Fireworks adds Muse Spark Open, DeepSeek V4.1 Flash to Serverless Training
What happened
Between the Oct 16, 2026 and Oct 17, 2026 captures of Fireworks' pricing page, Pulse recorded one change: Serverless Training API table adds Muse Spark Open (256K; $6.19 prefill, $15.48 sample, $18.58 train) and DeepSeek V4.1 Flash (256K; $0.60 prefill, $3.60 sample, $4.98 train) per 1M tokens. Pulse files it as a product change (feature added). Pulse's latest capture (Nov 14, 2026) lists Serverless at $0.08 per 10M input tokens (embeddings, up to 150M params) + $0.16 per 10M input tokens (embeddings, 150M-350M params), Fine Tuning at $0.50 per 1M training tokens, LoRA SFT (models up to 16B params) and On-Demand at $13 per GPU hour (B200 180GB) + $15 per GPU hour (B300 288GB).
It lands 19 days after Fireworks' previous change, "Fireworks adds GLM 5.3 Flash with 200K context, per-token training pricing" (Sep 27, 2026). Before that Pulse recorded "Fireworks adds GLM 5.3 to Serverless Training at $14.58/1M train tokens" (Sep 16, 2026), "Fireworks adds DeepSeek V4 Flash, Muse Glimmer 30B to training API" (Sep 1, 2026) and "Fireworks: On-Demand GPU pricing up 11-30% from Sep 1; region surcharge to 1.5x" (Aug 17, 2026). Fireworks has been tracked since 2024-11-17.
