Between Citrus and Code: Crafting Symbiosis in the SDK Era
There’s a Southeast Asian dish where sticky rice is packed inside hollowed lime shells. As the shells dry, they hold the rice in shape and infuse it with citrus. Later, the shells can be steeped into herbal tea. They carry traces of what they once held.
It is a perfect symbiosis. The rice becomes fragrant. The shells gain purpose beyond their first use. Each benefits, neither dominates.
But balance is everything. Too much lime and the rice turns bitter. Too much rice and the shell splits open.
OpenAI’s new Apps SDK aims for this same delicate equilibrium.
The Promise
The SDK lets developers build apps that integrate directly into ChatGPT. A scheduling app can live inside conversations. A note-taking tool can pull context from chats. A task manager can understand what’s being discussed.
For developers: instant access to millions of users, zero-friction onboarding, seamless voice integration.
For ChatGPT: richer functionality without building everything in-house.
For users: tools that understand context without endless copy-pasting between apps.
The rice becomes fragrant. The shells gain new purpose. Everyone benefits.
The Pattern That Precedes
Facebook’s Platform SDK launched in 2007 with a similar promise. Developers gained access to social graphs and viral mechanics. Companies like Zynga and Spotify built businesses on top of it. The ecosystem thrived.
Then the balance shifted. Organic reach declined. Viral channels closed. By 2012, reaching users who had explicitly chosen to follow you required payment. What began as mutual benefit became extraction.
Twitter did this with its API. Google does it with Play Store policies. Apple does it with in-house alternatives that displace third-party apps. Amazon does it to marketplace sellers.
The pattern has a name: platform envelopment. Symbiosis transforms into subsumption.
Where Balance Might Break
The shifts happen gradually, each justified by reasonable concerns.
Interface consistency for better user experience means apps must use standardized components. Custom branding fades. Everything begins to look like ChatGPT. Differentiation erodes.
Data access tiering separates basic metrics from behavioral insights. Detailed analytics — the kind needed to improve products — move to premium partnership tiers or larger revenue shares.
Native feature launches address user needs directly. When ChatGPT builds its own calendar feature, it appears first. Third-party apps still work but move to submenus. Growth stalls.
Economic dependency sets in. Apps built primarily for ChatGPT struggle to maintain standalone versions. When terms change, negotiation happens from weakness.
None of these moves individually feels aggressive. Collectively, they alter the foundation. The rice conforms to the shell rather than being held by it.
Why This Keeps Happening
Platform economics create gravitational pull in one direction. Companies have shareholders, revenue targets, fiduciary responsibilities. When a third-party app succeeds because of platform integration, and the platform can replicate its core features efficiently, the rational path is clear: build it in-house, capture the value, call it vertical integration.
This is not about intention or ethics. It is about incentive structures that make certain outcomes nearly inevitable at scale.
What Genuine Symbiosis Requires
The lime shell metaphor works because transformation happens both ways. Rice absorbs what it could not gain alone. Shells that would be discarded become tea. Neither consumes the other.
For this to work in platform ecosystems, it would require:
- Binding commitments on API pricing and access, locked for multi-year periods and not subject to unilateral revision.
- Revenue sharing that scales up as apps succeed, not down. Success should benefit both parties proportionally.
- Non-compete windows where platforms commit not to build features that directly replicate successful third-party apps for defined periods.
- Data sovereignty allowing developers to export complete user data in standard formats without penalties.
- Transparent change processes with long lead times and genuine developer input on modifications that affect their businesses.
These constraints limit platform flexibility. That is precisely the point. Symbiosis requires both parties to constrain their own optimization in service of mutual benefit.
The Scale Problem
Sticky rice in lime shells works at small scale. A few made for special occasions. Not industrialized production.
The symbiosis depends on proportion, attention, and care. Attempts to scale — pack more rice, use cheaper shells, speed up the process — cause breakdown. Rice gets compressed. Shells crack. Neither benefits.
Perhaps genuine platform symbiosis faces the same limits. Perhaps it can only exist at certain scales, with structural commitments deep enough to resist optimization pressure.
Perhaps platforms, by their nature and growth imperatives, eventually grow past the point where true symbiosis can survive.
What Success Would Look Like
OpenAI maintains open terms even when it is costly. They resist absorbing successful functionality. They prioritize ecosystem health over short-term revenue optimization. They make structural commitments that preserve developer independence.
The rice stays fragrant. The shells still make good tea. Both parties transform through the relationship without one consuming the other.
This would be rare. Platform history suggests it is difficult to achieve and harder to maintain. But difficulty is not impossibility.
What Failure Would Look Like
The familiar pattern repeats. Initial openness gives way to constraint. Successful apps are replicated by native features. Terms tighten as dependency deepens. The ecosystem becomes extractive rather than generative.
The rice stops being fragrant. It only fills space. The shells do not become tea. They remain containers optimized for the platform’s own growth.
The Question
Can platforms maintain genuine symbiosis at scale? Can they resist the economic gravity that pulls toward envelopment? Can they make structural commitments strong enough to preserve balance even when breaking them would be profitable?
Or is the lime shell metaphor fundamentally incompatible with platform economics — a beautiful idea that only works at scales platforms inevitably exceed?
The rice is being packed into shells right now. Time will reveal whether the proportions hold, whether the fragrance develops, whether the shells remember they are meant for tea afterward.
Balance is everything. Too much lime and the rice turns bitter. Too much rice and the shell splits open.
The Apps SDK is testing whether there is a third option: where both elements transform each other, and neither tries to become the other.
We will see if the structure endures, or if the balance was only imagined.
