Access to a capable AI model is not, by itself, a durable business advantage if competitors can rent comparable intelligence. In Sal Parvez’s essay about ML Systems, the proposed differentiator is the context assembled around a model: relevant information, operating rules, provenance, and deliberate exclusions. That is a thesis about where value may accrue—not proof that context always matters more than model capability.
What “context” means in this argument
A context window is often treated as a capacity limit: how much text a model can process at once. Parvez uses the idea more broadly. Context is the information and operating frame available to a model when it makes a decision, including what it is instructed to do, what evidence it can draw on, and what it is intentionally not shown.

That makes the relevant question less “Which model is smartest?” and more “What does this model know for this task, under what rules, and with what evidence?” A business may rent the underlying model while building a distinctive system around the inputs, procedures, and decision boundaries it supplies.

A great deal of it is created by what you refuse to put there.” The exclusion matters because irrelevant, stale, conflicting, or sensitive material can distract a model or distort an answer. More context is not better context.

How the essay applies the idea
Different tasks need different windows
Parvez describes seven specialist “minds” using the same frontier model with different context windows and tasks. The point is that a shared model does not require a shared information environment: a system can provide each task with a narrower, purpose-built set of instructions and evidence rather than expose every agent to the same material.
Rules can shape what enters the process
The essay names three principles loaded before a task: Transparency Trust, the Lucent Lens, and Minimum Viable Expense. Parvez presents them as an intake specification that guides both human and model decisions. In this framing, rules are not decorative statements after an output; they help determine what information is admitted and how it should be used.
Provenance describes the frame, not just the model
Parvez argues that provenance should include the rules and evidence frame that shaped an output, rather than merely naming the model that produced it. He says the company publishes a signed Lucent Lens and uses a footer attribution on its pages. Those are claims about the project, not independently verified facts here; the broader distinction remains useful: a model label alone does not explain which sources, constraints, or exclusions informed a particular result.
What the reported numbers do—and do not—show
Parvez reports that an uncurated warm start cost 23% more than the cold run it was meant to improve, while a disciplined second run was 37% cheaper at the same work and quality bar. Both figures are described by the author as observations from a handful of ML Systems’ own runs—not a benchmark, and not evidence that other organizations should expect similar savings. The essay’s framing question is: “So the question is not whether AI is valuable. It is where the value goes once the intelligence is identical for everyone who pays for it.”
The same caution applies to the essay’s broader project claims. Parvez labels an 80–90% material-recovery target as modeled, not achieved, and describes a two-day sequence as aspirational. He says no ML Systems deconstruction has yet been performed and characterizes the company as bootstrapped and pre-revenue. Results from one company, one state, and one industry cannot establish a general rule about AI economics.
Practical ways to manage context
Curate for the task
Start with the decision or output required, then select the instructions and evidence that bear on it. Keep unrelated material out of the active prompt and retain information elsewhere until a task needs it. This is a practical discipline, not a guarantee of better answers: the selected sources still need to be accurate, current, and sufficient.
Structure long inputs and ground claims
Anthropic’s official prompting guidance recommends placing long-form data near the top of a prompt, above the query, for large-document tasks involving 20,000 or more tokens. It also recommends structuring documents with XML tags and source metadata, and asking the model to identify relevant quotations before carrying out the task. These are Anthropic’s vendor-specific recommendations, not a universal law about every model or workflow. See Anthropic’s prompting best practices.

Carry useful state forward instead of endlessly expanding one prompt
Anthropic’s documentation describes work that continues across multiple context windows. That makes context management a question of saving and retrieving relevant state, not simply fitting everything into one enormous session. Support varies by model and changes over time, so check the provider’s current documentation before relying on a particular feature.
Account for context cost
Context size can affect economics as well as relevance. In Anthropic’s documented Claude Sonnet 4 1M-token context offering, requests above 200,000 input tokens incur long-context pricing, and all input tokens in a request above that threshold are billed at that tier; prompt-caching modifiers may also apply. This is specific to that provider, model, and offering, not a pricing rule for AI services generally. See Anthropic’s pricing documentation.
A practitioner article from Massu AI similarly argues for finite context budgets, task-specific retrieval, and keeping unrelated history in persistent storage until it is needed. It is a practitioner’s account, not independent benchmark evidence for broad performance claims. Read the Massu AI article.

Whether or not a company adopts Parvez’s thesis, a context strategy can be assessed against four practical questions:
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minute- Relevance: Does each included instruction or source help with the current task?
- Governance: Are the inclusion and exclusion rules clear, and can people understand why evidence was used?
- Cost and latency: Does the added context justify its impact on processing time and, where applicable, usage charges?
- Retrieval and continuity: Can the system retrieve needed information and carry forward useful state without loading unrelated history into every session?
These checks turn “context is valuable” from a slogan into an operational question: what information changes the decision, and what does it cost to provide it?
Where the thesis is strongest—and where it remains open
The argument is strongest as a reminder that model access can be replicable while an organization’s curated knowledge, rules, and workflows may be harder to reproduce. Anthropic’s published guidance supports specific practices for long-document prompts and work across context windows, while its pricing documentation illustrates that very large inputs can have different costs.
That evidence does not prove context curation always outweighs model quality, nor that any particular set of principles creates a competitive moat. Model capability, source quality, retrieval, governance, and cost all matter. The essay’s title is best read as a challenge to examine where an AI system’s value comes from—not as a claim that AI models have no value or that more context automatically creates more of it.
