Parasail vs Relace: key differences
Relace builds utilities for coding agents. relace-apply-3 merges edits at about 10,000 tokens per second with 128K tokens of input and output, Relace's compaction model runs at 50,000 tokens per second, and agentic search explores large codebases in parallel. It also hosts a handful of open models, such as DeepSeek V4.1 Flash, Kimi K3 and GLM 5.3. Parasail is general serving on aggregated GPUs, with any Hugging Face model available on real-time or batch tiers. In a coding product, the two would handle separate calls: a Parasail-hosted model plans and writes, and Relace applies the edits and searches the repo.
Enterprise terms differ. Relace offers self-hosted deployment for enterprises that keep code in-house. Parasail works through contracts, with a standard ZDR and SLA agreement that many customers use while moving workloads off closed-model vendors. Relace errors past 128K tokens, so a general model hosted on Parasail could act as the fallback for oversized files. For PR review pipelines, Parasail's half-price batch can run the review model across many diffs while Relace handles repo search.
What Parasail and Relace do
Parasail
Parasail calls itself the inference cloud for AI-native startups. It aggregates GPUs across about 40 data centers in 15 countries, runs some clusters of its own, and since July 2026 has deployed d-Matrix Corsair accelerators alongside NVIDIA Hopper and Blackwell, all sold through one OpenAI compatible API. It raised a $32M Series A in April 2026, led by Touring Capital and Kindred Ventures. Customers choose serverless per-token endpoints across about 40 curated models, Elastic Endpoints that scale with traffic and bill tokens at 1.25x serverless rates on selected models, dedicated deployments with negotiated latency SLAs, or batch. Its commit-to-spend model lets one commitment draw down across any model or hardware.
Example models: Kimi K3, DeepSeek V4.1 Flash, GLM-5.3, MiniMax M3
Full Parasail profileRelace
Relace started out training small, fast models that act as tools for coding agents, and by October 2026 its homepage led with open-model inference instead. It says it served 30 trillion tokens in the 30 days to late October and ranks among the top providers on OpenRouter. The hosted catalog covers DeepSeek V4 Pro, V4 Flash and V4.1 Flash, Kimi K3, GLM 5.3, GLM 5.3 Flash and GLM 5.2 over OpenAI and Anthropic compatible APIs, billed per token with no subscription. Prices run from $0.07 in and $0.14 out per million tokens on DeepSeek V4 Flash to $2.00 in and $14.00 out on Kimi K3, and Relace says it reprices often.
