Lambda Labs vs DeepInfra: open-weight inference (2026)

Lambda Labs and DeepInfra both serve open-weight LLM inference, but the businesses around the API are very different. Lambda Labs is GPU-cloud-first with an LLM API on top; DeepInfra is purpose-built around the cheapest possible open-weight inference. Below: a head-to-head on the dimensions that matter when you ship.

Pick Lambda Labs or DeepInfra?

When to choose Lambda Labs

Choose Lambda Labs when you want a single vendor for both LLM inference and raw GPU rental — for example, training or fine-tuning on rented H100/H200 then serving the result. Lambda has built reputation in the GPU-cloud space first; the inference API is a clean extension. For teams that need raw compute (Lambda hourly H100s) plus a hosted Llama endpoint, the unified bill is operationally simpler.

  • GPU cloud + LLM API under one vendor
  • Direct H100 / H200 hourly rental for self-hosting or training
  • Competitive shared-tier per-token pricing
  • Operationally simpler for hybrid train + serve setups
  • Trusted GPU-cloud reputation from the AI research community

When to choose DeepInfra

Choose DeepInfra when the lowest possible per-token price on open-weight LLMs is the priority. DeepInfra has positioned itself around ultra-cheap inference — Llama 3.3 70B is commonly $0.20-0.60 per 1M tokens, materially cheaper than Together, Fireworks, or Lambda. For high-volume batch workloads (classification, summarisation, RAG over large corpora) this can cut the inference bill by 50% or more.

  • Among the cheapest per-token rates for open-weight LLMs
  • Llama 3.3 70B typically $0.20-0.60 per 1M tokens
  • Broad catalogue of open-weight models (100+)
  • Strong fit for batch and high-volume workloads
  • OpenAI-compatible API with no markup model

Run Lambda Labs and DeepInfra side-by-side

VerticalAPI lets you switch between Lambda Labs and DeepInfra per-request through a single OpenAI-compatible endpoint. Use Lambda when you also need raw GPU rental or a single vendor for train + serve; use DeepInfra for the cheapest per-token batch inference. Same SDK, same API key, zero markup — you pay Lambda Labs and DeepInfra directly with your own keys (BYOK).

from openai import OpenAI
client = OpenAI(base_url="https://api.verticalapi.com/v1", api_key="vapi_...")

# Lambda Labs — LLM API + GPU rental in one place
resp_x = client.chat.completions.create(

VerticalAPI verdict

Use Lambda Labs when you want a single vendor for LLM inference plus raw GPU rental, or when train + serve under one bill matters. Use DeepInfra when raw per-token cost on high-volume open-weight workloads drives the decision. Through VerticalAPI you can route between both with a single OpenAI-compatible endpoint and BYOK — no SDK migration.

Frequently asked questions

Is DeepInfra cheaper than Lambda Labs for Llama 3.3 70B?

Usually yes. DeepInfra commonly prices Llama 3.3 70B in the $0.20-0.60 per 1M tokens range in 2026, while Lambda Labs sits in the more typical $0.60-1 mid-market band. For batch and high-volume workloads (millions of tokens per day), DeepInfra can cut the inference bill by 50% or more. The trade-off is fewer adjacent offerings like raw GPU rental.

Can I rent raw GPUs from either?

Lambda Labs is a GPU cloud first — direct H100 / H200 hourly rental is the core product. DeepInfra is inference-only; there is no raw GPU rental. For teams that need to train or fine-tune on rented GPUs and then serve via API, Lambda is the natural unified-bill choice. DeepInfra is purely an inference provider.

Which has a broader catalogue?

DeepInfra. DeepInfra hosts 100+ open-weight models across Llama, Mistral, Qwen, DeepSeek, and more. Lambda's LLM API catalogue is narrower and focused on the most popular Llama, Mistral, and Qwen variants. For niche open-weight models, DeepInfra is more likely to host them at low cost.

Which is faster?

Both providers are competitive on shared multi-tenant inference for hot models like Llama 3.3 70B. DeepInfra has invested heavily in inference optimisation to support ultra-cheap pricing without latency penalties; Lambda's shared LLM tier is solid but not specifically tuned for the lowest possible TTFT. For latency-critical workloads, benchmark both on your traffic.

Can I call both Lambda Labs and DeepInfra through one endpoint?

Yes. VerticalAPI exposes a single OpenAI-compatible endpoint at https://api.verticalapi.com/v1. You send the same request shape and change the model parameter (for example, lambdalabs/llama-3.3-70b or deepinfra/llama-3.3-70b) and the matching X-Provider-Key header. There is no markup on tokens; you pay Lambda Labs and DeepInfra directly using your own keys (BYOK).

Limitations of this comparison

  • Per-token pricing for open inference changes frequently — DeepInfra's $0.20-0.60 figure is a mid-2026 range, not a guarantee.
  • Lambda Labs' GPU-cloud and LLM-API businesses have different SLAs and quota structures that can be confusing.
  • Ultra-low DeepInfra prices may come with stricter rate limits and noisy-neighbour effects at peak times.
  • Catalogue coverage shifts as new models drop; benchmark availability of specific Llama / Qwen variants before committing.
  • This page covers two of several open-inference providers. Together AI, Fireworks, Replicate, and Lepton all overlap.

What may change in 12-24 months

  1. DeepInfra is likely to keep pushing per-token prices down — $0.15 per 1M tokens for Llama 3.3 70B is plausible by late 2026.
  2. Lambda Labs is expected to expand the LLM API tier and integrate it more tightly with their GPU-cloud reservations.
  3. Catalogue parity between providers will narrow as new open-weight releases ship simultaneously on all major hosts.
  4. Provider lock-in will weaken further as OpenAI-compatible gateways (including VerticalAPI) make swapping open-inference providers a one-line change.
