Fireworks adds DeepSeek V4 Flash, Muse Glimmer 30B to training API
What happened
Between the Aug 31, 2026 and Sep 1, 2026 captures of Fireworks's pricing page, Pulse recorded one change: Serverless Training API catalog updated: removed Qwen 3.5 9B, renamed Qwen 3.6 27B to Qwen 3.8 27B (same pricing), and added DeepSeek V4 Flash 0731 and Muse Glimmer 30B with new per-token pricing. Pulse files it as a product change (feature added) 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 15 days after Fireworks's previous change, "Fireworks: On-Demand GPU pricing up 11-30% from Sep 1; region surcharge to 1.5x" (Aug 17, 2026). Before that Pulse recorded "Fireworks: New GB300 GPU tier ($18/hr) + region premium pricing" (Aug 11, 2026), "Fireworks: New Serverless Training API added (Qwen 3.5 9B, 3.6 27B, Kimi K3)" (Aug 5, 2026) and "Fireworks: new Serverless Training API for pay-per-token LoRA training" (Jul 28, 2026). Fireworks has been tracked since 2024-11-17.
