## Cerebrium

Cerebrium is serverless GPU infrastructure built specifically for real-time AI. Rather than asking teams to manage Kubernetes clusters or reserve GPU capacity in advance, it runs whatever container you point it at — LLM servers, voice pipelines, diffusion models, video generators — and takes care of provisioning, autoscaling, and routing. The platform emphasises low-latency startup: memory and GPU snapshots restore containers in roughly 2–4 seconds, compared with tens of seconds on conventional providers.

The company targets workloads where the first response is as important as the thousandth. Its own benchmarks and case studies cover voice agents responding in around 500 ms, deepfake detection at Resemble AI, AI-native web search at Linkup, digital humans at bitHuman and Tavus, and 50% lower inference costs at DistilLabs. Because cold starts dominate perceived quality in these products, Cerebrium treats startup time as a headline metric.

Under the hood it offers GPU types spanning Hopper and other generations across multiple clouds and regions, with pay-per-second billing so idle time is not charged. Bring-your-own-code deployment supports plain scripts, Dockerfiles, vLLM, SGLang, and Triton with TensorRT-LLM. Security controls include SOC 2 Type II, HIPAA, GDPR alignment, gVisor isolation, and regional data residency, and there is a free tier for trials in addition to paid usage.

**Pricing & Plans:** Free tier plus usage-based, pay-per-second billing on your chosen GPU hardware, with no reservations or long-term commitments. Exact rates are listed on the official pricing page.

- **Sub-second to low-second cold starts:** Memory and GPU snapshotting restores containers in roughly 2–4 seconds, which is essential for voice agents and other interactive workloads.
- **Elastic GPU capacity:** Access thousands of GPUs across 12+ GPU types and multiple clouds with no reservations or lock-in, scaling automatically on traffic bursts.
- **Bring your own code:** Deploy LLMs, voice pipelines, and image or video models from your own code or Dockerfile, with REST, WebSocket, and streaming endpoints.
- **End-to-end observability:** Real-time logs, metrics, and scaling events with native OpenTelemetry support for plugging into existing monitoring tools.
- **Compliance and isolation:** SOC 2 Type II, HIPAA, GDхPR, and ISO-aligned controls, gVisor isolation, multi-region failover, and regional data residency options.

**Strengths:** Snapshot-based restores cut cold starts to a few seconds, a real advantage for voice and interactive video; No Kubernetes to manage and no GPU reservations or capacity planning; Bring your own code or Dockerfile with no rewrites or proprietary SDK; Pay-per-second billing means idle resources are not billed

## OpenAI Platform

While ChatGPT serves end users, openai.com and the OpenAI Developer Platform (developers.openai.com) provide the foundational API, SDKs, and enterprise infrastructure powering thousands of production AI applications worldwide. In late 2026, OpenAI's API catalog is anchored by the GPT-6 and GPT-6.1 model suite—all featuring a 1.05-million-token context window and up to 128K output tokens. The lineup spans GPT-6 Astra for frontier reasoning and mission-critical research, GPT-6.1 Sol for near-Astra intelligence at one-fifth the price, GPT-6.1 Terra for fast visual reasoning and computer use, and GPT-6 Luna for ultra-high-volume, low-latency tasks, alongside specialized models like `gpt-5.3-codex` and `gpt-6-astra-law`.

The OpenAI Platform has evolved well beyond basic chat completion endpoints. Through the unified `v1/responses` API, developers can orchestrate stateful multi-step agents equipped with built-in server-side tools—including live web search, vector file search, code interpreter sandboxes, and GUI computer use—without stitching together external orchestration frameworks. Every flagship model supports configurable reasoning effort (`none`, `low`, `medium`, `high`, `xhigh`, and `max`), strict JSON schema Structured Outputs, and multimodal image/audio inputs, while `gpt-live-1` powers per-second billed speech-to-speech voice agents.

OpenAI bills API usage on a transparent consumption model scaled across usage tiers (Build, Launch, and Grow, scaling up to 40M+ tokens per minute). In 2026, aggressive price cuts on the 6.x generation dropped entry-level intelligence on GPT-6 Luna to $0.10 per million input tokens and $0.50 per million output tokens, while GPT-6.1 Sol runs at $2/$10 and flagship GPT-6 Astra sits at $10/$50. Engineering teams can cut spend by 90% on repeated context using automatic Prompt Caching, save 50% on asynchronous workloads via the Batch API, and enforce regional data residency with a 10% compliance uplift.

**Pricing & Plans:** Usage-based pay-per-token API billing: GPT-6 Astra at $10/1M input and $50/1M output tokens; GPT-6.1 Sol at $2/1M input and $10/1M output; GPT-6.1 Terra at $1/1M input and $5/1M output; GPT-6 Luna at $0.10/1M input and $0.50/1M output; GPT-Live-1 voice at $0.05/minute; 90% discount on cached inputs and 50% off via Batch API.

- **GPT-6 & GPT-6.1 Model Lineup with 1.05M Context:** Spanning GPT-6 Astra ($10/$50 per MTok), GPT-6.1 Sol ($2/$10), GPT-6.1 Terra ($1/$5), and GPT-6 Luna ($0.10/$0.50), all with a 1,050,000-token context window and 128K max output.
- **Configurable Reasoning Effort Controls:** Tune thinking token budgets per API request across six granularity levels (`none`, `low`, `medium`, `high`, `xhigh`, `max`) to balance latency, accuracy, and cost.
- **Responses API & Native Computer Use Tools:** Combine model inference with hosted web search, file search, function calling, and autonomous GUI computer-use actions in a single stateful API call.
- **GPT-Live-1 Realtime Voice API:** Build ultra-low-latency multimodal voice agents billed per second ($0.05/minute) without rounding up to whole minutes.
- **90% Prompt Caching Discount & Batch API:** Cached input tokens bill at just 10% of standard input rates, while asynchronous 24-hour Batch API jobs cut both input and output token costs by 50%.

**Strengths:** 100-fold cost flexibility from GPT-6 Luna ($0.10/$0.50 per 1M tokens) up to frontier GPT-6 Astra ($10/$50 per 1M tokens); Unified 1.05M-token context window and 128K output limit across the entire flagship GPT-6 and GPT-6.1 family; 90% discount on cached input tokens and 50% Batch API discount dramatically reduce production inference bills; Industry-standard SDKs, Structured Outputs, and built-in Responses API tools minimize boilerplate agent code

**Limitations:** Long-context requests exceeding the standard window threshold trigger roughly 2x higher per-token billing rates; Flagship GPT-6 Astra ($10 input / $50 output per 1M tokens) is significantly more expensive than Claude Opus 5.5 ($4/$20) and Grok 4.7 ($2/$6); Regional data residency endpoints incur a 10% price uplift on models released after March 2026
