Fireworks: new Serverless Training API for pay-per-token LoRA training
What happened
Between the Jul 27, 2026 and Jul 28, 2026 captures of Fireworks's pricing page, Pulse recorded one change: New Serverless Training API section added — pay-per-token LoRA training (no provisioning/idle cost) for Qwen 3.5 9B, Qwen 3.6 27B, and Kimi K3, priced per prefill/cached-prefill/sample/train tokens. In detail: Fireworks launched a new Serverless Training API: pay-per-token LoRA training (no provisioning/idle cost) for Qwen 3.5 9B, Qwen 3.6 27B, and Kimi K3, priced per prefill/cached-prefill/sample/train tokens. Pulse files it as a packaging change (new add-on) with an upward direction. Pulse's latest capture (Oct 19, 2026) lists On-Demand at $13 per GPU hour (B200 180GB) + $15 per GPU hour (B300 288GB), Serverless at $0.08 per 10M input tokens (embeddings, up to 150M params) + $0.16 per 10M input tokens (embeddings, 150M-350M params) and Fine Tuning at $0.5 per 1M training tokens, LoRA SFT (models up to 16B params).
It lands 14 days after Fireworks's previous change, "Fireworks: On-Demand GPU pricing increased, new B300 tier added" (Jul 13, 2026). Before that Pulse recorded "Fireworks renames Serverless tier from Turbo to Fast" (Jun 8, 2026), "Fireworks hikes GPU prices, moves model pricing behind docs wall" (May 12, 2026) and "Fireworks adds DeepSeek-V4-Pro at $3.48/1M tokens, drops speech and image tiers" (May 4, 2026). Fireworks has been tracked since 2024-11-17.
In the same window Sketch, Adobe and Corel also changed their Marketing & Content pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
