Inference Serverless pricing update: DeepSeek V4.1 Flash On October 1, 2026 at 00:00 UTC , serverless pricing for DeepSeek V4.1 Flash changes (uncached input / cached input / output price per 1M tokens): Standard: $0.22 / $0.007 / $0.66 → $0.30 / $0.006 / $1.20 Priority: $0.275 / $0.00875 / $0.825 → $0.375 / $0.0075 / $1.50 This adjustment brings our pricing in line with current market rates for this model. It applies only to serverless usage. If you run DeepSeek V4.1 Flash on a dedicated deployment or use Reserved Throughput, your pricing is unaffected. We are also rolling out infrastructure improvements designed to improve cache hit rate, minimize cost per task, and deliver a faster, more reliable experience across the board. See Serverless pricing for the full rate card.

Platform New deployment creation flags: deploymentShape: "default" and acceptShapelessRisk Two new options are available on the Create Deployment API, in firectl ( --deployment-shape default / --accept-shapeless-risk ), and in the Python SDK ( deployment_shape="default" / accept_shapeless_risk=True ): deploymentShape: "default" — Fireworks picks a validated deployment shape for the model and creates the deployment from it. If every compatible shape conflicts with fields in your request, the request fails with an error naming the conflicting fields and compatible shapes; the pick never silently overrides your settings or falls back to creating without a shape. acceptShapelessRisk=true — an explicit opt-out that creates the deployment without a shape, preserving current behavior. It cannot be combined with a shape. Deployments created without a shape skip shape validation and are the most common cause of failed deployment creations. Enforcement is coming soon: shapeless creation will then require the explicit opt-in, so start passing a shape (or default ) now. The opt-out is for advanced users only. If you have a workload no existing shape covers, contact us and we’ll help you find or add one.

Gemini 3.8 Live and Gemini 3.8 Live Extended Thinking generally available (GA): Released two new audio-to-audio models for real-time voice applications using the Live API: Gemini 3.8 Live ([gemini-3.8-live](/gemini-api/docs/models/gemini-3.8-live)): The default option for most low-latency voice agent experiences and real-time dialogue without reasoning delays. Features interleaved reasoning, default asynchronous function calling, and full session client content updates. Gemini 3.8 Live Extended Thinking ([gemini-3.8-live-extended-thinking](/gemini-api/docs/models/gemini-3.8-live-extended-thinking)): High-reasoning audio-to-audio model supporting background reasoning during live audio interactions, recommended when higher background reasoning is required. To get started, see the [Live API guide](/gemini-api/docs/live-api), the [Capabilities guide](/gemini-api/docs/live-api/capabilities), and the [Thinking guide](/gemini-api/docs/live-api/thinking).
Rollouts for dedicated model inference Rollouts shift live traffic from one deployment to another under the same endpoint, without changing the endpoint URL. Pick a canary, blue-green, or rolling strategy to determine how traffic moves, and optionally gate a canary rollout on live metrics so it pauses automatically if the new deployment regresses. Start a rollout with the tg beta endpoints rollout CLI command or from the endpoint’s Rollouts tab in the console, then pause, resume, promote, or cancel it at any point while it runs. Together CLI v2.34.0 Version 2.34.0 of the Together CLI and Python SDK carries the rollouts release above (the SDK surface is client.beta.endpoints.rollouts ) and also adds: HIPAA placement : tg beta endpoints deploy accepts --placement.hipaa to restrict a deployment to HIPAA-attested clusters. The Python SDK takes the same policy as compliance_policy on inline placement. tg files check now rejects Parquet files larger than the maximum supported file size instead of passing them through format validation. See the CLI reference .

15 SIGNALSThe Messages API can now compact a conversation on demand on the Claude API, in beta with the compact-2026-09-04 beta header. Send the top-level compaction parameter, and the API returns a signed compaction block that summarizes the messages you sent. On later requests, send that block first, in place of those messages. You choose when to compact, the request can run in the background, and you can keep recent turns word for word after the summary. On models with preserved thinking, the thinking in those kept turns can stay valid.

Inference Upcoming Serverless deprecation: older DeepSeek, GLM, Muse, and Kimi models Several older Serverless models will be decommissioned on September 25, 2026 to better serve newer, higher-performance replacements. This applies only to serverless endpoints , including Fast and US-only Serverless endpoints for models that have those variants. Dedicated deployments are unaffected. Action required If you use any of the models below on serverless, migrate to a recommended replacement before September 25, 2026 . After that date, they will no longer be available via serverless endpoints. Recommended migrations DeepSeek V4 Flash (0731) — migrate to DeepSeek V4.1 Flash DeepSeek V4 Pro (0813) — migrate to DeepSeek V4.1 Flash DeepSeek V4 Flash Vision Exp — migrate to DeepSeek V4.1 Flash GLM 5.2 — migrate to GLM 5.3 Muse Glimmer 30B — migrate to NVIDIA Nemotron 3.5 Lightning 30B A3B Kimi K2.6 — migrate to GLM 5.3 or Kimi K3 Kimi K2.7 Code — migrate to GLM 5.3 or Kimi K3 On official benchmarks, DeepSeek V4.1 Flash outperforms DeepSeek V4 Pro (0813). DeepSeek V4.1 Flash is also multimodal, with the same vision capability as DeepSeek V4 Flash Vision Exp. If you want to switch to a dedicated deployment, see the Serverless model list and the on-demand deployment quickstart .

API changes DeepSeek V4.1 Flash is now available on the DeepSeek API with native multimodal support. Change the model name to deepseek-flash to call the latest V4.1 Flash model. The previous-generation models V4 Flash and V4 Flash Vision Exp have been retired; for compatibility, the model names deepseek-v4-flash and deepseek-v4-flash-vision-exp are temporarily routed to V4.1 Flash. In response to user demand, we have decided to continue providing API services for DeepSeek V4 Pro after September 14, 2026, with the billing method remaining unchanged. We will provide further notice should there be any changes. Thank you for your understanding and support! API pricing adjustment With the release of DeepSeek-V4.1-Flash, API prices have been reduced accordingly. For details, please refer to Models & Pricing.
