What happened

Between the Sep 15, 2026 and Sep 16, 2026 captures of Fireworks's pricing page, Pulse recorded one change: Added GLM 5.3 model (262K context) to the Serverless Training API pricing table: $4.86 prefill/1M, $0.972 cached prefill/1M, $12.15 sample/1M, $14.58 train/1M tokens. Pulse files it as a product change (feature added) with an upward direction. Pulse's latest capture (Oct 26, 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 9 days after Fireworks's previous change, "Fireworks rebuilds Serverless Training API catalog: drops Qwen 3.5 9B, adds DeepSeek V4 Flash and Muse Glimmer 30B" (Sep 7, 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.
