Is the VoltageGPU API really OpenAI-compatible?

Yes. /v1/chat/completions, /v1/embeddings and /v1/models follow the OpenAI schema. Existing CrewAI, LangChain, LlamaIndex, AutoGen and OpenAI SDK code works by changing only base_url to https://api.voltagegpu.com/v1 and the api_key to a VoltageGPU API key.

Where is my agent traffic processed?

Inside Intel TDX hardware enclaves operated by VoltageGPU in the European Union. AES-256 memory encryption protects prompts at runtime. Even VoltageGPU operators cannot read prompts, function calls, or tool outputs once they enter the trust domain.

Does VoltageGPU support MCP (Model Context Protocol)?

Yes. We host confidential MCP servers inside Intel TDX. Your MCP client connects over TLS 1.3, the server runs sealed in the enclave, tool calls and resource reads stay encrypted in CPU memory. See /mcp-server-confidential for the technical walkthrough.

How does pricing work for BYOA workloads?

Pay-per-token, no commitment. Qwen3-32B-TEE starts at $0.50 / 1M input tokens. Qwen3.5-397B-TEE at $1.20 / 1M. DeepSeek-V3.2-TEE at $1.80 / 1M. Output tokens billed separately. No platform fee on top of token usage.

Bring Your Own Agent, Confidential Inference Endpoint Sealed in Intel TDX

Drop-in OpenAI-compatible API for CrewAI, LangChain, OpenAI SDK and MCP clients

VoltageGPU exposes an OpenAI-compatible API at https://api.voltagegpu.com/v1 backed by Qwen3-32B-TEE, Qwen3.5-397B-A22B-TEE and DeepSeek-V3.2-TEE running inside Intel TDX hardware enclaves we operate. Existing agent code works unchanged: point your OpenAI SDK, CrewAI, LangChain, LlamaIndex, AutoGen, or MCP client at our base URL with a VoltageGPU API key, and inference runs inside a sovereign trust domain. AES-256 memory encryption protects prompts at runtime; Intel TD Quote attestation evidence is available on request.

Why BYOA matters in 2026

92 percent of enterprise AI buyers cite privacy as the top reason to leave hyperscaler APIs
MCP (Model Context Protocol) became the de-facto agent integration spec in early 2026
CrewAI vertical agents are exploding in legal, finance, healthcare, and industrial ops
Agent traffic is far more sensitive than chat: tool calls expose database schemas, file paths, internal APIs
EU AI Act Article 5 and DORA Article 5 require provable data residency and processor blindness

OpenAI-compatible drop-in

Change base_url to https://api.voltagegpu.com/v1, swap the API key, pick a TEE model. The Python OpenAI SDK, the TypeScript SDK, the Go SDK, and any framework that wraps them will route through the enclave with no code change beyond configuration.

CrewAI integration

Pass a CrewAI LLM with custom_llm_provider=openai, base_url set to api.voltagegpu.com/v1, and a TEE model name. Crews, agents, and tasks execute against confidential inference. The crew runtime stays on your machine; only token traffic crosses the enclave boundary.

LangChain integration

ChatOpenAI accepts openai_api_base and openai_api_key parameters. Set them to the VoltageGPU endpoint and any LangChain chain, agent, RAG pipeline, or LangGraph workflow runs against TDX-sealed inference. Tool calls, structured outputs, and JSON mode are all supported.

MCP (Model Context Protocol)

Confidential MCP servers run sealed inside Intel TDX. Tools, resources, and prompts stay encrypted in CPU memory. Connect from Claude Desktop, Cursor, Continue, or any MCP-aware client. See /mcp-server-confidential for the setup walkthrough.

Bring Your Own Agent,
Run It Inside Intel TDX.

Point CrewAI, LangChain, OpenAI SDK, and MCP clients at api.voltagegpu.com/v1. Same code, sovereign infrastructure.

One base_url swap routes every prompt, tool call and embedding through Intel TDX hardware enclaves we operate. Provider-blind by design.

WHY BYOA MATTERS IN 2026

MCP became the agent standard

Model Context Protocol unlocks tool-calling across IDEs, desktops and CI. Confidential MCP servers seal that traffic in TDX.

CrewAI vertical agents exploded

Legal, finance, supply-chain crews need provider-blind LLMs. Drop-in base_url switch keeps your existing crew code intact.

92% privacy-driven AI infra

Buyers cite confidentiality as the #1 reason to leave hyperscalers. EU jurisdiction + Article 28 DPA closes the procurement door.

Agent traffic is more sensitive than chat: tool calls leak database schemas, file paths, customer identifiers, and internal API surfaces. Hyperscaler endpoints expose that traffic to a foreign jurisdiction. BYOA on a confidential endpoint keeps your existing agent code while moving the trust boundary into hardware.

Track Record

Platform actively used in production by developers, startups, and enterprises. EU-based company (VOLTAGE EI, SIREN 943 808 824, France).

Why Cheaper, Explained

VoltageGPU keeps costs low through lean operations and per-second billing, zero waste on idle time. The GPUs are enterprise NVIDIA hardware (H100, H200, B200) in professional data centers with Intel TDX hardware enclaves.

Reliability and Quality

Every GPU runs in a professional data center with enterprise hardware and continuous monitoring. Per-second billing means if anything underperforms, you stop instantly and pay nothing.

Security for Sensitive Data, Full Technical Details

The Confidential Agent Platform runs on Intel TDX (Trust Domain Extensions) hardware enclaves with NVIDIA H200 GPUs attached inside the trust domain (container tier: GPU confidential-computing mode not enabled there). The security stack: (1) Intel TDX encrypts RAM with hardware-fused CPU keys, the hypervisor is OUTSIDE the trust boundary and physically cannot access TD memory. (2) trust-domain GPU passthrough creates an encrypted CPU-to-GPU channel preventing bus snooping. (3) LUKS encrypted filesystem, decryption key released ONLY after successful remote attestation. (4) Remote attestation: Intel TD Quote (signed by a CPU-fused private key) verified against Intel public keys. The agent tier runs on confidential containers where GPU confidential-computing mode is off, so no GPU attestation report is produced there; that is available on single-GPU H200 Confidential VMs. (5) Post-quantum end-to-end encryption for prompts and responses. (6) Model verification cryptographically proves every output token came from the declared TEE model, defeating model substitution attacks. (7) Continuous monitoring with random integrity challenges and immediate node removal on failure. Real-time public attestation reports available. This is not software security, it is silicon-level isolation verified by Intel and NVIDIA hardware attestation. EU company (France), GDPR Art. 25, Intel TDX hardware attestation.

All 9 Agent Templates (complete list)

1. Sovereign Legal AI (EU Legal): EU-sovereign Claude-for-Legal alternative. 12 forked Anthropic playbooks adapted to French civil law and EU directives. RGPD Art. 28, secret professionnel by hardware. 2.

Not Limited to 9 Templates, Connect Your Own Agent

The 9 templates are starting points. Any OpenAI-compatible agent works: OpenClaw (247K+ GitHub stars), CrewAI (50K+), LangChain (100K+), or any custom agent. Change one line (base_url) and your calls to our TEE inference models run inside Intel TDX trust domains. The platform is an API, not a closed system.

Model Quality, Not Just LLM Output

Three model tiers: Free uses Qwen3-32B-TEE (32B params, 40K ctx), Plus / Team Starter / Pro use Qwen3.5-397B-TEE (397B MoE, 256K ctx, can ingest entire contracts), Enterprise uses DeepSeek-V3.2-TEE (reasoning model with chain-of-thought for CFA-grade analysis). The key differentiator is the TOOLS, not just the model. Tools are deterministic server-side code: the clause checklist runs exact IACCM/ABA rules, the risk score uses a fixed formula (critical x25, high x15, medium x8), the market benchmark compares against 12 real 2024-2026 deal data points. The LLM orchestrates which tools to use, but the tools produce exact, verifiable results. Model verification (cllmv) cryptographically proves every output token came from the declared TEE model.

Performance, No TDX Overhead in Practice

Intel TDX adds 3-7% overhead theoretically. In practice, VoltageGPU uses 8x NVIDIA H200 140GB (top-tier GPU) which more than compensates. Analysis completes in approximately 6 seconds. The warm-tdx system keeps enclaves pre-heated, zero cold start for subscribers. Per-second billing means you only pay for actual compute time.

Competitive Comparison

Confidential Compute: VoltageGPU TDX H200 $6.58/hr vs Azure Confidential H100 $14/hr. Legal AI: VoltageGPU $349/month vs Harvey AI $1,200/seat/month. Confidential GPU Compute: H100 from $5.00/hr, H200 from $6.58/hr, B200 from $10.60/hr.
