricing of $1.25/$4.25 per 1M input/output tokens ($0.15 cached input) from Together AI, Fireworks and Baseten - less than half of GLM-5.3 (max, $2.01), but about three times DeepSeek V4.1 Flash (max, $0.27)”
View original“Day one. 7 clouds. One price war. Meta's Muse Spark Open didn't just drop weights yesterday — it launched on 7 inference clouds on day one (Baseten, Fireworks, Groq, Modal, Nebius, OpenRouter, Together AI) plus 4 weight channels (Hugging Face, SageMaker, Model Garden, Foundry). Day-one API price (Together): $1.25/1M input, $4.25/1M output, $0.15/1M cached. The twist: against Kimi K3 ($3/$15), the US open model is suddenly the cheap one — ~$0.84/task vs $2.00 per one index. For years the cost edge ran toward Chinese labs. This pair inverts it. Honest footnote: those prices are a day-one snapshot — all inference goes through third parties, so they'll move as providers compete. The license caps cloud resellers at $20M before Meta wants a deal. The weights were free. The race is over who bills you less to run them.”
View original“Together AI made Muse Spark Open free through Oct 18 (list $1.25 in / $4.25 out per 1M tokens) and added Nemotron 3.5 Super VL at $0.15 / $0.50. @togethercompute: how does this compare with @FireworksAI_HQ and @baseten?”
