    RT @base10_: We talk a lot about which AI model is best. But if you're building with AI, there's another question worth asking: Why should every inference request cost the same when providers can compete to serve it? That's the idea behind Liquid Inference. It's an AI inference exchange where providers compete to serve requests, and the lowest-priced offer that meets your requirements gets selected. You keep your existing OpenAI-compatible setup, change the base URL, set your limits, and route requests through the exchange. No need to rebuild your application around a completely new workflow. What interests me most is the idea behind it: AI infrastructure where providers compete for your requests instead of developers simply accepting a fixed price. As AI applications grow, the economics of running them matter just as much as the models powering them. Worth exploring if you're building with AI.

    Liquid Inference is serving 10B tokens/day and growing 200% week over week. Most of the traffic is agents and long chats. Across 470k charged jobs, 88.7% of input tokens were cache reads. Here’s how our matching algorithm prices offers with cache hit rate included: In multi-turn and agentic workloads, the biggest cost and latency wins come from prefix/KV cache reuse. Each turn resends the full conversation, so if a provider still has that prefix in its cache it can bill those tokens at its cache-read rate, often a small fraction of the normal input rate. Naive load balancing or pure price auctions scatter a session across different providers or replicas, forcing full prefill on every turn and destroying the savings. Our matching algorithm ranks offers on the expected charge inclusive of cache hit rate rather than the full list price: 1. We measure how much of each workspace’s input repeats from one turn to the next (7-day window, at least 50 jobs). 2. We multiply that share by the measured cache hit rate of each deployment. 3. We price those tokens at the offer’s cache-read rate and subtract the expected saving from the offer’s ranking charge. 4. The deployment that served the previous turn keeps a 5% margin, so a cheaper offer has to win by more than 5% to pull a warm session away. In other words, for the right price we will abandon the cache and choose the cheaper alternative. The credit only changes the order of the offers. A wrong estimate cannot make a job cost more than its price cap. Every receipt shows the cache share we expected, the share that was realized, and the credit in dollars. That’s how we continue to improve on cache hit rate and provide the best economics for our clients’ sessions.

    RT @Architect_Fi: A benchmark tells you how a model does on someone else's task. Workloads on Liquid Inference test it on yours. Add 10 to 30 cases with the answer you expect, pick up to four lanes (models, providers, presets or Auto), and a run scores every answer and ranks the lanes by right answers and cost. A run never spends more than its limit: $0.10 by default. Guide:

    RT @OKX_Ventures: Architect submitted its comments on compute derivatives to the CFTC on October 16, followed by the Hyperliquid Policy Center (HPC) on October 20. Both support bringing regulated compute derivatives to U.S. markets, though they take different approaches to benchmark standards and the rollout of perpetuals. Around the same time, AI infrastructure credit came under renewed pressure. CoreWeave's 9.625% notes due 2032, issued in June, saw their yield climb above 15% in the secondary market. As of October 21, they were still yielding around 14.7%. How much of the risk in AI infrastructure financing can GPU futures actually hedge? @CoreWeave ended Q2 with roughly $104B in revenue backlog and $640M in quarterly net interest expense. Long-term take-or-pay contracts provide revenue visibility, while lenders also have to underwrite execution risk, refinancing conditions, and what the underlying GPUs will be worth when those contracts expire. Consider a five-year financing arrangement backed by three years of contracted compute revenue. Once those contracts roll off, the economics depend on what the GPUs can earn under new rental agreements and what the hardware would fetch on the secondary market. Rental futures could help hedge the repricing of that capacity, provided the settlement benchmark tracks the rates the operator can actually realize. That brings us to a problem with the underlying market. Much of the GPU rental market still operates through private, long-term bilateral agreements. Architect notes that even the Compute Desk H100 index it plans to use relies primarily on published quotes, with executed transactions accounting for a smaller share of the benchmark. Research from HEC Montréal found that weekly price changes in Silicon Data's and Ornn's H100 rental indices had a correlation of just 0.17 through July 2026. These indices track the same GPU generation, yet their price movements show limited alignment. The study doesn't establish which benchmark better reflects commercial rental rates, but the choice of settlement index clearly matters for basis risk. Pricing also varies across hardware generations. Architect cites Compute Desk data showing the B300 rental index rising from $4.55 in November 2025 to a reported $7.39 per GPU-hour, a roughly 62% increase. As newer GPUs change the economics of serving compute, rental rates and residual values across generations can move quite differently. The two CFTC submissions approach this market from different angles. @HyperliquidPC argues that listed futures can help an immature spot market develop common pricing standards, drawing a parallel with Henry Hub natural gas futures. It supports competing qualified benchmarks and a regulatory path for both dated futures and perpetuals. @Architect_Fi puts more emphasis on benchmark integrity and favors establishing a track record in dated futures before expanding to perpetuals. One of its proposed safeguards is particularly interesting: exclude spot transactions priced off a futures contract or the same reference index from that index's settlement inputs. Here's why that matters. As GPU futures gain traction, more commercial compute agreements could move toward index + spread pricing. A provider and its customer could agree on a rental rate tied to a published H100 index, plus a negotiated premium or discount. That would make contracts easier to price and give lenders a common reference for projecting rental income. But suppose those index-linked agreements are then reported as fresh transactions and fed back into the same benchmark. The benchmark would effectively start incorporating prices derived from itself. Futures trading could also influence commercial contract pricing, which in turn could feed back into futures settlement. Over time, the index might appear to be supported by a growing volume of transactions, even as the amount of independently discovered price information grows much more slowly. The more widely a benchmark is adopted, the more important it becomes to preserve independent price formation beneath it. This is particularly relevant for compute perpetuals. GPU-hours are non-storable: unused capacity today cannot be carried into tomorrow. That makes it difficult to establish the same kind of spot-and-carry arbitrage available in assets such as BTC. Without an expiry date, perpetuals depend heavily on funding and a reliable reference index to keep prices aligned. If that index drifts away from executable rental rates, funding can keep the contract anchored to a distorted reference. As GPU futures become more widely used in rental agreements and equipment financing, the same benchmark could influence derivatives settlement, contracted cash flows, and the valuation of GPU-backed credit. A pricing distortion that starts in a relatively thin rental market could then feed into a much larger pool of financial exposure, with the benchmark serving as the link between them.

    RT @Nate_Architect: I'm particularly excited about reservations. If we can build meaningful liquidity in short to medium term reserved capacity deals, we could save a lot of friction. Over time, I imagine most will have a hybrid approach with a base of reserved capacity for higher consequence tasks, and purchase any overflow that's more elastic transactionally. For both markets, providers will compete and you can compare on Liquid Inference.

    RT @Ishanee: If your organization is using OSS Models for internal use or needs inference for your product, this should be your go-to website. 1. Compare live offers from white-listed providers 2. Request for inference quotes (fixed rates and term lengths) 3. Match up! An example: Request 6-months of fixed price on GLM 5.3 capped at 100B tokens/day at $X/mToken.

    RT @Architect_Fi: Hard-coding a model name means a code change every time a better or cheaper model comes out. With Liquid Inference you make a preset (which models, a strategy, a price cap) and pass its name as the model: model="fast-coding". Edit the preset later. Your code doesn't change.
