Iterate.ai says its Lifeboat inference engine can fit two to six times as many concurrent AI agent sessions on a GPU, but the published test supports a narrower result: twice as many sessions as the same engine with its optimizations turned off. That company-run test used one NVIDIA RTX PRO 6000 Blackwell GPU and Qwen 30B-A3B; it was reported by SiliconANGLE on October 5, 2026, and was not independently verified.
What did the Lifeboat benchmark show?
In Iterate.ai’s reported test, Lifeboat handled 2,048 concurrent sessions on one NVIDIA RTX PRO 6000 Blackwell GPU running Qwen 30B-A3B. With Lifeboat’s optimizations disabled, the same engine handled half as many—1,024 sessions, derived from the report’s comparison. Throughput was 8,714 tokens per second with the optimizations on and 4,965 with them off. SiliconANGLE reported these figures from Iterate.ai’s testing; they are not independent measurements. SiliconANGLE’s October 5, 2026 report describes the setup and results.
| Reported measure | Lifeboat optimizations on | Same engine, optimizations off |
|---|---|---|
| Concurrent sessions on one RTX PRO 6000 Blackwell running Qwen 30B-A3B | 2,048 | 1,024 (half of 2,048, derived from the report) |
| Throughput in that test | 8,714 tokens per second | 4,965 tokens per second |
The report also describes a separate memory-pressure test with 128 concurrent sessions making 18,000-token requests. In that workload, the reported 99th-percentile time to first token was 1.5 seconds with Lifeboat and 189 seconds with the baseline. The comparison is again against Lifeboat with its optimizations disabled, not another vendor’s inference engine.
Does the test verify the “up to six times” claim?
No. Iterate.ai’s broader claim is two to six times as many concurrent sessions per GPU. The published session-density comparison shows a twofold increase on the specified hardware and model, against Lifeboat itself with optimizations turned off. The report does not provide an independently verified benchmark or conditions demonstrating the six-times maximum. Treat six times as a company claim, not as an established result for every GPU, model, or workload.

How does Lifeboat try to fit more agent sessions?
Iterate.ai says agent workloads can make many model calls within one task, causing each session’s growing context to consume GPU key-value (KV) cache. When memory is constrained, that cache can limit how many requests run at once. The company says conventional inference engines may stall with four or five long-context requests running simultaneously; that characterization is attributed to Iterate.ai in the launch report, not an independently measured finding.
The reported Lifeboat design combines several mechanisms:
Rank #2
- NVIDIA Volta GV100 Architecture — 4,608 CUDA Cores, 640 1st-Gen Tensor Cores delivering 14 TFLOPS FP32 and 112 TFLOPS deep learning performance for AI training, inference, HPC, and scientific computing workloads
- 32GB HBM2 ECC Memory — 900 GB/s Bandwidth — High-bandwidth memory on a 4096-bit bus with ECC error correction provides the memory capacity and throughput required for the largest AI models, simulations, and datasets
- PCIe 3.0 x16 Interface — 250W TDP — Standard PCIe Gen3 connectivity with passive cooling designed for enterprise rack server deployment in HPE ProLiant, Dell PowerEdge, and Supermicro platforms with adequate chassis airflow
- NVLink — Scale to 96GB Unified Memory — Connect two V100 GPUs via NVLink at 300 GB/s bi-directional bandwidth to scale GPU memory from 32GB to 96GB for larger AI training and HPC workloads
- Multi-Precision Computing — Supports FP64 (7 TFLOPS), FP32 (14 TFLOPS), FP16 (112 TFLOPS) and INT8 precision modes for flexible deployment across training, inference, and scientific simulation workloads
- Fair scheduling and admission control: manage which requests run and when new sessions are accepted.
- KV-cache optimization: Iterate.ai says this can double effective cache capacity while retaining full-precision model weights.
- Selective mixture-of-experts loading: load components of a mixture-of-experts model selectively rather than keeping every component active.
- Per-session controls: use security capsules with filtering, token budgets, and sandboxed execution.
These are product capabilities and effects described by Iterate.ai in the launch report; the reported benchmark does not isolate how much each mechanism contributed to the results.
What does the Confidential Computing edition add?
SiliconANGLE reported a separate Confidential Computing edition. According to the report, it waits for hardware attestation before serving requests, checking trusted-execution features in AMD and Intel processors and NVIDIA confidential-computing mode on the H100, B200, GB300, and other supported GPUs. The report says model weights remain encrypted in use inside a trusted execution environment, either in a cloud confidential VM or on customer-owned hardware. These are features as described by Iterate.ai, not independently assessed security guarantees.

What licenses and prices were reported?
SiliconANGLE reported on October 5, 2026 that Lifeboat was generally available and listed the following terms. Software licensing and availability can change, so confirm current terms with Iterate.ai before deciding.
| License | Reported terms |
|---|---|
| Developer | Free for noncommercial and evaluation use on up to two inference servers on one node. |
| Standard | $49.99 per month; seven-day trial without a credit card reported. |
| Confidential Computing | $499.99 per month; seven-day trial without a credit card reported. |
These are terms reported by SiliconANGLE on October 5, 2026, not a guarantee that the same prices or trial conditions remain available.
How should teams evaluate the capacity claim?
The published result is a useful starting point for a test plan, not a substitute for testing a team’s own workload. Session density depends on the model, GPU, context length, request mix, and the definition of a successful session. For a meaningful comparison, keep those conditions consistent and record:
- GPU model and memory, model and precision, and inference-engine configuration.
- Prompt and context lengths, output lengths, and the number of concurrent sessions.
- Throughput and latency, including time to first token and tail latency.
- Output quality, errors or failed requests, and whether the system sustains the load.
- Whether the baseline is another engine or the same engine with selected optimizations disabled.
That last distinction matters here: the published 2,048-session result compares Lifeboat’s optimized and unoptimized configurations, not Lifeboat against a competing product.
