Gemini API Drops Temperature, Top_p, Top_k

Miles Diallo — Wed, 22 Jul 2026 12:25:18 +0000

Google deprecated temperature, top_p, and top_k in its latest Gemini models, per the official docs and a Hacker News thread that reached 99 points and 37 comments.

The parameters are now ignored at inference time. Requests containing them still succeed, but the values have no effect on output distribution.

Model: Gemini 1.5 / 2.0 latest | Deprecated params: temperature, top_p, top_k | Status: Ignored | Docs: ai.google.dev

What Changed Technically

Gemini now uses a single internal sampling policy per model version. The previous three knobs that let developers adjust randomness, nucleus size, and token filtering no longer reach the decoder.

This removes a common source of non-determinism across runs. The same prompt and seed now produce more consistent token sequences than before.

How Sampling Works Now

The model exposes only a fixed temperature-like behavior baked into each checkpoint. Developers control output style through prompt phrasing, few-shot examples, and system instructions instead of numeric parameters.

Early HN comments noted that creative tasks previously tuned with temperature 0.9 now require explicit instructions such as "vary sentence length and vocabulary."

Impact on Reproducibility

Teams running A/B tests or evaluation suites gain stability. The same prompt yields identical token probabilities across sessions when other variables stay constant.

The tradeoff appears in creative applications. Writers and game developers who relied on temperature sweeps for variation must redesign their pipelines around prompt variation or multiple model calls.

Comparison with Other Providers

Provider	Temperature	top_p	top_k	Current status
Gemini latest	Ignored	Ignored	Ignored	Fixed internal
OpenAI GPT-4o	Supported	Supported	Supported	Full control
Anthropic Claude 3.5	Supported	Supported	Not exposed	Two knobs
Grok	Supported	Supported	Supported	Full control

Gemini is the first major API to remove all three classic sampling parameters.

Who Should Use This

Teams prioritizing evaluation consistency and reproducible benchmarks benefit immediately. Applications that need fine-grained randomness control should test prompt-based alternatives or stay on older Gemini versions while they remain available.

Practical Next Steps

Update any code that passes temperature, top_p, or top_k. Remove the parameters or set them to documented defaults to avoid future deprecation warnings.

Test output diversity by varying system prompts and example sets rather than numeric values. Measure variance across 50+ runs to confirm the new behavior matches your requirements.

Bottom line: Gemini has removed the three most common sampling controls, forcing developers to manage output variation through language instead of numbers.

The change aligns Gemini with a more opinionated inference stack. Teams that adapt their prompting discipline will see more stable results; those needing wide randomness ranges will need to evaluate other providers.

China May Restrict Overseas Access to Top AI Models

Miles Diallo — Tue, 07 Jul 2026 12:25:35 +0000

Beijing is weighing restrictions on overseas access to its leading AI models, according to a Reuters report discussed on Hacker News. The discussion thread received 14 points and 3 comments.

What the Proposed Change Involves

Chinese authorities are examining measures that would limit foreign users' ability to query or fine-tune domestic frontier models. The move targets models from companies such as DeepSeek, Alibaba, and Baidu that currently offer open API endpoints.

No final regulation has been issued. Early indications point to licensing requirements or outright blocks on non-Chinese IP addresses.

Impact on Current Users

Developers outside China who rely on these models for cost-sensitive inference face the highest exposure. Several Chinese providers currently price API calls 30-50% below comparable Western offerings.

The change would force immediate migration planning for production workloads using these endpoints.

Affected Models and Companies

Models most likely to see restrictions include DeepSeek-V3, Qwen2.5-Max, and Ernie 4.0. All three currently expose public APIs with documented rate limits and pricing.

Domestic Chinese users would retain full access under the proposed framework.

Alternatives and Comparisons

Teams evaluating replacements should compare latency, price, and context length against current Chinese options.

Provider	Model	Price per 1M tokens	Context	Notes
DeepSeek	V3	$0.14	128k	Current low-cost leader
OpenAI	GPT-4o	$2.50	128k	Higher cost, broader ecosystem
Anthropic	Claude 3.5	$3.00	200k	Strong reasoning
Google	Gemini 1.5 Pro	$1.50	1M	Longest context

Who Should Prepare Now

Organizations running customer-facing applications on Chinese APIs should begin testing Western alternatives immediately. Research groups focused on multilingual or Chinese-language tasks have fewer urgent concerns.

Hobbyists and low-volume users can continue without immediate action.

Practical Next Steps

Audit current API usage logs for volume and cost.
Set up parallel endpoints with at least one non-Chinese provider.
Monitor official Chinese government channels for draft regulations.

Bottom line: Developers using Chinese frontier models should treat overseas access as a temporary advantage rather than a stable baseline.

The policy signals a broader decoupling trend that will raise inference costs for many teams over the next 12-18 months.
