What happened

Between the Sep 21, 2026 and Sep 28, 2026 captures of Fireworks' pricing page, Pulse recorded one change: Fireworks added GLM 5.3 Flash as a new base model in the Serverless Training API pricing table, with its own 200K context window and per-1M-token pricing for prefill, cached prefill, sample, and train. Pulse files it as a packaging change (new add-on). 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).

It lands 12 days after Fireworks' previous change, "Fireworks adds GLM 5.3 to Serverless Training at $14.58/1M train tokens" (Sep 16, 2026). Before that Pulse recorded "Fireworks adds DeepSeek V4 Flash, Muse Glimmer 30B to training API" (Sep 1, 2026), "Fireworks: On-Demand GPU pricing up 11-30% from Sep 1; region surcharge to 1.5x" (Aug 17, 2026) and "Fireworks: New GB300 GPU tier ($18/hr) + region premium pricing" (Aug 11, 2026). Fireworks has been tracked since 2024-11-17.

In the same window Corel, 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.
