Fireworks adds GLM 5.3 Flash with 200K context, per-token training pricing
What happened
Between the Sep 21, 2026 and Sep 28, 2026 captures of Fireworks's 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) 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 12 days after Fireworks's previous change, "Fireworks adds GLM 5.3 to Serverless Training at $14.58/1M train tokens" (Sep 16, 2026). Before that Pulse recorded "Fireworks rebuilds Serverless Training API catalog: drops Qwen 3.5 9B, adds DeepSeek V4 Flash and Muse Glimmer 30B" (Sep 7, 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.
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.
