Subconscious vs Infron: key differences
Infron is a gateway: one OpenAI-compatible API in front of 400+ models from 100+ providers, at provider rates plus a 3% to 5% fee on credit top-ups, with fallbacks, region pinning and a 99.9% uptime SLA on dedicated throughput. It does not change how a model runs; it picks where the request goes. Subconscious changes the runtime itself. It prunes the KV cache and preserves suffix state so long agent traces stop rereading their whole context, and delivers 2x faster task completion and 50% to 80% lower cost than standard inference.
The billing models differ too. Infron passes through each provider's per-token price, so a long agent trace costs what it costs anywhere else, minus any enterprise discount of up to 30%. Subconscious bills tokens its system actually processes after compression, which rewards long, cache-heavy traces. Teams that need many models behind one key fit Infron; teams whose agents run past 200K tokens fit Subconscious.
What Subconscious and Infron do
Subconscious
Subconscious is an MIT CSAIL spinout in Kendall Square that builds inference for long-horizon agents, the workloads where a single trace runs past 200K tokens and often into the millions. Its runtime drops in as a replacement for vLLM or SGLang. Instead of rereading an ever-growing context on every step, it prunes the KV cache and preserves suffix state, and Subconscious co-designs the runtime with post-trained model variants it calls Marathon. Against open models on standard inference, Subconscious delivers 2x faster task completion, delivers a 5M+ effective context window, cuts cost 50% and up to 80%, and scores neutral to 10% better on agentic benchmarks.

Infron
Infron is a US-based AI gateway and inference platform. One OpenAI-compatible API reaches 400+ models from 100+ providers, including DeepSeek, Qwen, Claude, Gemini and GPT through what Infron calls official partner routes, plus media and search models. Teams set provider preferences and fallbacks, see usage and billing in one place, and can bring their own provider keys at no fee. Lawrence Xu is CEO and co-founder Andrew Zheng is CTO.
