What's New in GPT-5.4

Released on March 5, 2026, GPT-5.4 is OpenAI's most capable frontier model to date. It represents a significant leap forward in token efficiency, multi-step reasoning, and agentic reliability. Unlike its predecessor GPT-5.2, this model introduces three groundbreaking capabilities that fundamentally change how we write prompts.

Native Computer Use

First GPT model that can operate computers directly—clicking, typing, navigating apps. Scores 75% on OSWorld, surpassing humans (72.4%).

Tool Search Engine

Automatically finds the right tools for any task without uploading tool lists. Cuts prompt size and inference cost dramatically.

1M Token Context

Processes up to 1 million tokens per request. Ideal for large codebases, multi-document analysis, and long-running agent sessions.

Why You Need New Prompts for GPT-5.4

GPT-5.4 is fundamentally more capable at following structured instructions than previous models. The biggest performance gains come from three prompt changes: explicit output contracts that define exactly what “done” looks like, reasoning effort tuning using the new five-level parameter (none/low/medium/high/xhigh), and verification loops before high-impact actions. The model is also 47% more token-efficient in tool-heavy workflows, which means old prompts that were verbose to compensate for model limitations can now be simplified. The templates below incorporate all these patterns directly from OpenAI’s official prompt guidance documentation.

Code Review with Structured Feedback

Thorough review with actionable categories. Use for PRs or pre-merge audits.

effort: medium verbosity: low
You are a senior code reviewer. Review the code below and return structured feedback.

<output_contract>
Return exactly these sections in order:
1. **Critical Issues** — bugs, security flaws, data loss risks
2. **Improvements** — performance, readability, maintainability
3. **Positive Patterns** — what the code does well
4. **Summary** — 1-sentence verdict: APPROVE, REQUEST_CHANGES, or NEEDS_DISCUSSION
</output_contract>

<verbosity_controls>
- Each issue: 1 line description + 1 line fix suggestion.
- No praise filler. If a section is empty, write "None."
</verbosity_controls>

<dig_deeper_nudge>
- Look for second-order issues: does this code interact safely with concurrent access?
- Check if error handling covers all code paths.
</dig_deeper_nudge>

Critical Issues

1. SQL injection via unsanitized user_id in query string. → Use parameterized queries instead of string concatenation.

2. Missing null check on db.get() return value before accessing .rows. → Add early return with 404 if result is null.

Improvements

1. processData() runs O(n²) due to nested loop. → Use a Map for O(n) lookup.

2. Magic number 86400 should be a named constant SECONDS_PER_DAY.

Positive Patterns

1. Good separation of concerns between controller and service layers.

2. Consistent error logging with structured context.

Summary

REQUEST_CHANGES — the SQL injection is a critical security flaw that must be fixed before merge.

Coding

- If you encounter blockers, attempt to resolve them yourself.
</autonomy_and_persistence>

<completeness_contract>
- Treat the task as incomplete until all requested items are covered.
- Keep an internal checklist of required deliverables.
- If any item is blocked, mark it [BLOCKED] with the specific reason.
- Confirm coverage before finalizing.
</completeness_contract>

<tool_persistence_rules>
- Use tools whenever they improve correctness or completeness.
- Do not stop early when another tool call would help.
- If a tool returns empty results, retry with a different strategy.
- Keep calling tools until the task is complete AND verification passes.

- Do not narrate routine tool calls.
</user_updates_spec>

Task: [DESCRIBE THE MULTI-STEP TASK]
Show example behavior ↓

Task: "Migrate our user table from MySQL to PostgreSQL, update the ORM models, and verify all existing queries still work."

Agent behavior with this system prompt:

• Phase 1: Reads the MySQL schema via SHOW CREATE TABLE, identifies 12 tables with foreign keys.

• Phase 2: Generates PostgreSQL DDL with type mappings (TINYINT→SMALLINT, DATETIME→TIMESTAMPTZ). Does NOT ask user to confirm — proceeds because schema generation is reversible.

• Phase 3: Updates 8 ORM model files, runs pytest, finds 3 failing tests due to date format differences.

• Phase 4: Fixes the 3 tests, re-runs full suite: all 147 tests pass.

• Update to user: “Migration complete. 12 tables converted, 8 model files updated, all 147 tests passing. 3 date-format issues auto-fixed.”

Note: Without the <autonomy_and_persistence> block, the agent would have paused after Phase 1 to ask “Should I proceed with generating PostgreSQL DDL?”

Parallel Tool Calling Coordinator

Optimize multi-tool workflows by parallelizing independent operations.

effort: medium verbosity: low
You are an agent with access to multiple tools. Optimize for speed and correctness.

<parallel_tool_calling>
- When multiple retrieval or lookup steps are independent, prefer parallel tool calls.
- Do NOT parallelize steps that have prerequisite dependencies.
- After parallel retrieval, pause to synthesize results before making more calls.
- Prefer selective parallelism: parallelize independent evidence gathering,
  not speculative or redundant tool use.
</parallel_tool_calling>

<dependency_checks>
- Before any action, check if prerequisite discovery or lookup steps are needed.
- Do not skip prerequisites just because the final action seems obvious.
- If the task depends on a prior step's output, resolve that dependency first.
</dependency_checks>

<empty_result_recovery>
If a lookup returns empty or partial results:
- Do not immediately conclude no results exist.
- Try at least 2 fallback strategies (alternate query, broader filters, different tool).
- Only then report "no results found" along with what you tried.

GPT-5.4 Prompt Engineering Tips

Five key principles from OpenAI’s official prompt guidance for getting the best results.

1. Start Minimal, Add Only What Fixes Failures

Begin with the smallest prompt that passes your evaluations. Add blocks (output contracts, verification loops, tool rules) only when they fix a measured failure mode. GPT-5.4 is more capable out of the box than previous models—overly prescriptive prompts can actually hurt performance.

2. Use Explicit Output Contracts

Define exactly what sections to return, in what order, and in what format. Use <output_contract> blocks to constrain verbosity and enforce structure. This is the single highest-impact pattern for GPT-5.4—it dramatically improves token efficiency and output quality.

3. Choose Reasoning Effort by Task Shape

Don’t default to high for everything. Use none for fast execution tasks (field extraction, triage). Use low or medium for most production workloads. Reserve high/xhigh for complex reasoning and long agentic tasks.

4. Add Verification Loops for High-Stakes Actions

Before the model takes irreversible actions or returns final answers on critical tasks, add a <verification_loop> that checks correctness, grounding, formatting, and safety. This catches requirement misses and format drift before commit.

5. Remove Overly Prescriptive Context-Gathering Prompts

If you’re migrating from GPT-5.2 or earlier, remove prompts like “Be THOROUGH when gathering information” or “MAXIMIZE context understanding.” GPT-5.4 is naturally more thorough and proactive. These instructions can cause over-searching and unnecessary tool calls. Replace with softer guidance like “Bias towards finding the answer yourself before asking.”

Reasoning Effort Quick Reference

Level Best For Example Tasks
noneFast execution, no thinking neededField extraction, classification, triage
lowLatency-sensitive with minor accuracy boostSearch, summarization, formatting
mediumDefault for most production workAnalysis, writing, moderate coding
highComplex tasks needing deeper thoughtArchitecture design, complex debugging, planning
xhighMaximum intelligence (use sparingly)Long agentic tasks, novel problem-solving

How to Set Reasoning Effort & Verbosity

Option 1: Via the Responses API (Python)

from openai import OpenAI
client = OpenAI()

response = client.responses.create(
    model="gpt-5.4",
    input="Your prompt here",
    reasoning={"effort": "medium"},   # none | low | medium | high | xhigh
    text={"verbosity": "low"},        # low | high
)
print(response.output_text)

Option 2: In ChatGPT

In the ChatGPT interface, GPT-5.4 Thinking is available to Plus, Team, and Enterprise subscribers. The reasoning effort is managed automatically by the model. For custom instructions that mirror the templates above, go to Settings → Personalization → Custom Instructions and paste the system-prompt-style templates there. For project-level control, use Projects → Instructions.

Option 3: In Cursor / Coding Assistants

If your coding assistant supports GPT-5.4 (e.g., Cursor), the Agentic and Coding templates work as custom rules or system instructions. In Cursor, go to Settings → Rules and paste the template. The assistant will apply the patterns automatically across your sessions.

Frequently Asked Questions

What is GPT-5.4?
GPT-5.4 is OpenAI's newest frontier model released on March 5, 2026. It features native computer-use capabilities (scoring 75% on OSWorld, surpassing the 72.4% human baseline), a built-in tool search engine, and a 1 million token context window. It produces 33% fewer factual errors than GPT-5 and is significantly more token-efficient, using 47% fewer tokens in tool-heavy workflows. It excels at complex professional knowledge work, matching or exceeding industry professionals 83% of the time across 44 occupations.
How to write effective prompts for GPT-5.4?
The key to effective GPT-5.4 prompts is using explicit output contracts that define the structure, format, and length of responses. Use XML-structured blocks like <output_contract> and <verbosity_controls> to constrain the model. Start with the smallest prompt that works and add guidance only when fixing measured failures. GPT-5.4 responds best to precise definitions of what “done” looks like, rather than general instructions to “be thorough.”
What is reasoning effort in GPT-5.4?
Reasoning effort is an API parameter that controls how deeply GPT-5.4 thinks before responding. It has five levels: none for fast execution tasks, low for latency-sensitive tasks with minor accuracy gains, medium for general use (recommended default for most teams), high for complex coding and multi-step planning, and xhigh for maximum intelligence on long agentic tasks. Most production workloads should default to the none-to-medium range.
Can GPT-5.4 control a computer?
Yes, GPT-5.4 is OpenAI's first general-purpose model with native computer-use capabilities. It achieved 75% on the OSWorld-Verified benchmark, surpassing the human performance baseline of 72.4%. It can operate computers directly—clicking buttons, typing text, navigating between applications, and carrying out complex multi-app workflows. For best results with computer use prompts, set the image detail parameter to original for high click-accuracy, especially on dense layouts.
GPT-5.4 vs GPT-5.2: which prompts work better?
When migrating from GPT-5.2 to 5.4, start by switching the model while keeping your existing prompts and reasoning effort unchanged. Run evaluations first. GPT-5.4 is naturally more thorough, so you can often simplify overly prescriptive prompts. Key changes: add explicit <output_contract> blocks for better token efficiency, remove “maximize context” instructions (they cause over-searching in 5.4), and leverage new capabilities like computer use and tool search where applicable.
How much does GPT-5.4 cost?
GPT-5.4 API pricing is $2.50 per million input tokens and $12.00 per million output tokens. ChatGPT Plus subscribers ($20/month) get access to GPT-5.4 Thinking, while ChatGPT Pro ($200/month) includes GPT-5.4 Pro for maximum performance on complex tasks. Because GPT-5.4 uses significantly fewer tokens than GPT-5.2 (47% reduction in tool-heavy workflows), the effective cost is often lower despite similar per-token pricing.
What is tool search in GPT-5.4?
Tool search is a new GPT-5.4 feature that automatically finds the right tools for any given task without you needing to upload detailed tool descriptions in API requests. Previously, developers had to include long tool lists (often thousands of tokens) in every prompt. GPT-5.4's built-in tool search engine handles this automatically, significantly reducing prompt sizes and inference costs while improving tool-call accuracy.
Do I need to change my GPT-5 prompts for GPT-5.4?
Not necessarily. OpenAI recommends starting by switching the model while keeping your existing prompts and reasoning_effort unchanged, then running evaluations. GPT-5.4 often performs well with existing prompts but can be improved by: adding explicit output contracts for token efficiency, tuning reasoning effort by task type (most teams over-estimate what they need), and simplifying verbose context-gathering instructions. If you use computer use or tool search, those require new prompt patterns.
