What happened

Between the Aug 31, 2026 and Sep 7, 2026 captures of Fireworks' pricing page, Pulse recorded one change: Serverless Training API model catalog updated: Qwen 3.5 9B (64k, $0.66 prefill) removed and Qwen 3.6 27B replaced by Qwen 3.8 27B at identical pricing; DeepSeek V4 Flash 0731 (262K) and Muse Glimmer 30B (128K) added with per-token prefill/cached/sample/train pricing. Pulse files it as a product change (feature change). Pulse's latest capture (Nov 15, 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).

This weekly roll-up includes the change Pulse first recorded in a shorter period: "Fireworks adds DeepSeek V4 Flash, Muse Glimmer 30B to training API" (Day 244, 2026, saved Sep 1, 2026). It is the same change, not a new one. Before that, Fireworks' previous recorded change was "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.

In the same window Figma, Sketch and Adobe also changed their Marketing & Content pricing pages. Those moves are listed further down, and the Pulse Agent can compare them side by side.
